How to Switch to Google Fi
All of the prices above are for a single line paid monthly. Google periodically offers half off and other specials, usually only if you bring your own phone.
Activate Your Chip
Once you’ve picked your plan and signed up, Google will mail out a SIM card. It took a couple of days for my physical SIM to arrive, but I’ll gladly take the slight delay if it saves me from setting foot in a physical carrier store. If you’re using an iPhone, Google Pixel, Samsung phone, or other device that supports eSIM, you can set up Fi with an eSIM instantly.
Once your chip arrives, you’ll need to use a SIM tool to pull out the SIM tray and insert the SIM card into your phone. Then, download the Google Fi app (you’ll need to be on Wi-Fi to do this since your chip won’t connect to the network yet), and follow the steps there. If you’re porting in your old phone number, it may take a little longer. For me, after setting up a new number, Fi was up and running after about 5 minutes. That’s it, you’re done.
I have traveled and lived in rural areas for the past 7 years, and I’ve tried just about every phone and hotspot plan around—none of them are anywhere near this simple. The only one that comes close is Red Pocket Mobile, which I still use in addition to Google Fi. There are cheaper plans out there, but in terms of ease of use and reliability, Fi is hard to beat.
Using Google Fi as a Hotspot
You can use Google Fi as a simple way to add cellular connectivity to any device that accepts a SIM card, like a mobile hotspot. You’ll need to activate your Google Fi SIM card with a phone using the Google Fi app, but once the activation is done, you can put that chip in any device your plan allows. If you go with the Unlimited Plus plan, that means you can put your chip in an iPad, Android tablet, or a 4G/5G mobile hotspot. You are still bound by the 50-gigabyte data limit, though, so make sure you don’t go too crazy with Netflix.
Alternatively, consider ordering a data-only SIM. Google allows you to have up to four if you’re on the Unlimited Premium or Flexible plans, meaning you can keep four gadgets—a spare phone or tablet—connected to the internet. The caveat is that they can’t place phone calls or receive texts. You don’t have to use your phone to activate the SIM first. You can order a data-only SIM in the Plan section of your account, under Devices & subscriptions. If you have an eSIM-only device you want to connect, you can tap Connect your tablet and Fi will offer a QR code you can scan to activate the SIM.
Frequently Asked Questions
- Do I need a Google account? Yes, you do need a Google account to sign up for Google Fi, but you don’t need to be all-in on Google to use Fi. I have an Android phone, and I use Google apps since that’s what we use here at WIRED, but outside of work I do not use any Google services other than Fi, and it still works great.
- Is Google Fi tracking my every move? Yes, but so is your current provider. Google Fi’s terms of service say Google doesn’t sell what’s known as customer proprietary network information—things like call location, details, and features you use—to anyone else.
- I’m traveling and want to use Google Fi abroad. Will that work? Fi’s terms of service require you to activate your service in the US, but after that, in theory, it should work anywhere Fi has partnered with an in-country network. WIRED editor Julian Chokkattu has used Fi in multiple countries while traveling. However, based on feedback from WIRED readers, and reading through travel forums, it seems that most people are being cut off if they’re out of the US for more than a few weeks. I would say don’t plan on using Google Fi to fulfill your digital nomad dreams.
Tips and Tricks
There are several features available through the Google Fi app you might not discover at first. One of my favorites is an old Google Voice feature that allows you to forward calls to any phone you like. This is also possible in Google Fi. All you need to do is add a number to Fi’s forwarding list, and any time you get a call, it will ring both your cell phone and that secondary number—whether it’s a home phone, second cell, or the phone at the Airbnb you’re at. This is very handy in places where your signal strength is iffy—just route the call to a landline. Similarly, it can be worth enabling the Wi-Fi calling feature for times when you have access to Wi-Fi but not a cell signal.
Another feature that’s becoming more and more useful as the number of spam calls I get goes ever upward is call blocking. Android and iOS calling apps can block calls, but that sends the caller directly to voicemail, and you still end up getting the voicemail. Block a call through the Google Fi app, and the callers get a message saying your number has been disconnected or is no longer in service. As far as they know, you’ve changed numbers. To set this up, open the Fi app and look under Privacy & security > Manage contact settings > Manage blocked numbers, and then you can add any number you like to the list. If you change your mind, just delete the listing.
One final thing worth mentioning: I have not canceled my Google Fi service despite switching to Starlink for most of my hotspot needs. Instead, I just suspended my Fi service using the app. That way, should I need it for some reason, I can reactivate it very quickly.
Artificial intelligence (AI) has been the biggest talking point for IT leaders in 2025 – both the emerging capabilities and opportunities from the technology, and the challenges of implementing it at scale and in a way that delivers measurable benefits.
For the digital, data and technology leaders that Computer Weekly is privileged to talk to every week, building AI into their wider strategies and managing often over-hyped expectations just adds to the difficulties of one of the most important roles in any modern organisation.
All of that is taking place while they need to keep a tight rein on costs in a still difficult economy, and juggle skills shortages, talent development and ensuring cyber security. So, how well are they doing?
Computer Weekly gets access to some of the top technology leaders in the world – and the details they share make fascinating reading for anyone looking to develop and implement an IT strategy to improve their business, support employees and enhance their careers.
Here are Computer Weekly’s top 10 interviews with IT leaders in 2025:
The BBC’s research and development (R&D) arm serves a public purpose, which, according to director Jatin Aythora, is to make some of the technologies and inventions it creates available for free or at a really low cost. Aythora sees his job as helping to achieve technical breakthroughs that the news and media industry can benefit from, which he says BBC R&D has done for many years. Computer Weekly talks to him about self-belief and learning from different industries
The UK mapping service has moved on a long way from paper maps as it now looks to use AI to understand, interpret and derive insights from geographical data. CTO Manish Jethwa has a career-long passion for turning geographical data into useful insight, and he’s leading the organisation’s development of next-generation geospatial technologies.
As a technologist who also runs corporate operations, Thomson Reuters’ CTO believes her tech background gives her a unique edge as the business information group looks to transform its products with AI. That’s why she’s on a mission to use digital systems to transform internal processes and customer services.
Richard Masters, vice-president of data and AI at Virgin Atlantic, is an expert in enterprise data, but his career began somewhere different – space. Before moving into analytics, Masters completed a PhD in astrophysics at the University of Oxford. He is now applying his expertise in astrophysics to the nitty-gritty details of using AI to improve customer experience.
The vehicle recovery specialist is looking to AI and connected vehicle technology to enhance customer experience and get motorists back on the road in the shortest possible time. Group CIO Antony Hausdoerfer is driving the plan for digital transformation.
Digital media is core to engaging nearly two billion fans of Premier League football around the world, with data analytics and AI playing an ever-more important role. For Alexandra Willis, director of digital media and audience development at the organisation that runs top-level club football in England, the priority is to establish data-enabled experiences that keep fans just as engaged and entertained off the pitch.
Among the questions a head of technology may ponder are: what does it mean to be innovative, and, perhaps, what technology can be used to drive an innovation strategy? Given the main way people tend to place bets with Bet365 is via its mobile app, Alan Reed, head of platform innovation at Bet365’s Hillside Technology platform, talks to Computer Weekly about how generative AI changes the way people interact with computers.
Kate Balingit has been leading the digital health initiative at Mars Pet Nutrition, reporting to the company’s pet care CIO, where she is focused on commercialising and deploying artificial intelligence through well-known pet food brands such as Pedigree, Iams, Sheba and Whiskas. She talks to Computer Weekly about making AI relevant across its brands to support pet health.
Dan Keyworth, director of business technology at McLaren Racing, says his role involves running the tech at the sharp end of Formula One, all the IT infrastructure that must be deployed to Grand Prix races, and the IT that keeps the business of McLaren Racing on track.
The world of performing arts is in a completely different universe compared to the bits, bytes and IT infrastructure that Keith Nolan and the IT team at Royal Ballet and Opera spend their work time in. He talks about how IT lowers costs and helps power stage innovations for world-class performances.
Just about any monitor can work with a Mac Mini. It doesn’t need to be made by Apple or have any official certification. There’s a case to be made for using a cheap 1080p monitor with the Mac Mini, but most Mac users will want something a bit more premium. As you can see by options like the Dell 27 Plus 4K, that doesn’t have to mean overly expensive. Either way, here are the four elements to consider when shopping for a good monitor to go with your Mac Mini.
Size and resolution: 27-inch and 32-inch monitors are the most common sizes these days, and there are larger options. I would also consider a 34-inch ultrawide monitor if you like the wider, 21:9 aspect ratio with the curved shape. With Apple, resolution is king. There’s a reason it invests so much in high pixel density for every screen it sells, even down to the entry-level options like the MacBook Air. Pixel density is what gives a screen its sharpness, and you need a lot more pixels when they’re stretched out across a large, external monitor. If you want to keep the fidelity up, I wouldn’t buy anything under 4K, and bumping up to 5K or 6K on a 32-inch monitor can be helpful. You also want to consider the refresh rate here. A 120-Hz refresh rate is what the MacBook Pro has, offering smoother animation, especially in games.
Adjustability: Apple monitors and iMacs aren’t exactly known for adjustability. They often have none at all, and cost more when they do. That isn’t the best for your posture and ergonomics. Famously, the Pro Display XDR charges an extra $1,000 to add a Pro Stand with proper adjustability. For ergonomic purposes, the top of the screen you’re working on should be as close to eye level as possible, and that ranges depending on someone’s height. If a monitor doesn’t have height adjustability, you’ll have to depend on a separate monitor stand or arm. Other than height adjustment, many monitors also have a stand that can swivel, tilt, and rotate, all of which are important when using multiple monitors together. This is also needed if you want to use a second monitor vertically, which has become increasingly popular.
Ports: Even the cheapest monitors will always have HDMI as a connection, which is all you need to connect directly to the back of the Mac Mini. Some monitors have USB-C that support display, which will let you connect to one of the Mac Mini’s Thunderbolt ports. The M4 Mac Mini comes with three Thunderbolt 4 ports, HDMI, and an Ethernet jack. The M4 Pro model has the same ports, except the ports are Thunderbolt 5 instead of 4. You’ll need to use at least one of these Thunderbolt ports if you want to connect more than one external monitor. These monitors also tend to have other ports, such as USB-A. These can be useful, as the Mac Mini doesn’t have any on its own.
Image quality: Apple prides itself on the image quality of its Macs, so in the case of the Mac Mini, you’ll likely want to get something worthy of your Mac. This is especially important for content creators, photographers, and designers. So, you’ll want to consider a monitor’s brightness, color accuracy, color coverage, and contrast. While some IPS displays offer decent color and contrast, mini-LED or OLED displays will guarantee better image quality. These also have significantly higher peak brightness in HDR content, which really brings games and movies to life.
Frequently Asked Questions
Are Large Heaters More Powerful Than Small Ones?
Nope! It may seem counterintuitive, but large heaters don’t necessarily heat any better than small ones.
Whatever their physical size, most space heaters in the US and Canada deliver about the same amount of heat. Space heaters top out at 1,500 watts, which is the highest safe operating load for a 15-amp household circuit. And aside from some low-power personal heaters here and there, most space heaters you’ll find on the market are 1,500-watt heaters.
What’s more, electric space heaters are all pretty much 100 percent efficient in converting that electricity to heat. Whether directly or indirectly, nearly all of that energy will eventually become heat.
So if space heaters are the same power and the same efficiency, why are some 1,500-watt heaters advertised for small rooms and some for large rooms? This likely has as much to do with marketing as science. Pretty much every ceramic, electric-coil, or PTC heater has about the same amount of juice and thus the same ability to heat a room … at least eventually.
What differs among heaters is how and where the heat gets distributed and how fast. All other things being equal, the efficacy of a heater is mostly about whether it puts the heat where you want it to go.
What Are the Different Types of Space Heaters?
Basically all electric space heaters do the same thing: They take electricity off the grid, usually 1,500 watts of it if you’re in the United States, and turn that power into heat.
The vast majority of space heaters, including ceramic heaters and PTC heaters, are electric resistance heaters. This means they run an electrical current through something that creates resistance: maybe an electric coil or maybe a specially designed ceramic. This quickly turns electricity into heat.
Most space heaters use a fan to disperse this heat out into the world, where we all live. These forced-air convection heaters tend to be the fastest at quickly raising the temperature of the surrounding air. The air then heats you. And so while this variety heats quickly, it can take quite a bit of electricity to heat up a whole room.
Oil-filled radiators, in contrast, heat up oil that circulates inside the device, which then emits heat to the surrounding room. These tend to heat up slower but offer even and lasting heat and are very quiet. These radiators operate on the same principle as steam radiators in buildings with a boiler room. And just like steam radiators, they can get really, really hot to the touch.
Radiant heaters, such as infrared heaters, operate much like the sun or a campfire: Rather than heat the air, they heat objects or people directly by radiating energy toward them. Infrared devices heat the air only indirectly, via the objects it heats— much the same way the sun’s heat radiates off baking city streets. The glow is immediately palpable as warmth, but you’ll need to be in the path of the radiation to feel it, and the thermometer might not immediately register the warmth you perceive. Infrared heaters tend to be best at making an individual in front of the heater feel a little warmer without using a lot of energy, making them a more common decision in large and lofty spaces or outside on a patio.
Though they deliver heat differently, both infrared and oil-filled heaters are subject to the same wattage limitations, and have about the same efficiency, as electrical resistance heaters.
The same cannot be said for heat pumps, a newer technology that’s expected to provide the next generation of household heat. Heat pumps don’t use energy to create heat. Instead, they move heat energy from one place to another. Accordingly, they require far less energy than other forms of heater. But household systems cost thousands to install. And while more affordable window and portable heat pumps are ramping up, they’re not yet broadly available.
Yes, but also definitely no.
Space heaters are much safer than they used to be. Modern space heaters are heavily regulated, especially regarding exposed heating elements and automatic shut-off switches to prevent overheating. But all heating devices require caution, and so do all devices that pull a lot of energy over long periods.
The vast majority of residential heating fires start with actual fire—specifically in fireplaces and fuel burners. But space heaters accounted for more than a thousand fires in the US each year from 2017 to 2019, according to the US Fire Administration. Though this accounted for just 3 percent of heating fires overall, these led to more than 40 percent of fatalities, in part because portable heaters tend to be placed precisely where people are and because the resulting fires are far more likely to be unconfined.
So treat your space heater with the caution and wild skepticism that it deserves. See WIRED’s Guide to Space Heater Safety for a full rundown about how not to start fires or cause othr hazards. Our guide follows recommendations from federal experts at the the USFA and the Consumer Product Safety Commission (CPSC), as well as the Association of Home Appliance Manufacturers (AHAM).
But for the short version:
Don’t leave a space heater unattended. “Unattended” includes sleeping, y’all! Might we suggest a wonderful down comforter instead? When possible, safety experts also recommend you don’t leave a portable heater running unattended in a room with a baby, nor a person with mobility issues. The risk isn’t just fire but hyperthermia.
Plug your heater directly into the outlet. Don’t use extension cords or power strips with space heaters, lest you build up too much electrical load and risk a fire.
Don’t plug another appliance into the same outlet or circuit as the space heater.
Place a space heater only on the floor, on a level surface. Heat rises. You don’t need to prop up a heater on an unstable chair or table.
Keep your heater at least 3 feet from flammable objects. This includes bedding, drapes, furniture, clothes, papers, books. All of that.
Keep space heaters away from water and dampness, whether in bathrooms or in moist basements prone to dripping or flooding.
Read the manual. Manufacturers have good advice.
How We Tested and What We Tested
When it comes to testing space heaters, there are a few main questions: How safe is it? How loud is it? How quickly and evenly can it heat a room?
During intensive testing of dozens of space heaters, I lived for weeks in a home with the thermostat set to a chilly 65 degrees Fahrenheit.
I tested how well and quickly each device heated a medium-size room (14 by 14 feet), and also how well it heated a small seating area in a larger, open-format space. To test each heater’s thermostat and also measure the evenness of heating, I placed thermometers at three or more locations in each room, including behind the heater.
I tested the loudness of each device with a decibel meter at 3 feet away and verified power usage with a wattmeter. To see whether the heater’s exhaust put out painful levels of heat, I used an infrared thermometer to gauge precise surface temperatures. When in doubt, I put my own fingers on the line.
Finally, I tested safety features and basic durability. I looked at independent safety certifications, of course. But I also rudely knocked over each device to verify how the device’s tip-over protections functioned, if at all, and verified that the device started working again when set back on its feet.
To test overheat protection, I smothered each device with an old sheet to see whether the device shut itself off or whether it adjusted its power output to keep internal temperature low. After the device shut itseld off, I then checked how soon it could turn back on, if it ever did. (Some heaters gave up, in permanent complaint!)
If any device fails the tip-over or overheat tests, we don’t recommend it. If it’s significantly louder than 50 decibels at 3 feet, we don’t recommend it. If the heater breaks during routine operation, we don’t recommend it. Maddening rattles and squeaks are also disqualifying.
We keep on testing our favorites through the cold season and beyond, to see how they hold up over time. And, of course, we continually subject more heaters to our testing regimen to see if other devices can oust our current faves.
More Space Heaters I Recommend

Vornado AVH10 for $100: Vornado has an unholy variety of models that look quite similar but have different levels of loudness and different feature sets. Some are built in America, some in China. In general, the models I’ve liked best are the ones that advertise “vortex action,” a fancy name for spinning a fan into a spiral grate oriented opposite to the action of the fan. This leads to a mostly quiet and nigh-undetectable column of warm air, directed out to the back of the room, where it scatters. The TAVH10, which is basically this model but with a timer and remote, is my current favorite, though if you need neither, you can save $30 and get this.

Vornado MVH+ for $75 and Vornado VH240+ for $70: These two devices are very nearly the same device. And the previous year’s non-digital MVH was my favorite model before getting displaced by a couple newer models of Dreo and Vornado. It remains among the most silent, the most even in its heat, and among the most reasonably priced. This said, the TAV10 got a little quieter and the MVH got a little louder, and the addition of a remote and a timer makes it more attractive. This said, there are reasons to favor an analog device. Because they’re analog, the MVH and VH240 can also be regulated by a temperature-controlled power outlet in order to get the most accurate version of a thermostat.
De’Longhi Slim-Style Portable Panel Heater for $210: This electric panel heater is an interesting hybrid, with dual heat exhausts on each side but also a broad radiant heat panel. This makes for a middle ground between radiators and resistive fan heaters—heating a room much faster than a classic radiator would but still maintaining warm radiant heat over time. This said, it shares a radiator’s main fault, which is that it’s painfully hot to the touch across a large surface—but still issues the same amount of fan noise as a fan heater. Still: It may be your choice if you need to heat up a space quickly and evenly and maintain that heat over time.
Dreo MC706 for $170: New this year, Dreo’s innovative 2-in-1 fan/heater won top marks in our fan guide for its auto-shift positive temperature coefficient (PTC) technology, which moves the heater’s ceramic element aside to allow full fan airflow. Its 1,700 ft/m wind speed is a rarity among tower fans, let alone tower fan/heater combos. It’s not the strongest space heater, but it is sufficient, with five settings, 120-degree oscillation, and tip-over protection. Note that though there is a remote, there are no smart features, and it does not work with Dreo’s app.

Dreo Bathroom Heater for $60: Like Dreo’s smart wall-mounted model I far prefer, this ceramic heater comes with an ALCI plug for safe use near water. I prefer to keep bathroom heaters away from the floor, but not all bathrooms have mountable wall space. This remains a possible, though not ideal alternative, with a somewhat janky thermostat.
Not Recommended
Pelonis 16-Inch Space Heater for $65 and Pelonis 23-Inch Space Heater for $70: Both of these towers heated up quite quickly. Both were also enormously hot at the surface of their vents, with relatively little shielding from the visible heating elements. The 23-inch was significantly quieter than the 16-inch, however.
Photograph: Matthew Korfhage
Vornado VMHi600 for $200: This large cube was about as quiet as the AVH10, staying below 60 decibels, but its vent got quite hot—about 130 degrees Fahrenheit. Other Vornado models perform far better at a far lower price.
Photograph: Matthew Korfhage
Vornado Velocity Cube 5S for $100: This cube’s outer housing stayed quite cool, and the fan functionality is welcome. But its surface vent got a little hot, and the fan was a bit on the noisy side compared to other Vornados.
Vornado Velocity 5R Whole Room Heater for $125 and Vornado VHEAT for $160: Our top pick MVH from Vornado is one of the quietest space heaters I’ve tested. These were two of the loudest. The 5R topped 70 decibels. The vintage-looking VHEAT is quite lovely, but it’s also a bit of a noisemaker.
Lasko MyHeat Mini for $40: This little thing looked cute, and I thought it would be a nice desktop or under-table personal heater. But even with its low output at 400 watts, the vent got way too hot to want it anywhere near your laptop or papers.
Photograph: Matthew Korfhage
Lasko 22-inch Oscillating Tower With Remote for $80: This one failed our tip-over test when we knocked it over, blasting heat endlessly into the rug until it overheated and sent a burnt-plastic smell into the air. It did restart hours later, meaning this shutoff was a safety feature. But this tower’s a bit too tall and tippable to risk repeating these events often.
Honeywell 2-Position Heater for $45: This compact, simple, analog heater was a nice enough idea, able to rest vertically or on its side. Lord, it’s loud when its fan is in operation, though.
Honeywell Compact Ceramic Tower for $47: This Honeywell performed well in terms of fast heat and safe surface temperature. Its fan wasn’t too loud either. But the one we received had a maddening squeak each time the tower oscillated fully counterclockwise.
Gone but Not Forgotten

Vornado Sensa Cribside Heater: I loved the idea behind this Vornado Sensa Cribside Heater when I tested it: A space heater with an external temperature sensor, with therefore accurate temperature management (hard to find among space heaters!) But it’s disappeared from Vornado’s website, and has dwindled on retail sites. It’s no longer available on Amazon, but if you see it on sale at another site, I still like it.
Also tested but discontinued: Morento 26-cm Heater, Morento 40-cm Heater, Dyson HP07, many models of Vornado before the brand’s 2025 refresh.
