How to Switch to Google Fi (2025): Plans, Tips, and Advice

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.
