After you sign up for Google Fi and activate your phone, add a data-only SIM card to your account to use your cellular data on tablets and other compatible devices.
What you need to know
- Eligibility: You can add another device by ordering a data-only SIM as long as you have service activated with Google Fi.
- Cost: Cost depends on your Fi billing plan. Learn more about Fi plans. If you want to see how much your data-only SIM is using, check your data usage like you normally would. You’ll find a breakdown for each additional device.
- Tethering: Tethering from a device with a data-only SIM isn’t supported.
- Coverage: Data-only SIM cards provide coverage in 200+ countries and territories. Check our coverage map. You may notice some coverage differences from your main Fi phone. Coverage can also vary depending on your device.
- Number of data-only SIMs: You can add up to 4 data-only SIM cards. You can also use the same data-only SIM card in multiple devices.
Add another device
To add a device, first check for compatibility. Then you’ll order a data-only SIM, activate it, and get it set up on your tablet or other device.1. Check compatible devices & SIM cards
Here's a list of tablets that we’ve verified will work with Google Fi. You can also use your own phone with Google Fi.
- Android tablets running 7.0 or higher with LTE bands 2 and 4 (US versions)
- iPads running iOS 12 or higher with LTE bands 2 and 4 (US versions)
- Samsung Galaxy Tabs S2 or newer (US versions)
- Nexus 9 LTE (US versions)
- Sony Xperia Z4 (US version)
Some devices need a "nano SIM to micro SIM" adapter (see below).
Data-only SIMs may work with devices that aren’t on our list. Devices need to be unlocked and work with T-Mobile (GSM radio). You can order a data-only SIM and test it out. However, we may not be able to help activate or troubleshoot these other devices.
Note on phones: If you set up a data-only SIM with a phone, you will have access to data, but you won’t be able to make calls and texts across the cellular network.
About SIM adapters
SIM cards come in a few different sizes. Google Fi uses a "nano" SIM card. If your device uses something different, you may need a SIM adapter. A SIM adapter helps your smaller nano SIM card fit into a larger SIM card tray on your device. You can purchase an adapter online or at many electronic retailers.
Find out what SIM card your device uses
Most manufacturers list the SIM card size needed for each device on their website, so you can search to find out what size you need. For example, if your device needs a "micro SIM" you should buy a "nano SIM to micro SIM" adapter. If your device uses a "nano SIM," you don't need an adapter.
