Won't make calls

Google Fi says it only works with Android phones and iPhones, set up in its own app, so this phone can't use it.

Last checked 16 October 2026.

We can't yet confirm any of the phones we list make calls on Google Fi.

How we worked it out

2G calls: Google Fi has no 2G network.
4G bands: Shares 4G bands with Google Fi: B4.
4G calling: We haven't confirmed whether Google Fi enables 4G calling on this phone.

Google Fi runs on T-Mobile's network, so it uses T-Mobile's masts and bands.

About 2G: T-Mobile switched off 2G on 3 August 2026, and 3G on 1 July 2022.

About 4G calling: T-Mobile says most unlocked phones can work, but it can't guarantee phones it didn't sell and asks you to check your phone supports 4G calling.
