2022 Update: I no longer keep this page up-to-date. Tello uses T-Mobile’s network, and my page about T-Mobile’s 5G Coverage may have more recent information. My broader page about Tello’s coverage may also be helpful.
Tello is migrating from Sprint’s network to T-Mobile’s network. Tello’s coverage for newer customers comes from T-Mobile’s network. Long-standing subscribers likely receive service from Sprint’s network. However, some long-standing subscribers have opted in to migrate to T-Mobile’s network early.
Subscribers on Tello’s Sprint-based service do not have 5G access. Subscribers with service from T-Mobile’s network might have 5G coverage. At the moment, the 5G service is only available for customers with 5G-capable, Android devices.
We are currently working on making it available for iOS devices as well.
Please note, the 5G that we currently deploy is NSA (Non-standalone). This means that even when using 5G, your device will still only show a 4G LTE signal.
I expect Tello’s 5G coverage is roughly the same as the 5G coverage T-Mobile offers its own customers. Here’s a map from T-Mobile:
