Frequently Asked Questions
-
How do I start using the service?
If you are new to Tello, you'll need to open a free account, build your own plan or buy Pay As You Go credit. Next, you’ll need to decide if you want to bring your own phone into Tello or buy a new one. Once your service is activated you can start making calls, texting or surfing the web.

What will the transition to GSM look like?
Existing customers will be prompted via email & account alerts when their line is ready to migrate.
We recommend that you prepare for migration by checking your current device for GSM device compatibility and check your location for GSM coverage.
If both of those pass the checks then all you will need to do is order the free Tello GSM SIM when prompted to do so in your online account. -
Will my subscription or billing date change due to the migration?
Nothing will change, except for a better-improved coverage offered by the 5G GSM network. Your plan's price, balance, phone number, or billing date are in no way affected by the migration. You will be able to enjoy the same super affordable phone plans & great Tello service.
