I’m already a Tello customer, what does this mean for me?

Improved coverage, faster data speeds, and a super-stable network with the SAME plans and pricing

Customers will be able to switch starting early 2021, they will receive notifications in My account and via email.

Older CDMA phones will work up until at least mid-2021, and we will enable a gradual switch with lots of opportunities to change trains

To best use the new GSM network, your phone needs to have, as minimum requirements LTE frequency bands 2, 4, 12 + VoLTE

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?
There will be plenty of time for current customers to switch to the new network. During this time, Tello will have service on both networks. Once an existing customer decides to switch to the GSM network, he will need to order a new GSM SIM.
Will my subscription or billing date change due to the migration?
No. Your rate, phone plan, and billing date are in no way affected by the migration. Customers will enjoy the same super affordable phone plans & great Tello service.
Are the phones available on Tello compatible with the new network?
All devices that have VoLTE in the Technology box on Tello’s website are compatible with the new network. To access the GSM network, all customers will need new Tello GSM SIM Cards.
