What kind of SIM is required to use the Tello service?
To use our service, you need a Tello SIM physical card or a Tello eSIM. SIMs from other providers are not compatible with our network.
How to get a Tello physical SIM
Will it fit my phone? Yes! When you order a Tello SIM, you receive a 3-in-1 SIM Kit. This is a single card with three different punch-out sizes:
It’s designed to fit any compatible mobile device—you just punch out the size you need!
Switching Phones?
If you already have an active Tello SIM, you don’t need a new one to switch devices. Just pop your current SIM into any other compatible and unlocked phone, restart it, and you should be up and running within 20 minutes.
⚠️ Important SIM Rules:
Activation Window: A new SIM must be activated in your online account within 30 days of purchase. If you wait longer than 30 days, the SIM will expire and cannot be used.
Non-Reusable: A SIM card is tied to your phone number. If that phone number expires, the line is canceled or ported out, the SIM becomes obsolete, and cannot be reused for a new number.
Compatibility: Before buying, always make sure your device is unlocked and compatible with our network.
