Things To Keep In Mind

Preparing for Activation
Before activating your Tello Mobile SIM card, there are a few things that you need to do to ensure a smooth activation process. This section will guide you through the necessary steps to prepare for activation.
Checking Device Compatibility
First, it’s important to make sure that your device is compatible with Tello Mobile’s services. You can do that here and read more about Tello’s compatibility guidelines here, where we cover which phones are supported and which aren’t. Or, if you prefer you can check directly with Tello here, using this tool on its site.
Basically, if you have an unlocked 4G-capable phone, it will work on Tello’s services. If your phone is currently locked, it will not – so you’ll need to get it unlocked first.

You can also choose to bring your own phone or purchase a Tello phone. Tello Mobile offers a 3-in-1 SIM card that includes a mini (2FF), micro (3FF), and nano (4FF) SIM card, so it’s compatible with most types of devices.
