If you have just purchased or received your new Tello GSM SIM, here is how to get the Tello service activated.

When you purchase a Tello GSM SIM Card, you receive a 3-in-1 SIM card that includes mini (2FF), micro (3FF), and nano (4FF) sizes to fit any type of compatible phone.
You receive 1 SIM card and that 1 SIM card contains the three different sized punch-out SIM options.

When the package arrives, follow these steps:

1. Go to the "My SIM" section of your Tello online account.
2. Enter your Activation Code in the provided field and follow the prompts to Activate.
3. Once the activation is processed, a new number will display on your Dashboard.
4. Then you can insert the SIM card according to the device instructions and Turn On the device to test the service.
5. If your phone does not activate automatically, please wait 10 minutes, then reboot your phone and try again.
6. Start calling, texting & surfing the web with Tello!

Tello Phone Number & Porting

Every SIM activation for a new line generates a new Tello phone number. You will see a new number provided by Tello in your online account when the activation process is completed.

You will not be able to port in a new number until you have successfully activated the SIM Card in your online account. Only after the activation is done, you can start a Port In Request that will replace the Tello number with the transferred number.

The port-in form will only become available & visible after a successful SIM activation and it can only be done from your online account.
