Your new Tello phone number will be auto-allocated based on the zip code entered & area code availability.
There is no way to control the exact prefix assigned, but the prefix will be from the area code you register.
You are free to either use the new Tello number allocated or port in your own number.

Every SIM delivery for a new line generates a new Tello phone number once activated. You will see a new Tello phone number in your online account when the activation process is completed.
However, you will not be able to port in a number (to replace that Tello number) until you have successfully activated that SIM in your online account.
Only after you have successfully activated the SIM in your online account, you can port in your own number to us by submitting a port-in.
The port-in option will only become available & visible after a successful SIM activation and it can only be done from your online account.

If you use the Tello phone number allocated but find that another caller name is still displaying from it, simply email our Customer Support team with the following information to get this rectified:

• Tello Phone Number affected
• Current Display Name
• Any Phone number where this incorrect name has appeared
