1. Prepárate para el cambio
Make absolute sure Ultra Mobile is going to work for you by checking your phone’s compatibility with our network and the cobertura in your area. Make sure you look at home as well as where you work and any other areas where you spend most of your time. For more tips on switching, you can also visit our Cómo cambiar página.
2. ¿Traerás tu propio teléfono?
If you are bringing your own phone, in addition to being compatible with our network, it must also be desbloqueado. For more information on bringing your own phone to Ultra, visit our Página BYOP.

3. Bring Your Own Number (or Get a New One)
If you would like to bring your US Mobile number over to Ultra, there are a few things you need to do before you activate your Ultra Mobile account.
Don’t cancel your US Mobile service yet
If you cancel your US Mobile account before transferring your number to Ultra, the number will be lost.
Gather essential account details
To bring your number to Ultra, you’ll need your Us Mobile Account Number, Account PIN or Number Transfer PIN and billing ZIP Code.
Getting your US Mobile account number
Your nine-digit account number should be in your US Mobile dashboard under Settings > Account, or it may be printed on your billing statement. You can also contact US Mobile customer support at (878) 205-0088 to ask them for your account number.
Get your US Mobile number transfer PIN
While on the phone with their customer support, you will also need to ask them for your account PIN or number transfer PIN.
