How Ultra Mobile Works

Girl using phone

Activating your new wireless plan

In just a few easy steps, you can activate your Ultra Mobile service online, in-store or even by text if you’re getting a new phone number.


Choose a plan and SIM type

Our SIM Kit includes nano, micro, and standard sizes to fit any device you have. With eSIM* delivery, you'll get an email with a QR code to activate instantly.

*eSIM requires an eSIM-compatible phone


Activate your SIM Card or eSIM

Follow the directions included in your SIM kit to activate, then decide whether to keep your number or get a new one. With eSIM, activate your plan then install your eSIM via QR code in seconds.



Insert your SIM or instantly connect with eSIM and enjoy your service!

Keep your number, or get a new one

Whichever you choose, it’s Ultra-easy to do both.

Transfer your current number

Transferring your number onto Ultra is easy. Just be sure to call your current wireless carrier and confirm the following information before you activate:

  • Account Number
  • Account PIN or Transfer PIN
  • Billing Zip

NOTE: Keep your current service active until you activate your Ultra SIM.

Get a new phone number

If you choose to get a new number during activation, simply enter your zip code, choose your language preference, choose “Activate A New Number,” and follow the prompt. It’s that easy.
