1
Purchase a prepaid phone that does not use Sprint as the service provider.

2
Call your new cell phone service provider to activate your prepaid phone, using the contact information that came with your new phone.

3
Request that your prepaid cell phone service provider contact Sprint to transfer your old phone number to your new prepaid phone. They will confirm your identity, and then process your request.

4
Check to see if the new provider charges a fee to port your old phone number over to your new prepaid cell phone. They are permitted to charge you a just and reasonable service fee.

5
Do not cancel your service with Sprint until you are positive that the number has been successfully ported to your prepaid phone.
