I just changed my number, and I have no service. I looked up my account online, it reflects the change. I restarted my phone several times. I make an outgoing call and Sprint asks me to buy a prepaid pin to complete the call. My plan is current and paid for. I never would have changed my number if it was going to be such a huge problem!
Re: New phone number on existing phone - no service
Hello. If you have an Android, please reprogram the device dialing the code ##72786#. If it is an iPhone, please dial ##873283#. This should program the phone to work with your new number. Your personal info (or files) will not be deleted. Your network profile (which connects your phone to our network) will be reset to factory defaults (deleting the old number from your phone), and then it will automatically repopulate with your new number.
