After you got your new number did you go back to your phones dial pad and dial the code ##72786# to reset the new # ?
You need to go to your phone dial pad and dial ##873283# and then talk/call. This is only for iphones you will get a reset network message and another saying complete or something just say YES or Ok to both of them.
I created a topic called Changing phone # on iphone for does that don't know the pin
Hope i was able to help you.
Have wonderful holiday 🙂
What type of phone do you have?
If you like give me your phone # and pin # i can change your number for you just tell me what area code you would like since thats all i am allowed to pick. Send me a PM okay here to help if you like.
Did you try different zipcode that would give you the same area code ?
