When I activated my new phone it didn’t give me an option to keep my old phone number. It then assigned me a new number. How do I get my old number back?
Was your other number also with Republic Wireless? Is that line still active?
If so, please submit a help ticket to swap the phone numbers on your two phones and then you can Cancel the extra line of service.
If your old number is with another provider then you will need to submit a Number transfer request. See here for details
