In general, activating a SIM card with a new number is much simpler than porting in an existing number. However, before you begin, you must contact your current wireless provider to obtain your account number and password.

After that, if you have that information, you can begin the activation options, which are discussed below. Notably, if you’re on a contract, you’ll need your account holder’s first and last name, account number and password, address on file, and SSN before switching carriers.

  • Make sure that your SIM card fits the phone’s SIM slot.

As a result, even if you speak with a live customer service representative, confirm that you want to port in your number. If this is not the case, they will continue to activate your SIM card, assuming you want a new number.
