Since your GroupMe account uses your phone number to confirm your identity, it's important to make sure it matches exactly the phone you use. To change the phone number associated with your GroupMe account, you must first log into the desktop version of the application. At that point the procedure will be quite simple and can be performed on any type of smartphone.
