Hi zzyu2931. We'll be sorry to see you go, but that sounds like an exciting move! We've got info on requesting a deposit refund here - the only addition I'll add is that deposits are returned to cover existing balances, so if your family meets the criteria to have it refunded, you can actually apply it to your existing bill or, if your account is at a zero balance, speak with the representative assisting you regarding having it mailed instead. Either way, ultimately you'll need to Contact Us to work with a team that can access your account and help out.
Is there anything else we can do here on Support to help you prepare? Is your family planning on taking T-Mobile phones with you to use when you move?
