Have a number already that you'd like to use as your Sideline number? To help you out, we put together a guide for everything you'll need to successfully port your number from T-Mobile.
If you have any questions about the porting process, check out our porting FAQs.
Here's everything you'll need:
- You can usually find your account number in the upper right hang corner of any bill or invoice you have, or in your online account.
- You won't be able to find your PIN on any bill or invoice.
- Your PIN would have been given to you by T-Mobile and is usually pre-selected.
- To learn what your PIN is, you can call T-Mobile at 877-453-1304 or visit a store.
- If you're transferring from an account that has only one line, enter the number that you're transferring.
- If you're transferring from an account that has multiple lines, contact T-Mobile to find out which number is your billing telephone number.
- If you're the only person on the account, this would be you.
- If you've on a family or shared plan, the account owner's name will be in the address portion of your bill.
- This is the address that your T-Mobile bills are sent to.
