Once you have created your Sideline account and chosen a temporary Sideline number, go to Number Porting in the Sideline settings.
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.
- Make sure you don't use any dashes or hyphens
- If you're on an older or linked AT&T account your account number may not be listed on your bill. You can contact at&t to find out what your account number is
- Make sure to use your cellular account number and not U-Verse, if you have it
- You won't be able to find your PIN on any bill or invoice. Your PIN would have been given to you by AT&T and is usually pre-selected.
- To learn what your PIN is you can call AT&T at 800-331-0500 (from your wireless phone), 800-288-2020 (from your landline, or visit an AT&T store)
Billing Telephone Number
- 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 AT&T to find out which number is your billing telephone number.
Account Owner's Name
- 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 AT&T bills are sent to.
