48 hour hold on the new account. I cannot access ATT account or add more lines.

Hello @xxakashxx17, this is not the experience we want you to have, and we're happy to help with information to resolve your account concerns. 

We take your account privacy seriously. If you attempted to add new lines to your account, it may be required to validate a one-time PIN to complete the Add-a-Line transaction. We understand how frustrating this may be, and we want to provide you with the steps to take to complete adding a line to your account after 48 hours have passed. 

• Keep in mind a credit evaluation is performed to determine if a deposit is required. Once your account is set up you can visit our Add a Line help page and click "Get Started" to begin the add a line process.
