If you activated your BT TNT Sports benefit on discovery+ before the move, BT directs you to sign in to HBO Max with those discovery+ details. If you never activated it, use the TNT Sports activation option in MyBT and follow the prompts to create or link the HBO Max account.
Identify the seller and where you can already watch
Use these instructions if your eligible TNT Sports access comes from BT TV or BT Broadband. HBO Max offers separate instructions for other television, broadband and mobile providers. Check your existing BT product before opening a new order page.
BT says the numbered channels in the BT TV Guide were unaffected by the March 2026 streaming move. If TNT Sports 1 opens in that guide, you have confirmed the TV route. Opening a TNT Sports item inside HBO Max is a separate check of the streaming account.
If you previously used discovery+ for the benefit
Open the HBO Max app or site and sign in with the email address and password from the discovery+ account that held your sports access. If you know the email but have lost the password, use the password recovery option in HBO Max.
Once signed in, select a TNT Sports item. A successful sign-in to the entertainment home page establishes which account you opened. The sports item shows whether that account can use your TNT Sports benefit.
If you never activated the streaming benefit
HBO Max documents the MyBT route for BT subscribers. BT also describes completing the first sign-in after the activation has been linked.
- Sign in to MyBT and go to Your Products, then Your TV and Sport.
- Find TNT Sports under Monthly TV extras and choose Activate.
- Follow the instructions to create or link the HBO Max account. Review and accept the service terms when prompted.
- Open HBO Max with the account just linked and check a TNT Sports item on that device.
If the app still asks you to get access
Return to MyBT and confirm which existing service provides TNT Sports. Check the email used in the app against the one linked at activation. If a set-top-box channel works and the app still asks for access, include both results when you use BT’s account help. You can describe that distinction without sharing either password or an activation code.
