If your iPad or Android® tablet uses a SIM card, it may already be activated. Just make sure the SIM is inserted.
Still no connection? Activate it now.
If your iPad uses an eSIM, you may be asked to install a cellular plan when you set it up. If you aren’t asked, you can install one now:
1. Open Settings.
2. Select the notification AT&T Cellular Plan Ready to be Installed.
3. Follow the prompts on your device to add a cellular plan.
If you can't download your eSIM with these steps, activate your iPad first.
