3. When you turn on your SIM card, you can connect to the AT&T network. This gives you network coverage, so you can talk and use data anywhere AT&T services are available.

5. Service Features: When you activate your SIM card, you can use AT&T’s service features, such as voicemail, call forwarding, and other network-related features.
6. Roaming and International Use: You need to activate your AT&T services before you can use them while travelling or in other countries. This will make sure that you can roam and connect without any problems. Activated SIM cards let you use your phone services when you’re not connected to your home network.
7. Emergency Services: If there is an emergency, having an active SIM card lets you make emergency calls and get important alerts, which is good for your health and safety.

Conclusion

Are you in need of activating a new SIM card that you recently purchased from AT&T? Activation can be accomplished with just a phone call, provided that the person making the call is either the owner of the account or a retail authorised user.

When you go into a local AT&T store, a retail authorised user is the person who calls to activate your SIM card. This typically takes place behind closed doors when you are purchasing a new phone. It is not necessary for you to be concerned about this procedure if you buy a new phone from AT&T because the SIM card will be included in the package and will already be activated.
