Sim card activation

I went to Att store in El cajon/Main street to activate my new card but there was a guy working said you should go to the store that you bought your phone and card. Nonsense!!

We understand the importance of activating your SIM card without a store visit, @picaresque.

Special thanks to our ACE, sandblaster, for their response and expertise.

Our first recommendation would be to use this resource to activate your device

Many devices use a physical SIM card that is already inserted in the device. If you use a different SIM, you might not be able to access our wireless network or use all our network features.

If your SIM isn’t already inserted, learn how to put it in.

  1. Go to Device Support.
  2. Choose your device.
  3. Scroll to Getting started and select Hardware & phone details.
  4. Choose Insert or remove SIM card and follow the steps.

Our second recommendation would be to activate your SIM card.


If you bought a new Android phone or a new SIM card, make sure the SIM card is inserted in the phone.

Just simply select "AT&T wireless" or "PREPAID" to via the blue boxes to get started.


Our third recommendation would be to choose a plan with your device


Please let us know if this helps. If not, we can continue offering you more support. Thanks for reaching out to AT&T Community Forums!

You posted in the home phone as in landline forum. Home phones don’t have SIM cards, moving to wireless. I will presume you bought a prepaid phone and sim. If so, you can activate online, you don’t need to go to a store.
