Hello @charityelaine83!

We are happy to assist you with activating your SIM card! I definitely want to make sure you get everything working properly.

To get started, please click here, and it will take you to the activations page. Make sure you chose if it’s for an AT&T Prepaid device or an AT&T wireless device. After choosing so, follow all the steps to the end and you will get your SIM card activated!

I hope this information was helpful! Have a wonderful day.

Angelina, AT&T Community Specialist
