Trying to activate my sim

Hi Rob325,

The Community Forums are a public support option where other users, and AT&T, will try and assist with high level support needs. This means we won’t be able to look into account specific concerns. To get the help you need for your unique issue, please review our Contact Us page [www.att.com/support/contact-us/], and choose the best option to reach out to us. You can call, chat, or reach out via social media, and we can review your specific issue and provide you support. If you feel your issue isn’t account specific, and can be answered generally, please let us know, and we’ll be happy to help.

Thank you for contacting AT&T Community Forums,

Andrew, AT&T Community Specialist.

If the phone is locked to another carrier it will have to be unlocked first. Go into Settings to find which carrier the phone is locked to or ask your cousin.
