How to Use a SIM Card - For AT&T sim cardUpdated 24 days ago

Make sure the SIM card can use the internet on separate devices (not tied to just one phone).

The only two spelled correctly are the AT&T Broadband + NXTGENPHONE (See image).

The next step I would do is to check the information in these two APNs is typed in correctly (See table below)

If it's still not working, un-plug SIM card -> delete all APNs -> plug in the SIM card again -> see which APN shows up automatically, and use that one to try again
