APN stands for Access Point Name. It is the gateway setting that tells your device which network path to use for mobile data. RelaxedSIM data SIMs normally apply the correct APN automatically, but some unlocked devices and IoT cameras require a manual setup. This page lists the exact APN details for every RelaxedSIM USA data SIM. Whether you compare this with an AT&T SIM card, a T-Mobile SIM card, or a Verizon SIM card, the APN details are identical because every RelaxedSIM data SIM connects on all three US networks.

| Setting | Value |

Frequently Asked Questions
Why does my SIM show a signal but no internet?
Check that the APN is exactly globaldata with no username or password, that data roaming is enabled, and that your device is unlocked. If the SIM was just inserted, wait one minute for the network to register.
Is the APN the same for every RelaxedSIM USA plan?
Yes. All RelaxedSIM USA data SIMs use APN globaldata with blank username and password, regardless of the data plan.
Do I need a username or password?
No. Leave both fields blank.
