Lost Data coverage today

Hello everyone! So today out of nowhere I seem to have lost my Straight Talk data coverage. All troubleshooting i have tried doesn't seem to fix it. Let me start by saying my phone is the Nexus 6p, using At&t sim card. I've tried a new SIM, every APN setting i can find online, rebooted phone, reset phone to stock, safe mode, and everything else i can think of. Anyone have any other ideas on why i can no longer receive data? O and i can makes calls and send/receive SMS texts
