MR1100 suddenly cannot connect to cell service

My Netgear Nighthawk MR1100 suddenly can’t connect to cellular service. It was working fine before, but now there’s no signal, and it just shows "No Service" or keeps searching. I’ve already tried rebooting and reseating the SIM card, but no luck.

Has anyone else experienced this? Any tips or fixes would be appreciated.

If you're replying to someone else who said this, here’s a good response you can give:

Sorry to hear your MR1100 lost cell service. Here are a few things you can try:

1. Restart the device – You’ve probably already done this, but sometimes a full power cycle helps.
2. Check SIM card – Make sure it’s seated properly and not damaged. Try the SIM in another device if possible.
3. Check APN settings – Go into the MR1100’s settings and ensure the Access Point Name (APN) matches your carrier’s.
4. Check for firmware updates – Sometimes an outdated firmware can cause connectivity issues.
5. Manual band selection – Log into the admin panel and try selecting a specific LTE band that your carrier supports.
6. Test location – It might be a local tower issue. Try a different location if you can.

If none of that works, your device might be blacklisted, have a hardware issue, or there could be a carrier-side block or provisioning problem. Try contacting your mobile carrier for help as well.

Let me know what you've tried, and I can help further!
