Hello,
yesterday my GL-X300B-GPS arrived from amazon.
Unfortunately it does not connect with 4G. I got following message
SIM card cannot be registered. Please check: 1. You are using the compatible modem for your carrier; 2. Whether a specific APN or data plan is required.
I ve tried two SIM cards from Vodafone, PIN is not needed. Both SIM card are working in my mobile phone
I ve connected both 4G antennas

You could try mac cloning. It’s possible your provider blocks modems. You can easily do this in the GL panel, under network/mac address. There choose “clone” & select your current mobile phone

I am sorry to hear that.
As XE300 can work, X300B should also work with the same SIM. If you still have the device, can I do a remote check?

I am very sorry that for some reason, this information was put into the dustbin, so did not reply in time.
Please help check the following situations:
1,Check to see if the antenna is OK?
2,Check if APN is correct?

Hi shab256:
I didn’t see your device on the cloud platform. Are you sure you shared it?
I am having the same issue with my unit. Were you able to get it working?
