Hello.

"IMEI Status: NG" means, that there is a problem with device IMEI Cert. Try to find and write another correct IMEI Cert.

If IMEI status is OK, and the problem with network is still the same, currently we don't have another solution for this device. Try to write another firmware. Also this can be HW issue.
