feature request: If it is not done, than calculate the IMEI and it's last check digit by the Luhn algorithm

[easthvan]

Issue: A few times I experienced that GL750 Mudi could not boot and/or the celluilar interface did not start witch some randomly generated IMEIs and I was assuming that they either may be gray/blacklisted ones nad/or simply not valid by syntax?

If syntaxial validity check is not done than please consider the Luhn algorithm formula for generated IMEIs

Do you have any reason to suspect the IMEI being at fault? As far as I am aware, we're calculating the checksum.
I wonder whether the device not booting or the cellular interface not being available can be attributed to something else failing. Do you happen to have a log when the cellular interface does not come up?
