Hi!
After some time I discovered that "Сellular" info block is empty. And I am getting a lot of errors that "Unknown error occurred. Please check the network environment or reboot the device." on the INTERNET page.

Could you please provide the whole log file to us? Since the log you posted, probably unable to locate the issue.

Did you manually install some plugins in the E750v2?
Or try to reset the firmware to check it again.

Since seems the RAM free is lacking.
