MUDI v2 can’t connect using MEO data sim in Portugal

Seems provider detects you by IMEI. Run this AT (NOT SSH) command:

AT+EGMR=1,7,"IMEI"

Example:

AT+EGMR=1,7,"352395084327731"

You can generate new IMEI using this service (link)

In this manual showed how to enter AT commands, just replace command from manual with command that I provided above.

I recommend to change IMEI with TTL. Guide (Click on “Please check the sim card and device compatibility implication“)
