I just bought a Mudi E-750 [Affa]
I just got new phone+t mobile sim card. (I am migrating from Sprint)
I popped out the sim card from Samsung phone and put it in E750 and screen shows No service…
I am new to this. But willing to learn fast.
Thank you in Advance
AT mode? I should research this site more.
I did. I tried all modes and TTL settings as well as resetting the modem. Still no luck… device says “No service” Admin panel says "sim not registered
Does your T-Mobile SIM need a specific APN?
Also make sure the modem is AFFA by checking the modem from the UI.
Last, can you change the IMEI to the same as your phone using AT command?
