Change SIM on FMB020

Hello, I’m trying to change the sim card to use another operator but the device doesn’t recognize it, it’s like the data from the previous operator was stored. If I use the old sim card, it has no problems. Help me please…


Good day, kindly check if the simcard supports a 2G network, the FMB020 only supports 2G.

Best Regards
Maynard C
