Hello,
Need any newer firmware for:
M72E-02-NCH-STD
M72ER01A07
At the moment module doesnt reg in one of local networks until you insert some other simcard, then you insert old simcard back and it starts working for some time…
Hi,

Can I help you confirm the problem first?Please excute AT+CPIN? 、At +CREG? and AT+CGREG? ,then send the results to me.
