Hello, I am working on EC25 and on some modules we have a default : they lock on LIMSRV.
Same SIM card on two modules have not same response.
On good module connection is establish and AT commands return information
AT+GMR
AT+GMREC25EFAR06A04M4G
AT+CGSN
AT+CGSN866758044603617
AT+CIMI
AT+CIMI208990000000762
AT+QCCID
AT+QCCID+QCCID: 8933999395520007627F
AT+CGREG?
AT+CGREG?+CGREG: 0,1
AT+COPS?
AT+COPS?+COPS: 1,0,“208 99”,7

On bad module AT commands responses are
AT+GMR
EC25EFAR06A04M4G
AT+CGSN
866758044563126
AT+CIMI

before we have send commands to force APN and network identifier
CGDCONT=1,“IP”,“COMLOC”
AT+COPS=1,2,“20899”,7
Can someone help me here?
Thanks in advance for every reply.
