Hello,
I upgraded an EC25 modem from EC25EFAR06A17M4G_20.200.20.200 to EC25EFAR06A21M4G_20.300.20.300 and the modem seems no more connecting to LTE (it works only on gsm / edge). Is it a known issue (is there another upgrade..) or what? Any suggestions?
Thanks in advance for your time.
Best regards,

Hello,

I tryed to set the commands that you suggested but it do not work..(here is the results after givin the commands to the updated modem)
AT+QENG=“servingcell”
+QENG: “servingcell”,“NOCONN”,“GSM”,222,88,38AB,6ED0,60,103,-,-50,255,255,0,55,85,1,-,-,-,-,-,-,-,-,-,“-”
OK
AT+QENG=“neighbourcell”
+QENG: “neighbourcell”,“GSM”,222,88,38AB,6ECF,57,100,-67,38,68,0,0
+QENG: “neighbourcell”,“LTE”,3350,236,-9,-1
+QENG: “neighbourcell”,“LTE”,1650,35,-8,0
OK
AT+QENG=“3gcomm”

so it sees LTE band but the current connection is GSM

Hello,
I finally found the problem: the device who control the EC25 modem was faulty.
In order to update the modem firmware maybe I damaged the holder device, so after the update the functionality of the modem has been compromised. It is my fault..
Sorry for the time you spent on this problem!
Thanks again for your support.
