Hello,
I am using a sim 5320e for a project that needs to retrieve the time from the cellular network.
I have purchased a seperate sim for the project but the device seems to fail to connect to the network. when Im using my own sim card it works! (please note that my and the device's sim are from a different carrier company).
some information of what I have tried to do:
I tried running those at commands via putty on my computer (the connection to the computer was not stable and I had many disconnections).
AT+CREG?
AT+CREG=1
AT+CREG?
# the Result was creg 1,0 but I did noticed that sometimes right before the disconnection it showed creg 2,0
AT+CTZU=?
AT+CTZU=1
AT+CCLK?

I also made sure that the sim is not locked before running those command with "AT+CPIN?"
I'm living in Israel.

thank you!
