I’m dealing with some problems with some clients at Portugal. There some stations are returning the CEER 232 error code when the modem is trying to perform APN connection in a UMTS network.
Which firmware version are you using?
+CEER 232 error code: PDP Deactivation cause GMM abort
Please make sure the SIM card network on the SL8080 module is working properly.
Can you share your AT command log file?
I hasn’t been receive the log files from our customer. Well, I think that this issue can be closed. If I receive additional information from mine customer, I’ll reopen this ticket.
