Hello again, sorry that I had lot of problem.
This is another problem that I get from my customer. He said that the modem couldnâ€™t send sms and make a dial. The error report said is +CMS ERROR: 512. And my knowledge about that error is in the GSM TS 04.08 specifies that if an incoming SMS arrives when trying to send an SMS, the outgoing SMS could be rejected. And Iâ€™m not waiting for any message that arrives or incoming call at all.
This my modem setting
