It was noted that after upgrading from EC200AEUHAR01A12M16 to EC200AEUHAR01A24M16 becomes impossible to read SMS messages from ME memory(by at+cmgl=4). SM memory works as expected. AT command trace follows:

@Bean.Wang-Q Is there any chance to get this functionality fixed in new versions?
Do you need any more information, maybe some more logs?

Please try

at+cpms=“ME”,“ME”,“ME”

and then read the SMS from ME.

at+cpms?
+CPMS: “ME”,14,180,“ME”,14,180,“ME”,14,180
OK
at+cpms=“ME”,“ME”,“ME”;+cmgl=4
+CPMS: 14,180,14,180,14,180
OK

at+cpms=“SM”,“SM”,“SM”;+cmgl=4 works as expected.
