SMS Message CMS ERROR 350

IoT Modules MC/EM Series
5

Hi,

I check the SMSC number using AT+CASA for Telus card:

AT+CSCA?
+CSCA: “+16475800172”,145

OK

It looks ok because that number is from Telus short message service centre. Could you tell me what does the +CMS ERROR CODE:350 mean?

Thank you
