Hi likhith,
CMS error 305 means invalid text mode parameter, are you sending some special character?

It works quite well in my test, below my log:

AT+CMGF?
+CMGF: 0

OK
AT+CMGF=1
OK
AT+CSCS?
+CSCS: "IRA"

OK
AT+CSCS="GSM"
OK
AT+CPMS?
+CPMS: "SM",0,40,"SM",0,40,"SM",0,40

OK
AT+CSMP?
+CSMP: ,,0,0

OK
AT+CMGS="91234567"

+CMGS: 1

OK
AT+CMGS="91234567"
> HI <ctrl-z>

+CMGS: 2

OK

As you are using WP7608, can you also try using the console tool “cm” to send SMS and see does it work? i.e.

cm sms send 7259485968 HI

Thx

Thanks

Would you please try below and capture the info?

Try to send using PDU, i.e. below for the number in your log:

AT!GSTATUS?
AT+CMGF=0
AT+CMGS=16
> 01000AA12795849586000004D4F29C0E <ctrl-z>

And to get debug legato log

cm radio
log level debug
logread -f
cm sms send 7259485968 hello

Thanks!
