Hi
I am using EC25-E module with JIO sim (India).
with firmware version EC25EFAR06A08M4G
Module gives CREG 0,1
but unable to receive/send SMS
even when we try to make a call, it says mobile is switched OFF.
Internet is working ( by using quectel-CM )
same SIM is working fine on EC20 module in another card.
can any one guide me regarding the issue.
Regards
Praveen

What SMS-related AT commands have you been using?
Basically we require SMS Receive functionality
We are unable to send any SMS to the module
and when we try to call the number, it says mobile number not reachable.
for testing I tried to send SMS from modem
AT+CMGS=“9182xxxxxxxx”
TEST SMS
+CMS ERROR: unknown error
AT+CMGS=“9182xxxxxxxx”
test sms
+CMS ERROR: 350
If I try to make a call
atd9182xxxxxxxx;
OK
NO CARRIER
after above command, CREG response is as follows
AT+CREG?
+CREG: 0,3
now modem has to be reset to get CREG: 0,1

This is text-mode syntax. Firstly, put the modem into text-mode with AT+CMGF=1
The send command itself is:
AT+CMGS="123456789"<carriage-return>
TEST SMS<ctrl-Z>
A <carriage-return> after “TEST SMS” will be taken as part of the text to be sent, and not as the termination of the send command.
The basic AT command to read all received SMSs in text-mode is: AT+CMGL="ALL"
Yes, I have done the same.
What does your send command return following your <ctrl-Z>
after couple of minutes
+CMS ERROR: 350
Almost certainly, there’s something wrong with your syntax.
The “couple of minutes” indicates a timeout. If the syntax is correct and the sending fails, an error code should be returned much sooner than that.
What are your text-mode parameters?
AT+CSMP?
PS - Is your SMSC (message centre) address correct?
AT+CSCA?
Syntax is correct, it works with other service provider SIM (Airtel)
at+csmp?
+CSMP: 17,167,0,0
at+csca?
+CSCA: “+917013075009”,145
message center address is correct, same works in mobile phone.
Modem gives +CREG: 0,1 but its not registered on network
when I try to call the modem, it says number is switched off.
Maybe the modem is data only version and the CS domain is disabled.
And so we cannot send SMS and use the ATD. For detail you need contact with local FAE and provide the qlog.
Check the which MBN is used.
