Hello,

we are using Nokia 30 Modem with NOW SMS. When sending SMS we often get errors like:
Retry Pending - ERROR - Modem Response (2): +CMS ERROR: 301 -- Nokia 30 (Cable) #2
sometimes also CMS ERROR: 500

Our contact at Nokia for getting a resolution wants to know how the Modem is accessed - as detailed as possible.

Can you tell me the way you access the modem for outgoing SMS? (I hope that this is not confidential information for you.)
Have you heard of this before or do you know what these errors mean?

Thanks for any help,
Wolfgang

Hi Wolfgang,

There is a list of CMS Error codes at the following link:

http://support.nowsms.com/discus/messages/1/829.html

These error codes are generated by the modem, NowSMS only reports them back.

Error "301" is highly unusual. The specifications define this error as "SMS service of ME reserved". I'm not sure exactly what that would mean ... it would seem to suggest that maybe the modem is busy and cannot process the operation.

Error "500" is the infamous "unknown error". Modems return this as a catch-all error. Our experience has been that this error code is frequently returned by modems when they lose their signal, or if the signal is weak where the modem is located. I would suggest checking the signal strength.

Regarding the detail of how the modem is accessed, you can enable the debug log in NowSMS by manually editing SMSGW.INI and adding Debug=Yes under the [SMSGW] section header. Then restart the gateway service. NowSMS will produce an SMSDEBUG.LOG as it runs, and it will contain the detailed information that you are after.
