I ran an older version (5.51) of nowsms with a license installed. To test the new version I uninstalled 5.51 and installed the latest version.

I've now rolled back to to 5.51 but now the Modem (Siemens) won't intialise.

I can detect the modem and it installs properly but now get the following error message:

Modem does not support SMS
+CME ERROR: 11

It's the same modem that worked flawlessly for a few years.

I've deleted the modem from the Windows config, reboot the modem, etc. but still get this error.

Any ideas?

Hi Jannie,

I can't find any documentation for error code 11.

We've collected a pretty comprehensive list of these error codes from the ETSI and 3GPP specifications in the following thread: http://support.nowsms.com/discus/messages/1/829.html

But I haven't seen error 11.

You could try editing SMSGW.INI, and under the [Modem - xxx] header, add CommandPreInit1=AT+CFUN=1

Does that make any difference? (Note that you should update from v5.51 to v5.51k to try this ... http://www.nowsms.com/download/latestpatch.zip, because I'm not sure that this INI command was supported in v5.51.)

If that doesn't make a difference, then I'd suggest putting the SIM into a phone, and making sure that it works properly sending a message with the SIM in an actual phone.

Hi,

I've updated to 5.51k and now the error message is:

Also, in smsgw.ini, there is no [Modem - ] header.

Only the following lines:

[SMSGW]
debug=Yes
WebAuth=No
WebMenu=Yes
WebPort=8800
ReceiveSMS=Yes
ReceiveMMS=No

I also tried creating a modem with the init string but that also did not work.

When I take the sim out and put it in a normal phone, it works fine. I also disabled the pin on the sim.

What I did notice was getting the same error message with or without PIN, when pin was still active on modem.

500 is an unknown error.

Ok ... so you are trying to add the modem to the system, and it is failing the initialisation test. (That is why the entry is not already in SMSGW.INI.)

I'm not sure what to suggest ...

Try using HyperTerminal, and issue the following commands

ATE1V1
(Modem should respond OK - this command just turns on echo back so that you can see what you're typing)

AT+CFUN=1

AT+CSMS=0

(This above command is the one that I believe is failing)

AT+CMGF=0

AT+COPS?

AT+COPS=?

What responses do you see?

If I add a modem from NowSMS, it does come back with a "Modem Initialised" message before it fails on the SMS test.

Here are the outputs:

AT+CFUN=1
OK

AT+CSMS=0
+CMS ERROR: 500

AT+CMGF=0
OK

AT+COPS?
+COPS: 0,0,"VodaCom-SA"

AT+COPS=? (HAD TO ENTER TWICE)
+CME ERROR: 100
--------------------

It does seem the modem is responding directly with the error message. What I find strange is that I only did the upgrade / downgrade bit. I was not even at the system (VNC'ed into it to do the upgrade), so I'm pretty sure nothing changed on the hardware side.

That is strange that it is only the AT+CSMS=0 command that is returning an error ... and the modem appears to be ok, and connecting to Vodacom.

(AT+COPS=? takes awhile to complete, so hitting enter twice might have aborted the command, triggering the error there. That's probably nothing to worry about.)

Let's try AT+CSMS? ... and AT+CSMS=? ...

I'm still completely puzzled, but maybe these variants will provide a clue.
