What type of modem is it?

"Modem does not support SMS" suggests that the modem is returning an error to the initialisation commands that we send to check if the modem support SMS. (AT+CSMS=0 & AT+CMGF=0)

It is strange that the modem would support these commands sometimes, but not others.

You might want to try adding the following under the modem's section in SMSGW.INI:


This is a command that tells many modems to power up GSM functionality. So if you try using it, put it in as a "pre-init" command so that it gets run before NowSMS tries the rest of its init sequence.

Other than that, it sounds like the modem is experiencing problems.
