Thanks for reading my post:-)

My problem is like this:
I installed 60 days trial version days before, and it can recongnize my Motorola E6 successfully.
But today, I uninstall and re-install the trial version, my gateway keeps telling 'Modem doesn't support SMS', meanwhile I didn't change any setting in the phone, so I can't connect a modem...

Could anybody help me out? I will be very appreciated!!

Thanks a lot~~

Hi Ning,

Are you sure you are connecting to the modem via the correct COM port?

Is there a chance that perhaps the SIM card in the modem has a PIN configured? Some modems will return unexpected error responses to the commands that we use to test for SMS support if there is a PIN configured for the SIM. So you might want to put the SIM card into a phone can confirm that there is not a PIN.

If you think that a modem supports SMS, but NowSMS is reporting an error, then you can try issuing the following commands to the modem manually via HyperTerminal (usually installed under Programs/Accessories/Communications in Windows XP ... but unfortunately not included with Windows Vista):


An "OK" response to one of the first two commands, or a "+CSMS:" response to the third, is generally enough to get past the test which causes NowSMS to report "Modem does not support SMS".

What response do you see to these commands?

P.S. - If you are using Windows Vista, then unfortunately, there's no good alternative for HyperTerminal under Windows Vista. When in a bind, I've used the trial version of Absolute Telnet, which you can find at

When using Absolute Telnet, you need to go into "Options/Properties/Connection", and configure the COM port under "Direct to COM". Then use "File/Connect" to connect to the modem so that you can send commands to it.
