Dear Des,

I have the similar problem. I use the triala version of SMS/MMS gateway with 1 GSM modem (D-link). Although I added ModemSendDelay=100 and
RetryDelay=100 and MessageThrottleDelay=100 in the SMSGW.INI file, I can't send more than 1 sms per minute when I want to sent for example 400 massages.
I don't know how, but EXACTLY 1 sms per minute sent, I for exapmle first sms sent on 12:13:05 and the second on 12:14:05 and the third one on: 12:15:05 and so on.

would you please help me how can i solve this problem ?

Hi Abbas,

I've moved your message to a new discussion thread, because I do not believe that it is related to the other discussion.

The slow sending that you describe is symptomatic of an invalid license code or an expired trial version.

If you purchased NowSMS, please contact us and provide complete purchase details so that we can issue a corrected license. Contact link:

If you are running a trial version from before 2011, please download an updated trial version from our web site:

Also, check the "Serial #" page of NowSMS, and if you are running a trial version, there should be no serial numbers listed. If a serial number is listed, but you did not purchase the product, you may have downloaded NowSMS from a suspect web site. We recommend uninstalling NowSMS ... running a complete virus scan ... and then download a good trial version directly from our web site at
