send multiple sms at the same time

[Dennis Kober]

I tried to send a large group of approximately 1000-2000 sms per day, to arrange that I use the timer. To complete all the sms it took a long time about 5-6 hours.
I have set a timeout on nrGsm to 10000 and 10000 at the timer on each send per sms, if the value was reduced will affect that status gsm looks busy long enough.
Is there another way to send multiple sms at the same time, for example a sms delivery to about 20-30 phone numbers.
Any feedback will be greatly appreciated.

Hello

It seems like it is not right way to use ordinary GSM device for mass sms sending.
Possible better if you will find and use Web service that provide such functionality over Internet.

If want to use TnrGsm you should programming correctly without fixed delay with Timer.
After every SMS send you need to wait result of last sending, after that you can send next sms.
It will be more effective than fixed timeout.
