I need to send SMS to clients, using some database and c#. I have read that GSM modems are the way for connectivity and some buddy also told me that Its gonna cost me approx Rs.1900. Can you please tell me:
1. What are the technical points that should be considered before buying GSM modem?
2. Is there any other way for the same?
3. My GSM operator will allow me to send 1000 in a day SMS if needed?
4. Any other point?

Thanx,

Does you GSM Provider offer a Online-Service to send 1000 SMS?
Then you can try build a Bot or handle with WebRequest and Responses.

1. Will depend on your requirement such as frequency of SMS being sent and received, supported modes - text, PDU (you may need if you are programming the software yourself), and many such things.
2. You can send and receive SMS using GSM/GPRS modems. Your cell phone can also be used for the same.
3. Yes. There are bulk plans as well. You can check with different operators. Most of them provide SMS Gateway and their own interface to send and receive SMS. All you will need is a good modem.
4. Yes. Read below.
