about sending SMS by writing program

Question

Exccuse me,

may I ask is there any API for sending SMS mesaages to mobile phone through programming?

If there is any, may I ask if there is any recommended one which is morer reliable and have more reasonable prices?

Answer 1

Take look at Smpp OpenSource

SUMMARY:

SMPP stands for Short Message Peer to Peer. It is a communication protocol designed for transfer of short messages between short message centre and SMS application.

Answer 2

Using SMPP is overkill unless you are planning to send smses at the speed of 50 a second or more.

For incidental sending of SMSes you can use HTTP calls to a SMS gateway. The Call will be similar to:

an example of such a gateway is clickatell
