I want to integrate sms-sending feature into a website. The following must be met.
1. A free SMS gateway (it's ok if it is even an ad-sponsored one).
2. It must send sms to Sri Lanka specially (it's ok it does not send sms to other countries. Primary destination is Sri Lanka)
3. The cost of sending sms must be zero (therefore most probable the service may be ad-sponsored where they insert a tiny advertisement in each sms sent)
4. You don't have to develop the entire script. (I will do that). You just have to develop the bare-bone script with just sms-sending API coding.
Above work would take only a few minutes if you already know such an sms gateway (I know there are lots of such gateways on the Internet). Note that I need SMS gateway with API (SMPP or otherwise). I need it asap, or the project will be abandoned. Thanks.
