I am looking for a SMS gateway through which I can send SMSes in multiple countries (and multiple operators in a country). This is a requirement for a webapp I am working on. Please suggests some good (read reliable and economical) SMS gateways which you have used/heard of.
It gives you reach to more than 200 countries (reaching multiple operators on each country) and Long Numbers for inbound traffic in a few countries. The REST API is very simple to connect and SMPP is also supported.
Tropo.com and Twillio.com. Their international rates are expensive though. For India, there's kookoo.in. There might be other similar localized telephony services.
