I'm simply looking for a SMS gateway... The ones like what Twitter uses...
The intended audience would be globally.
Some of you would have used them and I'd really appreciate if you could share your experience.
I've Googled and the problem isn't that there is none, the problem is
that there are simply too many. Almost like looking for a webhosting. So
human 
testimonials would be very helpful here.
Any resources/links/pointers will be deeply appreciated. Thank you.
