I'm interested in developing an application that will allow me to send a short text message to a list of mobile phone numbers.
What's the best way of doing this?
Basically, what I want to do is provide a service where a client will send me his/her list of phone numbers and the text message. I will then take care of sending those messages through my program. It could be a few, but it can also be thousands.
I know you can do it through email, but I've also heard of different terms for this (GSRM, SMPP server, etc...).

Anyone have additional information regarding this technology?
