I work for an NGO that communicates often with our clients. The number of people total 500 and since almost all of them have mobile phones, we are trying to find a way to send messages to large groups of them quickly.

I know that there must be some Thai company that provides bulk SMS messages. I receive enough junk ones and "alert messages" so do exist. So far, I have only been able to find websites that offer 6 FREE SMS messages which is not very practical for us. Does anyone know of a company/website that would allow me to paste in 20, 100 or even 300 mobile phone numbers and send messages to them at a decent cost?

Thanks
