Hello to all,

I am organising an event in my town. All people participating to the event will provide their mobile phone number to me. I will make them a small surprise by sending to all of them an SMS at a very specific moment, to organise a kind of flash mob

What i need :
To program a speed dial button for sending a group SMS. So I would like to press a button from my mobile keyboard (any button is just fine) for a few seconds, which would send automatically SMS to hundreds of contacts .

I owuld purchase a mobile phone for that only time.
Do you have any idea of which phone it should be ? Cheapest is best :-)

Thank you
