I'm new to this and this may be a newbee ? but I'm hoping someone can help.
I would like to know how this works.
Example: text "prize" to 426315.
My web application receives the request and reads the word "prize", then sends the user back a text message with information on how to claim the prize.
I just want to know where the example number 426315 comes from. Is this assigned by the phone carrier?
Hope that make sense.
