Can anyone please provide information on how to acquire a script which enables users to input their phone number and receive SMS messages to their cell phone? This is for USA carriers. The script needs to be written in PHP as it will be customized further. I'm assuming there is a way to do this without purchasing credits for each text messages via international gateways. Does anyone have a script like this which exists? I am interested in buying it if this exists.
Try clickatell they have a free API cover almost every carrier but you do need to buy the texts. You can make money by selling your texts to your users
