I need a custom sms script that allows a user to input an unlimited amount of numbers into a text box, each number on a different line, and send mass text messages. I also need it to automatically identify the carrier so the user doesn't need to input the carrier.
Hey, I might be able to help you with this. The hardest part of this script would be auto-identifying the carrier. I'm assuming you want to auto-detect the carrier and use one of those gateways to send the text for free. This is not ideal. Ideally, you'd use a sms gateway that handles the hard stuff for you. They'd charge you a few cents a text message, but it's really the only proper way to go about this. The first option (auto-detect/free gateway) will only work with some carriers, and will cost much more in the short-term. Anyways, I'm willing to help you design and build this script if you'd like. US based, several years experience with PHP, etc., etc.. Looking forward to working with you!
