Hello, I am programming a mobile app which send sms. I need a gateway that let me put a "from" parameter. On many gateways, I can only subscribe, put my mobile phone number as the sender after a verification process. The main problem is that the phone number verification is only available for my and not for my users. My customers can send an sms but the receiver does not see their mobile phone number in the "from" field. Do you know a good gateway which support that (in an automated way) ? Thank you for your help.
