Tracking SMS TO EMAIL GATEWAY

everyone in the sms marketing is familiar or has heard of the method in which one uses e.g ([email protected],[email protected]) but it really difficult to find the(mms.att.net part) for the carrier i want to use, as i think it might not be even possible but i think there should be a way to track the @mms.att.net part for any carrier so i'm wondering if there is any tool that can do this. Any Help Please.

Can I ask why you would want this information like this?

i want to send mass sms to the numbers that i have. but i don't know the gateway servers of the network providers and i have checked every single list of gateways from "ALL" websites that list gateway. a website said they couldn't find it so i am wondering if there is any tool that can locate the server gateway for any network. i already saw a website but it only for us and canada
