In this post, by "SMS Gateway" I mean a company that receives SMS from myself (usually over a server to server SMPP socket connection), and then routes it to various carriers.

Here goes with my question. A few months back, I was told it can be unreliable for non-US SMS gateways to send SMS into the US (where I reside) i.e. the SMS sometimes never get delivered.

If this is still the case, I would be very interested to know the EXACT technical reason for this. Many voice calls originate from outside the US - when my mom phones me from England (a mobile to mobile call), she gets through, and connects EVERY time. Why not SMS?

It depends. There's limited acces to non-GSM nets in North America from most overseas carriers.

Cingular and T-Mobile are two GSM nets reacheable from most anywhere. AT&T Wireless customers, on the other hand, would only be receiving "foreign" messages when they're subscribed to international messaging, a free add-on to any plan.

The fact that voice calls go through unfortunately does not mean that the messages would.
