Hi, Jaren,
Delivering SMS-to-SMS would be impractical and prohibitively expensive. =
This is for an iPhone messaging app that optionally delivers messages to =
SMS recipients for free. The business model depends on email-to-SMS =
gateways.
Like you, we were able to deliver messages in low volumes, but as the =
app became increasingly popular (at one point in the Top 20 in the App =
Store) the volume exceeded a opaque-to-us rate limit at Tmobile, but not =
at other mobile providers - some of whom we're sending many more =
messages than we ever tried to deliver to Tmobile.
Two examples out of thousands:
