Then again, AT&T is a Texan company, which by nature is oblivious to anything outside that state.
That's because nothing outside of Texas matters
I wouldn't be surprised if US carriers haven't expanded abroad because it's unlikely that in most places they would make the egregious profits that make in the US. It'll be interesting to see whether Softbank brings Japanese-style rates to the US market (assuming the deal goes through). They'll probably have to back it up with better coverage, though.
