Even if so, it still wasn’t the standard. I’m trying to determine if that has changed and if SIM phones are the norm in the U.S. now.
Ran across this website:
A summary of the FAQ is that GSM (SIM card compatible) phone coverage in the U.S. is only offered by a few companies and then the coverage is not complete (as vast as non-GSM coverage). Additionally, U.S. GSM phones operate on different frequencies than nearly all other GSM phones from other countries. Why, when the U.S. finally got in gear on GSM, did it decide on different frequencies than everyone else, and thus end up still operating a non-standard system? Odd.
All said, it sounds like there would be very little practical compatibility between U.S. and non-U.S. GSM phones/networks.
One loose end is the whole tri-band, quad-band issue (what is it, how does it effect this topic, etc?).
