Quite right.  It was developed by ETSI, where E stands for European.
It's a brilliant implementation of mediocre TDMA technology.  Putting
the phone's identity in the SIM wasn't a new idea but they made it
work.

That has everything to do with frequencies.  AT&T (GSM) and Verizon
(CDMA) are mostly at 800MHz, while T-Mo (GSM) and Sprint (CDMA) are at
1900 MHz.  The 800 MHz carriers have much better coverage because 800
propagates better than 1900.  I have switched back and forth between
AT&T and Verizon (Tracfone resells both so you can switch phones
without losing your minutes) and AT&T works better here for the sole
reason that the tower is closer and higher up.
