I haven't been a heavy user of it (apart from SMS) because I've been in the US for a while where it's a bit expensive to use for voice. However, it has worked fine whenever I've needed it (with the one exception of roaming in Mexico, which is very new and unreliable, a Manx Telecom problem).

The only phones I've tried it on are both very basic - Siemens A60, A56.
