I'm not Mark, but I'll respond since I'm using the Z600 with T-Mobile in the USA... You can just pop the card out of your old phone and put it in the Z600. The guy at my local T-mobile store did that with mine while we were troubleshooting t-zones. My SIM worked flawlessly in his Siemens phone and his in mine. As for t-zones not working with the Z600...I have found that every other WAP site I try to access works just fine. The t-zones home page, however, is not yet viewable on the Z600 for whatever reason. Rest assured you can still access the rest of the WAP web. This is a known problem that T-mobile is supposedly working on. I don't find it to be a really big deal, but some people might. best-- Rob Parker
