From what I understand, isn't CDMA in the Nordic countries on 450 MHz and only recently introduced there as a data-only option which replaced the old NMT service?

CDMA in Canada is on its way out as Bell & Telus (the traditionally CDMA-only option) now have an HSPA-only network up & running for at least the last 4 months I've heard of AT&T users being able to roam on both Rogers & Bell now (the new network is a shared network between Bell & Telus, so it seems like it's just a brand thing). You can now buy a SIM for any of Rogers, Fido, Bell, or Telus and use it with a compatible phone (ideally 850/1900 HSPA/GSM). Correct me if I'm wrong but, for CDMA in Canada, Bell & Telus never let people activate non-Bell/Telus phones on their network.

In the US, I believe Verizon at one time was allowing people to use any compatible CDMA phone, but I believe this has stopped recently. I think Metro PCS lets people bring their own compatible phones because they (usually?) use the same bands the other companies use (800/1900), so the phones should work fine. Personally, I think this is a good idea as it can cut down on e-waste at least in the short-term.

Doesn't China & possibly other Asian CDMA-using nations allow the R-UIMs in the phones? I know the R-UIM was never made mandatory (explaining why in North America CDMA operators never had to bother with it) and only came about around 2002 or so.

From what I understand, most countries that run CDMA on either 800 or 1900 MHz are or have already converted to UMTS/HSPA by now. One example was Telstra & 3 in Australia. They ran on CDMA at 800 MHz and switched it to 850 MHz UMTS/HSPA, which explains why so many UMTS bands (850, 900, 2100) are in use there compared to most other places outside the Americas (2100 w/ 900 in a handful of places?).
