CDMA phones in europe and asia are available with RUIM or removable user identity modules. Same as SIM cards but different software loaded. There are phones available there with 2, 3, or 4, possibly even 5 card slots with 1 or 2 of them for CDMA. Verizon and Sprint don't want that in north america. It's about control and mone, not preventing fraud or other such bs.
