Doesn't support simultaneous voice and data but the real big one is that CDMA doesn't use a SIM card...where a CDMA device requires getting your hands on the subsidy unlock code for the device and ESN manipulation, GSM and UMTS allow a user to swap in a different company's SIM and off you go. The Breathing Effect can also be hard to predict if you're a carrier building cell sites in high traffic areas.Which is weird since the CDMA network is more advanced and has better coverage and higher bandwidth.
