How to pick the best smartphone based on voice plan?

CDMA operators are generally not very keen to let you go to them and bring CDMA device you bought from a rival operator, but still it can not hurt to ask. You will have a better chance of changing operator with a GSM mobile phone operator because you can usually swap a small card called SIM card from one phone to another, the SIM card identifies your unique account and you are allowed to access a specific network operator's GSM network.

After choosing a right phone, you will be able to determine from its description of what kind of network it uses (CDMA or GSM). Once you have determined what type of network you need, you can use WirelessAdvisor for what operators in your area operate such a network. Yo can go to http://www.wirelessadvisor.com/ to find which operators who have a spectrum in all major cities or in a specific US ZIP codes. It does not mean that these companies provide services; they may just only hold licensing radio spectrum. This site also list what type of network they are using, whether GSM, CDMA, iDEN, or TDMA.
