“Please explain what GSM and CDMA mean, the merits of both and what it means if a phone has both.”

• GSM and CDMA are different ways to accomplish the same goal, and the fact that extremely popular networks are built on each simply proves that it’s the quality of the network, not the standard, which is important. For instance, in the United States, two of the four major carriers (Verizon and Sprint) use CDMA while the other two (AT&T and T-Mobile) use GSM.Technically, neither is the better in terms of quality, but there are some things here for your consideration. GSM phones are able to be unlocked and moved between carriers, but CDMA phones are often locked to a single carrier and unable to be transferred.Hope this helps.
