Which one is better GSM or CDMA mobile?
This depends on where you are, but 9 times out of 10 CDMA will provide better coverage than GSM, especially inside buildings that GSM can't penetrate. GSM= work with SIMcards ( ATT,T-mobile) some areas have better coverage than CDMA (Verizon, Sprint, Alltel ect), the Problem with GSM is that its bandwith is not as fast as CDMA since Data travels quicker on CDMA's devices due to less steps to follow : GSM= Data - SIMcard - device= response CDMA= Data - Device= Response (wider bandwith as well) so i would say that CDMA is better than GSM. Although it has been very widely reported that GSM carriers have faster speeds than CDMA carriers. Such as AT&T has far faster speeds than CDMA networks while covered.
