Which Sim card is best for use GSM or CDMA?
I think GSM is a good one because you can use GSM SIM cards in any mobile but you can’t use a CDMA SIM card in other mobile handsets. Suppose you are going to abroad and your cell phone does not support in abroad then you should change your cell phone then you can’t insert CDMA SIM into that handset. So GSM is the best choice.
The same thing applies in the case of mobile phones. Always use GSM cell phones because you can insert any kind of SIM card into it. If you want to get an International SIM card then you can easily replace the SIM.
