GSM stands for Global System for Mobile communications, and it’s used in nearly every part of the world. CDMA is another cellular standard that is widely used in the United States, some African countries, and Asia. It works on the same principles, but is more expensive to implement. GSM supports voice and data transmissions in parallel, while CDMA doesn’t. GSM also uses a SIM card, so your existing information can be transferred to a new phone. However, CDMA requires you to use a white-listed company to continue using their service.
Despite the similarities between GSM and CDMA, there are many differences between these two wireless standards. GSM phones require SIM cards to be activated, while CDMA phones don’t. Both standards work the same way, but they use different frequencies, and the best way to activate them is to buy a phone with a dual-standard. If you’re unsure about which technology your phone uses, make sure to compare your phone’s specifications with your carrier’s.
