We specialize in consumer electronics. For this reason, it is important to know the difference between CDMA and GSM networks. These are the two main types of networks. In the US, Sprint and Verizon run on CDMA networks while AT&T and T-Mobile run on GSM networks.
It is important to note that one isn't particularly better than the other, and both ultimately provide the same services. The differences between CDMA and GSM are becoming less and less important as carriers move to 4G and 5G networks. Both technologies can now support voice and data at the same time, and both require SIM cards. So, if you're not sure which type of network your phone uses, don't worry too much about it. The most important thing is to make sure that your phone is compatible with the carrier you want to use.
Still not sure which phone is right for you? Ask us a question here or contact your carrier directly.
