What is CDMA?
CDMA (or code-division multiple access, if you don’t want to be lazy about it) is a network technology that along with GSM were once the two main types of networks in the US.
Both CDMA and GSM (in their own ways) make it possible for for multiple calls and internet to be transmitted in one radio signal. The technology helped support the boom of cellular phone usage in the 90s.
Is CDMA better than GSM?
Not necessarily. The quality of a network tends to be more dependent on how the network was built. Keep in mind, that Verizon is a CDMA carrier, and they have been known for the quality of their networks for a long time.
How do I know if I have a CDMA phone?
If you have a phone that doesn’t have a SIM card it is a CDMA phone. That’s a pretty easy answer, no? Of course, there’s more.
Some smartphones with SIM cards while using 4G networks to connect you to the internet, might still be using GSM to connect to 2G CDMA networks for talk. Remember, if your phone is on Verizon or Sprint, it could be a CDMA phone.
Do I really need to know about CDMA?
For now, knowing if you have a CDMA or GSM phone is still somewhat relevant. However, both network technologies are getting phased out for the more superior 4G and incoming 5G networks.
Still, while relics of the old technology are still in rotation, and CDMA networks are still being used, it can beneficial for you to know a little about it, and whether your phone is compatible with CDMA or GSM.
If you have either of these network phones and you want to switch carrier, here’s a detailed set of results from:
