gsm-vs-global

Want to know whether your smartphone uses GSM or CDMA or want to know what the differences are between the two? Read through this article to find out.

GSM and Global (CDMA) are essentially different types of mobile technologies used by mobile devices across the world. Do note that in this article Global is referred to as CDMA as that is the same thing.

Global Vs GSM - The Major Differences

In terms of overall performance, you won’t find any noticeable differences between GSM vs CDMA. However, there are some limitations depending on which country you’re in.

Typically, CDMA devices are found commonly in the United States and Russia. Interestingly, CDMA was originally developed during World War II as a technology that could be used to communicate without axis forces being able to intercept or jam signals.

CDMA devices do not use SIM cards and are instead tied directly to a specific network.

GSM, on the other hand, uses a SIM card to allow a user to send messages to and from other mobile owners. GSM is the network we see most commonly throughout the world.

These days, the United States has started to use GSM technology more commonly to give users more freedom over the network they use.

In the past, Verizon and Sprint would use CDMA in the USA, whilst AT&T and T-Mobile used GSM.

With the fast spread support of LTE, more smartphones in the USA are moving over to GSM from all four networks.

GSM is considered to be the better technology - you can switch out your SIM card to use other networks across the world, and you’re given more freedom over which network you use.
