Global Vs GSM – The Major Differences

When it comes to overall performance, there aren’t any significant differences between GSM and CDMA. However, it’s important to note that the usage of these technologies may vary depending on the country you are in.

CDMA devices are commonly found in the United States and Russia. Interestingly, CDMA was originally developed during World War II to ensure secure communication that couldn’t be intercepted or jammed by enemy forces.

These days, CDMA has evolved into a widely used technology for smartphones and mobile devices in the USA and Russia. CDMA devices do not use SIM cards and are tied directly to a specific network.

On the other hand, GSM utilizes SIM cards, allowing users to send messages to and from other mobile owners. GSM is the most commonly used network technology worldwide. It offers more freedom to users in terms of network selection.

Although in the past, CDMA was predominantly used by Verizon and Sprint in the USA, GSM technology has gained popularity across all four major networks, with the rapid expansion of LTE support.

GSM is considered to be the superior technology because it allows users to switch out their SIM cards and use different networks around the world, offering more flexibility and freedom.
