Understanding CDMA and GSM Technologies

Before diving into the compatibility of Verizon and T-Mobile SIM cards, it is essential to understand the underlying technologies used by these carriers.

Verizon operates on a CDMA (Code Division Multiple Access) network, while T-Mobile uses GSM (Global System for Mobile Communications) technology.

CDMA and GSM are two different standards for transmitting voice and data over cellular networks.

CDMA networks assign unique codes to each call, allowing multiple calls to be transmitted simultaneously over the same frequency.

On the other hand, GSM networks use time division multiplexing to divide calls into time slots, enabling multiple calls to share the same frequency.

Due to these fundamental differences, CDMA and GSM networks are not directly compatible with each other.

However, modern smartphones often support both CDMA and GSM technologies, allowing them to be used on different networks.
