Understanding Dual SIM Technology

Before we dive into the specifics of the Samsung Galaxy S21, let’s take a brief look at what dual SIM technology entails. Dual SIM, also known as Dual Standby or Dual Active, allows a single device to support two separate SIM cards, each with its own unique phone number, account, or network. This feature is particularly useful for individuals who need to manage multiple phone numbers, such as work and personal lines, or for those who travel frequently and require access to different networks.

Types of Dual SIM Implementations

There are two primary types of dual SIM implementations:

Dual SIM Dual Standby (DSDS): This type of implementation allows both SIM cards to be active simultaneously, but only one can be used for voice or data transmission at a time. When a call or data transmission is initiated on one SIM, the other SIM becomes inactive.
Dual SIM Dual Active (DSDA): This type of implementation allows both SIM cards to be active simultaneously, and both can be used for voice or data transmission at the same time.
