What is Dual SIM DSSS/DSDS/DSDV/DSDA? Easy-to-understand explanation of the basic concepts of various correspondence methods
In the world of smartphones, Dual SIM technology has become increasingly popular. It allows users to have two separate SIM cards inserted into a single device, enabling them to use different phone numbers or plans simultaneously. However, there are different Dual SIM modes available, such as DSSS, DSDS, DSDV, and DSDA. Let’s dive into what these terms mean and how they work.
1. DSSS – Dual SIM, Single Standby
DSSS stands for Dual SIM, Single Standby. This mode allows a smartphone to have two SIM cards installed, but only one SIM can be active at a time for making calls, sending texts, or accessing data. When one SIM card is in use, the other is in standby mode, meaning it is not operational. Users can switch between the two SIM cards manually, but they cannot use both simultaneously.
2. DSDS – Dual SIM, Dual Standby
DSDS stands for Dual SIM, Dual Standby. This mode allows a smartphone to have two SIM cards installed and both can be operational simultaneously. Users can make and receive calls, send texts, and use data from either SIM card without having to switch manually. When one SIM card is in use, the other remain in standby mode, ready to receive calls or messages. However, if a call is active on one SIM, the other SIM may not be able to receive calls.
3. DSDV – Dual SIM, Dual VoLTE
DSDV stands for Dual SIM, Dual VoLTE. This mode is an advanced version of DSDS. It allows not only the simultaneous use of two SIM cards for voice calls, texts, and data but also supports VoLTE (Voice over LTE) on both SIMs. VoLTE provides better call quality and faster data speeds. With DSDV, you can have two active voice calls on two different SIM cards at the same time, allowing for a seamless user experience.
4. DSDA – Dual SIM, Dual Active
DSDA stands for Dual SIM, Dual Active. This mode takes Dual SIM functionality to the next level by allowing both SIM cards to be active simultaneously for voice calls, texts, and data. Unlike DSDS, where one SIM is in standby mode, DSDA allows both SIM cards to connect to the mobile network independently. This means that you can make or receive calls on one SIM while using data on the other without any interruptions.
In conclusion, Dual SIM technology offers flexibility and convenience to users who need to manage multiple phone numbers or plans. Understanding the different Dual SIM modes, such as DSSS, DSDS, DSDV, and DSDA, can help you choose the right smartphone that meets your specific needs. Whether you prefer the flexibility of switching manually between SIM cards or the convenience of using them simultaneously, Dual SIM technology has you covered.
