What is dual 5G standby? ›

If your phone supports dual 5G standby, when using two 5G SIM cards. After 5G is turned on and the local network supports 5G, both SIMs can use the 5G network, and the 5G icon will be displayed in the status bar.

Dual SIM Dual Standby (DSDS).

Both SIM cards can receive calls or texts, but only one can be used for active data or calls at a time.

Dual-mode 5G refers to 5G support for two primary types of 5G networks: NSA (Non-Standalone Access) and SA (Standalone Access). The reason why dual-mode 5G is getting prominence is that the current set of 5G phones with Snapdragon X50 Modem (Galaxy Note 10+, LG V50 Thinq 5G, etc.) have 5G NSA support only.

About Dual SIM Dual Standby (DSDS)

Only one SIM card can handle data at a time, and you can select which SIM card you want to use. You can select which SIM card to use for making calls or sending text messages (SMS). When one SIM card is engaged in a call, the other SIM card is temporarily disabled.

The Dual Mode Operations in the OS guard it against illegal users. There are two types of operations: the user and kernel modes.

Load Balancing and Network Efficiency: Dual connectivity allows for load balancing between cells, optimizing resource allocation and improving network efficiency. The primary serving cell can offload traffic to the secondary cells, distributing the load and preventing congestion in the network.

Flexibility: Dual-mode operation allows the operating system to support a wide range of applications and hardware devices.

Dual SIM models allow you to use two SIM cards in one device. This is handy if you have separate phone numbers for work and home or if you would like to use a local number while keeping your original number active when in a foreign country.
