What is Dual SIM?

Dual SIM is a smartphone feature that allows the device to hold and operate two SIM cards simultaneously. With two SIMs in the Samsung S20, users can enjoy benefits such as:

• Using separate phone numbers for personal and professional use
• Switching between different mobile carriers to access better coverage
• Choosing the best rates for data, calls, and texts by alternating between SIMs
• Managing roaming charges effectively while traveling

The Samsung S20’s Dual SIM capability supports either Dual SIM Dual Standby (DSDS) or eSIM, making it a versatile choice for users with different connectivity needs.

Setting Up Dual SIM on Your Samsung S20

To activate Dual SIM on your Samsung S20, follow these steps:

1. Check Compatibility: Ensure that your Samsung S20 model supports Dual SIM, as not all models do. You’ll need a compatible model (e.g., SM-G981B/DS) to use this feature.
2. Insert Physical SIM: If your model uses two physical SIM cards, use the SIM eject tool to open the SIM card tray, then place the primary and secondary SIM cards into the tray. Ensure they’re correctly aligned before reinserting the tray.
3. Activate eSIM: For models supporting eSIM, go to Settings > Connections > SIM card manager, then tap ‘Add mobile plan’ to activate an eSIM using a QR code provided by your carrier.
4. Configure Settings: After both SIMs are inserted, navigate to Settings > Connections > SIM card manager to assign preferred SIMs for calls, messages, and data.

Once set up, you can manage each SIM’s settings to tailor how calls, messages, and data usage work with each card.

Using Dual SIM on the Samsung S20

With Dual SIM, you have the flexibility to choose which SIM to use for calls, texts, and data, either by setting a preferred SIM or selecting manually. Here’s how:

Choosing SIM for Calls

When making calls, you can set one SIM as the default, or you can select which SIM to use each time:

• Set a Preferred SIM: Go to Settings > Connections > SIM card manager, then set your preferred SIM for calls.
• Manual Selection: When dialing a number, look for the option to choose a SIM card on the call screen, allowing you to pick the best option on the spot.

Choosing SIM for Data

In the same SIM card manager menu, you can assign a SIM for data usage. This is particularly helpful if one carrier offers a better data plan. When you’re traveling or trying to save on data, you can switch to the secondary SIM for data usage at any time.

Advantages of Dual SIM on Samsung S20

With Dual SIM, users can enjoy a range of benefits. Here are some key advantages:

• Enhanced Coverage: By using two carriers, you can reduce dead zones by switching to the network with better coverage in specific areas.
• Cost-Effective: Avoid roaming fees by using a local SIM card for data while traveling abroad, keeping your main SIM active for calls and messages.
• Work-Life Balance: Dual SIM allows you to use one number for work and another for personal life, making it easier to manage calls and messages across both areas.
