Why Dual SIM and eSIM Are Game-Changers

Modern smartphones make it easier than ever to stay connected across borders. Whether you travel for business, study, or leisure, having two numbers on one phone helps you separate personal and travel data while avoiding roaming surprises.

With Dual SIM + eSIM functionality, Latvian travelers can now keep their local number active while adding an international prepaid data plan from esim.lv. This setup offers flexibility, instant connectivity, and cost savings — all without changing your SIM card.

What Is Dual SIM and How Does It Work?

Two Lines, One Device

A Dual SIM phone allows you to use two mobile numbers at the same time — one physical SIM and one digital eSIM.

Example:

• Slot 1: Your Latvian number (for calls and SMS)
• eSIM: A prepaid travel data plan from esim.lv

This setup means you can receive calls on your local number while using low-cost data abroad through your eSIM.

Check whether your device supports eSIM via Apple’s eSIM compatibility guide.

How to Set Up Dual SIM & eSIM on Your Phone

Step-by-Step Setup

1. Buy your eSIM plan at the esim.lv Shop.
2. Open your phone settings → Mobile Data / Cellular.
3. Tap Add eSIM or Add Mobile Plan.
4. Scan the QR code received via email.
5. Label each SIM (e.g., “Latvia” for your local SIM, “Travel” for your eSIM).
6. Choose which SIM to use for data, calls, and messages.

That’s it — your eSIM activates instantly, and you can use both numbers simultaneously.

Benefits of Using Dual SIM + eSIM

Perfect for Frequent Travelers and Remote Workers

Using an eSIM alongside your main number brings several advantages:

• Keep your Latvian number active for incoming calls.
• Use eSIM for cheap, high-speed data abroad.
• Avoid SIM swaps or losing cards during travel.
• Manage work and personal lines separately.
• Switch easily between networks when one is weak.

You can also set your phone to automatically pick the strongest network — ideal for multi-country trips across Europe or Asia.

Best Scenarios for Dual SIM + eSIM Use
