Dual SIM and eSIM simultaneously: how it works and how to set it up

🔍 What is it and why you need it

Dual SIM — a mode in which a smartphone works with two numbers simultaneously. One slot — a physical SIM card (for example, Russian Beeline or MTS), the second — eSIM, a virtual card for another country. No roaming needed — calls and internet work at local rates.

⚙️ Step-by-step setup

iPhone (iOS 16+):

1. Insert the physical SIM into the tray.
2. Go to: Settings → Cellular → Add eSIM.
3. Scan the QR code from your eSIM provider.
4. Assign labels: "Russia" and "Travel".
5. In the Cellular Data section, select the active number for internet.

Android (Samsung, Xiaomi, Pixel):

1. Open Settings → Connections → SIM Manager.
2. Tap Add eSIM or Add mobile plan.
3. Scan the QR code or enter the activation code manually.
4. Specify which SIM is used for calls, SMS, and data.
5. Enable Dual SIM mode in the manager settings.

❌ Common mistakes

• eSIM does not activate — the smartphone is locked to an operator. Check that your device is unlocked.
• Internet does not work — the wrong SIM is selected for data transfer in the settings.
• QR code is not read — enter the activation code manually in the "Use code" field.
• One SIM turns off — on some Android devices you need to manually enable both cards in the manager.
