1. What is eSIM?

eSIM (Embedded SIM) is a form of digital SIM built directly into your phone, tablet, or smartwatch. Unlike a traditional physical SIM, an eSIM doesn’t need to be swapped out — you simply scan a QR code to activate a mobile network.

With eSIM, users can register, activate, or switch carriers directly on the device, without visiting a store. This is the new SIM trend strongly supported by major brands like Apple, Samsung, Google, Xiaomi and global carriers.

2. Benefits of eSIM

Compared to a physical SIM, eSIM offers many outstanding advantages:

  • 🔹 No SIM swapping: Easily activated with just a QR code — no risk of damaging the SIM tray or losing the card.

  • 🔹 Multiple numbers on one device: A single phone can store multiple eSIMs — very convenient for frequent international travelers.

  • 🔹 Quick carrier switching: Just a few taps to switch plans or carriers.

  • 🔹 Convenient for international travel: No need to buy a physical SIM — simply buy eSIM online at Simglobal and scan the QR code when you arrive.

  • 🔹 Eco-friendly: Eliminates plastic waste from physical SIM cards.

3. How eSIM Works

eSIM is integrated into the device. When a user purchases an eSIM plan, the provider (such as Simglobal) sends a QR code containing network configuration data. You simply:

  1. Go to Settings → Mobile Data → Add eSIM

  2. Scan the QR code sent to your email

  3. eSIM automatically activates when you arrive at the destination country

The entire process takes only a few minutes — no physical SIM swap or computer connection required.

4. Does eSIM work on every phone?

Not all phones support eSIM. Popular devices that do include:

  • iPhone: iPhone XS, XR and newer

  • Samsung: Galaxy S20, S21, S22, Z Flip, Z Fold series…

  • Google Pixel: Pixel 3 and newer

  • Huawei, Xiaomi, Oppo, Vivo: Select premium models support eSIM
