What Is an eSIM? (Figabytes Guide)

TL;DR: An eSIM is a digital SIM inside your phone. With Figabytes, you activate a plan by scanning a QR code or entering a code—no plastic card, no store visit, and you can keep multiple plans on one device.

What exactly is an eSIM?

An embedded SIM (eSIM) lives on a secure chip (eUICC) built into your phone, tablet, or wearable. Instead of inserting a card, you download a carrier profile—like a Figabytes plan—over the internet.

How it works in plain English

1. Your device has a secure eUICC chip.

2. Figabytes sends your eSIM profile (via QR/app/code).

3. Your phone installs and activates the profile, and you’re on the network—just like a normal SIM.

Why people switch to Figabytes eSIM

• Instant setup anywhere: Activate in minutes—perfect for last-minute trips.

• Two lines, one phone: Keep your primary number and add a Figabytes data plan for travel or work.

• Easy switching: Change plans without hunting for a shop or swapping tiny cards.

• Less plastic, more reliability: No removable parts; helps with water resistance and durability.

Things to know

• Device support: You’ll need an unlocked eSIM-compatible phone (iPhone XR or newer; most recent Samsung/Google/Xiaomi flagships).

• Wi-Fi required for install: Downloading the eSIM profile needs internet (usually Wi-Fi).

• One device at a time: Most eSIM profiles are single-use; deleting them may require a replacement.

Is your phone eSIM-ready?

Check Settings → About (look for “EID” or “eSIM”) or search your exact model’s specs. As a trend, recent devices are eSIM-first—and many support multiple stored profiles (some allow two active at once).

How to activate a Figabytes eSIM

Choose one of the three standard methods:

1. Scan a QR code

   • iPhone: Settings → Cellular/Mobile Data → Add eSIM → Use QR Code
