If you’re not using a Figabytes eSIM when you travel, you’re getting ripped off.

In short: An eSIM is a digital version of a SIM that lives on a secure chip inside your phone. Instead of inserting plastic, you download a mobile plan (a “profile”) and switch lines in your settings—perfect for travel, side lines, or testing better coverage.

The moving parts (minus the jargon)

• Your phone’s eUICC chip: A tiny secure element that stores one or more eSIM profiles.

• The profile: The digital equivalent of a SIM card (your number/plan/network settings).

• Remote download: Figabytes sends the profile via QR/app/code over the internet.

• Activation: Your phone validates the profile and registers on the network—done.

Think of it like installing a ticket into a digital wallet: once added, your phone shows the right “pass” at the network gate to get you connected.

Why people use Figabytes eSIM

• Zero plastic, no shop runs: Activate from the couch or at the airport gate.

• Dual lines on one phone: Keep your main number and add a Figabytes data plan for travel or work.

• Faster carrier switching: Try plans without waiting for delivery or hunting for kiosks.

• Travel superpower: Land, toggle Data Roaming on the Figabytes line, and go online in minutes.

What you need to make it work

• An unlocked, eSIM-capable phone (iPhone XR+; recent Samsung, Google, Xiaomi, etc.).

• Wi-Fi for the install (the download step).

• Your Figabytes details: QR code or manual SM-DP+ and Activation Code (sometimes a confirmation code).

How activation feels in real life

1. Buy a Figabytes plan → receive your QR or codes.

2. Install over Wi-Fi:

   • iPhone: Settings → Cellular/Mobile Data → Add eSIM → Use QR Code (or Enter Details Manually).

   • Samsung: Settings → Connections → SIM Manager → Add eSIM → Scan QR.

   • Pixel: Settings → Network & Internet → SIMs → Add SIM → Download a SIM → Scan QR.

3. Set Mobile Data to the Figabytes line.

4. Turn on Data Roaming when abroad.

5. If data doesn’t start, add the APN from your Figabytes order, then toggle Airplane Mode off/on.

Dual SIM basics

Most modern phones let you store multiple eSIM profiles and keep at least one active alongside a physical SIM (newer phones can run two eSIMs at once). You can label lines (e.g., “Personal” and “Figabytes Travel”) and choose which handles Data, Calls, and iMessage/FaceTime (iOS) or Calls/SMS/Data (Android).

Security & peace of mind

• Harder to tamper with: There’s no tiny card to yank or clone.

• Remote control: You can add/remove profiles digitally (subject to plan rules).

• Same phone protections: PIN/Face/Touch ID still guard your device and settings.

Common questions

Does WhatsApp change when I add an eSIM?
No. WhatsApp keeps your current number unless you change it inside the app.

Can I move my eSIM to a new phone?
Often yes—with eSIM transfer tools on iOS/Android or by issuing a fresh Figabytes QR. Delete the old profile only after the new one works.

What if I can’t scan the QR?
Increase screen brightness or print it. If it’s expired/used, request a new QR from your Figabytes account.

Quick troubleshooting

• “Activation failed” or no signal: Use Wi-Fi for install, restart the phone, toggle Airplane Mode, ensure Data Roaming is on for travel plans.

• No data after install: Set Mobile Data to Figabytes, add the APN, turn off any VPN, reboot.

• “eSIM already in use”: Most profiles are single-use. Ask support for a replacement profile.

Bottom line

eSIM turns mobile service into software: download, switch, and travel without plastic. With Figabytes, you get quick setup, flexible plans, and simple controls right from your settings—ideal for frequent flyers, remote workers, and anyone chasing better value.
