Before You Start: What You Need

• A compatible unlocked phone: iPhone XS or newer (iOS 12.1+), Google Pixel 3+, Samsung Galaxy S20+, or most recent Android flagships.
• A MyLine eSIM plan purchased (QR code sent via email or in the MyLine app).
• Stable Wi-Fi (for initial setup — you can activate before travel).
• Your phone’s IMEI (dial *#06# or check Settings → About Phone).

How to Install a MyLine eSIM on iPhone

1. Open the email or MyLine app containing your QR code.
2. Go to Settings → Cellular (or Mobile Data).
3. Tap Add eSIM (or Add Cellular Plan).
4. Choose Use QR Code and scan the MyLine QR code from your email/app (or another device screen).
5. Wait for activation — your phone will download the profile (takes 10–60 seconds).
6. Label the plan (e.g., “MyLine Europe 10GB”) and choose which line uses data, calls, texts.
7. Enable Data Roaming on the MyLine line when you arrive (Settings → Cellular → MyLine → Data Roaming ON).

Tip: Keep your primary SIM/eSIM for calls/texts (2FA, banking). Set MyLine as default data line: Settings → Cellular → Cellular Data → MyLine.

How to Install a MyLine eSIM on Android

Steps vary slightly by manufacturer (Samsung, Google Pixel, etc.), but general process:

1. Open Settings → Network & internet → SIMs (or Mobile network → SIM manager).
2. Tap Add eSIM / Download a SIM instead?.
3. Choose Scan QR code or Enter activation code.
4. Scan the MyLine QR code from email/app.
5. Wait for download & activation (10–60 seconds).
6. Name the eSIM (e.g., “MyLine Asia”) and set it as preferred for mobile data.
7. Enable Data Roaming when you arrive (Settings → Network & internet → SIMs → MyLine → Roaming ON).

Samsung-specific: Settings → Connections → SIM card manager → Add mobile plan → Scan QR code.

Pixel-specific: Settings → Network & internet → SIMs → + Download a SIM instead?

Using MyLine eSIM + Your Home Number (Dual SIM Setup)

Most modern phones support Dual SIM Dual Standby (DSDS):

• iPhone: Set MyLine for data, home line for calls/texts (or vice versa). Both lines active — receive calls on home number while using MyLine data.
• Android: Choose default data SIM (MyLine), default call/text SIM (home). Enable “Mobile data during calls” if needed.

Best practice: Keep home number for 2FA, banking alerts, family calls. Use MyLine for all data (maps, rideshares, browsing, streaming). Use WhatsApp/WeChat/Signal for voice/video over data — free and high quality.

Common Troubleshooting & Tips

• QR code not scanning: Enter activation code manually (in email/app) or try on Wi-Fi.
• No service after landing: Enable Data Roaming, restart phone, select network manually (Settings → Cellular → Network Selection).
• Activation error: Check IMEI compatibility in MyLine account, ensure phone unlocked, try again on Wi-Fi.
• Hotspot not working: Turn on Personal Hotspot in settings — most MyLine plans support it.
• Running out of data: Check usage in MyLine app, top up instantly (no Wi-Fi needed if you have some data left).
