Installing a Taiwan eSIM takes about two minutes, and the golden rule is simple: install before you fly, activate when you land. This guide walks through the exact steps for both iPhone and Android, plus how to fix the most common issues.
Before you start
- Check your phone supports eSIM and is carrier-unlocked (dial *#06# and look for an EID).
- Be on a stable wifi connection.
- Have your eSIM QR code ready (on another screen, or printed).
How to install a Taiwan eSIM on iPhone
- Go to Settings, then Mobile Service (or Cellular), then Add eSIM.
- Choose Use QR Code and scan your eSIM QR code.
- Label the plan, for example “Taiwan”, and keep your home line as primary for now.
- Leave “Turn On This Line” off until you land, so it does not activate early.
- When you arrive in Taiwan, enable the Taiwan line and turn on Data Roaming for it.
How to install a Taiwan eSIM on Android
Steps vary slightly by brand, but the flow is the same:
- Go to Settings, then Network and Internet (or Connections), then SIMs or Mobile Network.
- Tap Add eSIM or Download a SIM instead, then scan your QR code.
- Finish setup but do not set it as active data until you land.
- On arrival in Taiwan, switch mobile data to the Taiwan eSIM and enable roaming.
What to do when you land
Turn off airplane mode, enable data roaming for the Taiwan eSIM, and open maps to confirm you are connected. It usually takes under a minute.

Frequently asked questions
Will installing an eSIM remove my normal SIM?
No. Your original line stays. The eSIM is an additional line you can turn on and off.
Can I install it at the airport?
Yes, on airport wifi, but installing before you fly is smoother. See Can I use eSIM at Taiwan airport?
