설치 및 사용 가이드

eSIM을 설치하고, 도착 후 바로 접속하세요

QR 코드부터 연결 확인까지, 기기별로 단계대로 진행하세요.

Before you leave · Prepare and install

Connect to stable Wi-Fi, check when the plan starts, then install the eSIM.

After you arrive · Turn on and connect

Use the travel eSIM for data, turn on its roaming, then verify the connection.

When the plan starts counting is based on your order rules. Installing the eSIM does not always mean billing has started or that you are already online.

Before you start, confirm these 3 things

1. Your device supports eSIM and is not carrier-locked. Models can differ by sales region.
2. The phone is on stable Wi-Fi. Install on the phone that will use this plan.
3. You have the QR code or manual details from your order or email. Do not share them.

Is the QR code on this iPhone? (you may be able to add it in one tap)

02 Install the eSIM on iPhone

These steps use a QR code. Menu names may change with the OS version. Screenshots are in English — follow the highlighted spots.

On the Cellular screen, tap Add eSIM

Tap Continue and finish the system steps. iOS · actual menus may vary

03 Connect after you arrive

Make sure you are in a covered destination and the plan still has data and validity. “AirZlink Travel” means the travel eSIM you just installed.

1 Turn on this line

Settings → Cellular → AirZlink Travel → Turn On This Line.

Turn On This Line. iOS

2 Use it for data

Settings → Cellular → Cellular Data → choose AirZlink Travel.

Set Cellular Data to AirZlink Travel. iOS

3 Turn on data roaming

Open the AirZlink Travel settings and turn on Data Roaming.

Keep Data Roaming on for the travel line. iOS

Last step: turn off Wi-Fi and open a webpage

Wait for the phone to register on a local network, check for 4G / LTE / 5G, then open a webpage or map to confirm data works.

You can keep calls and SMS on your primary line. Confirm voice/SMS roaming fees with that carrier.

Connection check · turn off Wi-Fi, then open a webpage

04 Having trouble? Start here

The QR code won't scan / says it was already used

Check your network and that the QR code is clear, and confirm the eSIM is not already on the phone. Do not keep deleting and reinstalling. Contact support if it still fails.

It's installed, but I have no service

Confirm you are in a covered destination, the plan is valid, and data is not used up. Check the eSIM switch, data line, and roaming. Try airplane mode or a restart.

What should I enter for APN?

It is usually set automatically. Only fill it in if your order requires it or you cannot get data, using the values from the order or support. Do not guess APN, username, or password.

What if I don't need it yet / the trip is over?

You can turn off the travel eSIM and switch data back to your primary SIM. Do not delete an eSIM you still need. Turning the line off does not pause the plan validity.

Still not connected? We can help

Have your order number, device model, OS version, country/region, and a screenshot of the error ready.

Use official AirZlink support only. Do not share the full QR code or activation code in public.
