Trip.com Asia eSIM Reviews – What Real Travelers Say
Does Your Phone Support Asia eSIM?

Method 1: The Quickest Check (Universal)
- Open the Phone or Dialer app on your device.
- Dial: *#06#
- Your screen will display your phone's unique identification numbers.
- What to look for:
- If you see an EID (Embedded Identity Document) number, your phone definitely supports eSIM.
- If you only see an IMEI number (and no EID), your phone likely only supports a physical SIM card.
The presence of an EID is the best indicator of eSIM support.
Method 2: Check Your Phone's Settings
You can also find this information in your settings menu. The path varies by operating system.
For iPhones (iOS):
- Go to Settings > General > About.
- Scroll down. If you see "Digital SIM" or "EID", your iPhone supports eSIM.
- Supported Models: All iPhone XS, XR, 11, 12, 13, 14, 15 series and newer. (iPhone 14 and 15 models in the US are eSIM-only).
For Android Phones:
- Go to Settings > About Phone.
- Look for "SIM Status" or "IMEI Information". You should see an entry for EID if eSIM is supported.
- Supported Models: Many Google Pixel (3 and newer), Samsung Galaxy (S20 series and newer, Z Fold/Flip series), and other flagship models from various brands. Support is now common in mid-range models as well.
How to Set Up Asia eSIM on iPhone & Android
Step 1: Start the Installation
- Go to Settings > Cellular.
- Tap "Add Cellular Plan".
Step 2: Scan the QR Code
- Use your iPhone's camera to scan the QR code provided by Trip.com.
- A prompt will appear at the top of the screen saying "Cellular Plan Detected." Tap it.
Alternative: If you saved the QR code as an image, go to Settings > Cellular > Add Cellular Plan > Use QR Code from Photo Library.
Step 3: Configure the eSIM
You will see a screen to set up your cellular plan. It's crucial to configure these settings correctly:
- Label: Rename it to something clear, like "Asia Data" or "Trip.com eSIM".
- Default Line: For Cellular Data, select your NEW Asia eSIM. This tells your phone to use the eSIM for internet browsing.
- Turn On This Line: Make sure this is switched on.
Step 4: Activate and Enable Data Roaming
- Follow the on-screen prompts to complete the installation.
- After installation, go back to Settings > Cellular > [Your Asia eSIM].
- Turn ON "Data Roaming". This is essential for the eSIM to connect to local networks abroad.
Step 5: Using the eSIM (When You Arrive)
- Once you land in Asia, your iPhone should automatically connect to a local network using the eSIM.
- To ensure it's working, you can temporarily turn off your primary line (Settings > Cellular > [Your Primary Line] > Turn On This Line -> Off). This forces the phone to use only the eSIM.
