1. Pre-Installation Prerequisites: Device Check & Carrier Lock
Before purchasing an international data package on Airalo, you must verify two non-negotiable hardware and carrier requirements:
- eSIM Hardware Compatibility: Your device must possess an embedded eSIM chip. Compatible models include iPhone XS, XR, 11, 12, 13, 14, 15, and 16 series; Samsung Galaxy S20, S21, S22, S23, S24 series, Z Flip/Fold; Google Pixel 3 through 9 series. Verify by dialing *#06#: if an EID barcode appears on your screen, your device supports eSIM.
- Carrier-Unlocked Status: Your phone must not be network-locked by an international mobile operator (relevant if purchased on contract abroad). In iOS, check Settings -> General -> About -> Carrier Lock: it must display "No SIM restrictions". In India, virtually all retail smartphones are unlocked by default.
2. Step-by-Step Installation on iPhone (iOS)
The fastest and most foolproof installation method on iOS is Airalo's Direct Installation feature:
- Connect to Stable Wi-Fi in India: 1 to 2 days before departure, open the Airalo app connected to home Wi-Fi.
- Select My eSIMs: Tap your purchased package and select "Install eSIM -> Direct".
- Grant iOS System Permissions: Tap "Set Up Cellular" when prompted by iOS. The system initiates an automated handshake with Apple's activation servers.
- Label Your Cellular Plans: When prompted, label your physical SIM as "Primary" (or "Home") and label your new Airalo profile as "Travel" (or "Airalo").
- Set Line Allocations:
- Default Line (Calls/SMS): Select "Primary" (your Indian SIM).
- iMessage & FaceTime: Select "Primary".
- Cellular Data: Select "Primary" while still in India (you will switch to Travel upon landing).
- Allow Cellular Data Switching: Toggle OFF.
3. Step-by-Step Installation on Android (Samsung & Pixel)
Installing Airalo on Android devices follows a structured SIM Manager workflow:
- Open SIM Manager: On Samsung, navigate to Settings -> Connections -> SIM Manager. On Google Pixel, go to Settings -> Network & Internet -> SIMs.
- Add eSIM / Mobile Plan: Tap "Add eSIM" -> "Scan QR code".
- Scan QR Code or Direct Install: In the Airalo app, choose "Direct Install" or display the QR code on a second screen (laptop, tablet, or friend's phone) and scan it with your phone camera.
- Download Profile: Tap "Add" or "Confirm" to download the carrier profile. The profile will appear under your eSIM list as "Airalo" or the underlying network name (e.g. Orange, Singtel, Telekom).
- Keep eSIM Turned OFF in India: Leave the eSIM profile switched OFF until you land at your destination airport.
4. Landing Activation Protocol: What to Do at the Airport
The moment your aircraft lands at your international destination and decelerates along the runway, execute the 60-Second Landing Protocol:
- Turn Airplane Mode OFF.
- Go to Settings -> Cellular / Mobile Data.
- Switch Cellular Data from "Primary" to your "Travel" (Airalo) line.
- Tap on your Travel line and ensure Data Roaming is toggled ON.
- Wait 30 to 90 seconds while your device handshakes with the local roaming carrier (e.g., Vodafone UK, AIS Thailand, du UAE). An LTE/5G indicator will appear in your status bar!
5. Troubleshooting: APN Settings & 'No Service' Fixes
If your phone displays signal bars but data fails to load, resolve the issue in under 2 minutes with these proven fixes:
- Fix 1: Verify Data Roaming is ON: 80% of connection failures occur because travelers forget to turn Data Roaming ON for the eSIM line. Airalo functions as an international roaming MVNO; roaming MUST be active on the travel line.
- Fix 2: Configure the APN (Access Point Name): If data remains inactive, check your package instructions in the Airalo app under "APN". In iOS, go to Cellular -> Travel Line -> Cellular Data Network. In the APN field, type the exact APN provided (e.g.
globaldata,wbdata, orairalo). Leave username and password blank. - Fix 3: Toggle Airplane Mode or Restart: Toggle Airplane Mode on for 15 seconds to force the radio modem to re-scan for local cellular towers.
6. Data Conservation Hacks for 5GB & 10GB Plans
To ensure your 5GB or 10GB Airalo data package lasts throughout a 10 to 14-day international holiday, configure background bandwidth throttles before traveling:
- Enable Low Data Mode: In iOS, go to Settings -> Cellular -> Travel -> Low Data Mode and toggle it ON. This pauses automatic background app refresh, cloud photo syncs, and background system downloads. In Android, enable "Data Saver".
- Download Offline Google Maps: In India, open Google Maps, search your destination cities (e.g. Tokyo, Paris, Rome), and download offline map areas. GPS navigation functions completely offline without consuming a single megabyte of mobile data.
- Disable Social Media Auto-Play: Turn off automatic video playback in Instagram, YouTube, and X (Twitter) settings when on cellular connections.

Frequently Asked Questions
Can I install an Airalo eSIM before traveling to my destination?
YES. You should install the eSIM profile in India 1 to 2 days before departure using home Wi-Fi. The validity period only starts counting down when the eSIM connects to a supported foreign network upon landing.
Do I need to turn Data Roaming ON for Airalo to work?
YES. Data Roaming must be turned ON for the Airalo eSIM line for it to connect to partner cellular towers abroad. Keep Data Roaming OFF for your primary Indian SIM.
Does an Airalo eSIM provide a local phone number for calls?
Most standard Airalo packages are Data-Only, meaning they do not include a phone number or traditional calling. You make calls via WhatsApp, FaceTime, or Skype. Select Discover Global packs include international voice/SMS.
Can I top up my Airalo eSIM if I run out of data?
Yes. You can top up your existing eSIM directly through the Airalo app without installing a new profile. Simply select your active eSIM and choose a top-up package (e.g. 1GB, 3GB, 5GB).
What should I do if my Airalo eSIM shows 'No Service' abroad?
Ensure Data Roaming is turned ON for the eSIM line, verify that your Cellular Data is set to the eSIM, and check if manual APN entry is required under the package instructions in the Airalo app.
