Detailed A-Z Guide to Setting Up Airalo eSIM on iPhone

Airalo is the world's most popular eSIM travel provider. Setting up on iPhone takes only 3-5 minutes if you follow the steps below correctly. This article applies to iPhone XS and later, iOS 15+.

Step 1 — Buy Vietnam eSIM package: Download the Airalo app from App Store, create an account, find "Vietnam" in the country list. Choose a suitable package (usually 1GB/7 days for light check-in, 5GB/30 days for a 2-week trip). Payment via Apple Pay, Visa or PayPal. After payment, QR code will appear in the "My eSIMs" tab.

Step 2 — Activate the eSIM before your trip: Switch to another device (laptop, iPad) to display the QR code, since an iPhone cannot scan its own QR code. On iPhone: open Settings → Cellular → Add Cellular Plan → scan QR. Name the label "Vietnam Travel" for easy identification. If you don't have another device, you can manually enter the SM-DP+ address and Activation code (available in the Airalo guide).

Step 3 — Set up upon arrival in Vietnam: After the plane lands in Da Nang, open your iPhone: Settings → Cellular → Cellular Data → select "Vietnam Travel". Turn off "Roaming" for your main SIM to avoid international charges. Within 30-60 seconds, the signal icon and 4G will appear. Check by opening Safari or Google.

Step 4 — Track remaining data: Open the Airalo app, go to the "My eSIMs" tab → select the package you're currently using → check the remaining data. If it's about to run out, you can top up right in the app, no need to reactivate.

Important note: Do not delete eSIM while in use — if you delete it, it cannot be reused (you must purchase a new package). Keep your main Vietnam SIM active if you need to receive bank OTPs. Airalo Vietnam eSIM does not have a phone number to receive SMS, only data.
