Da Nang eSIM 2026 — Viettel vs Airalo comparison, guide to activating at the airport

4G/5G internet in Da Nang is very important for foreign visitors — for using Grab, Google Maps, Google Translate, and a VPN to stay in touch. In 2026, travelers have 2 main options: an eSIM from a Vietnamese carrier (Viettel/Vinaphone/Mobifone) or an international eSIM (Airalo, Nomad, Holafly). Prices differ by 2-5 times depending on the type.

Vietnamese carrier eSIM — Cheapest, with the best coverage. Viettel 7 days: 90,000 VND ≈ 3.5 USD, 10GB of high-speed 4G/5G data, then unlimited data at reduced speed. Vinaphone 7 days: 100,000 VND, 15GB high-speed data. Mobifone 7 days: 110,000 VND, 12GB high-speed data. Where to buy: carrier counters right in the arrivals hall at DAD airport (after baggage claim), and Viettel/Mobifone stores in the city center. Requirements: passport (registration is mandatory — new 2024 law).

International eSIM (Airalo/Nomad) — The most convenient option for travelers visiting multiple countries. Airalo 'Mun Vietnam' 7 days: 7-10 USD, 5-10GB. Buy online from abroad and activate it the moment you land — no need to go anywhere. Nomad Vietnam: 8-12 USD. Holafly: 19 USD (unlimited data, great for working). Advantages: you can buy it online in advance, fully in English/Japanese/Korean, and no passport is required. Cons: 2-3 times more expensive than Viettel, and it uses the Viettel/Mobifone network through an MVNO, so speeds are a bit slower.

Quick comparison — Which package should you choose? If you're staying in Vietnam for 5-10 days and know basic English → Viettel 90k (3.5 USD) — the most economical option. If you're only flying for 2-3 days and don't want any hassle → Airalo 7 USD — buy it online in advance, and it activates automatically. If you work remotely and use more than 20GB → Holafly unlimited 19 USD/week. If you're flying to multiple ASEAN countries → Airalo's regional 'Asialink' plan at 25 USD/30 days works in 10+ countries.

Guide to activating your eSIM at DAD airport: Step 1: Collect your luggage and head out to the arrivals hall. Step 2: Go to the Viettel/Vinaphone/Mobifone counter (on the left after you exit the gate). Step 3: Hand over your passport and choose a 7/15/30-day package. Step 4: The staff will give you a QR code and show you how to scan it. Step 5: In your phone's Settings → Add eSIM → Scan QR. Step 6: Wait 1-2 minutes for the connection, and you will receive a 'Welcome' SMS. Step 7: Test by opening Google Maps. Total time: 7-10 minutes.

Important note: (1) Check whether your phone supports eSIM before you travel — iPhone XS+, Pixel 3+, and Samsung S20+ are supported. Budget Android phones usually don't have it yet. (2) Unlock the SIM in your home country (if the phone is carrier-locked) — some Japanese/US iPhones are locked, so you need to ask your carrier to unlock it before you fly. (3) 5G coverage in Da Nang is good in the city center — but it's still 4G at Ba Na and My Son. (4) No roaming when you travel to Lang Co/Hoi An if you use an eSIM from a Vietnamese carrier (it works normally, with no extra charges). (5) Keep your original SIM installed — when you return home, you can use it right away without losing contact.
