Vietnam eSIM: Stay Connected in 5 Minutes

Yes. AVIA partners with GIGAGO, a Vietnamese eSIM provider, to supply every plan on this page. When you tap Book Now or Get My eSIM Now, you are taken to AVIA’s GIGAGO-powered booking page, where AVIA travelers get 10% off automatically. The eSIM is provided by GIGAGO; AVIA remains your point of contact and our team supports you 24/7 on WhatsApp before, during, and after your trip.

A Vietnam eSIM is a digital SIM card that works through your phone’s built-in eSIM chip — no physical card needed. After purchase, you receive a QR code by email. Scan it once, and your data plan activates automatically. Your existing home SIM stays active at the same time, so you keep your regular number for calls and OTPs while using local Vietnamese data for browsing, maps, and messaging.

Yes, absolutely. With an eSIM, you don’t need to waste time searching for a SIM kiosk or waiting in long lines after a long flight. You can install it before your trip, and the moment your plane touches down in Vietnam, simply turn on your data line to get connected immediately — no physical SIM swapping or airport hassle required.

You can buy at any time — even weeks before your trip. However, for most plans, the validity countdown starts the moment you install the eSIM on your phone, not when you purchase it. Our recommendation: buy in advance, but install the eSIM right before boarding your flight to Vietnam. That way, you arrive connected without burning any plan days while still at home.

After payment, your QR code arrives by email within 5 minutes. To install:

• iPhone: Settings → Cellular → Add eSIM → Use QR Code → scan
• Android: Settings → Connections → SIM Manager → Add eSIM → scan

Once scanned, the eSIM installs in under a minute. Important: the QR code is single-use — do not delete the eSIM once installed, as it cannot be re-scanned.

Unfortunately, eSIM QR codes are single-use. Once you delete the eSIM profile from your phone settings, the plan is lost and the original QR code cannot be reinstalled. If you encounter any issue, stop and contact AVIA support immediately via WhatsApp before removing anything from your phone settings. Our team is available 24/7 and can advise on next steps.

Most modern smartphones support eSIM. Confirmed compatible devices include iPhone XR and newer (including all iPhone 15 and 16 models), Samsung Galaxy S20 and newer, Google Pixel 3 and newer, and many recent Huawei, OnePlus, and Motorola models. The only requirement: your phone must be carrier-unlocked. Not sure? You can also chat with us on WhatsApp for a quick confirmation.

It depends on your trip length and data needs. Choose Viettel if you’re traveling to rural areas, northern mountains (Sapa, Ha Giang), or need to share your connection via hotspot — Viettel has the widest nationwide coverage and supports tethering. Plans start from $9.81 for 7 days with 5GB/day. Choose Wintel Unlimited if you’re staying in cities and towns and want truly unlimited data without worrying about caps — ideal for streaming, video calls, and remote work. Wintel is single-device only (no hotspot). Plans start from $14.31 for 10 days.

Yes. The Viettel eSIM supports hotspot and tethering, so you can share your connection with a laptop or another device. The Wintel Unlimited eSIM is designed for single-device use only and does not support hotspot. If sharing data matters to you, choose the Viettel eSIM.

No. Both the Viettel eSIM and the Wintel Unlimited eSIM are data-only and do not include a local Vietnamese phone number. For calls, use an app like WhatsApp, Zalo, or FaceTime over your data connection.

Yes. Your physical SIM stays fully active in your phone’s SIM slot. You’ll run two lines simultaneously — your home number for incoming calls, OTPs, and banking apps, and your Vietnam eSIM for local data. You will not lose access to your regular number at any point during your trip.
