Our unlimited plans run on the same VNPT network Airalo uses, with no daily cap and no throttling — from $5.90 for 3 days. They are data-only, with no +84 number, and each one runs on a line reserved for a single traveller, so stock is limited.

Vietnam's #1 carrier — best 4G/5G coverage including remote provinces. Recommended for travelers heading off the beaten path.
State-owned carrier with strong urban coverage. Our Vinaphone 5GB/day plans are the only plans with a Vietnamese number: they receive incoming calls and ordinary SMS (Grab and hotel callbacks). App and bank verification codes do not arrive, and outgoing calls are not included. Vinaphone Unlimited plans are data only, with no number.
Best value per gigabyte — 7GB/day plans for heavy data users. Strong coverage in cities and major tourist areas.
All eSIMs on this site are tourist eSIMs. The daily allowance runs at full carrier speed and then stops until midnight Vietnam time — it is never slowed to a crawl. When the validity period ends the eSIM is switched off automatically and cannot be extended: buy another plan if you need more days.
Only our Vinaphone 5GB/day plans come with a Vietnamese phone number that receives incoming calls and SMS (so Grab drivers, hotels and restaurants can reach you). It does not receive app or bank verification codes (OTP), so keep your home SIM active for those. Outgoing calls are not included on any plan. Vinaphone Unlimited, Viettel and Skyfi plans are data only (no number).
5GB a day is a lot for a traveller: maps, messaging, social, music and several hours of video all fit inside it, and it refills every morning instead of draining one fixed bucket — a 15-day Viettel plan is 75GB in total. The important difference is speed. Most “unlimited” travel eSIMs give you 0.5–2GB per day at full speed and then throttle to roughly 128 kbps–1 Mbps for the rest of the day (the throttle figures are listed publicly on esimdb.com/vietnam; Holafly words it as a “Fair Usage Policy”). At that speed maps, video calls and ride-hailing apps barely work. Our plans have no throttled tier: the whole daily allowance runs at the carrier's normal 4G/5G speed. Our own Unlimited plans are the exception: they are on Vinaphone and have no daily cap and no throttled tier at all — see Unlimited Vietnam eSIM.
If you have an iPhone XS or newer, Pixel 3 or newer, Samsung Galaxy S20 or newer, or any flagship Android released after 2020, you almost certainly have eSIM support. iPhones sold in mainland China, Hong Kong, and Macau before 2024 do NOT support eSIM — buy a physical SIM elsewhere if your iPhone was bought in those regions. Always confirm at Settings → Cellular → Add eSIM (iOS) or Settings → Connections → SIM manager → Add (Android).
An eSIM (embedded SIM) is a digital SIM that lives in your phone's hardware. You activate it by scanning a QR code instead of inserting a plastic card. Since 2018, most flagship phones (iPhone XS, Pixel 3, Galaxy S20 and later) support eSIM, and many can run an eSIM and a physical SIM at the same time (dual SIM).
Daily plans: You receive your eSIM QR code by email within 60 seconds of payment confirmation. The eSIM itself activates the moment your phone connects to a Vietnamese mobile network — usually within 1-2 minutes of landing and turning on cellular data. Your Unlimited eSIM QR is emailed before your chosen start date. Your plan starts on the start date you pick and you get the full number of days. Daily plans: the QR is emailed instantly after payment. Your Unlimited eSIM QR is emailed before your chosen start date. Your plan starts on the start date you pick and you get the full number of days. The airport physical-SIM pickup QR is emailed before 12:00 Vietnam time (GMT+7) on the day before you land.
Full refund within 7 days of purchase if the QR code has not been activated on a phone. Once the QR is activated, the eSIM is provisioned to your device and cannot be refunded. Contact admin@telebox.vn with your order number to request a refund before activation.
