Buy a Vietnam eSIM: 4G internet in Hanoi, Da Nang, Hoi An and Ho Chi Minh City without steep roaming rates. QR activation in 30 seconds.
Vietnam sits far outside European and US home zones. A local data package works from landing — no airport SIM queue.
Your home SIM stays active on dual SIM: calls and banking SMS keep working as usual.
Internet in Vietnam: networks and speeds
Vietnamese networks (Viettel, Vinaphone, Mobifone) run surprisingly good LTE — typically 20–80 Mbps, with Viettel covering rural areas too. 5G is rolling out in the biggest cities. The eSIM connects to the strongest partner network automatically, so you never compare operators at the airport.
Coverage on the north–south route
Hanoi, Ha Long Bay, Ninh Binh, Hue, Da Nang, Hoi An, Nha Trang, Ho Chi Minh City and Phu Quoc island — stable LTE. On Ha Long cruises signal works near shore. In the northern mountains (Sapa, the Ha Giang Loop) internet lives in towns and along roads, but drops on the passes — download offline maps for the motorbike loop.
Why an eSIM beats roaming in Vietnam
Vietnam is outside every European home zone: operators charge high per-MB rates or costly day passes. A local data package via eSIM costs a fraction of that, and the profile is installed before you even fly — no passport registration at a SIM shop and no risk of fake street-stall SIMs.
Guides and help
Why an eSIM for Vietnam
Grab instead of haggling with taxis, a translator for street food, scooter navigation, train tickets online — in Vietnam the internet is a traveller's basic tool. It works from minute one, and hotspot at no extra charge covers a digital nomad's laptop.
Two weeks usually fit in 10 GB; for a month of remote work choose a bigger package or Unlimited. Continuing to Thailand, Cambodia or Singapore? Check the regional Asia eSIMs — one profile for the whole route.
Vietnam eSIM — frequently asked questions
Do I need to register with my passport?
No — our profiles work in travel mode, so the paperwork required for local SIM cards does not apply.
What is coverage like on the Ha Giang Loop and in Sapa?
Internet works in towns and along main roads; it drops on passes and remote stretches. Download offline maps before heading into the mountains.
When should I activate the eSIM?
Install the profile at home on Wi-Fi and switch data on after landing. Validity starts with the first network connection.
Does hotspot / tethering work?
Yes, at no extra charge — share the internet with a laptop or travel companions.
Do I keep my home number for calls and banking SMS?
Yes. Dual SIM: data through the eSIM, calls and SMS — including bank codes — on your home number. Keep data roaming off on your home SIM.
Key takeaways
How Unlimited data speed works
Unlimited plans give you the full-speed data shown on the card. After you use that allowance, data keeps working at a reduced speed until the end of the UTC day. Example: 500MB / 1 Day Unlimited - 512 Kbps = 500MB at full speed, then 512 Kbps until 00:00 UTC.
180 Days to Activate
Purchase your eSIM now and activate it anytime within 180 days from the date of purchase. Just install the eSIM and connect to the mobile network in your destination country to enjoy uninterrupted internet access!
