越南 eSIM

An eSIM is a SIM built into your phone, tablet or smartwatch. It connects you to a mobile network without a physical SIM card.

Check if your device supports eSIM.

An eSIM is 100% digital: there is no card to insert. You install it by scanning the QR code from your order email, or in one tap from the eSIM Prime app. Your main SIM stays in your phone, and you switch to your eSIM Prime data plan when you land in 越南.

Your eSIM Prime plan lets your phone connect directly to local mobile networks in 越南. There is no physical SIM to handle, and you keep your usual number for calls and texts.

• Practical: buy your eSIM before you leave or once you arrive.
• Flexible: manage your plans and top up in a few taps in the eSIM Prime app.
• Economical: no more expensive roaming charges abroad.
• Online on arrival: install it in a few clicks and connect as soon as you land.
• No physical SIM: a digital, stress-free solution.
• Fast network: 4G/5G on reliable local networks across 越南.

Choose an eSIM that is reliable, affordable and simple to install. eSIM Prime connects you to reliable local networks in 越南, with 4G/5G where available, no contract and no physical SIM.

The best plan is the one that covers your data needs at a fair price, installs quickly and comes with real help if something goes wrong.

With eSIM Prime, data starts from $1.40 per GB, with no subscription and no hidden fees. You install it with the QR code from your email or directly in the eSIM Prime app, and our support team is available 24/7.

Check these four points before you buy:

1. Data volume: it should match your use (maps, social media, video).
2. Plan duration: it should cover your whole stay.
3. Network quality: a stable connection across 越南, not only in big cities.
4. Price per GB.

The price depends on the amount of data and the length of your stay. eSIM Prime plans for 越南 start at $1.99 and go up to $27.99, from $1.40 per GB, with no hidden fees and no subscription.

eSIM Prime connects to the best available local network in 越南 and switches automatically to the fastest one, including 5G where available. You get a stable connection in cities and popular areas. As with any operator, coverage can be weaker in very remote places.

Our customers rate eSIM Prime 4.6 out of 5. Travelers most often mention a quick connection on arrival, helpful support and good value for money.

Your usual plan can charge high roaming fees as soon as you leave your country. With an eSIM Prime plan, you pay a fixed price upfront, with no surprise bills, and you are online as soon as you land.

eSIM Prime installs from home, with no extra device and no airport counter, and you can still share your data with hotspot.

A pocket Wi-Fi can connect several devices, but it usually costs more and must be returned after your trip.

A local SIM has to be bought on site, often with an ID, and takes the place of your usual SIM while it is in your phone.

Most smartphones released since 2019 support eSIM. Your phone must also be carrier-unlocked.

Check your device in a few seconds.

There are very few: not every phone supports eSIM yet, and an eSIM cannot be moved to another device once it is installed. With eSIM Prime, installation only takes a few minutes.

No. An eSIM is linked to the device it was installed on. To use an eSIM on another phone, buy a new one for that device.

You can buy it at any time, but we recommend doing it at home before you leave. You can install it calmly, check that your phone is compatible and be online as soon as you land, without looking for a shop at the airport.

The validity of your plan starts when the eSIM is installed and activated, not on the day you buy it.

Install your eSIM before you leave, while connected to the internet (Wi-Fi or mobile data). When you arrive in 越南, turn on data roaming for the eSIM in your phone settings and start browsing right away.

No. With eSIM Prime you get normal mobile internet: WhatsApp, Google Maps, Instagram, TikTok and your banking apps work as they do at home.

Yes. Hotspot is included: turn on personal hotspot on your phone to share your eSIM data with your laptop or other devices.

Your connection simply stops, with no automatic extra charges. You can top up in a few taps in the eSIM Prime app, with no need to install a new eSIM. Your new data is available right away.

Yes. Keep the eSIM on your phone: when you need more data, top it up from the eSIM Prime app without reinstalling anything.
