Vietnam eSIM: a local guide
Who relies on it in Vietnam
Vietnam has a large community of foreign teachers, engineers, factory managers and remote workers, along with international students at universities in Hanoi and Ho Chi Minh City. For them, a year-long data eSIM is a tidy arrangement: one payment, a data line that sits alongside your home SIM, and a hotspot for the laptop in a café, a co-working space or a rented apartment while home broadband is sorted out.
Hanoi, Saigon and the coast between
Mobile data is used heavily in the cities. Hanoi, Ho Chi Minh City, Da Nang and Hai Phong are densely covered, and the coastal cities along the length of the country are well served. The industrial zones around Bac Ninh and Binh Duong, where many foreign staff work, are connected too, as are the main highways between them.
Mountains in the north, the delta in the south
Vietnam is long and narrow, and the land changes a lot from end to end. In the northern mountains around Sa Pa, signal follows the valleys and can drop on the high passes. The Central Highlands around Da Lat are covered in town but thinner across the coffee and tea country. In the Mekong Delta, towns such as Can Tho are well connected, while the smaller river channels and orchards between them can be patchier.
If your work takes you out to factories, farms or project sites in the provinces, expect good coverage in towns and the odd gap on the roads, and keep offline maps ready.

What our customers say
Feedback from expats, residents and remote workers using the same package.
“Three weeks from Ho Chi Minh up to Hanoi and it never dropped. Support answered every question fast.”
Ho Chi Minh City, Vietnam
“Non-PTA iPhone, installed in five minutes, and the 4G has been steady ever since. Hotspot for the laptop all day with no slowdown.”
Lahore, Pakistan
“A whole year of unlimited data for one payment is unbeatable. They confirmed my device on WhatsApp before I paid, which I appreciated.”
Karachi, Pakistan
“I was sceptical but it is exactly what they said. Good signal everywhere I have been, including on the motorway.”
Islamabad, Pakistan
“Really good value. Activation took closer to half an hour rather than ten minutes for me, but the team stayed on chat the whole time.”
Rawalpindi, Pakistan
“Met them in person, paid, and had it running before I left. Straightforward, and no paperwork at all.”
Faisalabad, Pakistan
One payment of $232 covers twelve months of unlimited data in Vietnam, about $19.33 a month. There is no monthly bill, no contract and no automatic renewal. Buying 10 or more in one order? The reseller rate is $58 per eSIM.
Yes. It covers the whole of Vietnam, not only Hanoi: the cities, the smaller towns and the roads between them, wherever our partner network has signal. As on any network, coverage is thinner in remote and sparsely populated areas. Tell us the town you have in mind and we will tell you what to expect there before you buy.
No. Each eSIM covers one country completely, and the Vietnam eSIM works only inside Vietnam. For Laos you need a Laos eSIM; a modern phone holds both profiles at once and switches between them in Settings.
Yes. Hotspot is included and not metered separately, so you can run a laptop, a tablet or a TV from your phone anywhere in Vietnam. Tethered data is treated like any other data, under the network operator's Fair Usage Policy.
One package: a 12-month unlimited-data eSIM for the country you choose. It covers the whole country, not just the big cities, with unrestricted hotspot use, and takes about five minutes to set up. We supply eSIMs for 200 countries; pricing in some of them varies with local network conditions, and we confirm the exact price before you buy.
In very rare cases the connection may appear to pause. The fix is instant: turn OFF mobile data, wait 5 seconds, then turn ON mobile data again. This resolves it almost every time.
Datainfinite is an independent eSIM reseller. We do not own a mobile network: we buy data wholesale from licensed B2B carriers such as Telnyx, 1GLOBAL, Telna and BICS, choose the best route for each country, and handle setup and 24/7 support ourselves. Your eSIM runs on local partner networks in the country you choose.
Try the following, in order:
- Turn Airplane Mode ON, wait 10 seconds, then OFF
- Restart your device once
- Make sure Data Roaming is enabled
- If it persists, contact our support team, we are here 24/7
Your phone needs to support eSIM and must not be carrier-locked or JV (Joint Venture) restricted — a JV handset is SIM-locked to a specific foreign carrier under contract. Most iPhones from the XS onward, recent Samsung Galaxy and Google Pixel models qualify, send us your device model on WhatsApp and we will confirm before you buy.
Message us on WhatsApp or email us. We confirm your device is compatible, confirm the price for your country, and send your eSIM QR code straight to you, all we need are your contact details.
No. Each eSIM is for one country and covers all of it: the cities and towns across that country, wherever our partner network has signal. If you need a second country, that is a second eSIM. Tell us where you are going and we will set up the right one.
No. The eSIM sits alongside your existing SIM and carries data only, so calls and texts keep arriving on your normal number. You simply set Datainfinite as the default data line.
Your eSIM may not work in China due to several factors. Check if your device is compatible with local networks, ensure that the eSIM is activated correctly, and verify that you have a valid data plan. Additionally, confirm that airplane mode is off and that network settings are properly configured.
Handsets bought in mainland China or Hong Kong are the usual cause: those models ship with dual physical SIM and no eSIM hardware at all. Send us your exact model on WhatsApp and we will confirm before you buy.
