Question 1

What is the Airalo 'Xin Chao' plan?

Accepted Answer

Xin Chao is simply Airalo's brand name for its Vietnam eSIM — 'xin chào' is Vietnamese for hello, and Airalo names each country pack after a local greeting. It is not a different product or a special tier. If you searched for a 'Xin Chao 3GB 30 days' price, you are looking for Airalo's standard 3 GB / 30-day Vietnam plan, which you will find in the comparison table above alongside the equivalent bundle from every other provider.

Question 2

How much is a 3 GB, 30-day eSIM for Vietnam?

Accepted Answer

This is the single most-requested Vietnam bundle and most providers price it in a narrow band. Because Vietnamese wholesale data is cheap, the gap between the most and least expensive 3 GB / 30-day plan is usually small in absolute terms — check the live table above for today's figures, since promotional pricing moves month to month.

Question 3

Which eSIM is cheapest for Vietnam?

Accepted Answer

It depends on bundle size rather than brand. Budget-focused providers typically win on small starter bundles, while the mid-size 5–10 GB range is where the larger brands compete hardest on cost per gigabyte. Sort the table above by price or by cost per GB — the winner genuinely changes depending on which you optimise for.

Question 4

Does an eSIM work everywhere in Vietnam?

Accepted Answer

Coverage is strong in cities, along the coastal corridor and on the main highways, since travel eSIMs roam on Viettel, Vinaphone or MobiFone — the same networks locals use. Expect gaps in the far northern mountains around Ha Giang and Sa Pa, and on boat trips in Ha Long Bay. Download offline maps before those legs regardless of which provider you pick.

Question 5

How much does an eSIM for Vietnam cost?

Accepted Answer

Vietnam eSIM plans vary by provider and data amount. Plans typically start from $2-5 for 1 GB with pay-as-you-go providers. Standard plans with 3-5 GB for a week or two typically range from $8 to $15. Compare prices above to find the best deal.

Question 6

Can I keep my WhatsApp number while using an eSIM in Vietnam?

Accepted Answer

Yes! Your WhatsApp number is tied to your original phone number, not your data plan. When you add a travel eSIM for Vietnam, WhatsApp continues to work with your existing number. Just make sure to set the eSIM as your data line while keeping your original SIM for calls/SMS.

Question 7

When should I install my Vietnam eSIM?

Accepted Answer

We recommend installing your eSIM before departure (you can do this via QR code at home) but only activating it once you arrive in Vietnam. Most plans start their validity period upon first connection to a local network.

Question 8

Is my phone compatible with eSIM?

Accepted Answer

Most phones released after 2020 support eSIM, including iPhone XS and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer, and many other Android devices. Check your phone settings for an 'Add eSIM' or 'Add Cellular Plan' option.

Question 9

What network coverage will I get in Vietnam?

Accepted Answer

Coverage depends on the provider and their local network partners. Most eSIM providers offer 4G LTE coverage in Vietnam, with 5G available in select areas. Check the provider details above for specific network information.

Trip type	Suggested plan	Why
City break, 5–7 days	1–3 GB	Cafés, hotels and even street-food places in Hanoi and Ho Chi Minh City almost all have free wifi. Data mostly covers maps and ride-hailing between stops.
Two-week trip, north to south	3–5 GB	The common choice. Grab (ride-hailing) and offline-capable maps are the main drains; long train and sleeper-bus legs have patchy coverage anyway.
Remote work / month-long stay	10–20 GB or unlimited	Vietnam is a major digital-nomad base. At this length a 30-day plan is far better value than stacking short ones.
