Best eSIM for Vietnam in 2026
Our value pick for Vietnam is eSimania, about $2.85 for 1 GB or $11.61 for a 30-day 5 GB plan, under Airalo (about $4 and $14). Jetpac is the budget option from about $1 for a wider Asia trip. For a week, 3 to 5 GB is plenty, and Viettel, Vinaphone and Mobifone cover the cities and main sights well. Prices verified July 8, 2026; speeds are carrier-dependent and never guaranteed.
Vietnam is a good place to use a travel eSIM: cheap data, solid city coverage, and no need to queue for an airport SIM. Install from a QR code before you fly and you land in Hanoi or Ho Chi Minh City already online. Below are the plans we route to, a price check and how to size your data.

How much data you need in Vietnam
Coverage: which network
Viettel has the widest reach in Vietnam, including rural and mountainous regions, with Vinaphone and Mobifone strong in the cities. Hanoi, Ho Chi Minh City, Da Nang and the main beaches are well served on any network; remote highlands and small islands can be weaker. Because eSimania is a marketplace it does not name the exact network, so for off-the-beaten-track trips check the plan or favour one on Viettel.
Frequently asked questions
How much eSIM data do I need for Vietnam?
For a week, 3 to 5 GB covers maps, ride apps, messaging and photos. Resort stays leaning on wifi can manage with 1 to 2 GB, while heavy streaming or tethering a laptop needs a larger plan. Longer trips through several cities may want 10 GB.
Will an eSIM work in Vietnam?
Yes, if your phone is eSIM-capable and carrier-unlocked. Vietnam has good 4G and growing 5G through Viettel, Vinaphone and Mobifone, strong in cities and main tourist areas. Install the eSIM from its QR code before you fly and enable it on arrival; remote areas can be weaker.
Which network is best in Vietnam?
Viettel has the widest coverage, including rural and mountainous areas, with Vinaphone and Mobifone strong in cities. For trips beyond the main hubs, favour a plan known to use Viettel; in Hanoi, Ho Chi Minh City and Da Nang any of the three works well.
Is an eSIM better than an airport SIM in Vietnam?
An eSIM is usually simpler: you arrive already connected instead of queuing, and you keep your home number. Airport and shop SIMs in Vietnam are cheap and offer big data bundles, but an eSIM bought in advance saves time and is easy to compare on price before you fly.
