Vietnam eSIM FAQ
Does an eSIM work in Vietnam?
Yes. If your phone is eSIM-capable and carrier-unlocked, such as an iPhone XS or newer, or a recent Pixel, Samsung or other Android flagship, Vietnam's networks fully support eSIM data roaming. You install it from a QR code and nothing is posted to you.
How much data do I need for a week in Vietnam?
For maps, messaging, social and the odd photo upload, 3 to 5GB comfortably covers a week. If you stream video, video-call or share a hotspot, step up to a larger plan or an unlimited daily plan that refills every day.
Which networks does the Vietnam eSIM use?
It connects to Viettel Mobile, MobiFone and Vinaphone, so you get the strongest signal wherever you are.
Is an eSIM cheaper than a local SIM or pocket wifi in Vietnam?
Usually, yes. There is no counter to find, no deposit, no device to collect or return, and nothing extra to carry or charge. You also keep your own phone number reachable on your home SIM.
When should I install my Vietnam eSIM?
Install it at home on wifi before you fly. It stays dormant until it first connects to a network in Vietnam after you land, so your plan's validity only starts when you arrive.
Heading somewhere else?
One eSIM can cover a whole region, handy for multi-country trips.
Ready to land online in Vietnam?
Pick your data, install before you fly, connect the second you arrive.
