Vietnam Internet Q&A

Q1：Is it cheaper to buy a SIM card locally in Vietnam?

Buying a SIM card in Vietnam can sometimes be slightly cheaper than buying one abroad.
However, the price difference is usually minimal, and you'll spend time queuing and searching for a shop.
Language barriers may also make it tricky to choose the right plan, and there's a risk of being overcharged.
We recommend purchasing your SIM or eSIM before your trip.
While it may cost a little more, you gain convenience and peace of mind—having internet ready as soon as you land lets you book a ride, check maps, and avoid the stress of navigating an unfamiliar airport. The time and effort saved are usually worth more than the small amount of money you might save locally.

Q2：Which phones support eSIM?

The convenience of eSIM is attracting more travelers, but not all phones support it.
Currently, eSIM is compatible with most recent iPhones and some high-end Android models:
•iPhone： Generally, iPhone XR/XS and later models support eSIM.
•Android： Examples include Samsung S20 series, Google Pixel 3 series, and some other flagship phones.
Before purchasing, always check online if your phone model supports eSIM to avoid buying a plan you can't use.

Q3：What if I run out of data?

If your plan isn't unlimited or you exceed the high-speed data limit, there are usually a few options:
•Purchase extra data: Most providers allow you to top up data via their website, app, or in-store.
•Reduced speed: Some plans offer "throttled unlimited" service—once the high-speed limit is reached, your internet speed slows down. You can still send messages and use maps, but browsing may feel slower.
•Buy a new plan: If your SIM/eSIM cannot be topped up, you may need to purchase a new card.
Tip: Before buying, consider your internet usage habits. If you plan to stream videos or upload many photos, an unlimited or high-capacity plan is recommended to avoid running out of data mid-trip.

Conclusion: Which Option Works Best?

Solo short trips: eSIM is easiest.
Long-term stay: Physical SIM gives the best value.
Family or group trips: WiFi router is cost-efficient
