Vietnam SIM & eSIM cost · 2026
Pay for the data you need — not the biggest number on the package
A cheap SIM is not useful if the validity, registration or device compatibility does not fit your trip. VOAB uses current official carrier benchmarks and keeps local SIM/eSIM products separate from international travel eSIMs.
Quick answer: what should mobile data cost in Vietnam?
A VOAB planning scenario for moderate data needs using current official local-carrier anchors.
Current named MobiFone tourist-package anchors sit in this range.
Current MobiFone FR30 tourist benchmark; promotions and eligibility can change.
Current official tourist-plan anchors
| Current official MobiFone example | Price | Listed allowance / validity |
|---|---|---|
| TR109 tourist package | 109,000 VND (~US$4.20) | 4GB/day · 20 days + selected calls |
| FR10 | 150,000 VND (~US$5.70) | 50GB · 10 days + selected domestic minutes |
| FR30 | 250,000 VND (~US$9.50) | 150GB · 30 days + selected domestic minutes |
A general prepaid eSIM and a tourist data bundle are different products. MobiFone’s general eSIM page currently gives a 50,000 VND prepaid eSIM benchmark, while the tourist packages above include their own validity and data conditions.
Physical SIM vs local eSIM vs travel eSIM
| Option | Why travellers choose it | What to verify |
|---|---|---|
| Physical local SIM | Works on phones without eSIM; removable local line | Phone unlocked, registration, package and seller |
| Local carrier eSIM | Local product without swapping a physical card | eSIM compatibility, registration, activation process |
| International travel eSIM | Can be installed before arrival | Total GB, validity, local network, hotspot and price |
“eSIM” describes the delivery technology, not the price tier. A local carrier eSIM can be cheaper than a travel eSIM, while an international eSIM may justify a premium if pre-arrival setup matters to you.
Do not compare only the SIM price
Normalize these items before deciding:
- Total package cost, including activation where applicable.
- Validity — seven, ten, twenty or thirty days are not equivalent.
- Usable data and any daily cap or fair-use rule.
- Hotspot/tethering if you plan to work from a laptop.
- Vietnamese phone number if you need local calls/SMS.
- Registration and support if activation goes wrong.
- Network used for third-party travel eSIMs.
Passport registration and phone compatibility
Local mobile service can require identity or passport registration. Follow the carrier’s current process rather than buying an anonymous package from an unclear seller.
Before paying, confirm that your phone is carrier-unlocked. For eSIM, confirm the exact device model supports eSIM and that the eSIM slot is available for travel use.
Airport convenience vs buying later
Airport purchase can be valuable when you want data immediately for maps, ride-hailing and hotel communication. It is not automatically a bad deal.
The comparison should be the exact package: price, allowance, validity and seller. Convenience can carry a premium, but a cheaper city purchase is not better if you spend your first hours offline or making a special trip to save a small amount.
How much data do you actually need?
Light use
Maps, messaging, ride-hailing, email and occasional browsing usually use far less data than video.
Normal holiday use
Frequent social media, photo uploads and navigation can justify a larger package, especially if hotel Wi-Fi is unreliable.
Heavy use / remote work
Video, cloud backup, tethering and calls can consume data quickly. Check hotspot rules and network quality for the places you will actually visit.
The largest allowance is not automatically the best value if most of it expires unused.
A six-step buying checklist
- Confirm your phone is unlocked and, if needed, eSIM-compatible.
- Decide whether you need a Vietnamese phone number or data only.
- Match validity to your actual trip length.
- Compare local SIM, local eSIM and travel eSIM on the same data/validity basis.
- Check registration, hotspot, renewal and support terms.
- Use an identifiable official or authorized channel where practical.
How connectivity fits the Vietnam budget
Connectivity is normally a small one-off arrival cost compared with hotels, intercity transport or major activities. Keep it separate from the recurring meal/accommodation model unless you are calculating a complete all-in trip total.
Use the Vietnam Daily Budget for recurring day-to-day spend and the Vietnam Travel Cost guide for the full trip model.
How VOAB checks SIM and eSIM prices
We prefer official carrier pages for named package prices, date every dynamic offer and label VOAB planning bands separately from carrier tariffs. We do not rank a network as universally “best” without route-specific coverage evidence.

FAQ
How much is a SIM card in Vietnam?
There is no single national price. Current official MobiFone tourist/data anchors support roughly 100,000–250,000 VND for many practical short and 30-day scenarios.
Is eSIM more expensive?
Not necessarily. A local carrier eSIM and an international travel eSIM are different products; compare the whole plan, not the technology label.
Do I need a passport?
Local mobile registration can require identity/passport information. Follow the carrier’s current registration requirements.
Can I buy a SIM at the airport?
Where service is offered, yes. Compare the exact package, validity and seller authorization rather than assuming every airport offer is expensive.
Which mobile network is best in Vietnam?
VOAB does not publish a universal carrier winner without coverage evidence for the traveller’s actual route.
