Beyond the price tag
Ubigi Vietnam eSIM hotspot 5G and fair-use rules
Quoted from Ubigi's own published policy rather than paraphrased — these are the terms that decide whether a plan for Vietnam survives a real trip.
Hotspot and tethering
AllowedNo separate cap
Data sharing is explicitly allowed and hotspot traffic counts against the plan's own allowance rather than a separate tethering budget.
Speed and 5G
5G available15–250 Mbps
Typical real-world download on the fastest host network, Viettel. Actual speed depends on which mast your phone picks and how busy it is.
Fair-use threshold
Varies by plan - published per plan page
Drops to 1 - 2 Mbps
Ubigi publishes a different threshold on each unlimited plan, and the spread is large - two plans at the same price have been seen giving 15 GB total versus 5 GB/day. Read the fair-use line on the exact plan page you are buying from.
Top-ups
AvailableTopping up is supported in the Ubigi account dashboard.
The masts behind the plan
Which network does Ubigi ride in Vietnam
Ubigi owns no towers in Vietnam. This plan connects to the local host carriers Mobifone, Viettel, Vinaphone — so coverage, speed and rural reach follow those masts rather than the brand on the voucher.
Viettel
5G20–250 Mbps
Vietnam's largest — the best coverage beyond Hanoi and Ho Chi Minh City, including Ha Long Bay.

Before you buy
Things to know about Vietnam before you pick a plan
Country-level facts, not brand claims — they apply to any eSIM you buy for Vietnam, Ubigi's included.
-
Vietnam requires passport registration for every SIM including eSIMs - expect a quick ID upload during purchase.
-
Viettel is the only network that reliably covers Ha Long Bay and northern mountain routes; most travel eSIMs default to it.
Price by trip length
What Ubigi costs by trip length in Vietnam
The same trip priced two ways — Ubigi's own cheapest plan that stays valid for the whole stay, against the cheapest rival plan covering the same days in Vietnam.
| Trip length | Ubigi cheapest | Cheapest rival in Vietnam | cheaper |
|---|---|---|---|
| 3 days | $6.90 15 days · 3GB | $1.99 3 days · 1GB · Roami | Roami cheaper |
| 5 days | $6.90 15 days · 3GB | $2.00 7 days · 1GB · Roamic | Roamic cheaper |
| 7 days | $6.90 15 days · 3GB | $2.00 7 days · 1GB · Roamic | Roamic cheaper |
| 10 days | $6.90 15 days · 3GB | $2.84 30 days · 1GB · Yesim | Yesim cheaper |
| 15 days | $6.90 15 days · 3GB | $2.84 30 days · 1GB · Yesim | Yesim cheaper |
| 30 days | $12.90 30 days · 10GB | $2.84 30 days · 1GB · Yesim | Yesim cheaper |
Pick your trip length and this re-reads the plan table above on the spot — the cheapest plan whose validity still covers the whole trip, against the cheapest rival in the same country.

Only plans whose validity covers the whole trip are counted here, so a 30-day trip is priced with a 30-day plan rather than a 5-day one stacked up. Each pick shows its data allowance next to the price — a 500MB trial pack undercuts a 5GB plan for a reason.
One column per brand, cheapest plan that covers the whole trip. Rivals are the other providers we track in Vietnam.

Who it fits
Should you buy Ubigi for Vietnam
Buy it if

- +You are travelling for 30 days or more — 10GB / 30 Days covers it for $12.90.
- +You are on a short break — 10GB / 7 Days runs 7 days for $10.90.
Look elsewhere if
- –You are going for fewer than 7 days — its shortest plan runs 7 days

- –Cheapest headline price is all that matters — Yesim's smallest plan in Vietnam starts at $0.51, and that buys 300MB.
Honest trade-offs
Where Ubigi wins and loses in Vietnam

- –Its shortest plan runs 7 days, so a shorter trip still pays for 7
- –Ubigi sells 4 trip lengths here while Roamic sells 30
- –Data-only plans with no local phone number

FAQ
Ubigi Vietnam eSIM questions
How much does Ubigi charge for Vietnam?
Ubigi sells 9 plans for Vietnam, from $6.90. Its best rate is $0.74/GB, drawn from the 10 provider price sheets we track for this destination. All prices are in USD as listed by Ubigi and exclude promo codes.
Can I share my Ubigi Vietnam eSIM with a laptop?
Tethering is governed by Ubigi's own rule rather than by the country. What we recorded from Ubigi's documentation for Vietnam plans is No separate cap. That is the publisher's wording, not our paraphrase — the full quote sits in the policy cards above. If you work from a laptop for hours a day, treat this line as the deciding factor between Ubigi and a metered alternative, because hotspot traffic drains the same allowance as the phone itself.
Which network does Ubigi use in Vietnam?
Ubigi owns no towers in Vietnam, so your data rides the local host carriers — Mobifone, Viettel, Vinaphone. The fastest of those sustains roughly 250 Mbps, and every one of the 185 Vietnam plans we track connects to the same local networks.
Is Ubigi or Yesim the better Vietnam eSIM?
Ubigi's cheapest plan here is $6.90; Yesim's is $0.51, though that entry price buys 300MB. The full ranking with every plan — allowance and $/GB side by side — sits in the Vietnam eSIM comparison.
Does Ubigi have good reviews for Vietnam?
We publish no star rating, and that is deliberate: Trustpilot runs separate regional storefronts, so the same brand holds several scores at once, and quoting one of them as the rating would mislead. The reviews themselves are at <a href="https://www.trustpilot.com/review/cellulardata.ubigi.com" rel="nofollow noopener" target="_blank">Ubigi on Trustpilot</a>. What we verify instead is measured on this page — 9 Ubigi plans for Vietnam starting at $6.90.
Does Ubigi work in Vietnam?
Yes. Ubigi owns no towers in Vietnam, so your plan rides the local host networks — Mobifone, Viettel, Vinaphone — and every one of the 185 Vietnam plans we track connects to that same set. Installs that fail are almost never a coverage problem. They come down to three causes: the handset is still carrier-locked, the eSIM line's data roaming is switched off, or the phone stays on the old line for mobile data after the profile installs. All three are fixable at home, which is why installing on your own Wi-Fi beats doing it at the airport. Ubigi sells 9 packages here from $6.90, so the host network is not what separates it from its rivals.
How do I activate my Ubigi eSIM for Vietnam?
Install it while you still have home Wi-Fi: Ubigi issues either a QR code or an in-app profile, and the install itself takes minutes. Leave the line switched off until you land if you want the validity window to start on arrival, and turn data roaming on for that line. On this page Ubigi sells 9 separate Vietnam packages, from $6.90 each, so match one to your trip length rather than planning to top up abroad. The generic walkthrough is in our eSIM installation guide.
