HelloRoam -- Highest Composite Score
HelloRoam scores 4.64/5 overall on our 2026 rubric, with App 5.0/5 and Support 5.0/5, and prices Vietnam from $3.50/GB plus unlimited from $5, undercutting Airalo's $4.50/GB and Saily's $3.99/GB, while 204+ carrier partnerships route through Viettel, the network with the widest published reach across Sapa and the Hai Van Pass. The iOS and Android app, 63-language interface, and 31+ supported currencies help with Vietnam's 17.6 million annual arrivals from outside the usual English-speaking source markets.
Dimension scores, 0-5 on our rubric
Pros
- 186 countries with 204+ carrier partnerships for reliable local routing
- Fixed plans from $3.50/GB across popular destinations
- Unlimited plans from $5 for short stays, scaling by duration
- iOS and Android app with in-app top-up, add-destination, and usage alerts
- Live chat, WhatsApp, and email support, including real-time channels
- 31+ local currencies supported at checkout
- 63-language interface for non-English travelers
Cons
- Newer brand (launched August 2025) with shorter track record
- 186 countries, behind Airalo's 200+ catalogue
Airalo -- Widest Coverage Catalogue
Airalo scores highest on Coverage at 4.9/5 in this matrix, and its Asialink bundle folds Vietnam into a single eSIM covering 15 other Southeast Asian countries, useful for a trip continuing into Cambodia or Thailand. That reach comes at a $4.50/GB floor, the highest fixed rate among the five providers compared here for Vietnam.
Dimension scores, 0-5 on our rubric
Pros
- 200+ countries with the widest coverage breadth in the market
- Regional multi-country bundles (Asialink, Eurolink, Discover Global)
- Automatic in-app install with real-time data tracking and hourly runtime estimates
- Airmoney cashback rewards (5-10% depending on loyalty tier)
- Established brand since 2019 with proven reliability
Cons
- Per-GB pricing higher than budget alternatives
- Unlimited plans available in select markets only, not all 200+ destinations
- No live chat or WhatsApp channel: support runs on email and in-app messaging
Holafly -- Best Unlimited Daily Rate
Holafly sells unlimited daily Vietnam plans from $2.99/day, which pays off once a traveler exceeds the country's 1.2GB average daily use across an 8-day trip. HelloRoam also sells unlimited from $5. Holafly's Pricing score of 4.8 leads the daily unlimited rate in this matrix, though Vietnam's own $1.37/GB fixed-plan floor already undercuts unlimited pricing for shorter stays.
Dimension scores, 0-5 on our rubric
Pros
- Unlimited daily data from $2.99/day with no data caps
- 160+ countries covered including all major destinations
- Simple per-day pricing: know exactly what you pay before you leave
- 180-day refund policy on unused plans
- 24/7 chat support alongside email
Cons
- Speeds reduce after the daily fair use threshold on most plans
- Hotspot tethering limited to 1 GB/day on select destinations
- Not cost-effective for light data users (under 3 GB/trip)
- Fewer countries than Airalo
Saily -- Best for Privacy
Saily bundles NordVPN with every Vietnam plan, a relevant feature given the government blocks many VPN services in the country while leaving Facebook and Google generally accessible. Its $3.99/GB rate runs above HelloRoam's $3.50/GB, and its 200-country footprint trails Airalo's 200+ on raw breadth.
Dimension scores, 0-5 on our rubric
Pros
- Backed by NordVPN parent company Nord Security with proven privacy infrastructure
- Integrated VPN protection included on every plan at no extra cost
- Clean, privacy-focused app with VPN toggle inside the eSIM interface
- 200 countries with strong European coverage
- 30-day refund policy
Cons
- Email-only support with no live chat or WhatsApp for urgent help
- Fixed data plans only; no unlimited daily tier
- 200 countries, just behind Airalo's 200-plus
Nomad -- Best Budget Per-GB Rate
Nomad scores highest on Pricing at 4.8 and counts Vietnam among its discounted Southeast Asia markets, with a $3.00/GB general rate that beats every fixed-data competitor except the country's own $1.37/GB floor. Its Support score of 3.9, the lowest of the five, and 200-country footprint are real trade-offs on a longer Vietnam itinerary that crosses from Hanoi in the north to Ho Chi Minh City in the south.
Dimension scores, 0-5 on our rubric
Pros
- Competitive pricing starting from $3.00/GB in Southeast Asia
- Simple, fast checkout with no account required in many cases
- Lowest per-GB rates for Thailand, Vietnam, South Korea, and Japan
- Plans start at a low entry price for short trips
Cons
- Email-only support with no live chat, WhatsApp, or phone channel
- Basic app compared to Airalo and Saily
- 200 countries, behind only Airalo among the five providers
- Limited plan variety in some countries

FAQ
Vietnam eSIM questions, answered
Which eSIM provider has the best coverage in Vietnam?
Which eSIM provider has the best coverage in Vietnam?
HelloRoam leads the 2026 composite at 4.64/5 in our comparison matrix. Airalo leads coverage breadth at 4.9/5, backed by a 200-country footprint and an Asialink bundle spanning Vietnam plus 15 neighboring countries. HelloRoam scores 4.5/5 on the rubric on Coverage with 204+ carrier partnerships routed through Viettel, the network that held the steadiest signal across the Hai Van Pass and Sapa while Vinaphone dropped in remote Ha Giang.
How do eSIM speeds compare in Vietnam?
How do eSIM speeds compare in Vietnam?
Vietnam's 5G network covers Hanoi and Ho Chi Minh City through Viettel, while the rest of the country runs on 4G LTE, the same tier for all five providers in this comparison since each routes through the same carrier mix. Speed differences come down to which city or region a trip covers, not provider engineering.
Which eSIM has the cheapest per-GB rate for Vietnam?
Which eSIM has the cheapest per-GB rate for Vietnam?
Nomad posts the highest Pricing score in this matrix at 4.9, with a $3.00/GB general rate built for Southeast Asia, ahead of HelloRoam's $3.50/GB and Saily's $3.99/GB. Vietnam's own market floor checks in at $1.37/GB, among the cheapest mobile data prices in the world, with local SIMs running under $1/GB from carrier stores.
Does an eSIM work with Grab and Zalo in Vietnam?
Does an eSIM work with Grab and Zalo in Vietnam?
Grab works with international phone numbers, so any of the five eSIM providers in this comparison support ride-hailing in Vietnam without a local SIM. Zalo, Vietnam's dominant messaging app used more than WhatsApp by locals, also runs over data alone, so an e-sim covers both apps without needing a separate Vietnamese number.
Which provider offers unlimited data for Vietnam travel?
Which provider offers unlimited data for Vietnam travel?
HelloRoam sells unlimited from $5, and Holafly sells unlimited daily Vietnam plans from $2.99/day, which scores highest on the daily unlimited rate for travelers who exceed the country's 1.2GB average daily use. HelloRoam, Airalo, Saily, and Nomad also sell fixed-GB plans, which price lower for Vietnam's typical 8-day trip and roughly 10GB of total usage.
Is an eSIM cheaper than a local SIM in Vietnam?
Is an eSIM cheaper than a local SIM in Vietnam?
Local Vietnamese SIMs cost $3 to $8 for 4GB to 10GB over 30 days, some of the cheapest mobile data in the world, but require passport registration under real-name rules in effect since 2018. Every e SIM in this comparison skips that registration step, though Vietnam's own $1.37/GB floor still runs higher than the cheapest local SIM rate.
Which eSIM works best for Vietnam's restricted VPN access?
Which eSIM works best for Vietnam's restricted VPN access?
HelloRoam leads the 2026 composite at 4.64/5 in our comparison matrix. Saily is the only provider in this comparison with NordVPN bundled into every plan, a relevant feature in Vietnam, where the government blocks many VPN services while leaving Facebook and Google generally accessible. Saily's $3.99/GB rate runs above HelloRoam's and Nomad's, but none of the other five providers compared here include VPN access as a built-in feature.
