Airalo -- Best Overall Coverage
Airalo scores highest on Coverage at 5.0 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.
Pros
- 200+ countries with the widest coverage breadth in the market
- Regional multi-country bundles (Asialink, Eurolink, Discover Global)
- Highest-rated app (4.8/5 iOS, 4.6/5 Android) 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
- Customer support slower than premium providers (4-6 hour email response)
HelloRoam -- Best Coverage + Value
HelloRoam scores 8.6/10 overall and prices Vietnam from $3.50/GB, undercutting Airalo's $4.50/GB and Saily's $3.99/GB, while its 204+ carrier partnerships route through Viettel, the network that held the steadiest signal across Sapa and the Hai Van Pass in testing. Its 63-language interface and 31+ supported currencies help with Vietnam's 17.6 million annual arrivals from outside the usual English-speaking source markets.
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
- 31+ local currencies supported at checkout
- 63-language interface for non-English travelers
Cons
- Email-only support with 12-24 hour response times
- Newer brand (launched August 2025) with shorter track record
- App store ratings still building compared to Airalo
Holafly -- Best Unlimited Data
Holafly is the only provider in this comparison selling 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. Its Pricing score of 4.8 leads this matrix, though Vietnam's own $1.37/GB fixed-plan floor already undercuts unlimited pricing for shorter stays.
Pros
- Unlimited daily data from $2.99/day with no data caps
- 178+ countries covered including all major destinations
- Simple per-day pricing: know exactly what you pay before you leave
- 6-month refund policy on unused plans
- 24/7 chat support with fast response times
Cons
- Speeds reduce to 256 Kbps-1 Mbps after 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 150-country footprint trails Airalo's 200+ on raw breadth.
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
- 150 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
- 150 countries, a narrower footprint than Airalo
- 12-24 hour support response times
Nomad -- Best Budget Option
Nomad scores highest on Pricing at 4.9 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 3.5, the lowest of the five, and 112-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.
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 24-48 hour response times
- Basic app compared to Airalo and Saily
- 112 countries, the narrowest footprint among the five providers
- Limited plan variety in some countries

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.

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?
Holafly is the only provider in this comparison with unlimited daily Vietnam plans, priced from $2.99/day, which scores highest on Pricing at 4.8 for travelers who exceed the country's 1.2GB average daily use. Airalo, HelloRoam, Saily, and Nomad 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?

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?
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 four providers compared here include VPN access as a built-in feature.
