HelloRoam -- Highest Composite Score
HelloRoam scores 4.64/5 on our rubric overall for Hanoi, with App 5.0 and Support 5.0 on an iOS and Android app, live chat plus WhatsApp, and a 180-day refund. Plans price from $3.50/GB, the second-lowest position in the fixed-rate field, behind only Nomad, with unlimited from $5. Its 204+ carrier partnerships route through Vietnam's local networks directly rather than through a roaming intermediary.
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 4.45/5 on this scorecard in this comparison's matrix, and its $4.50/GB Hanoi rate runs more than three times the local $1.37/GB floor, the same premium this comparison finds across Vietnam generally. The 200-plus-country footprint and Asialink bundle matter more on a Hanoi stop that continues into wider Southeast Asia than on a single-city stay.
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's $2.99/day unlimited rate for Hanoi undercuts the local $4.43/day unlimited price by close to a third, one of the wider unlimited-tier gaps this comparison tracks in Southeast Asia. HelloRoam also sells unlimited from $5. The Holafly 2GB daily volume before the throttle applies suits a day spent around the Old Quarter or on a Sapa day trip.
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's $3.99/GB Hanoi rate comes bundled with NordVPN on every plan, a more direct workaround for Vietnam's government-level VPN blocking than in destinations where VPN access is already unrestricted. Saily has no regional bundle for Vietnam. Its 200-country footprint gives it a Southeast Asia reach similar to Holafly's, though at a fixed rather than unlimited structure.
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's $3.00/GB rate remains the lowest fixed floor in the five-provider matrix for Hanoi, though the local $1.37/GB rate still beats it by more than a dollar, consistent with the gap this comparison finds across Vietnam. Nomad has no regional bundle for Vietnam. Its 200-country footprint matters less on a Vietnam-only trip than on one continuing beyond Southeast Asia.
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
Hanoi eSIM questions, answered
Who leads the Hanoi eSIM comparison?
Who leads the Hanoi eSIM comparison?
HelloRoam leads the 2026 composite at 4.64/5 in our comparison matrix. Airalo, Holafly, Saily, and Nomad follow on coverage breadth, daily unlimited, privacy, and per-GB pricing.
Which eSIM has the cheapest per-GB rate for Hanoi?
Which eSIM has the cheapest per-GB rate for Hanoi?
Nomad's $3.00/GB is the lowest fixed rate among the five providers compared, followed by HelloRoam at $3.50/GB. Hanoi's own local carrier floor still runs cheaper at $1.37/GB, though registering a local SIM requires passport-based real-name registration that none of the five eSIMs need.
Does Hanoi have 5G coverage?
Does Hanoi have 5G coverage?
Yes. Viettel became the first carrier to launch 5G service in Vietnam, confirmed specifically for Hanoi and Ho Chi Minh City in 2024, rather than as a nationwide rollout. Coverage outside these two cities still runs on 4G in most areas.
Is a VPN blocked on an eSIM in Hanoi?
Is a VPN blocked on an eSIM in Hanoi?
Partially. Vietnam's government blocks many VPN services at the network level regardless of which of HelloRoam, Airalo, Holafly, Saily, or Nomad carries the connection, though Facebook and Google generally remain accessible without one. Saily bundles a NordVPN connection into every plan, a more direct workaround than relying on a separate VPN app.
