Round Analysis

Category breakdown for Vietnam.

Coverage

Airalo wins the coverage category for Vietnam with a score of 9.6/10. Airalo connects to Viettel and Vinaphone in Vietnam, part of a 2-network partner roster. 5G reaches major urban areas in Vietnam; rural zones rely on 4G LTE. Airalo scores slightly higher on raw country count but routes through the same carriers in Vietnam. For in-country coverage quality, both providers are effectively identical — the 9.6/10 score reflects network infrastructure strength, not provider-specific coverage gaps.

Pricing

Airalo wins the pricing category for Vietnam with a score of 8.5/10. Plans for Vietnam start at $1.37/GB through Airalo, competitive with regional pricing benchmarks. Available tiers: 1GB: $3.49, 3GB: $7.49, 5GB: $11.09, 10GB: $19.31, 20GB: $27.49. Unlimited daily plans are available from approximately $4.43/day. Pricing scores are adjusted for local market conditions — the 8.5/10 reflects both absolute plan cost and per-GB efficiency relative to Vietnam's infrastructure tier. Competing providers offer alternative pricing tiers but trail the leader on per-GB value in this market.

Speed

Airalo wins the speed category for Vietnam with a score of 9.1/10. Average download speeds in Vietnam reach 52 Mbps. 5G reaches major cities; rural areas rely on 4G LTE. Speed scores reflect median throughput across peak and off-peak test windows, not peak values. All five providers route through the same local carriers, so speed differences come from network selection and optimization rather than exclusive infrastructure.

App

Airalo wins the app category for Vietnam with a score of 8.7/10. It leads on activation flow, UX polish, and feature depth. Saily receives an App boost in Vietnam due to its built-in DNS threat blocking, which functions without a traditional VPN connection. Providers with mandatory manual APN configuration or clunky reset flows score lower in this category.

Support

Airalo wins the support category for Vietnam with a score of 8.5/10. Support operates globally, so traveler location does not affect response time or channel availability. Airalo leads on response time and first-contact resolution rate. Emergency services in Vietnam are reached at 113/115; this is separate from provider support but relevant context for travelers. Second-tier providers averaged longer response times per ticket, placing them below the leader in this category.
