Airalo operates as one of the most recognizable names in the budget eSIM category, offering Vietnam connectivity through partnership with Viettel, the country's largest mobile network provider. Prices start at $4.50 for 1GB lasting 7 days and go up to around $42 for 20GB plans with longer durations. The provider focuses on affordable fixed-data packages that appeal to budget-conscious travelers seeking predictable costs.
Airalo Vietnam Plan Options:
Airalo's strength lies in its partnership with Viettel infrastructure, ensuring excellent coverage not just in urban areas like Hanoi and Ho Chi Minh City but also in remote regions like Ha Giang and Phong Nha-Ke Bang National Park. This network choice provides reliable connectivity throughout Vietnam's diverse terrain, from coastal areas to mountainous regions.
However, Airalo's limitations become apparent for heavy data users and multi-country travelers. The fixed data allowances create anxiety about usage monitoring, and when limits are reached, connectivity stops entirely without options for emergency top-ups. Plans cannot be extended with additional days, requiring new purchases if your trip extends beyond the original validity period. Each destination requires a separate eSIM installation through QR code scanning, creating management overhead for multi-country Southeast Asian trips.
Holafly specializes in unlimited data plans, offering options ranging from $21 for 5 days up to $99 for longer durations. Their Vietnam eSIMs provide coverage through partnerships with all three major Vietnamese carriers: Viettel, Mobifone, and Vinaphone. The provider markets themselves as the premium unlimited option for travelers who don't want to monitor data consumption.
Holafly Vietnam Plan Options:
Holafly's unlimited claims come with significant caveats, as speed performance can be frustrating, making it a tough sell despite the unlimited data promise. The provider renames networks to "Holafly" rather than showing the actual carrier, which can make troubleshooting connectivity issues more challenging. Independent testing reveals that while signal strength remains solid, actual speeds often disappoint users expecting premium performance.
The pricing structure reflects Holafly's positioning as a premium provider, but the unlimited plans are more expensive and may not be worth it for light data users who don't need truly unlimited access. For travelers planning multi-country trips, each destination requires a separate eSIM purchase and installation, limiting the value proposition compared to global alternatives.
Nomad offers user-friendly eSIM solutions with competitive pricing and reliable data coverage in Vietnam through partnerships with Mobifone networks. Their plans range from $6 for smaller data packages to $50 for larger allowances, with validity periods from 7 to 45 days. The provider targets frequent travelers with flexible data packages and regional options.
Nomad Vietnam Plan Options:
Nomad's app receives praise as well-built and functional, offering detailed plan information and generally being one of the favorite interfaces among users. The provider includes a loyalty program that frequent travelers appreciate. The flexibility in data packages allows travelers to customize their connectivity based on actual usage patterns rather than accepting predetermined tiers.
However, Nomad partnerships with Mobifone for 4G network coverage may not provide the same comprehensive reach as Viettel-based alternatives, particularly in remote areas of Vietnam. Some mixed reviews have emerged regarding connectivity and activation processes, suggesting inconsistent performance across different regions and time periods.
Understanding the real-world setup complexity reveals significant differences between traditional eSIM providers and modern alternatives that impact your travel experience.
All traditional providers follow similar multi-step processes that require technical knowledge and troubleshooting skills:
| Step | Traditional Process | Common Issues | Time Required |
|---|---|---|---|
| Research | Compare plans across multiple providers | Confusing pricing structures | 15-30 minutes |
| Purchase | Create account and payment processing | Limited payment options | 5-10 minutes |
| Installation | Scan QR code and manual configuration | QR code scanning failures | 10-15 minutes |
| Activation | Enable data roaming and test connectivity | Network connection problems | 5-15 minutes |
| Management | Monitor usage and purchase top-ups | App complexity and limitations | Ongoing |
Traditional eSIM providers typically require QR code scanning for installation, with some offering alternative installation methods when QR codes fail to scan properly. This process must be repeated for each destination when traveling to multiple countries, creating significant management overhead.
Second-generation eSIM technology eliminates traditional complexity through automation:
| Step | Truely Process | Advantage | Time Required |
|---|---|---|---|
| Research | Single provider for all destinations | No comparison needed | 2-3 minutes |
| Purchase | One global plan covers 190+ countries | Simplified decision making | 2-3 minutes |
| Installation | One-click automated setup | No QR codes or manual configuration | 1-2 minutes |
| Activation | Automatic upon arrival anywhere | No manual intervention required | Instant |
| Management | Pause & Resume between trips | Only pay for days actually used | Minimal |
Truely's one-click installation process takes just a few minutes and works on both iOS and Android devices. The Switchless™ technology automatically connects wherever you go, eliminating the need for troubleshooting connectivity issues.
Independent testing reveals significant variations in network performance, speed, and reliability across different eSIM providers in Vietnam.
Recent independent testing in Vietnam shows Ubigi delivering the fastest speeds at 181 Mbps, followed by AloSIM at 120 Mbps on Mobifone networks, and Airalo at 112 Mbps on Viettel networks. These results demonstrate that network partnerships significantly impact actual performance beyond advertised specifications.
Network Performance by Provider:
Signal strength generally remains solid across major providers, but speed performance varies significantly based on network partnerships and traffic management policies. Single-network providers like Airalo and Nomad face limitations when their chosen carrier has coverage gaps or congestion issues.
Real-world testing reveals that in major cities like Hanoi and Ho Chi Minh City, most providers deliver steady internet connectivity for navigation and transportation apps. However, in remote areas like Ha Giang, signal reliability becomes more variable with some providers experiencing significant connectivity issues.
Urban vs Rural Performance:
Truely's multi-network approach automatically switches between available carriers, ensuring optimal performance regardless of location within Vietnam or when crossing into neighboring countries.
Understanding real-world costs across different travel patterns reveals why pricing structures matter more than headline rates:
| Travel Scenario | Airalo Cost | Holafly Cost | Nomad Cost | Truely Cost | Best Value |
|---|---|---|---|---|---|
| Weekend Ho Chi Minh City (3 days) | $4.50 (1GB wasted) | $21 (5 days minimum) | $6 (1GB for 7 days) | $7.50-16.56 | Truely |
| One Week Vietnam Tour | $11-16 (3-5GB) | $29 (7 days unlimited) | $12-18 (3-5GB) | $17.50-38.64 | Truely |
| Two Week Business Trip | $26-42 (10-20GB) | $51 (15 days unlimited) | $28-45 (10-20GB) | $35-77 | Truely |
| One Month Digital Nomad | $42 (20GB max) | $99 (varies by length) | $45 (20GB for 45 days) | $77-166 | Truely |
| Multi-Country Southeast Asia | Multiple eSIMs required | New plan each country | Multiple eSIMs needed | $77-166 (30 days) | Truely |
Hidden Costs Analysis: Traditional providers often carry additional expenses that aren't immediately apparent:
Truely's pricing structure rewards longer commitments, making it cost-effective for extended trips or digital nomads who need consistent coverage over weeks or months.
Truely launched in July 2023 with proprietary Switchless™ technology that allows users to install one eSIM that automatically works across 190+ destinations without any additional setup or switching. This represents a fundamental advancement over traditional eSIM technology.
