The gold standard for any visitor. Highly recommended for business travelers and families who demand the highest network reliability and zero downtime.

City Explorers Ideal for those staying primarily in major hubs like Hanoi or Ho Chi Minh City who balance stability with cost-effectiveness.

🏆 Conclusion: Why Viettel is Our Top Recommendation
For any traveler visiting Vietnam—whether you're navigating urban jungles or exploring remote mountains and coastlines—Viettel is the clear winner.
The Best Choice: Viettel (Make Every Moment Count)
You've already invested thousands in flights and hotels; don't let poor connectivity compromise your precious holiday. As Vietnam's market leader with a state-owned military background, Viettel guarantees the most extensive coverage and highest stability. While plans may carry a slight premium, the peace of mind of having a seamless connection—especially in non-urban gems like Ha Long Bay and Sa Pa—makes Viettel the unrivaled choice for quality and reliability.
II. How to Choose the Best Vietnam Telco & eSIM?
When selecting a Vietnam mobile operator, your itinerary and travel destinations should be your primary consideration.
Network Coverage: As Vietnam's largest telco, Viettel offers the most extensive coverage. Its network remains exceptionally stable from bustling cities to remote villages—making it the top choice for travelers visiting off-the-beaten-path locations like Sa Pa, Ha Giang, or the Mekong Delta.
Provider Reliability: Since an eSIM is a digital product, the quality of after-sales support is just as important as the network itself. Real-time assistance, Mandarin/English customer support, and a clear refund policy are essential to a stress-free trip. We recommend choosing brands that offer live human support (not just AI bots) to handle any unexpected connectivity issues.
Installation Methods: While most 2026 plans support instant QR code installation for "buy-and-go" convenience, some legacy plans still require physical SIMs. Always verify your device’s eSIM compatibility before purchasing.
III. Why Choose eSIM? The Modern Choice for Vietnam Travel
The biggest advantages of eSIM technology are unmatched convenience and security:
No Physical Swapping: Say goodbye to fumbling with tiny SIM cards and tiny pins. You won’t risk losing your original SIM card while abroad.
Instant Activation: Simply scan a QR code to download and activate your data plan. You can get connected the moment you land.
Dual SIM Functionality: Keep your home SIM active for important calls or bank OTP (One-Time Password) SMS, while using the eSIM for high-speed local data.
Ultimate Flexibility: Perfect for frequent travelers or multi-country trips; you can easily switch between different international data plans with a few taps.

VI. eSIM FAQ & Customer Support Guide
1. How does Peanutmo Travel eSIM help me save money?
We offer flexible data plans and durations for major global destinations. You can choose a package that perfectly matches your itinerary, avoiding expensive "unlimited" plans that often go to waste. Pay only for what you need!
2. Do I need to provide my passport or ID for registration?
No. We prioritize your privacy and data security. Unlike traditional physical SIM cards that may require tedious forms or personal ID, purchasing a Peanutmo eSIM only requires your email address. The process is fast, simple, and secure.
3. When should I install my Peanutmo eSIM?
We recommend installing your eSIM on the day of departure or the day before, while you have a stable internet connection.
Pro Tip: Since some plans activate immediately upon installation, it is best to set it up at the airport before you fly to maximize your data duration.
Important: Install it while you still have Wi-Fi. Once you land at your destination, simply turn on Data Roaming and set the eSIM as your primary cellular data source.
4. Can I still receive calls and SMS on my original number abroad?
Yes. Because you don't need to remove your physical SIM card, you can keep your original number active to receive calls and SMS (useful for bank OTPs). Please note that your home carrier may still charge international roaming fees for these services.
5. Does my smartphone support eSIM?
You can find a list of compatible models on our product pages. However, since compatibility varies by region and carrier restrictions, we strongly recommend checking with your mobile provider or contacting our support team for a quick compatibility check.
