When I planned my 2025 trip to Vietnam, one of my top concerns was staying connected. I wanted to explore from Hanoi down to Ho Chi Minh City, with side trips to Sapa, Hue, Da Nang, and Hoi An. From past experience, I knew that not all mobile networks in Vietnam perform equally well, especially in rural or mountainous areas. That’s why I decided to try Viettel’s Tourist eSIM, known for its strong nationwide coverage.

Buying and Setting Up Viettel Tourist eSIM

I purchased my Viettel eSIM through GoVnSIM. The process required an eKYC step: I uploaded a photo of my passport’s main page. Within about ten minutes, I received a confirmation email with a QR code attached. Scanning the QR on my iPhone was quick — less than three minutes later, my phone displayed ‘Viettel LTE.’ I loved that I didn’t have to queue at the airport or deal with physical SIM cards.

During my month-long journey, I put the eSIM to the test across different regions:

– **Hanoi:** I relied on it from the very first day. Grab rides, Google Maps through the Old Quarter’s tiny alleys, and messaging on Zalo all worked smoothly.
– **Sapa:** Trekking in the mountains, I still had signal in many areas. I used hotspot to share my connection with friends, which surprised me given the remote setting.
– **Hue & Da Nang:** I tested the connection while working remotely at riverside cafés. Video calls and cloud uploads were consistent, with occasional switches between 4G and 5G.
– **Hoi An:** During the lantern festival, I livestreamed the glowing streets without any lag. Friends abroad could watch it in real time.
– **Ho Chi Minh City:** The eSIM handled everything from ordering GrabFood late at night to receiving OTP codes for payments.

✅ Pros:

– Strongest coverage in Vietnam, even in remote areas.

– 5GB/day was enough for streaming, navigation, and work.

– Hotspot worked flawlessly, even in Sapa.

– Quick activation through QR code after passport upload.

⚠️ Cons:

– Requires passport upload (eKYC) before activation.

– Data-only plan — no Vietnamese phone number included.

– Daily data cap may not suit ultra-heavy users.

Final Thoughts

Overall, choosing Viettel’s Tourist eSIM was the right decision for my trip. The coverage gave me peace of mind, especially during treks and rural excursions, and I never felt disconnected. For travellers who want convenience and the widest coverage in Vietnam, this is a strong choice.

I ordered mine via GoVnSIM and had it running within minutes. If you’d like more details on Viettel’s Tourist eSIM, check their full guide here: https://govnsim.com/viettel-vietnam-tourist-esim-complete-guide-for-travelers-2025/
