My Vietnam Adventure: How a Vietnam eSIM Saved Me in Ha Long Bay
Share
Two days into my solo trip in Vietnam, I found myself adrift—literally. Somewhere between the limestone cliffs of Ha Long Bay, my tour boat lost signal, my driver couldn’t reach me, and I had no way to call or text anyone. That’s when I realized: having just data wasn’t enough. I needed a real Vietnam eSIM—with a local number.
Luckily, I discovered Chillaxsim just in time.
Why a Vietnam eSIM Isn’t Just About Data
Before my trip, I figured all I needed was Google Maps and Instagram. I bought a cheap data-only eSIM from a random site and thought I was good. But when I needed to receive a text from my hotel, or call my Grab driver, or verify an app that required a Vietnamese phone number, I was stuck.
That’s where Chillaxsim changed the game.
They offer not only flexible data-only Vietnam eSIMs, but also powerful Viettel and Vietnamobile plans with local numbers—ideal for travelers who want to do more than scroll.
Real Travel, Real Needs: My eSIM Story in Ha Long Bay
Here’s how it went down.
I had just left Hanoi for Ha Long Bay, one of Vietnam’s most breathtaking destinations. My tour guide was supposed to text me the exact pier location. But guess what? My data-only eSIM couldn’t receive SMS. No phone number. No texts.
Total panic.
I had no idea where to go and couldn’t call anyone. That night back in my hostel, I searched for a better solution and found Chillaxsim’s Viettel eSIM plan, which comes with 5GB/day and a local Vietnamese number. It was exactly what I needed.
I bought it through their official product page, scanned the QR code, and followed their easy setup instructions. I was online—and reachable—within 10 minutes.
Why Chillaxsim’s Vietnam eSIM Was a Lifesaver
Here’s what made the Chillaxsim eSIM a game-changer for the rest of my Vietnam adventure:
✅ Vietnamese Phone Number: Used it to call hotels, receive booking confirmations, and use local delivery/rideshare apps.
✅ 5GB High-Speed Data per Day: Streamed Spotify on the bus to Ninh Binh without a glitch.
✅ Top-tier Network via Viettel: Fast, stable signal from Hanoi to Ha Long and even remote areas.
✅ Instant Activation: Just scanned and connected—no waiting, no kiosk, no paperwork.
✅ Hotspot Support: Shared my connection with a fellow traveler whose SIM stopped working.
For a solo traveler like me, being connected wasn’t just convenient—it was safe.
