Vietnam eSIM Compare: My Journey with Viettel, Mobifone, and Vinaphone (2025 Review)
“Which eSIM should I buy for Vietnam?” – That’s what I googled before landing in Ho Chi Minh City. As a traveler who hates FOMO and dead zones, I decided to put Vietnam’s big three – Viettel, Mobifone, and Vinaphone – to the test myself. Here’s my honest, no-fluff comparison (plus real tips you won’t find on boring lists).
eSIM in Vietnam: Instant Connection, No Headaches
I’ll never queue for a physical SIM again. Every eSIM took under five minutes: just scan the QR, activate, and I was online before my backpack hit the hostel bed. No taxi scams, no paperwork, no lost tiny SIMs in airport bathrooms. Vietnam eSIM compare? Game-changer, every time.
Stop #1: Viettel eSIM – The Coverage King
First leg: motorbiking through Ha Giang, the far north. I chose Viettel because everyone on Reddit and Google Maps said, “If you’re going rural, don’t risk anything else.”
- Coverage: 4G (and even 5G in big towns) everywhere, including rice paddies, foggy mountain villages, random waterfalls… you get the idea.
- Speed: Fast enough for TikTok, WhatsApp video, even quick work calls.
- Drawback: Most plans are data-only — no Vietnamese number for Grab or banking SMS.
“If your Vietnam plans include trekking, motorbiking, or even a remote eco-lodge, Viettel is your best bet.”
Stop #2: Mobifone eSIM – The All-Rounder (with Local Number)
Back in Hanoi, I switched to Mobifone for a month. Why? Because I needed a Vietnamese number for Grab, Zalo, and that weird moment when my Airbnb host wanted to call me directly.
- Coverage: Excellent in cities and along the Reunification Express train route. Some valleys in Sapa were weaker than Viettel, but I never lost signal in Da Nang or Hoi An.
- Phone Number: Mobifone wins if you want full local access: call a cab, receive SMS for banking, open a local food delivery account, etc.
- Long-stay: Mobifone’s 30–90 day eSIM plans are the top pick for digital nomads and expats. Every coworker I met used it.
“Mobifone is like that friend who’s not flashy but always there when you need them.”
Stop #3: Vinaphone eSIM – The City Slicker
For my budget Saigon week, I grabbed a Vinaphone eSIM. If you stay in major cities and just want cheap, basic internet (and a local number for the odd Grab), it does the job.
- Coverage: Good in Ho Chi Minh City, Nha Trang, and most urban areas. But my beach trip to Phu Quoc? Signal faded after the ferry docked.
- Price: Cheapest plans, perfect for short trips or students.
- Limitation: Don’t expect miracles outside metro zones.
“Vinaphone: city cafes, coworking spaces, and a week of street food Instagrams? Perfect. Heading to the jungle? Maybe not.”

| Mobifone | Great all-rounder, local number, solid for long stay | Expats, digital nomads, urban/rural mix | Very good (cities, highways, coast) | Yes |
