MobiFone is Vietnam’s third-largest carrier. It covers most cities and popular tourist areas well — but drops off outside urban centers faster than Viettel and Vinaphone. For tourists who stay in Hanoi, Ho Chi Minh City, Da Nang, or coastal towns, it works fine. For anyone heading to Ha Giang, Sapa, or rural Vietnam, it’s the wrong choice.
If MobiFone fits your trip, This MobiFone tourist SIM card guide reveals exactly what to buy and how to get it.
I. Is MobiFone Right for Your Trip?
Choose MobiFone if:
- Your entire trip is in major cities or popular beach destinations
- You’re on a tight budget and city coverage is all you need
- You want a Vietnamese phone number included with your plan
Don’t choose MobiFone if:
- You’re going to Ha Giang, Sapa, Phong Nha, or any remote area
- You’re taking long buses or motorbike rides through countryside
- You need the most reliable connection throughout Vietnam
For most travelers, doing a standard Vietnam tourist circuit — Hanoi, Ha Long, Hoi An, Da Nang, Ho Chi Minh City — MobiFone works well enough. The moment you go off the beaten path, Viettel is the safer choice.

II. MobiFone Tourist SIM Plans
MobiFone offers tourist SIM plans at airports and official stores nationwide. The best-known tourist package is HP2:
| Plan | Data | Calls | Validity | Price |
| HP2 | 8GB total | 40 mins local + international | 30 days | 109,000₫ (~$4.50) |
This is one of the more affordable tourist SIM options in Vietnam — particularly for the 30-day validity. The 8GB total (not per day) is on the lower end for heavy users, so plan accordingly if you stream video or use GPS heavily.
III. Hi Vietnam App — MobiFone’s eSIM Option for Tourists
MobiFone has taken a different approach from Viettel and Vinaphone. Instead of selling eSIM plans through a website, they’ve launched Hi Vietnam — a dedicated app for international tourists that bundles eSIM, calls, and travel services in one place.
How it works:
Download the Hi Vietnam app (iOS or Android) → Register with your passport via eKYC (photo + video call verification) → Receive a free eSIM + 8GB data + 10 minutes of local calls for 24 hours → Buy a paid plan to continue.
Hi Vietnam paid plans:
| Plan | Data | Local calls | Validity | Price |
| HVN3 | 25GB | 30 mins | 3 days | 80,000₫ (~$3.20) |
| HVN7 | 50GB | 70 mins | 7 days | 120,000₫ (~$4.80) |
| HVN15 | 120GB | 150 mins | 15 days | 160,000₫ (~$6.40) |
| HVN30 | 250GB | 200 mins | 30 days | 240,000₫ (~$9.60) |
Pay directly in the app via Visa or Mastercard — no local bank account or cash needed.
Other features of the app include:
- Taxi and hotel booking
- Restaurant and attraction recommendations
- Multilingual interface
- 24/7 customer support in foreign languages
The honest trade-off:
The data amounts are generous and the prices are competitive. But the registration process is more involved than buying a SIM at the airport or scanning a QR code — you need to complete a video call for identity verification, which adds friction. Not ideal if you want to be connected within minutes of landing.
Also worth noting: you need an internet connection to download and set up the app. If you’re arriving without any connectivity, you’ll need to use airport WiFi first.
IV. Where to Buy a MobiFone SIM Card in Vietnam
1. At airports
MobiFone counters are available at major international airports — Noi Bai (Hanoi), Tan Son Nhat (Ho Chi Minh City), Da Nang, and Cam Ranh (Nha Trang). Look for the green MobiFone branding near baggage claim in the arrivals hall.
Bring your passport. Staff will register the SIM on the spot. Expect to pay slightly more than city prices — airport SIMs across all carriers run 30–40% higher than official stores.
Note: Counter hours follow flight schedules and may not be available for very late-night arrivals.
2. At official MobiFone stores
City stores offer the same plans at lower prices and are the better option if you can wait until you’re settled in.
Find your nearest store: mobifone.vn/ho-tro-khach-hang/vi-tri-cua-hang
Opening hours: 8:00 AM – 8:00 PM daily. Bring your passport.
Online via Hi Vietnam app
Download from App Store or Google Play: search “Hi Vietnam” or visit hivietnam.mobifone.vn/tai-app
Best for eSIM-compatible phones. Requires passport eKYC and video verification — plan for 15–20 minutes to complete setup.
V. How to Check Your Data Balance
Once your MobiFone SIM or eSIM is active:
- Dial: 0905# → press call
- App: Download My MobiFone from the App Store or Google Play to track usage and top up
VI. MobiFone Coverage — What to Expect
MobiFone’s 4G network covers all major cities, tourist destinations, and coastal areas reliably. In Hanoi, Ho Chi Minh City, Da Nang, Hoi An, Nha Trang, and Phu Quoc, you’ll get strong 4G at decent speeds.
Disadvantages:
- mountainous regions and rural Vietnam. Ha Giang Loop, Sapa outskirts, Phong Nha countryside, and remote Mekong Delta villages all see weaker MobiFone signal compared to Viettel. If your itinerary includes any of these, consider switching to Viettel.
- 5G is available in major cities but still expanding — most users will be on 4G outside urban centers.
