How to Check Viettel Data Usage in Vietnam (Easy Guide for 2025)

Viettel tourist eSIMs are a simple way to stay online throughout your trip in Vietnam. They’re data-only, so instead of checking a traditional phone “balance,” what really matters is how much high-speed data you still have for the day. This guide keeps things straightforward and traveler-friendly, especially if it’s your first time using a Vietnamese eSIM.

📱 Why It’s Useful to Check Your Daily Data

• See how much high-speed data you’ve used on busy travel days
• Make sure your eSIM is working normally after landing
• Avoid running out of fast data when you’re using maps or booking rides
• Monitor usage when sharing hotspot with friends or family

🔍 The Easiest Ways to Check Viettel Data Usage

These tourist eSIMs include 5GB of high-speed data per day. When you reach that amount, the speed slows until the next midnight reset. Here are the methods that actually work for this type of eSIM:

1️⃣ Use USSD *098#

• Open your phone dialer
• Enter *098# → press Call
• Your current data package will appear on the screen

Some international phones display USSD differently. If you don’t see full details, use your phone’s built-in data tracker.

2️⃣ Check Your Phone’s Data Tracker

• iPhone: Settings → Mobile Data → Current Period
• Android: Settings → Connections → Data Usage → Mobile Data Usage

This works well if you’re sharing hotspot or using data-heavy apps like maps or photo backups.

3️⃣ Quick Restart if Speed Feels Slow

Your high-speed allowance resets at midnight. If you’ve already used your 5GB and the speed doesn’t refresh, restarting your phone usually helps update the new cycle.

🌄 A Small Note for Mountain Routes

Trips to Sapa, Ha Giang, Cao Bang, or northern passes often rely heavily on mobile data for navigation. Viettel has the widest coverage in these areas, but it’s still a good habit to check your remaining high-speed data before long rides.

📞 When You Might Actually Need a Phone Number Instead

A data-only eSIM works for most travelers—maps, Grab, WhatsApp, translation, hotel check-ins, everything essential. But a few situations do require a Vietnamese phone number:

• Receiving bank or app OTPs (Shopee, Zalo, Lazada, Airbnb)
• Drivers or hotels needing to call you directly
• Business trips where a local number is expected

If that’s your case, you may prefer an option that includes a local number: Vietnam eSIM with Phone Number.

🔧 Troubleshooting Common Issues

• *098# shows incomplete info: Toggle Airplane Mode or restart the device
• Sudden slow speed: You likely reached your daily 5GB; it resets at midnight
• Pages load slowly even with data: Turn off any active VPN, then switch between 4G/5G

🚗 Arrival Tip for First-Time Travelers

If you’re landing late or just want a smoother arrival, many travelers choose to arrange their airport ride in advance. It removes the stress of searching for a taxi counter or dealing with long queues after immigration. You can see available options here: Vietnam airport pickup service.
