Viettel prepaid data plans for tourists – prices & coverage

Viettel's prepaid data eSIMs for tourists come in three convenient durations: 7 days at $10, 15 days at $11, and 30 days at $15. Each plan provides 5GB of high-speed data per day, which resets at midnight Vietnam time. These plans are native Viettel connections — not reseller or MVNO — so you get full priority on Viettel's 4G and 5G networks.

The eSIM activates automatically when your phone first connects to a Viettel network in Vietnam. You install the QR code before your trip (requires Wi-Fi), and the clock starts ticking upon arrival. Daily data caps are generous: 5GB per day is enough for navigation, social media, messaging, and occasional video calls. If you run out, speeds are reduced but basic connectivity remains.

Viettel operates the most extensive network in Vietnam, covering not only major cities like Hanoi, Ho Chi Minh City, and Da Nang but also remote mountainous areas (Sapa, Ha Giang) and popular islands (Phu Quoc, Con Dao). In urban centers, you can expect strong 4G+ and 5G signals with consistent speeds. Highways and off-the-beaten-path tourist spots generally enjoy reliable Viettel signal, making it the top choice for adventurous travelers.

Viettel publicly states that its network covers approximately 99% of Vietnam's population. While we haven't conducted our own drive tests, anecdotal reports from travelers confirm that even in rural Mekong Delta villages and highland passes, data connectivity remains usable for maps and messaging. No carrier covers every square meter, but Viettel's footprint is the broadest among Vietnamese operators.

Purchasing a Viettel eSIM is straightforward: choose your preferred plan (7, 15, or 30 days) and complete payment. The QR code is delivered via email shortly after. You must install the eSIM profile on your phone before departing for Vietnam — this requires an internet connection. Once installed, the eSIM remains inactive until your phone connects to Viettel's network upon arrival in Vietnam.

Compatible devices include iPhone XS and newer (excluding mainland China, Hong Kong, and Macau variants), Samsung Galaxy S20 and newer, Google Pixel 3+, and most recent Android phones from OnePlus, OPPO, Xiaomi, and Huawei. Dual-SIM functionality works: keep your home SIM active for calls and SMS while using Viettel eSIM for data. You don't need to provide personal ID for purchase — it's a prepaid tourist product.

Vinaphone and Mobifone also offer prepaid eSIM plans for tourists. Vinaphone's 10-day plan costs $12 for 5GB/day, and its 30-day plan is $16. Mobifone (often sold as Skyfi) is the cheapest option: a 7-day plan costs just $8 with 7GB/day. However, Mobifone's network can be slower in crowded areas, making it less ideal for heavy streaming or video calls.

For trips that focus on off-the-beaten-path destinations like Sapa, Ha Giang, or rural Mekong, Viettel is the recommended choice due to its superior rural coverage. In cities, both Viettel and Vinaphone perform similarly, but Viettel generally holds an edge in speed during peak hours. Multicountry eSIMs from global resellers (e.g., Airalo, Holafly) offer the same underlying networks at higher prices — a local eSIM is more economical for Vietnam-only trips.

5GB per day covers maps, messaging, social media, and occasional video calls comfortably. Tethering (using your phone as a hotspot) is allowed, but heavy usage may result in throttling; no official throttle limit is published. For light laptop work, hotspot works fine, but avoid large downloads or HD streaming unless you have extra data.

5G is available in major cities like Ho Chi Minh City, Hanoi, and Da Nang — you'll need a compatible 5G phone to use it. Data resets daily at midnight Vietnam time, so if you arrive late in the day, you still get a full day's allocation. Always carry a backup offline map (e.g., Google Maps offline) just in case you lose signal in very remote spots.

iPhone: eSIM is supported on iPhone XS, XR, and all newer models — but only those sold outside mainland China, Hong Kong, and Macau. Samsung: Galaxy S20 series, Note20, S21/S22/S23/S24 series, Z Flip/Fold series all work. Google Pixel 3 and newer (excluding 3a, 4a) are compatible. Other brands: OnePlus 8 and newer, OPPO Find X3 and newer, Xiaomi 12 and newer, Huawei P40 and newer — check your specific model for eSIM capability.

iPad models with Wi-Fi + Cellular (from iPad Pro 3rd gen, iPad Air 3rd gen, iPad 7th gen) and Apple Watch with GPS+Cellular also support eSIM. If you're unsure about your device, consult the manufacturer's eSIM support list or contact the seller before purchase. Remember: phones from China mainland (any brand) often lack eSIM hardware — a physical SIM alternative may be needed.
