Viettel vs Vinaphone vs Mobifone: Best Vietnam eSIM

Vietnam’s mobile market is dominated by three state-owned carriers: Viettel, Vinaphone, and Mobifone. Viettel has the largest subscriber base and the widest geographical coverage, claiming roughly 70% population reach. Vinaphone runs a close second, with strong urban and coastal infrastructure. Mobifone is the smallest of the three, but remains reliable in major cities and tourist hubs. All three networks support 4G/LTE, and 5G is being rolled out in city centers — though it is not yet ubiquitous.

When you buy an eSIM from us, you’re getting a direct connection to the carrier’s network. For Mobifone coverage specifically, we offer plans from Skyfi, a trusted reseller that operates on the Mobifone network. That means you get Mobifone’s infrastructure without needing to sign up through the carrier directly. Prices vary by carrier and duration, with Skyfi plans generally being the most affordable per day.

Viettel is the go‑to for travelers heading off the beaten path. Its network reaches deep into mountainous provinces like Sapa, Ha Giang, and the Central Highlands, and it maintains reliable service along major highways and even inside some road tunnels. For trekkers and anyone visiting national parks, Viettel’s consistent signal in remote areas is a major advantage.

Vinaphone performs very well in cities and along the coast. Hanoi, Ho Chi Minh City, Da Nang, Nha Trang, and Phu Quoc all have strong Vinaphone coverage. It’s an excellent choice for tourists who stick to urban sightseeing, beach resorts, and well‑traveled routes. Mobifone’s network (accessed via Skyfi plans) is also solid in downtown areas and tourist corridors, though it may occasionally drop to 3G in less dense suburbs or rural spots. In the Red River and Mekong deltas, all three carriers offer generally good coverage.

We offer eSIMs with different data allowances across the three carriers. Viettel and Vinaphone plans come with 5GB of high‑speed data per day, while Skyfi (on the Mobifone network) provides 7GB per day. All plans are prepaid — no contracts, no hidden fees — and delivered as a QR code for instant installation.

Pricing is straightforward: Viettel 7‑day plan is $9.90, 15‑day $12.90, and 30‑day $18.90. Vinaphone offers a 10‑day plan at $11.90, 15‑day at $13.90, and 30‑day at $18.90. Skyfi plans are the cheapest per day: 7 days for $8, 10 days for $10, and 15 days for $11. If your trip is under a week, any carrier’s 7‑day plan works, but Skyfi at $8 is the lowest entry point.

During normal use, 4G speeds on all three carriers are sufficient for maps, social media, video calls, and streaming music. In city centers, you can expect a smooth experience. In remote or mountainous areas, speeds may drop (often to 3G or slower 4G), but Viettel generally maintains the most consistent connection in those zones.

Our eSIMs provide full‑speed data until the daily cap is reached — there is no throttling before that point. After the daily cap, the plan either stops data (hard cap) or reduces speed to 128kbps, depending on the specific product. We list the exact policy on each product page. 5G is available in limited city zones, but all our current plans are 4G‑capable; if you happen to be in a 5G area with a compatible device, you’ll still only get 4G speeds on these plans.

If your itinerary includes trekking in Sapa, Ha Giang, or Phong Nha, Viettel is the safest bet. The 15‑day plan at $12.90 or 30‑day at $18.90 gives you peace of mind in areas where other networks are patchy. For city‑only visitors or coastal resort stays, Vinaphone (10‑day $11.90 or 15‑day $13.90) offers reliable coverage at a fair price, while Skyfi’s 10‑day plan at $10 is the best value if you’re sticking to urban hubs.

Heavy data users who stream video or tether often should consider Skyfi’s 7GB/day allowance — it gives you more high‑speed data each day than the 5GB/day plans from Viettel or Vinaphone. For a short trip under 7 days, Skyfi at $8 is the cheapest option. Ultimately, the choice depends on your destinations and how much data you consume.

For overall coverage — especially in rural and mountainous areas — Viettel is the clear winner. If you intend to explore beyond the tourist trail, choose Viettel. For the best value per gigabyte while staying in cities and tourist hubs, Skyfi (Mobifone network) plans offer the lowest daily price with the highest per‑day data cap. Vinaphone strikes a solid balance: good coverage in urban and coastal destinations, competitive pricing, and the added benefit of a real Vietnamese phone number for receiving calls and SMS (useful for OTPs and Grab driver contact).

Our portfolio covers all three options — pick the one that matches your itinerary and budget, and you’ll be connected from the moment you land.
