Airalo Vietnam eSIM review 2026: speed, cost

Airalo Vietnam eSIM is a data-only reseller eSIM that operates on Viettel, Vinaphone, or Mobifone networks depending on signal strength. It is convenient to install before arrival via the Airalo app or QR code — no physical SIM required. However, it lacks a Vietnamese phone number entirely, meaning no SMS reception, no OTP (one-time passwords), and no voice calls.

Pricing wise, Airalo's 7-day 5GB plan typically costs $10–12 USD. By contrast, our local Viettel 7-day eSIM with 5GB/day (35GB total) is $9.90 — more data for a similar or lower price. The Vinaphone 10-day eSIM we sell costs $11.90 and includes a real Vietnamese number with SMS/OTP capability. For travelers who only need data for maps, social media, and Wi-Fi calling, Airalo works fine. But if you need local verification or to be reachable by Grab drivers, the missing number becomes a real problem.

Airalo is a global eSIM marketplace that resells data plans from local carriers worldwide. Their Vietnam plan is not a direct carrier product — it's a data-only package that connects to one of Vietnam's three mobile networks (usually Viettel or Vinaphone) based on real-time signal strength. You activate it through the Airalo app or a QR code before traveling, so you have data as soon as you land.

Plan options for Vietnam include durations of 7, 15, or 30 days with data caps such as 1GB/day, 3GB/day, or total data bundles. Exact plans and prices vary frequently — you should check the Airalo app for current offers. The main takeaway: Airala gives you data connectivity, but no local phone number, no SMS, and no voice.

We have not performed any independent speed tests — but publicly available carrier coverage data is a reliable guide. Viettel claims approximately 99% population coverage, Vinaphone around 97%, and Mobifone about 95%. Since Airalo uses these same networks, its coverage is essentially identical to a local SIM. In major cities like Hanoi, Ho Chi Minh City, Da Nang, and Nha Trang, 4G speeds are generally fast enough for maps, social media, and video calls.

In rural or remote areas such as Sapa, Phu Quoc, or Ha Giang, speeds may be slower and connections may drop to 3G — the same experience you'd get with any local SIM. 5G is available in central districts of large cities, but Airalo does not advertise guaranteed 5G access; most resellers (including Airalo) route data over 4G by default unless otherwise specified. For typical tourist use, performance is adequate, but don't expect consistent high-speed data everywhere.

Airalo's 7-day 5GB total plan is roughly $10–12 USD, and the 15-day 10GB plan around $18–20 USD. Prices fluctuate, so always check the app before buying. By contrast, local eSIMs from Vietnamese providers offer dramatically more data for less money. For instance, the local Viettel 7-day eSIM we sell gives you 5GB per day (35GB total) for $9.90 — that's about $0.28 per GB versus Airalo's roughly $2–4 per GB.

Our Vinaphone 10-day eSIM with 5GB/day and a real phone number costs $11.90, while the Skyfi (Mobifone) 7-day eSIM with 7GB/day is only $8.00. Per GB, local eSIMs range from $0.20 to $0.50, compared to Airalo's $2–4/GB. The data advantage is massive, especially for video streaming, uploading trip photos, or using data-heavy apps. If data quantity is your priority, local eSIMs are far more economical.

Airalo eSIMs are data-only — they do not include a Vietnamese phone number, SMS capability, or voice calls. This means you cannot receive one-time passwords (OTPs) from Vietnamese banking apps like MoMo or VNPay, nor from services like Grab or Shopee that send verification codes. You also cannot receive calls from Grab drivers — though you can message them via the app's chat feature, some drivers prefer to call, especially if they have trouble finding your location.

Without a local number, you have no way to give a contact number to hotels, tour operators, or emergency services (115 for ambulance, 113 for police, 114 for fire). That's a safety and convenience gap. Our Vinaphone eSIM includes a real Vietnamese number with full incoming SMS and call capability — it solves all these issues. For travelers who rely on Grab, need OTPs, or want to be reachable, that phone number is essential.

Choose Airalo if you only need data for maps, Google searches, and Wi-Fi calls, and you already have an alternative way to receive OTPs (for example, roaming on your home SIM). Airalo offers the convenience of a familiar global app and one-time install if you're already using their service in other countries. It's a decent choice for short trips where you don't need local connectivity beyond data.

Choose a local eSIM with a phone number (like our Vinaphone plan) if you need to verify apps with Vietnamese SMS, plan to use Grab heavily and want to be callable, or want a local contact for hotels and tours. Choose a local data-only eSIM (Viettel, Skyfi) if data quantity is your main concern and you don't need a number — these offer far more GB per dollar than Airalo. A hybrid approach also works: keep your home SIM roaming for OTPs while adding a local data eSIM for cheaper internet. Just watch for roaming charges.
