Landing in Vietnam without reliable mobile data means struggling with airport taxi scams, getting lost in Hanoi's Old Quarter, or missing that important Grab ride. We've lived in Vietnam for 3+ years and tested every major eSIM provider across the country-from Sapa's mountains to Phu Quoc's beaches.

The verdict? Not all eSIMs are created equal. Some have terrible coverage outside major cities, others throttle your speeds after just 1GB, and many are overpriced compared to what locals pay.

This guide reveals the 4 best eSIMs for Vietnam that actually work, with real pricing, and our honest recommendations based on extensive testing. Skip the airport SIM card queues and land already connected.

Sim Local

Sim Local partners with local networks for priority speeds and even includes calls/texts in some plans. Super useful for messaging with hotels or family without extra apps.

We've tested it throughout Vietnam and it's always been reliable all the way from the Northern mountains of Sapa to the tropical beaches of Phu Quoc.

Try 5GB ($11.25) for short trips or 10GB ($18.25) for longer ones.

If you need more data they guarantee at least 10GB of high-speed data per day with their unlimited plans, while other eSIM companies normally slow down your connection after only a few GB. This means you can watch our videos 😉, send pictures home, or stream Netflix without buffering, keeping your trip stress-free.

They even have physical stores in a bunch of airports worldwide making it super easy to get connected if you prefer in-person setup.

Also, their 24/7 customer support via email, phone, and WhatsApp, plus a full refund promise if the eSIM doesn't work a nice little bonus!

Saily keeps it simple with the amount of plans they offer, with only 5 to pick from. Go with 5GB/30d ($11.99) for quick visits or if you don't use much data. We recommend their 10GB/30d ($19.99) for extended stays.

Choosing Your eSIM

Trip Length

Planning a quick Hanoi weekend or a month-long Vietnam adventure? For short trips (1-7 days), a 1-5GB plan covers light browsing, like checking maps or booking Grab. We use 3GB for quick city breaks, like a Da Nang getaway, and it's plenty for basic apps.

Longer stays (7-30 days) need 10GB or more, especially if you're doing a North to South tour. Sim Local's Find My Plan tool helps match your trip length and requirements to the right data amount, saving you from overpaying.

Data Needs

Think about how you'll use your phone. Light users, like us when we're just navigating Hanoi's Old Quarter or messaging hotels, can stick with 1-5GB for emails, maps, and WhatsApp. A 3GB plan keeps costs low for these basics.

If you're streaming videos, posting Instagram reels from Ha Long Bay, or video-calling home, aim for 10GB+ or unlimited plans.

Extra Features

Some eSIMs offer perks that make your trip smoother. Sim Local includes calls/texts in select plans, perfect for confirming bookings without needing additional apps, handy for us when calling local guides.

FAQ: Vietnam eSIM Basics

  • Is my phone eSIM-compatible? Most phones post-2018 (iPhone XS+, recent Androids) support eSIMs. Check your settings or manual.
  • Will these work everywhere in Vietnam? All cover 99% of tourist spots, from Hanoi to Phu Quoc.
  • Can I buy before landing? Yes, all activate via apps pre-flight for instant use.
  • Do plans include calls? Sim Local offers calls/texts in select plans; others are data-only, use WhatsApp or similar apps for calls.
