How much data do I need for one week in the Asia?

It’ll totally depend on how much time you spend online during your week-long trip in the Asia. If you’re only planning on checking your email, searching for a nearby restaurant, or messaging a friend once in a while, 1-2 GB of data might work for you. For those who rely on navigation apps, want to stream music, and scroll through social media feeds, 3-5 GB might be more suitable. If you’re planning on streaming videos or making video calls throughout your trip, you might need 10 GB or more. Want a more accurate estimate of how much data you’ll need in the Asia based on your internet needs? Use esim.vn data usage calculator to pick the best plan for your trip!

How to use your Asia eSIM

How does a Asia eSIM work?

Three steps: pick a Asia plan, pay, and scan the QR code we email you. No physical SIM swap, and you keep your own number in Asia.

Pick the data plan for your Asia trip

Choose the data and the number of days your Asia trip actually needs — nothing more.

There are 9 Asia eSIM plans right now: 500MB – 20GB, 1 – 30 days, from $3.57 — unlimited-data plans included.

Get your Asia eSIM by email, right after payment

Scan the QR code and follow the install steps. Do it before you fly — installing needs an internet connection.

Step 2: install your Asia eSIM from the emailed instructions.

Land in Asia and you are online

The plan starts counting when the eSIM first connects to a network in Asia — not when you bought it.

Step 3: your Asia eSIM activates on arrival.

What is the difference between an eSIM and a physical SIM?

The main difference between an eSIM and a traditional SIM card is that an eSIM is digital while a SIM card is a physical chip.

Easy to use, affordable, and surprisingly fast — speeds hit about 100 Mbps, more than I expected. Setup was quick and straightforward, coverage stayed stable, and chat support responded fast whenever I needed help. Definitely sticking with this one.

Mr.Hello

Stable, reliable internet connection every time I'm abroad. The price is reasonable and it's simple to use. The support team has also been very attentive whenever I had questions. These days, I use esim.vn's eSIM no matter where I travel ☺️

The website is easy to navigate, which helped me quickly find a data plan that matched my trip. Ordering an eSIM online is really convenient — no matter where I am or which country I'm heading to, I can purchase it in advance.

Super easy to use. I activated my eSIM and was online the moment I landed in Bangkok, while other passengers from my flight were rushing to find SIM card counters in the crowded, stuffy airport.

Comprehensive coverage, fair pricing — the best eSIM I've found for traveling in Asia. Activation is simple: pick a plan on esim.vn, connect, and you're online instantly. Support is always there via chat or email if needed.

esim.vn delivers a seamless experience for every trip. Based on real-world use, most customers highlight a few standout points: quick, hassle-free setup; pricing that's significantly lower than traditional roaming; and stable internet and mobile connectivity for travelers in over 200 countries.
