How Much Data Do You Really Need When Travelling in Asia?
When choosing an eSIM for travelling within Asia, you’ll no doubt be questioning how much data you actually need. Many people either buy far too little and run out, or far too much and pay more than necessary.
The reality is that data use depends less on where you travel and more on how you travel.
This guide breaks down typical data usage, what activities consume the most data, and how to choose between fixed and unlimited plans for a trip through Asia.

What do travellers use data for?
Most travellers use mobile data for the same everyday tasks they use at home, including:
-
Maps and navigation
-
Messaging apps like WhatsApp or Messenger
-
Ride-hailing and transport apps
-
Translation tools
-
Search for restaurants and attractions
-
Booking accommodation or activities
-
Uploading photos and videos
These small tasks add up quickly, especially when you are out exploring all day.
How much data do common activities use?
This is a rough guide to what everyday travel activities consume:
| Activity | Approximate data use |
| Google Maps navigation | 5–10 MB per hour |
| Messaging apps (text and photos) | 10–50 MB per day |
| Browsing websites | 50–100 MB per hour |
| Social media scrolling | 100–300 MB per hour |
| Uploading photos | 50–200 MB per session |
| Video calls | 300–500 MB per hour |
| Streaming video | 1–3 GB per hour |
These are averages. Real use varies by app and behaviour.
What does this mean for a typical day of travel?
A fairly normal sightseeing day might include:
-
Using maps to get around
-
Sending messages and photos
-
Looking up restaurants and transport
-
Browsing attractions
That can easily reach 300–800 MB per day without any video streaming.
Travellers who:
-
Use social media heavily
-
Make video calls
-
Upload photos and videos
-
Rely on apps constantly
can exceed 1–2 GB per day without realising it. There have been days when I have burnt through my whole 2GB allowance and not realised until my data is disconnected.
Fixed data or unlimited data: which should you choose?
This is where many travellers get stuck.
Fixed data plans
A fixed data plan gives you a set amount, such as 5GB or 10GB, to use over your trip.
They work well if you:
-
Mostly use maps and messaging
-
Spend time on Wi-Fi
-
Travel at a relaxed pace
-
Want to keep costs lower
For example, a 10GB plan can comfortably support a one- to two-week trip with light to moderate use.
Unlimited data plans
Unlimited plans are designed for heavier or more unpredictable usage.
They are better suited if you:
-
Use your phone constantly
-
Work while travelling
-
Rely on mobile data for navigation and bookings
-
Stream, upload, or video call
-
Visit multiple countries and stay active on the go
For many travellers in Asia, especially those on busy itineraries, unlimited data removes the need to think about usage at all.
How Pocket Roam plans fit into this
Travel-focused providers like Pocket Roam offer both fixed data and unlimited eSIM plans for Asia and individual countries.
This allows travellers to:
-
Choose a lower-cost fixed plan for light use
-
Upgrade to unlimited data for heavy or flexible travel
-
Pick country-specific or regional coverage depending on the trip
Matching your plan to how you actually use your phone often saves money and prevents running out of data mid-trip.
A simple way to estimate your data needs
Ask yourself:
-
Do I rely on my phone for navigation all day?
-
Will I be uploading photos or videos regularly?
-
Will I be working or making video calls?
-
Will I be visiting multiple countries?
If you answer “yes” to more than one, unlimited data is usually the safer choice.
If your use is mostly maps and messages, a fixed data plan is often enough.
Final thoughts
There is no single right answer for how much data you need when travelling in Asia. It depends on how you move, how connected you like to be, and how flexible your plans are.
Understanding your own habits is the best way to choose the right eSIM and avoid either running out of data or paying for more than you need.
