During your trip to Japan, there may be times when you need to contact family and friends via WhatsApp or send messages to hotels and tour companies. Therefore, you might be wondering, "How much data does WhatsApp use?" and "Is 3GB or 5GB of eSIM enough?"
WhatsApp is a relatively low-data app when used primarily for text messaging. However, if you frequently make voice or video calls or send and receive photos and videos, the required data capacity will increase.
In this article, we will explain the differences in data usage for each WhatsApp feature, recommend eSIM capacities for your trip to Japan, and provide tips on how to save data.
How much data does WhatsApp use?
The data usage of WhatsApp varies significantly depending on the features you use. If you are only sending and receiving text messages, it does not require much data.
On the other hand, voice and video calls transmit data in real-time, so the longer you use them, the more data you will consume.
| Usage Type | Data Usage Trend |
|---|---|
| Text Messages | Very Low |
| Sending and Receiving Photos | Low to Moderate |
| Voice Messages | Low |
| Voice Calls | Moderate |
| Video Calls | High |
| Sending and Receiving Video Files | High |
If you only use messaging and short voice calls during your trip, WhatsApp is unlikely to consume a large amount of data.
How to Use WhatsApp During Your Trip to Japan?
In addition to contacting family and friends, you may use WhatsApp in the following situations during your trip to Japan:
- Sharing meeting points with travel companions
- Contacting hotels or accommodations
- Sending messages to tour companies or guides
- Sharing location information or links to tourist spots
- Sending photos and videos during your trip
Especially for meeting up or confirming reservations, having an eSIM that allows you to connect to the internet while on the move is reassuring.
How Many GB Should You Have for Peace of Mind During Your Trip to Japan?
If you are only using WhatsApp, you typically do not need a large data plan. However, if you also use Google Maps, social media, and video services, consider the total data usage for your trip when making your choice.
| Usage Style | Recommended Capacity |
|---|---|
| Messaging Focused | 3GB |
| Sending Photos and Short Voice Calls | 5GB |
| Including Video Calls | 10GB |
| Long Video Calls and Sending Videos | Unlimited |
While 3GB is often sufficient for just WhatsApp messaging, if you use maps and social media daily during your trip, choosing more than 5GB will give you more flexibility.
How to Save Data on WhatsApp
- Use video calls in Wi-Fi environments like hotels
- Send long video files when connected to Wi-Fi
- Review the automatic download settings for photos and videos
- Turn off automatic saving for unnecessary media
- Choose an eSIM capacity that matches your travel days and usage purposes
WhatsApp's automatic download settings for photos and videos can lead to increased data usage without you realizing it. It's a good idea to check your mobile data settings before your trip for peace of mind.
Points to Consider When Using WhatsApp
To use WhatsApp comfortably during your trip to Japan, it is important to manage your data usage according to your needs. The following points can help you stay connected while keeping data usage low.
- Use Wi-Fi at hotels or cafes for video calls
- Send videos and large numbers of photos when connected to Wi-Fi
- Review the automatic download settings for media
- Reduce unnecessary background data usage
- Consider other apps you will use during your trip when choosing an eSIM
WhatsApp requires little data if you only use text messaging. However, be cautious as data usage can significantly increase with long video calls or sending and receiving video files.
Frequently Asked Questions
Is 3GB enough for just WhatsApp?
If your usage mainly consists of sending and receiving messages and short voice calls, 3GB may be sufficient. However, if you also use Google Maps and social media, it is safer to choose more than 5GB.
Does WhatsApp messaging use a lot of data?
No. The data required for sending and receiving text messages is very low, and normal usage does not significantly consume data.
Is WhatsApp voice calling data-intensive?
Voice calls can be used with relatively low data usage. However, if you continue a call for a long time, data usage will gradually increase.
How much data does WhatsApp video calling use?
Video calls consume more data than messaging or voice calls because they transmit video. If you plan to use them for long periods during your trip, using Wi-Fi or opting for an eSIM plan with more than 10GB is recommended.

If your main usage is WhatsApp messaging and Google Maps, 3-5GB is recommended. If you also use video calls and social media frequently, consider 10GB or more. For those who want to use data without worry, an unlimited plan is advisable.
Can I use WhatsApp on the subway or JR?
