When purchasing an eSIM for your trip to Japan, many people may wonder, "Is 1GB enough?" "How many days can I use it?"
The actual number of days you can use it greatly depends on whether you are using Google Maps and LINE only, or frequently watching YouTube and Instagram.
In this article, we will explain in detail how much you can use 1GB during your trip to Japan, the data usage by app, and recommended usage methods.
How many days can you use with 1GB?
| Usage Style | Usage Estimate |
|---|---|
| Primarily Google Maps and LINE | About 1 day |
| Using some social media | Half a day to 1 day |
| Watching YouTube | About 1 hour |
| Tethering | Only for a short time |
If you are using Google Maps and LINE while sightseeing, you may be able to use 1GB for about a day. On the other hand, if you watch videos, you may run out of data in a short time.
Data Usage by App
| App | Data Usage Estimate |
|---|---|
| Google Maps | About 5-10MB/hour |
| LINE | About 1-5MB/hour |
| About 100-300MB/hour | |
| YouTube (720p) | About 1GB/hour |
| TikTok | About 800MB-1GB/hour |
While Google Maps and LINE have low data usage, videos on Instagram and YouTube can consume 1GB in a short time.
Recommended Usage Scenarios for 1GB
- Traveling from the airport to the hotel
- Searching for destinations on Google Maps
- Sending messages on LINE
- Using web search a little
- Using the internet in emergencies
1GB is convenient for short-term use, but it may not be sufficient for a trip lasting several days.
Cases Where 1GB is Not Enough
- Watching YouTube
- Spending long hours on Instagram or TikTok
- Using Zoom or Google Meet
- Using tethering
- Saving photos and videos to the cloud
With these types of usage, you may quickly run out of 1GB.
Tips for Extending the Use of 1GB
Since 1GB is a small capacity, you can extend your usage time by being mindful of how you use it.
- Use Wi-Fi at hotels and cafes
- Save Google Maps for offline use
- Watch videos in Wi-Fi environments
- Turn off automatic backup for photos and videos
- Stop background data usage for unnecessary apps
By being aware of these tips, you may find that 1GB is sufficient for map searches and messaging while sightseeing.
Which should you choose: 1GB, 3GB, or 5GB?
| Capacity | Recommended Usage |
|---|---|
| 1GB | Google Maps, LINE, emergency use |
| 3GB | 1-2 days of sightseeing |
| 5GB | Social media posting or trips of about 3-5 days |
For a trip to Japan, 1GB is suitable for minimal use. If you want to use it with peace of mind, it is recommended to choose 3GB or more.
