Upload Speed Matters
Most eSIM speed tests focus on download. For photographers, upload speed determines how fast photos reach Instagram and cloud storage.
| Provider | Avg Upload (our tests) | Best For |
|---|---|---|
| Saily → | 38 Mbps | Fastest uploads. 15 MB photo in <1 second. |
| Ubigi → | 28 Mbps | Good uploads + best rural coverage. |
| Airalo → | 22 Mbps | Solid uploads, best app for managing data. |
All three are fast enough for photo uploads. Saily edges ahead for speed.

Pro Tips for Photographers in Japan
1. Disable auto cloud backup on cellular. Back up manually at hotel WiFi. This saves 500+ MB per day.
2. Upload Instagram at the hotel/café. Queue posts in the app, upload on WiFi.
3. Shoot RAW? Never upload RAW files on cellular. One RAW file = 25-50 MB.
4. Use Google Photos "Storage Saver" mode — compresses to 16 MP, uses 1/3 the data.
5. Best light in Japan: Golden hour at temples (5-7 AM, 4-6 PM). Arrive early — no crowds for clean shots.
