Where the 5-day figure comes from
The typical profile assumes half an hour of navigation, an hour of social media and half an hour of browsing each day, plus 30 to 100 MB of messaging and background traffic. That is 160 MB to 835 MB a day, so 5 days comes to 800 MB at the low end and 4.2 GB at the high end. The spread is mostly social media: feeds without video use about 120 MB an hour in the carrier figure we use, while feeds full of short video reach 700 MB an hour.
| Activity (typical profile) | Per day | Over 5 days |
|---|---|---|
| Navigation | 3 MB–5 MB | 13 MB–25 MB |
| Social media | 120 MB–700 MB | 600 MB–3.5 GB |
| Browsing and email | 8 MB–30 MB | 38 MB–150 MB |
| Messaging, email and background apps | 30 MB–100 MB | 150 MB–500 MB |
| Total | 160 MB–835 MB | 800 MB–4.2 GB |
Rates: navigation and social media from Consumer Cellular; browsing and email from AT&T's data calculator; all checked 2026-10-19. Full list on the methodology page.
If you stream or call: the heavy profile
Add half an hour of video, a quarter hour of video calls and an hour of music a day on mobile data, with navigation and social media at the higher setting, and 5 days in Taiwan rises to 3.3 GB to 21 GB. Video streaming alone spans 625 MB to 6.3 GB over the trip, because the Netflix app's Automatic setting uses about 250 MB an hour while HD streaming uses about 2.5 GB. If that is you, plan for 21 GB or an unlimited plan.
Is Taiwan cheap or expensive for mobile data?
