How Long Does 1 GB of Data Last? App-by-App Usage Guide
How much data do maps, WhatsApp, Instagram, YouTube and video calls use? An app-by-app usage table and a simple way to work out how many GB your trip needs.
The most common question when choosing a plan: “How many GB do I need?” The answer depends on how you use your phone. The table below gives approximate values to help you decide.
Data usage by app
| Activity | Approximate usage | With 1 GB |
|---|---|---|
| Messaging (WhatsApp, Telegram) | ~1 MB per 100 messages | Almost unlimited |
| Navigation (maps) | 5–20 MB per hour | 50+ hours |
| Web browsing | ~60 MB per hour | ~16 hours |
| Music streaming | 40–150 MB per hour | 7–25 hours |
| Internet voice calls | ~40 MB per hour | ~25 hours |
| Social media (Instagram, TikTok) | 500–850 MB per hour | 1–2 hours |
| Video calls | 300–800 MB per hour | 1–3 hours |
| Video (SD / HD) | 0.5 / 1.5–3 GB per hour | 2 hours / 20–40 min |
Daily usage profiles
- Light (300–500 MB/day): messaging, maps, occasional browsing.
- Medium (~1 GB/day): all of the above plus social media and music.
- Heavy (2–3 GB+/day): video, video calls, hotspot sharing.
How many GB should you buy?
- Pick your daily usage based on your profile.
- Multiply by the number of travel days.
- Add a 20% buffer for the unexpected.
Example: 7 days of medium use → 7 × 1 GB = 7 GB + 20% ≈ 8–10 GB. For very heavy use, see unlimited or GB plan.
