How many GB do I need for a trip?
Short answer: with normal travel usage you burn 1 to 3 GB per day — that's 10 to 30 GB in 10 days. That's why the "cheap" 3-5 GB plans end up expensive: they run out mid-trip. The detailed math:
How much each thing uses (typical travel day)
| Usage | Approx. consumption |
|---|
| Google Maps navigating 2-3 h | 50-150 MB |
| WhatsApp (text + voice notes + photos) | 100-300 MB |
| 30-min video call | 300-500 MB |
| Instagram/TikTok 1 h | 600 MB - 1.5 GB |
| Photos/videos syncing to the cloud | 500 MB - 2 GB |
| Music streaming 2 h | 100-200 MB |
| Uber, translator, search, e-mail | 100-200 MB |
Realistic total: 1.5 to 3 GB/day. With video on social or laptop hotspot, quite a bit more.
So, which plan should I buy?
- 5 GB for 10 days = 500 MB/day: only if you live on Wi-Fi and use the phone for emergencies.
- 10 GB for 10 days = 1 GB/day: tight, with the counter always on your mind.
- Unlimited: the phone like at home — maps without fear, photos syncing on their own, video calls with the family. With VoaSim it starts at USD 1.79/day, often less than 10-20 GB by volume at other brands.

Can I travel on 3 GB?
It's possible, living on Wi-Fi and keeping data as backup. One day of maps + photos + social can eat 2 GB alone.
Does laptop hotspot use a lot?
Yes: a laptop consumes several times more than a phone (updates, cloud, HD video). On a per-GB plan, it's the silent killer.
How do I use less data while traveling?
Download offline maps, lower photo-upload quality, disable video autoplay. With unlimited, none of that is necessary.
