Question 1

How much data do I need for a week?

Accepted Answer

For a one-week trip, 3–5 GB is usually enough for maps, messaging and light social media use. Choose around 10 GB if you share photos or use social media every day, and 20 GB or more if you regularly stream video, make video calls or use a hotspot.

Question 2

How much data does Google Maps use?

Accepted Answer

For regular navigation, allow roughly 5–20 MB per hour after the route and map area have loaded. Searches, satellite view, Street View, photos and live traffic can use more data. Downloading an offline map over wifi before you leave helps reduce your usage.

Question 3

Do WhatsApp video calls use a lot of data?

Accepted Answer

A WhatsApp video call can use roughly 0.3–1 GB per hour. The actual amount depends on the connection and video quality. Audio-only calls use much less data, and turning off your camera also reduces usage.

Question 4

Why does the estimate include a 20% buffer?

Accepted Answer

Actual usage can be higher than planned because of route changes, slow wifi, automatic uploads, background activity and changes in video quality. The 20% buffer gives you some room for those differences without immediately needing a larger plan.

Question 5

Can I just use wifi instead?

Accepted Answer

You can use reliable wifi for large downloads, backups and streaming. However, wifi may not be available while you are travelling between places. Keep enough mobile data for maps, tickets, transport, messages and bookings when you are away from your accommodation.
