How much data do I need?

Most travellers overbuy. This estimates what a trip actually consumes, using the per-hour figures below — change any of them if your habits differ.

Days away

Maps and navigation (hours/day) 5 MB/hour

Social and messaging (hours/day) 90 MB/hour

Web and email (hours/day) 60 MB/hour

Music streaming (hours/day) 80 MB/hour

Video streaming (hours/day) 900 MB/hour

Video calls (hours/day) 400 MB/hour

Estimated total—

Figures are typical rather than exact; video in particular varies by more than tenfold with resolution. Add roughly 20% headroom, and prefer a plan that supports top-up over buying the next size up.
