How much data do I need for a trip?

November 2, 2026

Most travelers use about 3 GB for a week of maps, rides, messages and photos, about 5 GB for two weeks, and 10 GB or more for a month of social and video.

How NUM picks a plan

NUM asks two questions: how long is your trip, and how do you use your phone? Here is the data it looks for:

  • Maps and messages: 1 GB for a week, 2 GB for two weeks, 3 GB for a month.
  • Plus social and photos: 3 GB for a week, 5 GB for two weeks, 10 GB for a month.
  • Lots of video: 10 GB for a week, 20 GB for two weeks, 30 GB for a month.

Five ways to make your data last

  • Download offline maps on wifi before you leave.
  • Turn off automatic app and photo backups while you’re away.
  • Save shows and playlists on wifi.
  • Turn off video autoplay in your social apps.
  • Watch hotspot use, because a laptop can use data far faster than a phone.

Not sure? Choose one size up. It’s easier than running out on day six. See the plans.
