Short answer

For a normal 7-day trip, a moderate plan can fit maps, transport apps, messages, and photos. Video and hotspot use more.

Prepare the first transfer

Save your hotel address and first route before leaving the airport. This reduces the need to search for everything at once.

  • Save the address offline
  • Keep rail or flight details available
  • Install eSIM over Wi-Fi before departure

Data for one week

Maps and messages are usually lighter use than video. Keep some margin if you will share many photos or spend time away from Wi-Fi.

  • Maps and tickets
  • Messages and translation
  • Photos and moderate social media
