Tips to save data while travelling
Make your eSIM plan last longer with these simple habits.
Download maps offline
Save Google Maps areas before your trip to avoid using data for navigation.
Lower streaming quality
Switch to SD on YouTube and Netflix — it uses 4x less data than HD.
Use Wi-Fi when available
Connect to hotel and cafe Wi-Fi for heavy downloads and video calls.
Disable auto-updates
Turn off automatic app updates and cloud photo backups on mobile data.
Use messaging over calls
WhatsApp messages use a fraction of the data that voice or video calls do.
Preload content
Download Spotify playlists and Netflix shows on Wi-Fi before heading out.
