How to reduce background data use on iPhone
iOS Configuration Guide
Apps use data in the background without you noticing: email checks, backups, updates. On a travel plan with a fixed amount of data, limiting this makes your data last longer.
Turn on Low Data Mode for the eSIM
- Open Settings and tap Cellular.
- Tap your eSIMtime plan.
- Turn on Low Data Mode (on some iPhones: Data Mode > Low Data Mode).
Limit Background App Refresh
- Open Settings and tap General.
- Tap Background App Refresh.
- Choose Wi-Fi only or Off, or turn it off for individual apps.
What changes
Your iPhone will use very little data in the background. Emails may not arrive automatically and updates wait until you are on Wi-Fi. Apps you open still work as usual.
