Background tasks can use mobile data without an obvious action on screen. Photo backups, app updates and video preloading are common examples. A laptop connected by hotspot can add much more. Turn on the phone’s data-saving mode first, then decide which downloads can wait for WiFi.
Turn on the phone’s data-saving setting
On iPhone, open Settings > Cellular or Mobile Service, choose the travel eSIM and turn on Low Data Mode. Apple says this restricts background network use and can pause automatic downloads, backups and updates. Apps decide exactly how they respond, so it is a useful first step rather than a complete block.
On a Google Pixel, open Settings > Network & internet > Data Saver. Samsung normally places it under Settings > Connections > Data usage > Data saver. Android menu names vary, but searching Settings for “Data Saver” is usually quickest.
You can allow an essential app to keep using background data on Android. That is useful if Data Saver delays something you rely on, such as a messaging or transport app.
Download maps before going out
In Google Maps, tap your profile picture, open Offline maps, choose Select your own map, then download the area while you have WiFi. Keep the whole route inside the downloaded area.
Offline Google Maps has limits. Driving directions can work inside the saved area, but live traffic and alternative routes do not. Public transport, cycling and walking directions are also unavailable offline, and map downloads are restricted in some countries.
Apple Maps supports downloaded maps on compatible iPhones. Open Maps, tap your picture, choose Offline Maps, then download the destination area.
GPS itself does not use mobile data, but the map, live traffic and route updates can. A saved map gives you a useful fallback when the signal drops as well as reducing data use.
Pause photo backups and automatic updates
Video clips and full-resolution photos can leave the phone as soon as they are taken. Set iCloud Photos or Google Photos to wait for WiFi during the trip. Do the same for app-store updates and operating-system downloads.
Before changing a backup setting, check how the service describes it. Pausing cellular uploads should leave the files on your phone, ready to upload later. It is not the same as deleting the backup service or its library.
Download music and video on WiFi
Save playlists, podcast episodes and shows before a flight or long train ride. If you do stream over mobile data, choose a lower quality in the app rather than relying on the phone’s system-wide setting alone.
Lowering video quality can save a substantial amount of data. Social apps also preload video, so use their data-saving option where one is available and avoid letting a feed run unattended.
Watch laptops and tablets on your hotspot
A connected laptop may start cloud sync, software updates or media downloads because it sees your phone as WiFi. Pause those tasks before tethering. On a Mac, you can also mark the phone connection as Low Data Mode.
The eSIM hotspot guide explains how to share the connection and what to check when the hotspot control is missing.
Check the balance rather than guessing
With Atli, type data or usage in the WhatsApp or Telegram chat where you bought the plan. The reply shows how much the network has recorded as used and left. Your phone’s own data screen helps identify the app responsible, but the Atli card is the plan balance.
If you do need more data, buy another plan in the same chat. It is added to the Atli eSIM already on the phone, so there is no second installation.
Checked against current Apple Low Data Mode guidance, Google Android and Maps guidance, and Atli’s usage and eSIM lifecycle information, August 2026. App menus and data-saving behavior vary by device and version.
