Low Data Mode iPhone settings help reduce background internet use, but you can switch it off when you need normal syncing and downloads. For cellular data, open Settings and find your line's Data Mode or Cellular Data Options. For Wi-Fi, open the connected network's settings and disable Low Data Mode.
Low Data Mode iPhone: How to Turn It Off
The exact path depends on the selected line and whether your carrier uses LTE/4G or 5G menus. Apple's official Low Data Mode instructions distinguish the options, so identify your active data line before making changes. Low Data Mode can be controlled separately for cellular data and Wi-Fi.
| Connection | Where to find it | How to switch it off |
| LTE/4G | Settings > Cellular > Cellular Data Options | Turn Low Data Mode off |
| 5G | Settings > Cellular > Cellular Data Options > Data Mode | Select Standard or another non-Low Data Mode option |
| Dual SIM | Settings > Cellular > select the relevant number | Turn Low Data Mode off for that line |
| Wi-Fi | Settings > Wi-Fi > information button next to a network | Turn Low Data Mode off for that network |
For 5G cellular plans
- Open Settings > Cellular (or Mobile Data).
- Tap Cellular Data Options > Data Mode.
- Choose Standard instead of Low Data Mode. Your available choices may differ by carrier and iOS version.
For LTE or 4G plans
- Open Settings > Cellular > Cellular Data Options.
- Turn Low Data Mode off if the switch appears. On some devices, select Data Mode and then Standard.
For Dual SIM or a travel eSIM
- Open Settings > Cellular.
- Select the line you want to change, such as your home SIM or travel eSIM.
- Open the line's data options and disable Low Data Mode or select Standard.
The setting is line-specific where the interface provides separate options. Check which line is actually selected for cellular data before changing it.
How to Turn Off Low Data Mode on Wi-Fi
Low Data Mode can also be enabled for individual Wi-Fi networks. Changing the cellular setting will not necessarily change the setting on a hotel or airport Wi-Fi network.
- Open Settings > Wi-Fi.
- Tap the information (i) button next to your connected network.
- Turn Low Data Mode off.
Apple's Wi-Fi settings reference confirms that the option is managed per network.

What Low Data Mode Does on iPhone
Low Data Mode asks iOS and compatible apps to reduce background network activity. It does not turn mobile data off, guarantee a fixed amount of savings, or prevent every app from transferring data.
Apple identifies several concrete changes: Background App Refresh is disabled; App Store automatic downloads and updates stop; iCloud Photos updates and automatic iCloud backups pause; and FaceTime may optimize video bitrate. Music streaming quality and Podcasts downloads may also change. Third-party apps can respond differently, so the feature does not guarantee that streaming, messaging, or downloads will use a particular amount of data.
| Setting | Low Data Mode On | Low Data Mode Off |
| Background transfers | May be reduced or deferred | Normal app and system rules apply |
| Automatic updates | Some may be postponed | May proceed when other conditions allow |
| Video and media | Some services may use less data | App quality settings still apply |
| Internet access | Remains available | Remains available |
| Best use | Metered or limited allowance | Unrestricted network or needed syncing |
When to Keep Low Data Mode Enabled
Low Data Mode is most valuable when avoiding background transfers matters more than immediate syncing. Keep Low Data Mode enabled when a mobile allowance is limited, you are sharing a metered connection, or you want to reduce unexpected background transfers during a trip. It is especially useful while relying on a small travel eSIM data package.
Turn it off when you need cloud photos to sync, backups or automatic downloads to resume, or apps to operate normally on a trusted unlimited connection. Low Power Mode is a different setting: it focuses on power use rather than measuring or restricting a data allowance. If you share your iPhone's connection as a hotspot, also set data-saving rules on the connected laptop or tablet, since its downloads can still consume the shared allowance.
Why Low Data Mode May Be Missing or Not Working
If the option is missing, check the selected cellular line, your carrier's settings, and whether the phone is using LTE or 5G. Apple notes that available menus can vary by carrier and plan.
If data use remains high, check Settings > Cellular to identify apps consuming data. Streaming, video calls, downloads, and hotspot-connected devices can still use substantial data even when Low Data Mode is enabled.
If the toggle is off but photos still are not syncing, check whether the phone is online, whether iCloud Photos has another pause reason, and whether Low Power Mode or app-specific restrictions are active. For broader troubleshooting, compare iPhone cellular data fixes with iPhone eSIM setup steps. Avoid resetting network settings merely because an app consumes more data than expected.
Using Low Data Mode With a Travel eSIM
Travelers often need mobile data for airport transfers, navigation, train tickets, and accommodation check-in. Low Data Mode can help reserve a limited allowance for those tasks, although reception may still weaken underground, on remote roads, or inside large buildings.
An Eskimo Global eSIM may suit multi-country travel where destinations are included in the selected plan. Eskimo's overall service footprint spans 175 countries and regions, but each plan has its own coverage list. Its no-expiry fixed-data plans can be helpful if you want unused qualifying data to remain available for later trips rather than expire on a short countdown.
New users can also claim a free 500MB Global eSIM.
FAQs
Does turning off Low Data Mode use more data?
It can. Background tasks and downloads may resume, but actual usage depends on your apps, network, and settings.
Does Low Data Mode turn off 5G?
No. It controls data-use behavior, not whether 5G is enabled. Network mode is managed separately.
Why is Low Data Mode on for Wi-Fi but off for cellular?
Wi-Fi and cellular settings are separate, so a particular Wi-Fi network can use Low Data Mode even when your cellular line does not.
Should I turn off Low Data Mode on my travel eSIM?
Keep it on if conserving a capped allowance matters. Turn it off temporarily if an important background download or sync is being deferred.
Conclusion
To turn off Low Data Mode on iPhone, change the setting for the specific cellular line or Wi-Fi network you are using. The menu may appear directly under Cellular Data Options or inside Data Mode, depending on the plan. Keep Low Data Mode enabled when conserving a limited travel allowance matters, and disable it when you need ordinary syncing and downloading. If usage still seems unusually high, review the apps consuming data before changing unrelated network settings.
