How do I restrict iPhone setting access? Or prevent someone from changing the settings?

How to Restrict Access to iPhone Settings and Prevent Unauthorized Changes

If you’ve gifted an iPhone to a family member or elderly loved one, you might encounter situations where they inadvertently—or intentionally—modify settings that affect communication, such as toggling airplane mode or disabling cellular data. Managing these settings to ensure consistent usability can be a challenge, especially if you want to prevent unauthorized or accidental changes without compromising the device’s accessibility.

Understanding the Need for Restricting iPhone Settings

In some cases, family members or friends might disable key features like cellular connectivity, either to conserve battery, troubleshoot issues, or simply due to unfamiliarity with device settings. However, if such changes hinder communication, especially in emergencies, implementing restrictions becomes essential.

In your situation, the primary concerns are:
– Preventing the device from being set to airplane mode or disabling cellular data.
– Ensuring your mother-in-law can freely use the device without needing to remember passwords.
– Avoiding security measures that would restrict access for your mother-in-law, yet still maintain control over critical settings.

Utilizing iPhone’s Built-in Restrictions

Apple offers a feature called Screen Time, which allows you to set comprehensive restrictions on device usage, including specific app permissions and setting adjustments.

Steps to Restrict Settings via Screen Time

Set Up Screen Time
Navigate to Settings > Screen Time on the iPhone.
If it’s not already enabled, tap Turn On Screen Time.
Follow the prompts to create a passcode (preferably one only you know).
Configure Content & Privacy Restrictions
Within Screen Time, tap Content & Privacy Restrictions.
Enable the toggle at the top.
You may be prompted to set a passcode separate from the device’s password.
Restrict Changes to Settings
Tap Allow Changes.
Set Account Changes, Passcode Changes, and Cellular Data Changes to Don’t Allow.
Also consider restricting Airplane Mode changes if available.

Note: Not all device settings are fully lockable via Screen Time, especially on older iOS versions. Additionally, restrictions can sometimes be bypassed if the user is knowledgeable, so they aren’t foolproof.
