iPhones MMS and SMS Messaging settings
Harriet Chan, co-founder of CocoFinder, counts iPhones MMS and SMS Messaging settings as important settings you should keep on at all times — just in case people trying to communicate with you are not on the same page as you are when it comes to devices.
“The benefit of leaving the setting as you found it is to allow you to send or receive any message that isn’t an iMessage, such as messages and group text messages from people who don’t have iPhones,” Chan says.
To easily enable MMS and SMS Messaging settings, go to Settings, scroll down to Messages and look for the Send as SMS setting, Chan says. “Check if the toggle is on and refrain from ever touching it if it is enabled. Also, avoid changing the MMS Messaging and Group Messaging settings.”
Cross-Site Tracking
Another setting that is best left on is cross-site tracking, according to Daniela Sawyer, Founder and Business Development Strategist of FindPeopleFast.net. “Through advertisements, pop-ups, notifications, advertisers can track you across multiple websites and third party hosts,” Sawyer says. “But the latest version of Safari for iOS 11 lets users prevent such activity by limiting the sites’ ability to monitor their browsing behavior. Therefore, this keeps the user data safe and secured and doesn't let advertisers use it for their purpose.”
To enable this feature, Sawyer advises following the steps below:
*Go to the Settings.
*Tap Safari, and turn on the Prevent Cross-Site Tracking option.
While on the Safari menu option, users can also control advertisements or can permanently block the pop-up ads.
