Block unwanted callers
If you want to check or edit your blocked numbers list, go to Settings>Phone>Blocked List. There you can add new numbers or unblock previously blocked numbers.
Disable Wi-Fi Assist
In addition to adjusting your cellular settings, you should adjust Wi-Fi assist to save your data. This tool allows your cellular signal to stand in for a Wi-Fi signal. It helps with streaming consistency, but if you’re not careful it will also assist you in running up your phone bill. Anyone who regularly goes over her data-usage allowance should turn it off. To do so, click the Settings icon, then click Cellular, then scroll all the way to the bottom for Wi-Fi Assist. Its default position is on (as above)—simply turn it off.

Search within Settings
It can be difficult to find certain items in the Settings app due to the sheer number of options. Finally, Apple has added search functionality. Just pull the screen down once you’re inside Settings. The Search bar is at the very top.
Are you the type to run out of data only 1/3 of the way through your billing cycle? If so, head to Settings>Cellular, and scroll down to where it says “Use cellular data for:”. From there, you can unselect any apps that you don’t want sucking your data when you’re out and about (which leaves you to rely on Wi-Fi when you’re at home or at work for the apps). Any apps you use while commuting should be left on – or you’ll face an annoying popup when you try to access them without Wi-Fi. Our recommendations to leave on? Calendar, Facebook, Instagram, Maps, Mail, Messenger, and Twitter. Disallow everything else.
