I’ve been closing down “cell” apps in settings—what else?

[ConservativeMind]

Well, your “cell data” is using your Verizon router which uses cell data of its own. Do you have a separate cell data allotment from your Verizon wireless router? Anything you stop from using cell data will use your Verizon router data, so please understand this. We are simply playing with balancing two separate data limits (your phone and your Verizon wireless router).

On to more to help.

Please implement the following items from the slideshow afterward:

2. Stop your iPhone from tracking you
3. Prevent apps from uploading your data
6. Limit apps from tracking your location in the background
13. Prevent iPhone location-based tracking
14. Install a content blocker
15. Limit advertisers tracking your location, data

You can do the other slides’ recommendations, too, but those won't effect any change on data use limits.

How did your data use trimming work for you?

Do you have separate data limits for your device on the cell data network, and your Verizon wireless router? Do you have more than one device connecting to the Internet?
