Under Data Usage in settings it's showing me a red line for the limit, and an orange line for the warning. However, I can't see how close I am to the warning line with actual data usa

It is a warning concerning your data usage. Go into settings date to fix it

From your phone:

• Dial #WEB# (#932#) to check used and remaining high-speed data for your current billing cycle.
• Dial 611 at any time to connect to our automated telephone system. When you're prompted, say "data usage" to check your line.
• We've even got an app! Download and use MyAccount to check usage for your line and other lines on your account.

From your tablet or computer: Log in to your My T-Mobile account. After you log in, click USAGE to see the per-line usage under the DATAcolumn. You can even check usage history. It's that simple!

I dont think there is an option to do that in android, each app has its own options in regards to video play back.

There are a couple of things you can do to limit your mobile data usage and monitor it:

1. go to your youtube app then press menu (three dots on the top right) then (settings) then (general) then check the first box that says (limit mobile data usage) This only allows HD videos on Wifi

2. go to (settings) then (mobile data usage) then (set data usage limit) This helps to alert you when you come close to finishing your mobile data plan.

I hope this helps

On my Android Phone , I can turn off Data over Phone Networks under SETTINGS/MOBILE NETWORKS.
ALSO SETTINGS/DATA USAGE/VIEW APP SETTINGS/ -disable Autoupdate for apps or Set Mobile Data Limit

You can do 3 things on Nokia Lumia 520
1) to use Data Sense (an windows app) to control your mobile data usage by limiting it to a certain level like 100MB a month or something.
2) to turn mobile data usage off on your phone, by going to Setting> Mobile Network then choose "off" option for Data Connection.
3) to contact your Mobile Network ISP & request a Data Connection deactivation.

The red stand by indicates the set is in PC stand by the blinking orange timer is indicating the timer has been set or has an issue

If you mean data usage, I recommend Networx( www.softperfect.com/products/networx/) .Its a really nifty application that can track all your data and you can set it to warn you when your going over your limit.

How to Restore iPhone 3G to Factory Settings



Make sure you are on the screen that holds your Settings icon. That is the icon with gears pictured in it. Touch the Settings icon.

In the Settings menu, touch the line that says General. It also has a picture of gears.


Scroll down the General page and you will see a line that says Reset. Select Reset.


This screen will show you several options you can reset including setting, home screen, keyboard dictionary, network settings and location warning. However, to erase all data, you will select the line that says Erase All Content and Settings. When you select it, a box will pop up with a red button saying Erase iPhone. There is also a warning saying it will delete all media and data and will take up to an hour. Touch the red button and your iPhone will format itself back to factory settings.
