  • What's the difference between off-network and on-network? I'm try to work out which is best for what I want out of the service. I want protection while on my iPhone 5 (both when connected via Wi-Fi and when roaming on 3/4G). Website with product details: http://www.umbrella.com/products/umbrella-security-features/
  • What happens when I turn off 3G and celluar network on iphone? I just went over my internet usage and I have more than 25 days remaining, it has already charged me about $30. If I turn off 3G and celluar network, does that mean I won't have access to the internet, meaning that it won't charge me. How does that work?
  • IPhone ringer toggle is broken, any other way to turn ringer on/off? The speakers very clearly work, and the phone's volume function, just the ringer on/off toggle and ringer volume buttons are non-op. Is there a way to turn my ringer on/off without the toggle and adjust the ringer volume without the buttons. I have an iPhone 4 and am running iOS 7. If there's an app that'll handle it you'll get your 10 pts. For sure.
  • If I turn off the network on an IPhone will i still get texts or calls? Okay so I'm going to the Caribbean in a few weeks and I was wondering about my iPhone. I don't have an international data plan, so I was planning on turning off my network. It says online that you can iMessage people through Wi-Fi. But if i turn it off will i get the messages i missed after I turn it back on? And will i charged for my iMessages?
