Does the iPhone use Wi-Fi for everything or just for data?
When you have your iPhone connected to your wireless network at home does it use that connection for everything like voice calls, Internet, and text messaging or does it maintain a simultaneous link to the cellular network for things like voice calls and text messaging?
Your phone uses cellular network for calls and text messages, since these don't require a Wi-Fi to work. (Excluding iMessage, which needs an Internet connection since its Internet based.)
Still don't get why people think that internet is required for calls/texts. They never have. Still don't. The iPhone uses Wi-Fi whenever possible over a data connection. When the Wi-Fi drops the 3G/4G takes over.
- Why does my iphone use data over night when cellular data is turned off? Every night I turn off cellular data and leave the iPhone on and one day I wake up and check my data manager and see i have already used 25 MB please help!
- When you use the amazon cloud on you iphone does that use data? Okay so for Christmas I got an iphone 4s and I have music on the amazon cloud that I want to listen to on my iphone. I have to be careful with how much data I use (especially since my brother can go a bit overboard) So I was just wondering whether just listening to the music on the amazon cloud uses data or not.
- When you have Wi-Fi and cellular data on at the same time, does it use cellular data? If I keep my cellular data on and also have my iPhone connected to Wi-Fi, will it use any of my cellular data?
- When I set up a new iphone and reset everything, does it erase cellular data too? I got a Sprint 3G on my iPhone and I want to reset it. If I reset everything, does it erase the Cellular data with Sprint 3G too. Please I need to know so I can set up as new iPhone by using iTunes on the computer.
