For a significant portion of my holididay driving, my 4S (att) had internet connection where the Mini LTE (att) did not. These were probably 3G rather than 3G+. Does the mini have less downward compatability - how does the iphone 5 compare. I drive the backroads (aka South Texas)...
Mac mini, iOS 6
iPhone 4S only has 3G cellular capability. When 4G symbol is displayed on iPhone 4S screen it only has a fast 3G connection, which is misleading. The iPhone 5, when recieving LTE signal will display on screen LTE.
If you are having a connection issue with your iPhone 5, tap Settings App > General > Reset > Reset Network Settings. When done, in Settings App make sure Cellular Data is ON.
