I'm in the US and have both Multimedia and Premium packages. I tried to get my iPhone 4 (don't ask but iPhone 6 in a month or two) to receive txt messages and connect to the internet via bluetooth but so far not successful. iPhone is paired and works with regular phone calls and notification is turned on for my C300. Any help is greatly appreciated.
