If I set my iPhone to "Voice & Data" under Cellular Data Options, I do not receive any non-iMessage text messages. If I set it to "Data Only" I receive ALL text messages. Here is my issue. Whe it's on "Data Only" if I'm on a phone call, I have no internet access at all which is a hinderance for work meetings, maps, etc. I have to flip it back and forth and reboot my phone each time. Does anyone have a real fix for this? I want to be able to use my iPhone like a normal person - full text messages, full iMessage, full internet.
