Has anyone else had an issue where you can't use mobile data when on a call, I can go on anything as it just hangs just like it does when you don't get a signal the only way I can get it to work is to put my phone on airplane mode and turn it off again then call the person back then it will let me use the data but not for that long I called EE about the issue thinking it was something Todo with them but after testing my SIM in another phone it worked fine they seem.to.think it must be a big on the beta program I just wanted to see if anyone else has this issue before I report it?
