Messages not coming through since iOS 8
Since I downloaded IOS8 in my iPhone5 and iPad mini, the default carrier is the internet, using my phone provider only if wifi is not avaliable. So messages are appearing on my iPad (which is of no use whatsoever to me but doesnt actually matter) but arrival on my iPhone is haphazard. It looks as if, when then wifi is not available, they simply don't go through. Some do make it but it can't be relied on. when there is wifi, some go just to my ipad and nto my iPhone. Before IOS8, I didn't get message on my iPad and, as far as I am aware, all messages sent to and from my iPhone went as long as I had a phone signal.
I went on my phone settings to see if I could go back to the "old" way which worked but the only my option it gave me was to turn off messages altogether.
Suggestions very welcome. All I want is for all my inward and outward messages to go via phone signal not wifi.
iPad 2, iOS 5.0.1
