Good signal but poor call audio and 3g internet speeds. Any ideas?
I have an iPhone 5, working fine except that even when the signal strength indicators show a good signal, the phone had poor audio quality on cellular calls. Also slow internet speeds. It seems that the signal is being measured as being good but in reality or somewhere down the signal line it's degraded. If anyone has any ideas I'd be really grateful to them.
Is this a good question?
