Last few days my iphone 4s has been playing up and not recieving texts (and then all coming though at once) but still having 3 or 4 bars of signal. Tried restarting the phone but hasnt worked and still struggle to send texts. A few mates have had problems ringing me the last couple of days aswell saying it goes straight to answer machine. Anyone else had these problems or know how to fix it ?
