Whilst on holiday my phone stopped beingable to send or recieve text messages. It was working for a few days but then just stopped and the message "delete some data to recieve sim messages". I deleted almost everything but nothing has worked. Im now back in the U.K and its still the same. Also, underneath the battery bar is an icon which I have never seen before, its the number 1 with an arrow underneath it going from left to right and pointing mid way thru.
Is this a virus? Can anyone help please?
