I have a Nokia 6300 mobile phone on 02 network, every time I send a message I get the message tone to tell me that it has been sent, If I send 4 messages I get it 4 times etc. how do I turn it off
O2 send this report, so you need to ring O2 customer services and ask them to turn it off, thats what i did with mine, exactly the same problem as you now it's stopped
