Hi there all! Not sure if this is a phone issue or network but I think it's the phone. The problem is, when I try to make a call, I select a number and it displays "Dialing", then I wait few seconds and it displays "Call ended" and ends the call. No dialling tone or anything....It does it A LOT. And people cannot get hold of me as well. Therefore I miss a lot of calls. I tried switching my SIM card to another phone and its better. Anything I can do? SO annoying, damn expensive phone and cannot use it properly. I am on Three network, UK. Thanks!
