I have a Samsung Tocco, on T-Mobile contract. I've only had the phone for about six weeks, since renewing my contract.
I've noticed that over the past couple of weeks, whenever I make a call, my phone seems to think I am dialling internationally, as I get a dial tone like I'm calling Spain (or any other country with a similar dialling tone)! I have never taken the phone abroad. At first it was just happening on occasional calls but now it's happening with every call I make.

I have also noticed that sometimes when I dial out, the phone doesn't actually ring- the first thing I hear is the persons voice at the other end when they answer. My fiance says sometimes when he calls me, he gets a v strange loud beep before I answer.

Sorry if I haven't explained this very well, I'm not good with technology. I've taken the phone into the T-Mobile shop but they couldn't shed any light on this, and wanted to send it away to be looked at which I'm obviously not keen on. Anyone got any ideas?!
