This problem is still continuing. I can text to him, and he gets the msgs. His replies in txt msgs to me are still coming from him, via a completely different number. I can phone him; he can phone me on the usual numbers, but txt msgs from him are not reaching me because I have blocked the strange number. He's been to the shop where he got the phone from and explained the situation. They have never heard of this before and can't advise. So there you are. Has anyone heard of this before? Is it possibly a virus on my phone as he says no-one else has had any problems? Any ideas? Thanks
