My brother is on EE and always used to be able to phone me, but for the past 2 weeks he's not been able to, didn't even get to my voicemail. And now I can't phone him either (this has only been for the last 3 days). When I ring him it goes to voicemail straight away even though hes there. I thought it was an EE problem but a friend who's on EE phoned me yesterday. It's driving us crazy as I used to speak to him a lot! Please help!
