I hope someone can help me. Since the update last month I can't send or receive MMS. I can't see the APN settings on my phone as well. It seems since the last update APN settings is no longer shown in the settings screen.
I have the same problem. It started with my phone after the last update in October. It seems that the same issue was being discussed last year. So far no one knows how to fix. It's a real pain.
