Has anyone else had an issue with some callers getting a busy signal when they call you? Also some people are saying they haven't recieved my texts or I haven't recieved theirs. It's been going on for 2 weeks or so. It's not happening on my husband's phone. The same people that can't get through to me can get through to him. I put my sim in his phone and I have the same issue. Someone please help. This is my business line and I know I've lost business. I've had my slightest week ever and it is always one of my busiest.
