People can't leave me voice mails because somehow call forwarding got turned on on my phone and I can't turn it back off because I'm getting something called an MMI error. :|

Why are phones. :|

hmm... i'm trying to see if i can find some sort of answer for you and i'm finding a lot of results for MMI errors when trying to turn on call forwarding, but not for turning it off

Yeah I'm googling to try and fix this and finding a bunch of solutions and nothing's working.
