Well why don't you go to your carrier and have them replace your sim card hopefully that can help!

Re: sim error MM#3

Try cleaning the contacts on the SIM Card and phone, a pencil eraser works well but be careful not to leave any small earser parts behind.  If you continue to get this error have your carrier replace the SIM card.

No use replacing the SIM. I changed my SIM but the problem stays.
