BlackBerry Z10 Unlock if blocked
Hey,
So I purchased a new Z10 a month ago from craigslist. I immediately added the new sim and began using it with t-mobile. Now it doesn't work at all. I received the error message "phone not allowed MM#6". I called t-mobile to see what was going on and they checked the IMEI # and told me that the phone was reported lost by the insurance company and is now blocked. I tried getting in contact with the person who sold it to me and I've had no luck. Basically now I'm stuck. I wanted to know, if I unlock it, will I be able to use it? Or will it remain "blocked" by the insurance company? I didn't want to dish out more money buying an unlock code if it won't work, so please if any one has any solution to my dilemma please help
