I just got a Sprint galaxy note 3 and im trying to make it cricket with the new gsm network. I ordered a sim card and I attempted to do the sim unlock but it is not working. I rooted it and verified that it is rooted with an app to check it. I also installed super su like the directions said and also installed region lock away. I still cant get the phone to accept the sim. It says "invalid card". I checked the Stats on it and it show network unknow. It doesn't even show the phone number program onto the sim. When I take it out it switches back to sprint.
