I bought a Motorola E5 play it is Network unlocked through Metro. I tried to unlock it with a code online and I could never get the code. I went through Metro's customer service and they could not help me without having the previous owners pin number. I'm trying to activate it with my T-Mobile SIM card how do I unlock it to do so?

The puk code is sim card spesific it comes with the sim card when you get it or you can get it by calling your phone service provider of the sim card to get the puk code.

Java status code: #*53696# (Samsung X600)
If you want to unlock your phone put a sim from another company then type *#9998*3323# it will reset your phone. Push exit and then push 7, it will reset again. Put your other sim in and it will say sim lock, type in 00000000 then it should be unlocked. Type in *0141# then the green call batton and it's unlocked to all networks. This code may not work on the older phones and some of the newer phones. If it doesn't work you will have to reset your phone without a sim in it by typing *#2767*2878# or *#9998*3855# (not tested)

You can never be successful, if the SIM is locked with a pin & you forgot it.
