I have new cel phone from cricket I need to transfer phone contacts from tmobile to cricket phone I tried blue tooth but it ask me for a code I didn't know a code

Then you are in a world of hurt... you need that code.

Take it back to where you bought it, they should be able to transfere the data if your old phone still works. Ask Cricket about the code thing.
