if its sprint then its locked - without the password, you cant change the data in the EPST to allow your phone to connect to cricket. to get the password of a sprint phone, youll need to find and download a tool called getSPC.
once you get the password, look at this post:

that post tells you about EPST settings. after you change the EPST settings, youll need to load a PRL. find one off the internet and download it to your phone. then go into your EPST again and load it from there.
after that, you should be allowed to connect to cricket.. but the rom on your phone might have things locked: when i got my sprint mogul, gps and wifi were not usable. after cooking my own rom with ppckitchen, everything worked beautifully.
good luck
