Root Help Mobile Network Unavailable

[Maura constantino]

I have read alot of threads already and haven't found a solution for whats happening, so ill explain...
It js a tmobile LG Leon that is unlocked. Im usjng a prepay Verizon sim. I can use the internet and fbs mefwork is sbowimg on the lockpage as Verizon and inside it is listing my number. But i am unable to hook up to a network. Also whwn trying to make a call i get unable to make mobile call network unavailable.
I also tried miserably to change the APN. Tbat didnt work and now thw blue add button is gone nd im unable to edit. I have tried to us Any Cut or At Cut but the only option for me for LG was debug and could find Config for lg at all. So i uninstalled it.
Will someone please help me! My other pbone screen shattered and i really need this to work. Alzo the device has. Permanent Unlock.
Thanks for your help

In the U.S., Sprint, Verizon and U.S. Cellular use CDMA.
AT&T and T-Mobile use GSM.
CDMA and GSM are total different signals. GSM unlock only work with other GSM networks, Not CDMA.
