I suggest you do a full wipe in your recovery, reflash the ROM and then wipe cache/ dalvik... see if that helps. If not see if there's a radio you can flash for your device. Finally, see if the ROM was made for your carrier/ region, sometimes that messes it up. Also, try not to post here post in the Q/A of your device or read others comments in the PA thread. There is also a dialer code which involve #*#* that takes you to the testing menu that lets you see the problem but I can't remember it off the top of my head. Hit thanks if I've helped you
for you to solve your problem!
