No network connection - Xperia Z Q&A, Help & Troubleshooting

I get network connection on every single rom I can find but when it's Cyanogenmod or based on Cyanogenmod I get no network connection at all.
Tried clean installs of cm but still no network connection, is this a new way by cm to get rid of it's users?

I assume you have made sure that your APN settings are correct ?

Check your baseband if it is "Unknown".

It's unknown and network has worked before once but stopped after I updated it and clean installs didn't make it work again.

I was in similar situation. (no baseband, IMEI, sim-locked)
I restored backup through CWM, but it did'nt help.
I flashed the CM11 after data and cache wipe... and it helped. Everything came back to normal.
I x4.

CM11 no phone service but data works

I just flashed the CM11 rom from this thread: http://forum.xda-developers.com/showthread.php?t=2518124
I have 3g and LTE service depending on where I am with working data but I cannot make or receive phone calls or test messages. Data works fine. I have tried the latest and the oldest radio, no change. Even if I restore back to my stock ROM I still have no phone service but data will work. I have also tried to flash the CM11 rom a few times. I am on the 11/19 nightly. Im not sure what else to try.
I was looking through some setting and found my MIN number is set to 8471110111...Im guessing I have to get the correct number from sprint and figure out a way to change it to the correct number?

[Q] No mobile data after installing custom ROM

Hi All - I tried flashing 2 custom ROM's (Monnlight and Mokee), both install just fine but i am unable to get mobile data on either of the ROM's. Everything works fine on Wifi. I can even make calls fine. My IMEI number is correct, hence not sure why i cannot get the mobile datat to work.
Tried manually entering the APN details, still no luck.
Hoping somebody has a fix.
Have you tried this:
dial *#*#4636#*#*
select WCDMA-preferred or CDMA auto-prl

Thanks Gary, I tried your code and selected various options nine work. I can still see the Exclamation mark and no mobile data. However on the diagnostic page it says "Connected" and network type "HSPA". I have tried multiple settings rebooting, still no luck.
The funny thing is if i switch back to my phone OS which MIUI v6 evrything works fine. I even checked the baseband number its teh same in the working ROM and the non working ROM.
I am really confused what's happening.
It seemed like a ROM issue I installed a non Cyanogenmod based ROM and it worked just fine

No Data On Cyanogen or RR

After unlocking and rooting my stock system, it still worked fine, but I wanted more features so I went to a custom rom.
Neither CM12.1 or RR had mobile data for Verizon.
When I flashed by TWRP backup of /system, I had data again.
According to 6Binford, my APN settings are correct.
Thanks!
If you upgraded from something other than the most recent -44 build, I think you need to update the radio. You can find that in the official CM thread for the Turbo.
I've tried flashing radio files but still no data.
I've also noticed this notification every now and then, even though I am in an area where data works perfectly fine on stock ROM, and even though before this pops up I still had no data:
Data roaming
----------------------
You've lost data connectivity because you left your home network with data roaming turned off.
