Was your phone ever able to see the SIM? Did you check to make sure the SIM card is in the phone? What carrier?

If it is an android bump (4.3 - 4.4, 4.4 - 5.0)
You have to flash the radio also.
Do you have your IMEI number in settings?
If you do have it, that is good news, if it is a generic 00777999xxxx that means it is corrupt and would require some software to write the code back to the handset.

What device?
What android version?
Have you updated the OS lately? OTA or Manually?
Does it have "emergency calls only" or "no service" in the statusbar pulldown?
What does the settings, "device status" or something similar say?
It should have sim carrier, network type, IMEI & serial number?
Is IMEI intact or is it a generic one as mentioned above?
Is Serial Number intact or is it 00000000?

So far I have:
Android version 4.4.2
Custom ROM: ?
Operator unknown
Radio off
Out of service
BUT
The Serial Number is intact, which is good news.
At worst it MIGHT be a corrupt EFS partition, but that is the WORST of it,
It could be a network error on there part.
Dead Sim Card.
Or it could be ROM related...
(To eliminate the network possibility put your sim in another phone, maybe a family members and see if you can make a call, this will solve the network & sim question above.)
I'm just gonna ask you a few more questions to understand it a bit more....
Did you flash a Modem/Radio/Baseband with whatever custom ROM you was running?
Was this a sudden thing or was it as soon as you booted the ROM up?
Have you checked the Custom ROM thread to see if anyone else is having network problems?
Do you have ANY backups? Maybe a restore to an earlier version will fix it?
Any EFS backups? This partition (EFS) holds all the valuable information about the device, and is VERY VERY important.
(Last resort)
By the sound of things, I think it may just be a case of re-flashing the radio, it has happened to me from time to time, the first thing I do when I flash TWRP to my device, is backup the EFS and move it off the device, this should be mandatory to ALL of us, saves us a headache,
And a Wi-Fi only smart phone.
Please answer my additionally questions above or by PM.
(I've blocked out the IMEI for your safety, in future, just say if it is 0xxx or is valid, by checking it against either the phone box it arrived in or on the device itself, please don't note it down)
