is the baseband unknown? see https://www.hovatek.com/forum/thread-21069.html
is the imei invalid?
did you confirm if these devices use the same network frequency as your local network operator?

I want to assume they're not network locked.
Ensure to set the right APN and change network mode to 2G only then 3G only. See if you get a signal

Was it having no service issue before you flashed pac file or this started after you flashed pac?
By the way, if still no signal when you set network mode to 2G only then that probably means the tab is either network locked, made for a different region or doesn't support the same bands as your sim card
