Hi @zerausxela ,
Have you tried another network compatible SIM card in your phone or tried your SIM card in another network compatible phone to see if it worked OK?
Basically swap the SIM cards between two same network compatible phones and check what works where.
Have you tried starting the phone in [https://www.verizon.com/support/knowledge-base-210943/|safe mode] and check if it works OK or not?
How long ago was the screen replaced? Most reputable repairers offer some sort of guarantee on their workmanship even if only 30 days (user abuse excepted of course) so if it was repaired professionally only a short time ago contact the repairer and ask them about the problem as it seems very coincidental
