How to fix IMEI NULL/NULL and no Signal for Samsung Galaxy S4?

Hello,

I really have a problem i cannot seem to find any solutions for. One day i was using my phone when suddenly the 'No signal Sign' appeared at the top. Since then i haven't been able to send or receive any text messages or place any calls. A couple of days later i checked my IMEI, and found out that it was NULL/NULL, i really dont know how to fix this. Someone told me that maybe Samsung had blocked it? I dont know, i really hope you guys can help me fix this because right now i really cannot do anything. I already tried Factory Reset and it didn't fix it (What's more, i lost my Whatsapp and i cannot get it back because it says that there is no data). I bought the phone in the US but it is an international version or so.
Some information about the phone: - FCC ID: A3LGTI9500
SSN: -I9500GSMH,
The model is GT-I9500
