Poor Cell Service or No Service on LG G4

Poor Cell Service or No Service on LG G4

I have tried and tried to fix this issue but am at a loss for what to do. I have recently noticed a severe drop in Service Quality. My G4 will show 3 or 4 bars of service until I tap the send button on the dailer. At that point the bars go away and calls either dont go through or I get an out of service area message. It was never a problem at all until recently. Im sure its not a phone issue. I did a hard reset on it but didnt help either. 


I have the US991 Model of G4. Just put a new sim card in it and didnt fix it either. Coverage map is excelent where I am located. So any help would be appreciated thank you.
