Hey there and welcome to the Samsung UK Community Forum

Please go to Settings and Reset Mobile Network Settings. This should resolve your issue.

If running the diagnostic tool found in your Samsung Members App does not highlight anything, then can you insert another Networks sim card to test the phone. 

Ultimately, if a factory reset does not help, then a Samsung Service Centre maybe the next step @motokill35 


Daily Driver > Samsung Galaxy s²⁴ Ultra 512Gb ~ Titanium Black.

The advice I offer is my own and does not represent Samsung’s position.
