I was just in France and Switzerland using my S7 from Verizon. I was amazed at how strong the signals were everywhere, even inside large buildings - hotels, on a river boat, on a 7,000 feet mountain and on the train. I do use WiFi calling due to the bad signal here. But, in my house, I only get one bar, if that, with LTE. Anyone know why there is so much of a difference?
