In Italy for the moment and I get constantly 4G+ (KEYone bought in UK) while never happened with my PRIV (purchased in USA) that has always showed "only" 4G
It's all about marketing... what you really have to look at is your actual speed. Lots of provider call their network LTE but true definition it's not real LTE. I believe true LTE has to provide speed of above 100 Mbps
