I own two Samsung phones both are 5g one is fold 3 other is flip 4, both support carrier aggregation but due to some reason my network at my home is always 4g never 4g plus on vi. My brother has OnePlus 8 pro he gets 4g plus all the time on vi. When I go outside to other areas with my Samsung devices I get 4g plus but not at a home. Any solution pr why it could be happening
