Your Galaxy uses information from your SIM card to communicate with nearby towers and facilitate a connection. Which LTE bands you are assigned depends on a number of factors, including available bandwidth and your device's supported signals. But if speeds aren't great on your auto-selected tower, you can improve things by manually choosing a band.
Most modern Samsung phones support around 15 LTE bands. With the help of an app, you can manually switch which of these bands you are using, potentially improving performance dramatically. For example, you can use a higher frequency when in a city for higher speeds, then switch to a low frequency for a slower but stronger connection when you're out on the road.
