There are a few reasons why your LTE connection might be slow. One possibility is that you're not getting a strong enough signal from your carrier's towers. This can be due to a number of factors, including your location, terrain, and the number of people using the same tower. Another possibility is that your phone is configured to use a lower-speed LTE band. To fix this, you'll need to contact your carrier and ask them to adjust your phone's settings. Finally, extended LTE connections can be slow because of congestion on the network. This happens when too many people are trying to use the same network at the same time.
