Why is my 3G signal stronger than 4G?

In fact, 3G is faster than 4G in some places, largely due to congestion on the 4G network . To examine this, we used Tutela Explorer, a platform that allows for the analysis and visualization of billions of records in real-time, to find the areas of the UK where Three’s 3G network is faster than their 4G network.

But weak, inconsistent, or poor-quality signals can happen for a number of reasons. Averse weather, interference from building materials or terrain, distance from your nearest cell tower, or network overload can all contribute to poor signal.17 Mar 2021
