Cell phone signal levels can be affected by a number of different things:
Your location - the further away you are from a cell phone tower the weaker your signal will be, as the signal gets weaker this affects the signal quality which will reduce your data download speeds.
Your local environment - hills, buildings, being in a basement or underground will all affect your cell signal.
Travelling - if you are in a car or train and moving fast you may find your signal will be affected as you move from strong signal areas to weak or no signal areas.
Your phone - some models of phones are just better at getting a signal than others, a phone with low battery can also affect the way your phone works depending on the model.
The Weather - believe it or not even the weather can interfere with your cell signal, heavy rain and snow can degrade the signal temporarily.
