Is it the phone device or carrier that's causing poor reception?
My phone's reception during calls is very spotty. It fades in and out sometimes. People complain they didn't hear what I said. Sometimes I hear silence on the other end when people are definitely talking.
Is this an issue with the carrier and its coverage or the actual device?

Try using it in an area of full bars. If the issue still happens then it is likely the phone.

The problem is mainly caused by your (poor) location relative to a cell site.
Of course, your phone has limited transmitter power because of its battery capacity
and the physical size of the semiconductors that do the job.
In other words, you can't increase the phone's transmit power by using a higher-capacity battery;
its electronics simply won't produce any more than they were designed to deliver.
Then there is the matter of received signal strength,
the power of the RF the phone gets from a cell site.
Transmitted power decreases according to an inverse square law,
which means that when the distance is doubled the power is reduced by 75%:
Four watts at a given distance becomes one watt at double the original distance.
A receiver can be made only so sensitive.
Even if there is some RF energy from a transmitter arriving at a given location,
it may not be strong enough to be usable.
So, when you are at a location that requires maximum signal strength to enable reliable performance
but the available energy is insufficient, you will experience the effects of weak signals.
In the case of cell phones and other digital radio transmissions, there is often a "cliff effect" ---
moving a few inches one way or another makes the difference between good function and no function.
However, there are cases in which digital signals act a little more like analog signals,
producing a "fringe" effect with variable results as you have experienced.
This is the same as with over-the-air digital TV reception that "breaks up"
due to marginal signal strength.
Cell signals can also be blocked by objects such as buildings.
The exact effect of this depends on several factors.
The only no-cost thing you can do yourself is move closer to the nearest cell site
and/or move so that you have better exposure to the site.
There are cell phone boosters,
but be Very careful about selecting one.
None that will actually work will seem cheap,
and many of those that aren't cheap may be in some way inappropriate for your situation.

Or... you are using the phone in a poor coverage area. For example, you could be indoors and signal strength is weak. In this case it is nether the phone nor the carrier, but how the phone is being used.
Or... you are using the phone in an area where coverage is not good. Examples include certain rural locations, places where there are obstacles between your cell phone and the cell site antenna (stone or concrete wall, hill or mountain...
We don't know how you use the phone, where you use the phone or which carrier provides your cell-phone's service.
There are actually lots of reasons why the symptoms you report might happen. As much as we all want cell phone coverage to be ubiquitous, the nature of radio frequencies used, placement and power of cell antennas, power of cell phone radio transmission and our environment make that extremely challenging.
It is actually pretty impressive that cell phones work as well as they do... The thousands of people who designed the electronics in the networks and cell phones and countless others who designed and installed the networks have done an incredible job getting us to where we are today with these communications devices...
