Regardless of hardware, my area has terrible coverage. So weak in fact, I cannot make calls from within most areas of my house. This poor signal strength causes my phone to chew through battery faster as it hunts for signal. Why is the signal so poor and how is this acceptable?
The construction methods used in some buildings are known to interfere with signal quality. Do you have similar issues if you are outside in your yard?
One of the other possibilities, depending on where in Unicity this issue is, is that it could be near the height restrictions for the airport. I know I have personally had similar issues in other airport adjacent areas.
Have you reported the issues using the MTS My Network Feedback App?
