What's the signal quality from the nearest tower to your phone?

I'd recommend installing a cell signal level application on your device like one of the following from the PlayStore: Network Cell Info Lite, and/or Advanced Signal Status

If you have an iPhone, then look for something on iTunes that does something similar like OpenSignal or other (I don't have an iPhone).

I've gleaned the following from the web regarding reported metrics in these apps:

RSRP – The average power received from a single Reference signal, and Its

typical range is around -44dbm (good) to -140dbm(bad).

Better than -88dBm RSRP is a strong signal
Between -89dBm and -96dBm is a very good signal
Between -97dBm and -105dBm is good
Between -106dBm and -112dBm is fair
Worse than -113dBm RSRP is poor

RSRQ – Indicates quality of the received signal, and its

range is typically -19.5dB(bad) to -3dB (good).

Greater or equal to -10dB (excellent)

Between -10 to -15dB (good)

Between -15 to -20 (Fair to Poor*)

Less than -20 (Bad*)

RSSNR – Indicates the Signal to Noise ratio of the signal, the higher the better

                Greater or equal to 20 Excellent

                Between 13 to 20 Good

                Between 0 to 13 (Fair to Poor*)

                Less than or equal to 0 (Bad*)

Is the signal quality good to the phone? Then likely it's a cell tower or network congestion issue.

Next, perform a SpeedTest (download the SpeedTest application from the PlayStore). You might want to do this in the morning, afternoon, evening and late late at night. Provide your signal quality and speedtest results to Verizon.
