From what I understand, the price of telecommunication services should never really be very high.
This is simply because these services are in huge demand and supply is very rampant so the cost should be very much efficient while retaining the original value of the service.
This is just simply my own personal belief, but companies tend to act on advice that would undoubtedly make the business earn a more substantial income and, concurrently, grow, earning much more respect in its respective industry as well.
