Maybe for day-to-day communications, but in an emergency, the cellular network can (and has) quickly become saturated due to a barrage of connections, caused by reacting to an emergency. Additionally, the entire local internet can become degraded or disabled due to the emergency itself. It is important to prepare and train with alternate communication tools. No one tool can work in all circumstances, so having an assortment of options is valuable, as you can never know what will or will not work in an emergency, whatever that may be.
