Which is why you locate a small NMS outside your network (on a VM
somewhere) whose only job is to start alerting when it can't reach the NMS
inside your network. That also helps when your interior NMS system gets
gummed up or when a general emergency in your locality damages your
infrastructure at the same time as the SMS provider's infrastructure.

If your monitoring system is structured well to begin with, email has
efficacy comparable to sms. A smartphone app expecting heartbeats via your
in-band infrastructure has effectiveness superior to both.
