Yes. WOW! is concerned about your safety. We want you to feel secure that emergency assistance is only three digits away, similar to your standard telephone. That's why 911 Emergency Dialing is included with every WOW! Phone plan. There are some important differences when calling 911 services with WOW! Phone that you should be aware of. Service outages can prevent 911 emergency dialing. Just as your regular cordless phone will not work today without power, your advanced modem does not operate without power. Please note that the WOW! Phone advanced modem does not include back-up power so if there is a power outage, WOW! Phone will not operate unless you have a battery back-up or other power source. In addition, you will not be able to make 911 calls from your WOW! phone if there is a service outage on the cable line connected to your advanced modem.
