Frequently Asked Questions

Sussex Mobi-Fi™ is the ability to receive or make telephone calls from any device that can connect to the internet via a local area network, WiFi or 4G/5G wireless, such as a smart phone, tablet, laptop, or personal computer.

Yes, at no additional charge. However, the E911 service in the VoIP world is slightly different than that provided on a hard-wired Telco line; because there is no permanent location on the internet (an IP can be anywhere), the E911 operator will ask for a location, as opposed to being able to see it automatically. Your billing address (location of most businesses), is registered with the E911 call centre, as an assist to locating where the 911 call originated.
