KeySIM is a perfect connectivity back up for mobile employees, business travelers and fixed broadband connections. By connecting to Vodafone, O2, EE or Three you get coverage in places where normal SIM cards have no signal.
KeySIM can be used in any 2G/3G/4G/5G compatible tablet, router or dongle or as a second SIM in your smartphone. If you don’t have a dual SIM phone simply hotspot to a router when you have no signal on your smartphone and like magic you are connected to the internet even in remote places.
You can even make and receive calls on your normal number when you have no signal by enabling WiFi calling on your smartphone.
