The Vodafone Sure Signal is an electronic device that connects to your existing router in order to improve the coverage for your mobile devices. This device only works for Vodafone subscribers and has four lights on it to indicate that it is functioning correctly.
Checkmark Icon Light
The light with the "Checkmark" icon next to it indicates that the Sure Signal is switched on and usable. When the Vodafone Sure Signal is updating its firmware, this light will slowly blink on and off.
Cell Phone Icon Light
The light with the "Cell phone" icon next to it indicates the amount of Vodafone mobile devices that are making use of the Sure Signal. With only one device, the light will slowly flash on and off while several devices will make it flash faster. If the light stays green constantly, it means the maximum number of simultaneous devices has been reached.
"@" Sign Icon Light
The light with the "@" sign icon next to it indicates that the Sure Signal is connected to the Internet. The light will slowly flash while the connection is being established or flash quickly if it has problems connecting.
Power Icon Light
The light with the "Power" icon next to it indicates that the Sure Signal is receiving power and functioning correctly. If this light starts to flash, it means that an error has been detected.
