Call forwarding service needs to be activated by contacting the service provider, because it is not an inbuilt feature in most handsets. There are two types of call forwarding techniques―conditional call forwarding and unconditional call forwarding. Conditional call forwarding involves forwarding calls only if the activated phone is busy or if nobody answers the call, after a desired number of rings. On the other hand, in unconditional call forwarding, all calls are forwarded to the intended or target phone. Let us take a look at the steps for activating call forwarding on your iPhone and Android devices.
