What is Call Barring?

Call barring is a service that allows you to block incoming or outgoing calls from specific numbers or types of calls. For example, you can bar all incoming calls, all outgoing calls, all international calls, or specific numbers that you don’t want to receive or make calls to.

Call barring can be useful if you want to prevent someone from using your phone to make unauthorized calls, or if you want to avoid receiving calls from telemarketers, scammers, or unwanted contacts. It can also help you save money by avoiding roaming charges when you travel abroad.

What is Call Forwarding?

Call forwarding is a service that allows you to redirect incoming calls to another number, which can be a mobile number, a landline number, or a voicemail service. For example, you can forward all incoming calls, calls when you are busy, calls when you don’t answer, or calls when you are unreachable.

Call forwarding can be useful if you want to ensure that you don’t miss any important calls, or if you want to transfer calls to another person or device. It can also help you avoid paying for incoming calls when you are abroad, by forwarding them to a local number or a voicemail service.

What is Call Waiting?

Call waiting is a service that allows you to be notified of incoming calls while you are on another call. For example, you can hear a beep or a tone when someone is calling you, and you can choose to answer, reject, or hold the incoming call.

Call waiting can be useful if you want to keep track of who is calling you, or if you want to switch between multiple calls. It can also help you avoid missing urgent or important calls while you are on the phone.
