How to call on cell phone from internet?

You can use apps like Skype, Google Voice, or WhatsApp Web to make calls from your computer to a mobile number via the internet. Most require creating an account.

For VoIP, services like Vonage or RingCentral offer internet-to-cell calling. They are paid but reliable for frequent use.

Some websites allow calling real phone numbers directly. For example, Call2Friends provides free browser-based calls to mobiles in certain countries.
