It may seem tireless and pointless to keep adding contacts to your phone just to chat with them on WhatsApp. And yet for many, this is what ends up happening if you want to reach someone whose number you don't want or need to store – causing contact lists to balloon. Here's a quick fix.

Thanks to WhatsApp's "click to chat" function, you finally don't have to save a new contact for every new chat.

This handy feature essentially lets you message any person or company without saving the contact on your smartphone. The only requirement on both sides is an active WhatsApp account, which is helpful for communicating with international contacts.

Here's how it works: In any smartphone or computer browser, type in the address https://wa.me/ followed by typing in the phone number you're trying to reach.

Make sure to add the international dialing code before the number, but without any prefix zeros, plus sign, brackets, spaces or hyphens. For example, the US phone number +1-484-555-1234 would become: https://wa.me/14845551234.

Then tap the enter key and WhatsApp will ask if you want to chat to that number.

Just tap on the "continue to chat" button and the chat will open automatically.

The magic works on smartphones and tablets, as well as on any computer with the WhatsApp web app.

Now your know an easy fix actually does exist!
