How to call someone on WhatsApp by number - briefly?

To make a call using WhatsApp with just the phone number of the recipient, you need to follow these steps:

Open WhatsApp and go to the "Calls" tab at the bottom of the screen.
Tap on the phone icon in the top right corner and enter the phone number of the person you wish to call.

To initiate a voice or video call using WhatsApp, you need to follow these detailed steps:

Open WhatsApp: First, launch the WhatsApp application on your mobile device. Ensure that you have an active internet connection, either via Wi-Fi or mobile data.
Access Contacts: Navigate to the "Chats" section of the app where all your conversations are listed. If the contact you wish to call is already in your chat list, you can tap on their name to open the conversation.
Add New Contact (if necessary): If the person you want to call is not in your contacts list, you will need to add them first. Tap on the "New Chat" icon (usually represented by a pencil or plus sign) and then select "New Contact". Enter their phone number and any additional information required.
Initiate Call: Once you have opened the chat with the desired contact, look for the call buttons at the top right corner of the screen. There are two icons: one for a voice call (phone icon) and another for a video call (camera icon). Tap on the appropriate icon to start the call.
Call in Progress: While the call is in progress, you will see various options at the bottom of the screen. You can mute the call, switch between voice and video calls, or end the call by tapping on the red phone icon. Additionally, you can use the camera button to take a photo during a video call.
Ending the Call: To terminate the call, simply tap on the red phone icon. This will immediately disconnect the call and return you to the chat screen with that contact.

By following these steps, you can easily initiate and manage voice or video calls on WhatsApp using a contact's phone number.
