How To Use WhatsApp | From First Message To Video Calls

WhatsApp lets you send messages, make calls, share files, join groups, and use linked computers after verifying your phone number.

Once your number is verified, learning how to use WhatsApp comes down to a few main areas: Chats, Calls, Updates, and Settings. Most everyday actions begin in Chats, while Settings holds privacy, account protection, storage, and backup controls.

WhatsApp uses an internet connection for messages and calls. A useful first-day setup is straightforward: register your account, send one message, try the attachment controls, make a call, then review the account settings that matter.

Set Up WhatsApp On Your Phone

WhatsApp setup starts with the official WhatsApp Messenger app and a phone number you can verify. Android and iPhone screens differ slightly, but the registration flow follows the same sequence.

1. Install WhatsApp Messenger from Google Play on Android or the App Store on iPhone, then open it.
2. Tap Agree & Continue, select your country, and enter your phone number with the correct country code.
3. Confirm the number and enter the verification code WhatsApp sends to that number. If WhatsApp offers another approved verification method on your account, follow the option shown on screen.
4. Enter the name you want contacts to see and add a profile photo if you want one.
5. Allow contact access if you want WhatsApp to show people from your address book who already use the service.

When the Chats screen opens under your account, registration is complete. If WhatsApp finds an eligible previous backup during setup, follow the restore prompt before starting new conversations.

How Do You Send Your First WhatsApp Message?

A WhatsApp conversation starts from Chats and New chat. Pick a contact, type in the message field, then tap Send.

1. Open Chats.
2. Tap New chat and choose a contact, or use Search to find the person by name.
3. Tap the message field at the bottom, type your text, and tap Send.
4. For a voice message, use the microphone button beside the message field and record your message.

The sent message appears inside the conversation with its timestamp. Replies arrive in the same thread, so you can return to Chats later and tap the contact name to continue.

Share Photos, Documents, Voice Notes And Location

WhatsApp can send more than text from inside any conversation. The attachment control beside the message field opens the sharing choices available on that device.

On iPhone, tap the + button beside the message field; on many Android layouts, tap the paperclip button. Choose the item you need, such as Photos, Camera, Document, Location, or Contact, select what you want to share, then tap Send.

Voice notes use the microphone control in the chat composer. For photos or videos, select the file, add a caption if needed, and check the preview before tapping Send; the media then appears in the conversation.

Using WhatsApp: What Each Main Area Does

WhatsApp separates daily communication into a small set of screens and controls. The table below shows where common beginner tasks live, which cuts down on hunting through menus.

Can You Use WhatsApp On A Computer?

WhatsApp works in a computer browser through WhatsApp Web, and linked sessions sync your conversations across devices. WhatsApp introduced audio and video calling directly in WhatsApp Web in July 2026, with the feature rolling out gradually.

1. On the computer, open web.whatsapp.com.
2. On iPhone, open Settings > Linked devices > Link a device. On Android, open the three-dot menu > Linked devices > Link a device.
3. Use the phone camera inside WhatsApp to scan the QR code shown on the computer.
4. Wait for your chat list to load in the browser.

Once your chats appear, the computer is linked. Meta’s WhatsApp Web calling announcement says web users can make and receive one-to-one and group audio or video calls, use screen sharing, and open a dedicated Calls tab as the rollout reaches them.

Protect Your Account Before You Rely On It

WhatsApp account protection improves when two-step verification, privacy controls, and linked-device checks are set before a problem occurs. These controls live under Settings rather than inside individual chats.

• Open Settings > Account > Two-step verification > Enable, create a six-digit PIN, and add a recovery email you can access.
• Open Settings > Privacy, tap Start checkup, and review the privacy choices WhatsApp presents.
• Inside Settings > Privacy > Calls, turn on Silence unknown callers. Unfamiliar numbers stop ringing your phone, and you can still review those attempts later in Calls.
• Open Linked devices periodically and log out any computer or browser session you do not recognize.
• Never give another person your registration code or two-step verification PIN, even if the request says it comes from WhatsApp support.

Create And Manage Group Chats

WhatsApp groups let several people share one conversation, media, calls, polls, and events. A new group begins from the same new-chat area used for individual conversations.

1. Open Chats, tap New chat, then choose New group.
2. Select the contacts you want to add, then continue to the group details screen.
3. Enter the group name, add an image if you want one, then tap Create.

The new conversation opens as soon as the group is created. Tap the group name at the top to reach participants, notifications, shared media, and admin controls.

Meta’s August 2026 group update added poll end times, hidden voter names, poll-question editing within 15 minutes, and an @all mention. In groups with more than 32 people, only admins can use @all.

Your First Pass Through WhatsApp

A first WhatsApp run-through should cover account setup, one chat, one call, and the main protection controls. Use this sequence once and the app becomes much easier to read at a glance.

1. Install WhatsApp Messenger and verify your phone number.
2. Add your display name and a profile photo if you want one.
3. Open Chats > New chat and send one text message.
4. Use the attachment control to send one photo or document.
5. Open a contact and use the phone or video camera control to test a call.
6. Create or join the group chats you actually need.
7. Turn on Two-step verification and run Privacy Checkup.
8. Review Chat backup if you want a saved copy of your chat history, then check Linked devices.
9. Link WhatsApp Web if you plan to message or call from a computer.

After those steps, the remaining features are optional. Status, Channels, Communities, advanced group controls, account switching, and newer calling tools can wait until you have a reason to use them.
