How Does WhatsApp Work?
WhatsApp works by using an internet connection on the user’s smartphone to send messages, media, and make calls instead of using carrier SMS and calling plans. Here is a brief overview of how WhatsApp functions:
Creating an Account
To use WhatsApp, first download and install the app on your smartphone from the App Store or Google Play Store. On opening the app, it will detect your phone number automatically. You can also choose to enter your number manually.
WhatsApp verifies the phone number through an SMS message containing a verification code. Once verified, your account is created.
Contacts and Profiles
Once your account is set up, WhatsApp automatically imports your phone contacts who also use WhatsApp. You can view your contacts’ profiles and see when they were last online.
You can also set up your own profile by adding a profile photo, name and status message that contacts can view. Your profile is visible to all WhatsApp users by default.
Messaging
The core functionality of WhatsApp is free messaging and calling. You can send text messages to individuals or groups of contacts on WhatsApp. Messages are delivered instantly over the internet and you can see when recipients have read your messages.
You can send photos, videos and voice messages through WhatsApp as well. There are options to share contact cards, your location or documents like PDFs across chats. WhatsApp uses end-to-end encryption for all messages to secure your chats.
Groups
WhatsApp has a Groups feature that allows you to create groups or groups chats with up to 256 people. You can name the group, add a photo and customize notifications for the group. Groups are useful for friends, family or teams to communicate efficiently.
Calls
WhatsApp supports free voice and video calls through the app. You can make one-to-one calls or group voice and video calls with up to 8 participants. Calls made through WhatsApp are high-quality and use end-to-end encryption like chats.
Other Features
Some other useful WhatsApp features include:
- Status updates – Share text, photo or video status updates that last 24 hours.
- WhatsApp Web/Desktop – Use WhatsApp on your computer by linking to your smartphone.
- Broadcast lists – Send messages to multiple users at once.

Disadvantages of WhatsApp

No SMS Integration
Unlike Apple’s iMessage, WhatsApp does not integrate with your carrier’s SMS/MMS service. It is a standalone app and cannot message people who don’t have WhatsApp installed.
Battery and Data Usage
Constant use of WhatsApp audio calls and video chats can consume significant battery life and mobile data allowance. Frequent use and background data collection can drain your phone battery faster.
Security Concerns
While WhatsApp uses end-to-end encryption, there have been security and data privacy concerns in the past around its ownership by Facebook. Users have to trust WhatsApp’s security model and practices.
Spam Messages
There is an increasing problem of unsolicited spam messages on WhatsApp from unknown numbers or groups. WhatsApp has limited options to block spam other than reporting unknown senders.
Backups Not Encrypted
WhatsApp does not encrypt media and chat backups stored on Google Drive or iCloud. Anyone gaining access to your cloud backups can read your WhatsApp media and messages in plaintext.
Limited Feature Control
Compared to apps like Telegram, WhatsApp has relatively limited options to customize chats, notifications or privacy beyond the basics. Users cannot finely control certain features.
