WhatsApp offers greater security and privacy than SMS. WhatsApp's end-to-end encryption is one of its most noteworthy features, as many people trust it over traditional SMS. Only a few other apps (Signal being one of them) can offer similar online safety to its users.
Each message sent through WhatsApp Business API is a fraction of the cost of sending a text message. You can easily form groups, share files or even receive files from your customers. WhatsApp is much safer as it has end-to-end encryption, making it more secure.
Security and end-to-end encryption
So, is WhatsApp more secure than texting? Well, WhatsApp uses the latest end-to-end encryption protocols – so in theory, all messages sent via WhatsApp can only be seen by the sender and recipient(s).

WhatApp's Low Cost
At the time it was becoming popular, phone providers in many countries charged per text message, or placed limits on how many you could send. Since all you need to use WhatsApp is an internet connection, it was a more attractive alternative to SMS.
Many people now use WhatsApp. It's an easy way to stay connected with loved ones – through photos, phone calls and video calls, as well as messages.
WhatsApp enables friends and family to communicate even if they live on different continents and countries. Even if you live far from each other, you can celebrate festivals by making video calls, sending photos, and watching videos. Today, WhatsApp has become the new vogue.
But is WhatsApp safe for everyone to use? The app uses end-to-end encryption, preventing third parties from accessing data while it's transferred from the sender to the recipient. Because of this, WhatsApp is generally considered safe for messaging.
How to find your number on WhatsApp. WhatsApp doesn't assign you a unique number, so your WhatsApp phone number is just your mobile phone number. But you can view the number associated with your account by going to Settings and tapping your user picture to open your profile.
Do I have to Use My Real Phone Number on WhatsApp? WhatsApp uses your phone number to send the verification codes while registering your account.
Since most mobile data plans in the US include unlimited SMS texts. Therefore, most individuals do not feel the need to download third-party apps like WhatsApp, Line, etc., to contact each other. Instead, they use SMS. Of course, many millions of Americans continue to use WhatsApp.
WhatsApp encrypts every message sent on its platform which means the only people who can decode it are the sender and the receiver. WhatsApp can't access anything you share and nor could a hacker if they were to intercept a message. Love end-to-end encryption!
India has the most WhatsApp users at 487 million (Statista).
This is partly because of free access and especially more varied formats, for example, group conversations and rich content (videos, GIF, emoticons, stickers, etc.). WhatsApp does not eliminate SMS, it rather created a new conversational use.
However, what if you don't want to share your number? Now, you can chat on WhatsApp without sharing your real number. Once the verification is done, enter your name, username, and password with some information. Email verification will be mailed to your email.
For anyone to send you a message on WhatsApp, they must have your number though they don't have to be part of your saved contacts. It works the same way as anyone sending you an SMS message. They don't have to be on your contact list either.
Can someone hack WhatsApp? Sadly, yes. But luckily, you can take several simple steps to limit the damage (or stop it altogether). Checking for suspicious behavior is a good starting point, and you should also check for malware on your device.
Although your messages are secured with end-to-end encryption, you shouldn't send credit card info on WhatsApp. This is because your WhatsApp account is exposed if your phone is stolen. Furthermore, WhatsApp doesn't prevent the recipient from taking screenshots and sending your credit card info to others.
But it is also one of the most secure. WhatsApp uses end-to-end encryption for both individual chats as well as group messages and ensures nobody apart from those who are participating in the conversation has access to the data. WhatsApp also offers two-step authentication and uses a limited amount of background data.
How does it work? It works just like text messaging, but with one crucial difference – the messages are sent over the internet, rather than over the phone network.
WhatsApp uses your cellular data to make "calls," which are actually voice chats. You can always make free calls with an unlimited cellular data plan, or if you use WhatsApp over Wi-Fi. If you have a limited data plan, you might go over the limit on WhatsApp, especially when sending media or on video calls.
When someone asks for your number on WhatsApp, it is generally understood that they are asking for your mobile phone number. WhatsApp is a messaging application that uses phone numbers as unique identifiers for users. To connect and communicate with someone on WhatsApp, you typically need to exchange phone numbers.
WhatsApp had a penetration rate of approximately 97 percent among messaging and chat app users in India and Italy. Phone messaging users in Australia presented the lowest usage share of WhatsApp, with only 33 percent of mobile phone messaging app users reporting engaging with the Meta-owned app.
