If you’re new to WhatsApp, there are a few things you should know before starting to use the messaging app. First and foremost, WhatsApp is a secure messaging service that doesn’t store your phone’s contacts or messages in any way. Additionally, WhatsApp doesn’t have any logs of user activity. So if you ever need to contact someone on WhatsApp for the first time, you can do so without fear of being tracked or monitored. To start using WhatsApp, open the app and sign in with your account information (username and password). Then select “WhatsApp” from the top left corner of the main screen. From here, you can select which type of message you’d like to send: text message, voice call, or photo call. If you’re using a phone that supports FaceTime calling, then you can also call someone on WhatsApp by selecting “FaceTime” from the top left corner of the main screen and pressing “call.” Once you’ve selected how you want to send a message, tap “send.” You’ll be asked to enter your recipient’s phone number and other important information such as their name and email address. After sending your message, tap “reply” at the bottom of the screen to add your own comments or answer their question. If they don’t respond within a few minutes or if they don’t answer their phone number when they’re called, try again later that day or even overnight!
