What is it? WhatsApp allows your child to send a message to anyone they’ve added to their WhatsApp contacts. Both the sender and the receiver need a WhatsApp account in order to use the service. The free app is available for android devices, iPhone’s and iPad’s, BlackBerry handsets, windows phone devices or nokia phones.
Pros: WhatsApp is completely free for use. Instantly send message to anywhere in the world. Easy to use, even a novice mobile user can use it. It do not have any advertisements on the screen. WhatsApp calling made it more reliable.
Cons: Only smart phones are supported, many people still don’t have them. There is risk, you spouse/girlfriend/boyfriend may read the message. It can be annoying sometimes due to constant messages. Your profile picture is visible to every person having your contact number.
How to stay safe: control your privacy settings. Set your profile photo, last seen, and about, to be seen by everyone, contacts only or no one. Request account info. Turn of read receipts. Leave a group.
