WhatsApp users have been warned against sending certain types of message that could see them hit with a huge bill or even facing legal action.
WhatsApp is the most used messaging app in the world, with more than two billion people using it regularly. More than 100 billion messages are sent each day on WhatsApp.
But those who use the platform must adhere to certain rules and laws, with some of these relating to the types of messages sent.

For example, Mint.com warns people should not share copyrighted content over WhatsApp as if the original producer found out they could file a complaint meaning the person who shared it could be forced to pay damages.
Similarly, the sharing of adult content on WhatsApp can result in legal consequences, if any member of the group chat were to complain about it.
And as the ECHO has previously reported, your WhatsApp account could be banned if you send too many messages.
WhatsApp warns users must not send "bulk messages". This is where a person or organisation send a large number of the same message to many phones.
It is often used by companies trying to advertise a product, or even scammers. However, it can also be used by people trying to inform a large group of people of something, for example a boss trying to get a message to their staff.
Other rule breaks that could see your WhatsApp account banned include impersonating other people and extracting personal information from people. Your account may also be suspended if people report your messages.
If your account is banned, you'll see the following message when trying to access WhatsApp: "Your phone number is banned from using WhatsApp. Contact support for help." WhatsApp said it bans accounts "if we believe the account activity violates our Terms of Service".
WhatsApp's website says: "Please keep in mind, we might not issue a warning before banning your account. If you think your account was banned by mistake, please email us and we'll look into your case."
