True.
Explanation:
Messaging systems range from semi-public systems such as standard text messaging on mobile phones, to private systems that are closed to anyone outside of invited members.
A messaging system can be defined as an electronic device which enables users to send text messages to one or more users depending on the configuration and it ranges from semi-public systems to private systems.
In a semi-public messaging system, messages can be sent between users with little or no restriction to who can send or receive these messages. An example is sending short standard text on mobile phones.
On the other hand, a private messaging system is a type of system that denies access to individuals outside of the group, only invited members are able to send and receive messages.
