The iMessage service is exclusive to Apple devices. It enables users to send text messages and multimedia content over the Internet. Unlike SMS or photo/video messages, a cellular plan is not required to use this service.

An SMS contains only text and is sent over the mobile phone network. These messages are limited to 160 characters.

Photo/video messages (or MMS, multimedia messaging service) contain attachments, such as photos and videos, and have no character limits. Sending and receiving such messages uses up mobile data. You must therefore enable your mobile data to send photo/video messages.
