SMS (Short Message Service) are a form of text message that is commonly used in mobile phones. The messages are normally 160 characters long, although sometimes the 224 character 5-bit mode is used. Not only can you get text messages from friends using SMS but you can also subscribe to SMS services which can send you alerts such as news headlines, weather reports and many others. SMS messages do not need the phone they are sent to to be working in order for them to be sent, instead they will be held until the phone is turned on and then received.
