SMS, which stands for Short Messaging Service, is a communication protocol wherein short text messages can be sent between two mobile phones supporting this feature. SMS has now gradually expanded, and now refers to any device that supports this feature, which includes but is not limited to, landline phones, cordless devices, web servers, etc. Even text messages sent nowadays without using this protocol have come to be referred to as SMS. Usually, mobile telephony providers charge a small per message fee for SMS. There are however, ways to bypass this fee as discussed below.
