o2sms is a program to send SMS messages using the websites of Irish mobile operators. Despite its name, it supports all three major Irish operators - o2 Ireland, Vodafone Ireland and Meteor Ireland. The program works by simulating a web browser's interaction with those websites. In essence, the program is really just a stripped-down specialised browser. At the time of writing, o2 web accounts have 250 free web texts per month, Vodafone 300 and Meteor 300. After sending a message, o2sms will tell you how many you have remaining.
