What do Indonesia and Ireland have in common?

They both have carriers that launched Twitter’s Text Messaging service today. We are excited to announce that our friends at 3 Indonesia and O2 Ireland have both made the Twitter SMS service available to their subscribers without any additional fees. Sending and receiving text messages with Twitter is just like sending and receiving them with your friends. It’s a simple way to tell the world what’s happening while out and about by quickly sending a text message to Twitter. Additionally, users can turn on text notifications for individual people they follow as well as, direct messages.

Customers of 3 Indonesia have exciting additional functionality available. 3 is the first carrier in Indonesia to support sending photos to Twitter via MMS by incorporating TwitPic. Give it a try today on your 3 Indonesia phone by sending “START” to 89887.

O2 is the first carrier to launch Twitter SMS in Ireland so, if you are a lucky O2 Ireland customer send “START” to 51210 and either sign up for Twitter or activate your phone with your current Twitter username. Also, be sure to check out all of the cool commands we support.
