Twitter addicts don’t need to worry about hopping a flight to Indonesia or Ireland any more. The white-hot microblogging service has expanded its footprint to these two countries, with local mobile carriers making Twitter available by SMS without charging any extra fees. Twitter was worried about overseas expansion for a while, because texting costs outside the United States were likely to prevent user adoption.
If you’re in Indonesia and are a customer of 3 Indonesia, the local carrier, Twitter becomes even more valuable. TwitPic is incorporated via MMS, making it possible to tweet pictures easily.And, the folks over at Twitter say more countries are coming, but there’s already a pretty impressive list on board already.
