16 September 2015. Twitter has teamed up with the Indonesian mobile carrier Indosat. Indosat customers will now be able to pay for text, call and internet packages using the social network. Users just need to send a direct message saying “#TwitBuy” to Indosat’s Twitter account. They will then receive a reply containing instructions on what to do next. It is currently unclear whether Twitter will take a cut of the profits Indosat makes from the initiative. Indosat is the main mobile carrier in Indonesia, with around 68 million users.
