Are you Indian or in India now for enjoying holidays, then good news for you, you can use Twitter from your Mobile phone using Airtel. To get started, send an SMS message from your Airtel Mobile Phone, to 53000 with “Signup†(if you are not with Twitter) or “Start†(if you already have an account on Twitter). If you are not using an Airtel connection, no need to worry as the Twitter-Airtel deal is not exclusively and will probably end after a month. -kmamaji-
This service is pretty cool! I love it..But beware, if you're following a lot of people it might spam your sms inbox and flood it in no time.
