Yes it Possible now, Singapore-based software applications developer, U2opia Mobile, has developed a new application for mobile phones that will help you to access Facebook on all kinds of handsets, without paying for a data connection.
“We are using USSD technology, which will enable users to access Facebook without having a GPRS connection on their phones,” said Sumesh Menon, the co-founder and CEO of U2Opia Mobile. USSD is the technology used by GSM cellular telephones to communicate with their users to inform them about their balance at the end of call or for sending miss call alerts.
In india you can enjoy this service from Airtel Network. Airtel users can dial *325# and *fbk# for non-qwerty mobile handsets to access Facebook without subscribing to data plans.
