Launched two years ago, the "Facebook For Every Phone" app enables people to connect "no matter what kind of mobile device they use," the company said in a statement.
"Today, millions of people in developing markets like India, Indonesia and the Philippines are relying on this technology to connect with Facebook, without having to purchase a (more expensive) smartphone," Facebook said.
The application works on more than 3,000 different types of low-cost phones "from almost every handset manufacturer that exists today."
As of late March, Facebook reported having 751 million customers using accessing their site on mobile devices, up a whopping 54 per cent from one year earlier.
