Facebook announced partnerships with over 18 operators in 14 countries to provide users with free or discounted data access to Facebook messaging.

Users on Android, iOS and Facebook for Every Phone (which the company notes is now optimized for chat) will be able to take advantage in the coming months.

“Messaging on Facebook lets people connect with friends and contacts on the go, regardless of what device they are using,” Facebook says in its announcement. “Three out of every four people on Facebook send a message on the platform each month, making messaging one of the most popular activities on Facebook. Today, Facebook messaging and chat can be accessed from more than 6,000 mobile phones via Facebook Messenger, Facebook for iOS and Android, Facebook for Every Phone, m.facebook.com and across other devices with Facebook integration.”

The participating operators include: MN in Portugal, Three in Ireland, Airtel and Reliance in India, Vivacom in Bulgaria, Backcell in Azerbaydzhan, Indosat, Smartfren, AXIS and XL Axiata in Indonesia, SMART in Philippines, DiGi in Malaysia, DTAC in Thailand, Viva in Bahrain, STC in Saudi Arabia, Oi in Brazil, Etisalat in Egypt, and Tre in Italy.

Facebook has done a lot in recent months to make Facebook Messaging a preferred method of chat. Last month, they rolled out free VoIP calling to U.S. Facebook Messenger users, and in December, they started letting users sign up with just a phone number.
