  8. 8. Asia is also using 3G services very well.Dialog Axiata PLC was First to serve 3G Service in South Asia in 2006A lot of companies like BSNL, WorldCall, PTCL, Maxis, Vodafone,Airtel, Idea Cellular, Aircel, Tata DOCOMO and Reliance havereleased their 3G services.11 December 2008, India entered the 3G arena with the launch of 3Genabled Mobile and Data services by Government owned MahanagarTelephone Nigam Ltd MTNL in Delhi and later in Mumbai.After MTNL, another state operator Bharat Sanchar Nigam Ltd.(BSNL) launched 3G services on 22 Feb 2009 in Chennai and laterlaunched 3G as Nationwide.
