"A high quality and purse-easy telecommunication service is an essential need of the people in Jaffna," Lanka Bell managing director Prasad Samarasinghe said in a statement.
"There are thousands of people who would want to be in touch with the loved ones in other parts of the country or overseas as well as with displaced relatives."
Lanka Bell operates a wireless network using code-division-multiple-access (CDMA) technology.
Samarasinghe said the company offers internet and broadband services.
Lanka Bell said its international direct dialing services offered the lowest tariffs through its 'Dial 15' service.
Many residents of Jaffna have relatives abroad who fled the country during a 30-year civil war in the island.
The conflict ended in May with the military wiping out Tamil Tiger separatists.
Lanka Bell said it had 1.2 million subscribers and is the largest fixed access wireless network in the island.
