Mobitel was incorporated in 1993 as the third mobile telephone provider in the Sri Lankan market. Originally a collaboration between Sri Lanka Telecom and Telstra, Mobitel has been wholly owned by SLT since November 2002.

In January 2004, the company launched its fully-fledged 2.5G GSM network that is EDGE/GPRS enabled and designed to operate on dual band. In December 2007, the company launched its 3.5G HSPA network - the first Super 3.5G network in South Asia. Further, Mobitel successfully demonstrated HSPA + MIMO technology with down link speed up to 28.8 Mbit/s and carried out successful trial of 4G/LTE technology with downlink speed exceeding 96 Mbit/s, for the first time in the South Asian Region. Investments committed to date in the 2.5G/3.5G/4G networks and service offering amounts to over US$ 500mn.[5]

Following the successful implementation and operation of an AMPS/TDMA network in the country, Mobitel launched its GSM operations in January 2004 with the deployment of a fully fledged GSM network in the 800 MHz and 1800 MHz band, which is EDGE/GPRS enabled. In 2005 and 2006, Mobitel traded the 800 MHz band for slots made available from the 900 MHz spectrum. With this enhancement, Mobitel embarked on a field trial of 3G at the 1st International Buddhist Conference held in 2006, setting the stage for the launch of its 3G services in Sri Lanka.

Investments committed to date for this technology to provide 3G and GSM totals over US$200 million.[6] This included increasing the present number of base stations from 600 to 1,500 by the end of 2008{README, 2012}.

Mobitel currently operates GSM, UMTS and also a LTE Advanced network with downlink speed of up to 300 Mbit/s and uplink speed up to 150 Mbit/s.[7][8]

Mobitel provides international services with GSM roaming coverage of over 200 countries[9] and GPRS roaming coverage of over 120 countries[10] including bilateral partnerships with global carriers.
