Mobile ICT operations

Mobitel (Pvt) Ltd. (“Mobitel”), a fully-owned subsidiary of SLT, offers mobile ICT services including mobile telephony services, high-speed broadband, enterprise solutions, international services, and a range of value-added services. Mobitel has been the pioneer in South Asia:

  • To launch a Super 3.5G HSPA network
  • To successfully demonstrate HSPA+ MIMO (Multiple Input Multiple Output) technology
  • To successfully trial 4.5G LTE-Advanced Pro technology
  • To launch the first commercial 4.5G/
    4G+ mobile network
  • To successfully trial the first 5G network, achieving a new speed record of 1.55 Gbps
  • To complete the first 5G voice call
  • To be recognised as the first mobile 5G network on the Ookla 5G map

Mobitel’s coverage extends nationwide and includes international roaming with the partnership of a global web of over 650 networks.

As the only 4.5G/4G+ mobile network in Sri Lanka, Mobitel offers an unparalleled broadband network experience delivering burst speeds up to 300 Mbps and has been recognised by Ookla Speedtest Awards as the fastest mobile network in Sri Lanka.

Mobitel was the first mobile network operator to deploy a Sub-1G mobile broadband network utilising 850 MHz spectrum in Sri Lanka, increasing 4G LTE coverage across the island. In 2018, Mobitel commenced rolling out its largest ever 4G LTE expansion project with over 1,600 LTE sites across the nation together with Voice over LTE (VoLTE), enabling customers to make high quality voice calls over the LTE network.

Taking another innovative step towards the digital transformation, Mobitel provided a state-of-the-art LTE Critical Communications solution to a leading container terminal operator for the first time in Sri Lanka.

With the deployment of the advanced Remote SIM Provisioning platform, Mobitel now connects all new smart devices with embedded SIMs, such as Apple iPhones and smartwatches, to facilitate the growth of new generation devices.

Currently, 62% of Mobitel’s sites are connected with superfast fibre, making Mobitel the largest fibre connected mobile network in Sri Lanka, delivering an unparalleled mobile broadband experience to our customers.

With the launch of South Asia’s first NB-IoT network in the 850/900 MHz spectrum, Mobitel is now capable of delivering coverage with increased penetration, enabling use by sensors embedded deep within concrete structures or underground such as those required for smart meters, disaster monitoring sensors, and car park sensors. Moreover, Mobitel has demonstrated the use of NB-IoT as a powerful technology in urban farming and home safety systems.

Mobitel is the pioneer in 5G in Sri Lanka and South Asia, having publicly demonstrated the first 5G Massive MIMO deployment over 3.5 GHz spectrum. In 2019, Mobitel successfully showcased South Asia’s first 5G deployment over a mobile network, hot on the heels of the 5G deployments in the USA and South Korea, connecting a commercial 5G mobile smartphone to its 5G network. Mobitel went on to achieve a new speed record of 1.55 Gbps for South Asia, a landmark for 5G deployment across the globe.
