Its product portfolio includes vehicle telematics, industrial networking hardware, electric vehicle charging equipment, telemedicine devices, and electronics manufacturing services (EMS).

Teltonika was established in 1998 by Arvydas Paukštys in Vilnius, Lithuania. The company's first products included a glucose measuring device, a timing system device, and a current meter.

In 2003, Teltonika presented a versatile programmable controller at the Infobalt Expo.

Teltonika introduced its first GPS tracking device, the TBOXN12GPS, marking the beginning of its telematics business niche. ^[1]

In 2005, the company launched its first fleet management platform, TAVL.

A first surface-mount technology (SMT) production line was opened in Liepkalnis district in Vilnius in 2006.^[1]

In 2007, Teltonika introduced its first cellular router, the RUT100, establishing its industrial networking business niche, and produced its first GSM module, the TM2.^[1]

International expansion began in 2008 with the opening of the first foreign offices in Hong Kong and Pakistan, alongside a new division in Kaunas, Lithuania.^[1] The company adapted an export-oriented business model, selling primarily to system integrators and fleet operators outside Lithuania.^[2]

In 2014, Teltonika began providing electronics manufacturing services to external clients – operations that later became the Teltonika EMS subsidiary. Production capacity was progressively expanded through 2017 and 2018 with new SMT lines and automated assembly equipment.^[1] In 2020, the company announced plans for the Teltonika High-Tech Hill technology park in Vilnius,^[3] and reorganised into a company group, establishing the holding entity Teltonika IoT Group with Arvydas Paukštys as president.^[1]

Separate subsidiaries were created for each business niche: Teltonika Telematics, Teltonika Networks, Teltonika Telemedic, and Teltonika EMS. Teltonika Energy was added in 2021 following the introduction of the company's first electric vehicle charging product TeltoCharge.^[1]

In August 2024, Paukštys transferred the management of the group to Marius Derenčius, who became CEO of Teltonika IoT Group.^[1]
