OTE, operating in Greece with Mobile Country Code (MCC) 202 and Mobile Network Code (MNC) 03, stands as one of the leading mobile network operators in the country. As part of the Hellenic Telecommunications Organization (also known as Cosmote), OTE provides a comprehensive array of services, including voice, data, and messaging, leveraging both GSM, UMTS and LTE technologies but also 5G in recent years to cater to a diverse user base across mainland Greece and its islands. OTE/Cosmote has consistently invested in infrastructure upgrades and expansion, aiming to provide reliable and high-speed connectivity, competing vigorously with Vodafone Greece and Wind Hellas also present nationally. Within the competitive Greek telecommunications landscape, OTE/Cosmote distinguishes itself through its extensive network coverage and dedication to technological innovation which it has displayed by the implementation of 5G in early 2021, slightly ahead of other Greek mobile networks. Their commitment extends beyond basic connectivity, encompassing value-added services, data plans, and customer support initiatives tailored to meet the evolving needs of Greek consumers. In a country where mobile penetration is high, OTE's role in facilitating communication, business, and entertainment remains pivotal, solidifying its position as a key player in the broader European mobile network ecosystem.
