Bulsatcom is a mobile network operator in Bulgaria, a country situated in Southeastern Europe. Operating under Mobile Country Code (MCC) 284 and Mobile Network Code (MNC) 11, Bulsatcom provides mobile services to subscribers across the country. While Bulgaria's mobile market is competitive, with established players like A1 Bulgaria, Telenor Bulgaria (now Yettel Bulgaria) and Vivacom, Bulsatcom aims to carve out its own niche by offering potentially differentiated services, or focusing on specific demographics. Their network infrastructure and service offerings continue to evolve, potentially including 4G LTE and emerging technologies to improve nation-wide coverage and cater to increasing data demands. Serving a population of approximately 7 million, Bulgaria's telecoms sector is relatively well-developed, and Bulsatcom's role within it is significant as it provides an alternative option for consumers seeking mobile connectivity. Although specific market share data fluctuates, Bulsatcom's commitment to providing reliable mobile services ensures its continued presence. Understanding the role of MCC 284 and MNC 11 is crucial for ensuring devices connect properly to the Bulsatcom network, while also highlighting how Bulsatcom collaborates with other carriers (both in Bulgaria and throughout Europe) via internationally standard identifiers to facilitate roaming, and other inter-network services.
