Sema Mobile Services Limited is a mobile network operator based in Kenya, Africa. It's identified internationally by its Mobile Country Code (MCC) 639, which designates Kenya, and its Mobile Network Code (MNC) 08. While not as widely known as some of the larger players in the Kenyan mobile market like Safaricom or Airtel, Sema Mobile aims to provide mobile services to specific segments within the country. Their approach often focuses on offering value-added services and targeting niche markets where they can provide a competitive and unique offering. Understanding the MCC and MNC is crucial for identifying and differentiating mobile networks within a country like Kenya. With an MCC of 639, any network operating in Kenya will start with this code, and the MNC (in Sema Mobile's case, 08) distinguishes it from other operators. This allows mobile devices to connect to the correct network and enables roaming agreements with international carriers. While details about Sema Mobile's specific coverage area or subscriber base can be difficult to obtain, their existence contributes to the vibrant and diverse mobile landscape within Kenya, providing consumers with additional options beyond the major operators.
