BT

BT Group, operating under the mobile network code (MNC) 77 and mobile country code (MCC) 235 in the United Kingdom, Europe, forms a significant part of the UK's telecommunications landscape. While BT itself doesn't directly operate a consumer-facing mobile network like Vodafone, EE, or O2, its subsidiary EE (Everything Everywhere) is a major player. Therefore, BT Group's presence is primarily felt through EE's comprehensive 4G and 5G coverage across the UK. This partnership allows BT to leverage EE's established infrastructure and customer base within the competitive British mobile market. Historically, the evolution of BT's mobile offering in the UK is intertwined with the development of EE. The acquisition of EE by BT Group solidified its position within the converged telecommunications market, providing customers with bundled services, including broadband, mobile, and TV. This strategic move enabled BT to compete more effectively with rival companies and provide better mobile offerings to British Customers. The MNC 77 and MCC 235 are therefore intrinsically linked in the U.K to reliable connectivity, bolstered by an established network with continued investment in advanced mobile technology.
