Saint Lucia has experienced a high rate of mobile phone adoption, making it one of the highest users of mobile phones in the Caribbean region. The country's mobile network development has a significant history. In 2017, 4G started its rollout on the island, but widespread adoption of Internet services remains a challenge, with only 58% of the island's approximately 178,000 inhabitants having access to the internet.

The government of Saint Lucia has recently reached an agreement with the government of Taiwan to roll out a high-speed fibre optic broadband network to all households, aiming to develop infrastructure for tourism and residents. Despite these efforts, satellite solutions continue to play a crucial role in extending connectivity to areas lacking broadband services. BusinessCom Networks provides satellite Internet services that enable local ISPs to extend their networks to rural areas, offering reliable connectivity for IP services like VoIP and videoconferencing.

Additionally, satellite services help extend mobile broadband services across the island, providing quick Return on Investment and delivering low-cost cellular voice, SMS, and data services. These solutions are fully managed by BusinessCom technical staff and are easy to install, with the network capable of being up and running in just 48 hours.
