Interisland communication is often accomplished using citizens' band radio. Telephone services are limited on Chuuk, though a cellular network is established within some islands of the lagoon and in the near future on the outer islands. High speed Internet access via ADSL has been made available on a monthly subscription basis on the Island of Moen from May 2010. Tourism, especially scuba diving among the many wrecks of Truk Lagoon, is the island's main industry with live-aboard dives amongst the most popular ways to see the hundreds of wrecks located in the shallow waters of the lagoon. Copra, dried coconut meat, is the only cash crop and output is relatively insignificant. Most of the inhabitants of outlying islands engage in subsistence activity only.
