The ITU has assigned telephone country code +290 for Tristan da Cunha; however, residents have access to the Foreign and Commonwealth Office Telecommunications Network, provided by Global Crossing. This service uses a London 020 numbering range, meaning that numbers are accessed via the UK telephone numbering plan. Satellite-delivered internet access arrived in Tristan da Cunha in 1998, but its high cost initially made it almost unaffordable for the local population, who primarily used it only to send email. The connection was also extremely unreliable, connecting through a 64 kbit/s satellite phone connection provided by Inmarsat.
