Telephones - main lines in use: 0
(note: information for US bases only, 2001)
Telephones - mobile cellular: Argentine bases have GSM networks provided by Argentinean carriers Claro and Movistar; Iridium system in use
general assessment: local systems at some research stations
international: via satellite from some research stations
Australian and New Zealand stations
Five locations (Casey Station (AU), Davis Station (AU), Macquarie Island Station (AU), Mawson Station (AU) and Scott Base (NZ)) all have telephone connections that enable direct dialling to and from the outside world. Argentinian and Chilean bases within their claims, which have families living at them, are also connected by direct dial connections.

Data access to the Amundsen–Scott South Pole Station is provided by access via NASA's TDRS-F1, GOES & Iridium satellite constellation. Marisat F-2 provided data communications until it was retired in 2008. For the 2007-2008 season, the TDRS relay (named South Pole TDRSS Relay or SPTR) was upgraded to support a data return rate of 50 Mbit/s, which comprises over 90% of the South Pole's data capability, which is used primarily for scientific data return.

Argentine bases in general: Marambio Base has wireless internet and 2 mobile phones servers
Argentina Bases: Radio Nacional Arcangel San Gabriel, Esperanza Base, on 15476 kHz with 2 kW and 97.6 MHz. QSL cards verified.
Chile Bases: Radio Soberania, Villa las Estrellas on 90.5 MHz with 100 W.
United States Bases: American Forces Antarctic Network AFAN McMurdo, on 93.9 MHz with 30 W and 104.5 MHz with 50 W.
Several bases used their transceivers also to provide amateur radio worldwide communications on HF or amateur radio satellites with specific club callsigns, also useful on utility and emergency communications.
