I have asked and, at least for me, the answer is no. It is not unexpected as of course there is no antenna for standard telephone services in Antarctica.
Telephone communications are possible, but using satellite phones. The price are lower than you can imagine. As for other telecom operators, the price depends of the company, the type of contract but it is possible to find rates lower 1 € per minute for calls and less than 0.5 € per text message. Data transfer is relatively expensive, with about 5 € per MB.
This requires a specific device for the call but, overall, the price is even lower to the ones for transcontinental calls of some operators if you do not have a special rate. Unfortunately, calling us in Antarctica is apparently five times more expensive.
