Korean communications provider SK Telecom has launched three unlimited LTE plans, Telecompaper.com reported on Wednesday.

Existing subscribers of T&All 75+Unlimited Data Option, T&All 85 and T&All 100, which currently amount to around 1 million, will automatically get the benefits of the new unlimited LTE data plans without additional charges. After exceeding the included data (8, 12, or 16 GB, respectively), users will be provided with 2 GB of data at LTE speeds and then data will be offered at an optimal speed as allowed in the network status. Furthermore, subscribers of T&All 75+Unlimited Data Option will get unlimited calls to mobile numbers while users of T&All 85 and T&All 100 will get unlimited calls to mobile and fixed numbers.

SK Telecom said it will also launch two different optional data plans for LTE and 3G subscribers: Unlimited Data Option for Commuters, which offers unlimited data during rush hours for 9,000 won ($8.51) per month, and the 24-Hour Data Double Option, which is priced at 3,500 won and deducts only half the data from a plan over a 24-hour period.
