South Korean carrier SK Telecom will introduce three different unlimited LTE data plans that will allow unlimited amount of LTE data, voice calls, text messages and membership services from April 3.

According to the operator, 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 have benefits of the new unlimited LTE data plans without additional charges or a separate sign-up procedure.

After exceeding 8GB (LTE T&All 75+Unlmited Data Option) / 12GB (LTE T&All 85) / 16GB (LTE T&All 100) of data use within a month, users will still have unlimited data. They will be provided with 2GB of data per day at LTE speed and data use exceeding this limit will be offered at an optimal speed as allowed in the network status. Moreover, in addition to the unlimited provision of messaging services including SMS, MMS and Joyn.T, subscribers of T&All 75+Unlimited Data Option will have free unlimited intra-network and inter-network voice calls, while users of T&All 85 and T&All 100 will be given both unlimited intra-network and inter-network voice calls as well as unlimited mobile-to-fixed line voice calls.

In addition, SK Telecom is also launching two different optional data plans that provide unlimited data as fitted to the user’s data usage patterns: Unlimited Data Option for Commuters and 24-Hour Data Double Option. With Unlimited Data Option for Commuters, customers can use data unlimitedly at peak hours between 7-9 A.M. and 6-8 P.M. at a monthly fixed rate of KRW 9,000 and 24-Hour Data Double Option, at KRW 3,500, deducts only 50 percent of the data used within 24 hours upon subscription.
