T Group Call is a group call service provided by SK Telecom.

If you are a SK Telecom customer, use the free call plan and use group calls without any burden!

Recipients (participants) can join the call even without the app.

Even if you don't know when you'll use it, it's reassuring to have it installed ^^*

■ Specialized functions for SK Telecom customers

- Instant call with caller integrated billing: This is a function where the host pays the call costs of all participants and makes a group call. (N times billing) Try using it in combination with free call plans such as band type, plan type, 5GX type, and 0 youth.

- Open open listening: If you have customers who only need to listen during a conference call, open open listening. Open listening participants do not affect the overall call voice and can only listen to group calls.

■ Common features (including third parties)

- Instant call with individual billing for participants: This is an outgoing function created for customers of other companies and SK Telecom Ting/limited/prepaid plan customers. When the room leader calls, the connection number is sent to the participants through ① ARS phone call > ② text message, and each individual can make and participate in the group call. Participants will be charged call fees according to their telecommunication company's policies. (Reflected from app version v2.6)

- Reservation call: This is a function that allows you to make a reservation call at a set time for members who frequently call. Each participant makes and participates in group calls, and call fees are charged according to each carrier's policy.

-Chat room control function (room leader): You can control the chat room by adding participants, expelling, recording, muting, and playing background music.

- Re-entry (Participant): If a chat room is currently in progress, you can re-enter through App > Recent Records.

(The service is currently not provided to Android 9.0 customers due to permission issues on Google’s side.)

- Message: All and 1:1 messages can be sent between app installers.

If you have any problems using the app, please contact T Group Call Customer Center at skt.groupcall@gmail.com.

-For some low-end devices, it may be difficult to use the service, so Android 8.0 or higher is recommended.
