T group call is a group call service provided by SK Telecom.
When you need voice calls between groups, such as business meetings, team assignments, travel plans, and club meetings,
If you are a SK Telecom customer, feel free to use group calls using the free call plan!
The receiver (participant) can join the call without the app.
Even if you don't know when to use it, it's good to have it installed ^^*

■ Specialized functions for SK Telecom customers
- Immediate call with caller integrated billing: This function allows the moderator to pay the call charges of all participants and make a group call.
- Open listening: If there are customers who only need to listen during a conference call, open open listening. Open listening participants do not affect the voice of the entire call and can only listen to group calls.

■ Common functions (including other companies)
-Individual billing instant call for participants: This is a calling function created for customers of other companies and SK Telecom Ting/limited/prepaid rate plan customers. When the moderator calls, the connection access number is delivered to the participants through ①ARS phone call>② text message, and it is a structure in which individuals make outgoing and participate in group calls. Participants will be charged a call fee according to their carrier's policy. (Reflected from app version v2.6)
- Reservation call: This is a feature that allows you to reserve a call at a set time for members who call frequently. Participants make outgoing calls to group calls, and call charges are charged according to each carrier's policy.
- Chat room control function (host): You can control the chat room, such as adding participants, dropping out, recording, muting, and playing background music.
- Re-entry (participant): If the chat room is currently in progress, you can re-enter through App>Recent History.
(For Android 9.0 customers, the service is currently not provided due to Google's permission issue.)
- Memos: You can send all and 1:1 messages between app installers.

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