Multi SIM PLUS is a service further developed from Multi SIM. By dialing *100#, users can make outgoing calls and receive incoming calls from supplementary SIM cards without having to change the SIM. Details are as follows:

Making outgoing calls

The destination device being called shall display the same number as the caller, regardless of which SIM card is being used to make the call.
Calls can be made from any device, and all at the same time.
Conference calls can be made from any device independently.
The devices cannot be used to call each other (since they use the same number).

Receiving incoming calls

In case of a phone call, all devices will ring at the same time. Once a device replies the phone call, the rest of the devices will display that it is a missed call.
Each device can be used to pick up a call waiting independently from the rest.

Use of Internet, SMS, MMS and USSD

The use of the internet, SMS, MMS and USSD is exactly the same as with the Multi SIM.
