Multi SIM PLUS+

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:

• 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).

• 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.

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

The main SIM is the SIM card used to apply for services while supplementary SIM cards are those activated to allow you to use iMultiSIM or MultiSIM PLUS services. Differences are detailed as follows:
