When you subscribe to Twin Number, you will keep the SIM card which is associated with your work number. Your private number can be your old private number, there’s no need to take a new number.

Outgoing calls, SMSs, and other paid services are billed to the number which was active when the operation was made. Both numbers are billed separately, and the bill contains only these services which are used on this number.

With Twin Number, you have to enter a service code before dialing the number in order to select whether to use your work or private number.

Operation Code
Activate work number *201#
Activate private number *202#
Activated number query *200#

Tip: save these codes as speed dial numbers for quick access.

Caller ID

If you make an outgoing call using the Twin Number service, the receiver of the call sees the number that was activated before the call.

If the incoming call number starts with:

  • 00372, the call is made from a private number
  • a regular prefix (+372), the call is made from work number

If you use TwinSIM service with Twin Number and TwinSIM forwarding is active, all calls received both on private and work numbers are forwarded to TwinSIM device (e.g. smart watch).

Twin Number users should not forward calls from work number to private number, and vice versa, because the phone rings regardless on which number the call is received.

Parking service can be used simultaneously only on one number – either private or work number.



You can now call over the 4G network and enjoy even better voice quality.
