On the morning of the transfer, your old service will stop working and your old SIM will deactivate. Later the same day, your Audacious SIM will start to receive and make calls with the number you are transferring over.
You may experience some disruption throughout the day as it will take some time for the changes to take effect, but the transfer should not take too long and everything should be back to normal the following day. If the transfer seems to be taking a long time, simply try turning off and restarting your handset to prompt service connection. If that still doesn't work please contact our Help Team on 0330 135 9700.
