Swisscom customers can use any SIM card they like in their mobile phones from 1 July 2013. Simply synchronise with iTunes to unlock your iPhone.
Unlock your iPhone in the meantime per SMS. Simply send an SMS with the keyword UNLOCK to the number 444.
Procedure (from 1 July 2013)
The SIM lock can only be removed by synchronising with iTunes.
Please insert your new SIM card (preferably not the one from Swisscom) into your iPhone and synchronise it with iTunes on your computer.
After synchronisation, iTunes will notify you that your iPhone has been successfully unlocked.
If you don't insert the new SIM card (preferably not the one from Swisscom) into your iPhone, the data it requires to function properly will not be transferred.
If you do not receive confirmation from iTunes, you will need to reset your iPhone. Before you do this, back up all the data and information you have stored on the iPhone.
