All the phones we sell have no restrictions and are functional with all operators. So you can use a sim card from any operator.

However, it is possible that a European regional block is installed as standard.

To be able to unlock it and use the phone anywhere in the world, a manipulation must be done before leaving. You need to insert a Swiss or European sim card and make a call from Switzerland for about 5 minutes. Once the call has been made, you will be able to use the phone in all countries.
