No, SIM-Lock. But there might be a Region-Lock which needs the phone to be activated with an european SIM card. This is to prevent the import to countries outside of the designated intended area. For questions regarding delievery dates, please contact customer support:

I explained it above. Since it's unclear to me if Turkey belongs to the EU or not, i cannot answer if it will work or not. To be sure you might want to first use a Swiss-SIM to deactivate the region lock and then you can use it anywhere in the world. Ask a friend or someone to borrow a SIM-card if unsure.
