Note that this option may have some limitations depending on the country: Turkey blocks the IMEI of unregistered devices after 120 days, so if you plan to travel there multiple times, you may be out of luck (AFAIK only residents can register their device). So it is definitely worth checking the rules before traveling to a country.
