I have an american smart phone that is unlocked and I'd like to use it in Turkey. I've gotten a Vodafone SIM and today I registered it's IMEI (unique ID number) with Vodafone so that it keeps working after the maximum 1 month.
However, today they told me that the registration will expire after 6 months and then I'm screwed, since you can only register once on a passport every 2 years.
Does anyone know if I can register it again on a friend's passport or residency permit after the first expiration? Or maybe I can register it with a different cell company?
