Well, reason is that when You buy a phone in Bosnia, You can not be sure that phone is not from other network, that is not stolen from the truck etc. and soled to You. (in this case me). It gets to the shop like all other phones, who knows from where. For Bosnia, it's a critical mission . I'm not sure from where is my phone and is it legally imported in country. I can be sure only if I buy phone at local operator. It is not a case, this time. So, will someone help me?
