iphone 6 unlocking
I am in the US and looking to purchase an IPhone 6+. I will get it unlocked (after paying full price for the phone) and then order a Vodaphone Sim card from Spain so that when I am traveling there, ( 6 weeks on the Camino) I can use it locally. What do I need to know before starting this process? All advice is appreciated. Especially cost saving. Thank you in advance.
