iphone 6s +
i was bought ip in us nd unfortunately when i already at home my ip cant detected that provider of my country. so each one of u know what the problem is this?
Sounds like your iPhone is locked to a wireless provider in the
US. You will have to contact that wireless provider to see if they
offer unlocking and if you qualify. Only the provider to which
an iPhone is locked can unlock it.
What does it say when you look at Settings>General>About>Carrier?
You may have to scroll to see the entry for Carrier.
