Hi Tech Ninjas!
My partner received an iPhone 6 s from her sister in Hong Kong.
She did have an iPhone 4 but had to get a nano Sim.
We'very tried to put the nano Sim in the 6s and says "no service"
But when I put the nano Sim in my work iPhone, it works fine.
Think her new 6s is carrier blocked? Reading online, apparently your carrier can unblock this for you?
