I bought a iPhone 6 Plus on kijiji this summer. I was told it was locked to telus. I went to telus to unlock it they said it wasn't locked to them. I called Apple and they said my phone was unlocked. I was able to use my koodo SIM card in it all summer. Now that I'm in Germany my Germany SIM card doesn't work and I get a message saying my phone is locked. Anyone know what to do?
