I'm in South America now. I brought a Verizon iPhone 5S running iOS 9. I'm trying to at lease use it as an iPod to get emails but it doesn't let me pass the phone line activation. I have tried two different SIM cards from different phone carriers but it won't let me move farther to get to setting. It tries to activate and then tells me to try later again. The server is not available, try later again, contact apple. How do I do to at least get to settings to do the IOS10 update? I'm very frustrated. I brought my mac but connecting to iTunes doesn't help either. Can somebody help me please? Thank you.
