Contract free iPhone 5S Verizon
I'm researching about the contract free iPhone 5S. I purchased the contract free iPhone 5S at the Apple Store in Las Vegas 2 weeks ago. I thought the iPhone is unlocked because I paid about 890$ to get the iPhone 5S 64 GB. However I just found out my iPhone is locked by Verizon from the another Apple Store. I'm moving to Australia in this month. I need to use the iPhone in Australia. Do you think is it possible to use it in Australia? I tried to insert the three different SIM cards from Japan. It seems like works fine however the carrier is using CDMA. I'm wondering if my phone is possible to use GSM carrier. Please let me know if you have any ideas!
Thanks,
iPhone 5s, iOS 7.0.3
