Two iPohne 5 we're bought last year in eBay and were locked the SiM lock. As these two iPhones were located in US and the Carrier is Sprint previously but I use them either in Hong Kong or Mainland. Is there any solution for me to release the SIM lock so that I can use other service provider such as HGC or China Mobile without regional restriction?
iPhone 5, iOS 6.1.4, Second hand product
