I have an A1524 iPhone 6 with CDMA radios, sourced in HK. I'm trying to use it with China Telecom and having trouble. WIth the UIM installed, the phone connects, but it appears it is blocked and after 30 seconds or so it goes to no service. I think there is some block on CDMA radio on the HK version. Is there a way to jailbreak this to activate CDMA? The carrier says there is no block on their end. Any ideas?
