Anonymous users2024-02-15Hello! Hopefully, the following will be helpful to you.
At present, it is known that the US version of the unlocker firmware is prone to various problems, such as network instability, recovery lock state, number drop, etc., if you are currently using it normally, it is not recommended to upgrade the firmware.
The mobile phone of foreign sources may not be able to perfectly support the use of telecom networks (first of all, the network standard does not necessarily support telecom CDMA networks, and foreign operators will lock the mobile phone to use their own SIM cards, unable to use the numbers of other operators, and various problems will arise due to immature technology after unlocking), and the quality and after-sales are not guaranteed.
It is recommended that you log on to the online business hall of Anhui Telecom to purchase the CDMA standard iPhone of the Bank of China.
If you still have questions, please keep asking. Have a great day, thank you!
