Problems of Unicom buckle of Japanese version of iPhone5

Hello! The foreign version of the mobile phone is locked and cannot use the signal of the domestic operator. If the card is cracked, let the mobile phone identify that the operator of the number card is a foreign operator supported by the mobile phone through the card camouflage signal. It is suggested that you check whether your mobile phone is equipped with some software for automatically sending international short messages (which can be detected by mobile phone security software) through the background to ensure that your short messages are sent accurately (international access number +86 is required for domestic numbers).
