Japanese version of AU iphone5. 6. 14 Why can't I send SMS when I upgrade to Ios7 without locking it? Ask the great god to answer?

Upgrade iOS7, the card can unlock the signal normally, and can't send MMS.

Due to the lack of the support of activation software, the caller ID will be normal only after the prefix "+86" is needed, but the number with the prefix "+86" in AU mobile phone cannot send SMS directly.

Therefore, a number needs to be stored in two ways at the same time: the prefix "+86" is used for calling and the prefix "+86" is not used for sending messages.

China mobile card can directly decode the signal.

Unicom 3G card needs to install "GPP? After opening the patch of 3to2 "software, insert the card sticker and the mobile phone card. When the mobile phone displays" No Service ",enter" Settings-General-Restore-Restore Network Settings "? You can solve the signal problem. (Note: Restore network settings)
