Subject: Will Apple Care About My Problem?

Dear Sir or Madam,

As I bought my iPhone 5 (16/32/64GB, White/Black) in the USA from Sprint, full price with tax, unlocked, it was expected to be a global phone. But now I come across with some problems in China using local carrier, everything is working properly except sending text message, and iMessage and Facetime also seem not to work. This is very serious for Apple and me! Will I have the chance to fix this?

I tried all the possible solutions from the Internet, and the Official solution offered by Apple (https://support.apple.com/kb/TS4459), but it doesn't seem to work.

Will Apple help me with this issue? Please do.

Information of my iPhone:
SN: XXXXXXXXXX
IMEI: XXXXXXXXXXXXXXX
MEID: XXXXXXXXXXXXX
ICCID: XXXXXXXXXXXXXXXXXX
My Apple ID account: XXX@XXX.COM
