Dear Apple
I bought my iPhone 5S from apple store online last year, but it's unable to join 3G/4G LTE since I have changed my mobile operator. i tried to call the apple support in China, but i 've been told it's not possible to resolve this problem. it's miserable and I wondering how it happened? i didn't buy the product from mobile operator. i hope apple headquarter can help me to resolve this problem.
Thanks a lot
Best Regards
Angela
