Điện thoại tôi không cài nhạc chuông khi mua về từ của hàng iTunes Store

Translation:

My phone did not have a ringtone installed when I bought it from the iTunes Store

I can't download a ringtone from the iTunes Store but I can't set it to the ringtone. I lost the ringtone I bought, but when I get a message, I hope someone can help me with my work.
