Why doesn't my iphone custom ringtone ring?

Don't answer if you haven't used the iphone upstairs. Does iphone have licensed products and customer service? I suggest you download ringtones from professional iphone websites or forums. 9 1 The ringtone downloaded by the assistant usually takes more than 40 seconds, and then there is no sound. Suggest less than 40 seconds. You can go to/Ziyuan /lsheng/ to download ringtones. The bell will definitely work. I have been downloading ringtones here, or I can make my own ringtones with iPhone ringtone making software.
