Most sites charge for downloading their content via a pre-paid system where you pay online via credit card for a set number of credits. Some sites offer a system where you can 'earn' credits for uploading new content. You can then use these credits for downloading content. After choosing the content you want to download, you have to fill in data like the operator you are using and your mobile phone number. You can then preview the content and save it in your phone's memory.
Most mobile phones can store one ringtone and logo.
Some models, such as the Nokia 8810, can store multiple ringtones. Once it reaches the mobile phone, you can listen to the downloaded ringtone and save it. Such sites offer listings of key combinations for popular tunes. 2000 SPH AsiaOne Ltd. All rights reserved.
