- Even if content is only partially downloaded (such as when handset is outside reception range or battery is exhausted), any packets downloaded will still incur communication fees.
- Error messages also incur communication fees.
- When using a network connection-type S!Appli, fees will be incurred each time a network connection is made. Charges may become expensive if high-volume mails are frequently sent, received, or downloaded.
- Please be aware that open content (not listed on the Yahoo! Mobile menu) may automatically undertake transmission upon connection, depending on content. This will generate communication fees.
