TOM Online Inc, which sells mobile-phone content such as ringtones, said a decision by China Mobile Ltd to display fee reminders before downloads will hurt its main business in the second quarter.

China Mobile started sending fee reminders for so-called WAP services to subscribers in May, and that move will "have a significant adverse impact" on Tom Online's mobile-phone content business, according to a statement posted to the Hong Kong stock exchange by the Internet company yesterday, Bloomberg News reported.
