I'm also having alot of problems with U Mobile.  I live in Pandan Indah and the service there is really bad.  I can't even update my printer driver and each time I access a video or YouTube link on whatsapp, the keeps loading after a few seconds.  Broadband signal is really low and I'm using the P70 plan.  After complaining to U Mobile it was ok for a few days and then it gets worst.

All the people I know who uses U-Mobile also complain regarding the service and speed of the braodband.
