U mobile, P1, maxis, digi mobile broadband all cannot play dota. latency high like shyt. if you want cheap, go for streamyx. if you want superb speed and portability, go for Yes 4G. that's the only choice. bare in mind Yes 4G is super expensive. RM168 for 10GB, 1 night dota uses around 200mb. (3-4 hour) so you do your maths.
