i use umobile since last year. at that time, their speed was very good but the coverage was very poor between 1 to 2 bar only. sometime i got no signal bar at all but i still can surf the internet. because of that i always got disconnected eventhough i had complained so many times. at last, i complained to SKMM then only they called me to ask about the problem. i had to wait for about 2months for them to make the coverage full. now, i think i am happy with their service. my download can reach more than 300kbps.
