Hi, I'm currently a Maxis Hotlink user. I'd like to ask if I could switch to the Umobile plan while keeping my number. Another thing is I need clarification on the monthly top-up procedure. Is it sufficient to top-up RM30 per month, and use RM28 of that to subscribe to the unlimited mobile internet plan? Will I get validity for the whole month? The free calls and sms will be for how long? And the RM2 credit balance can be used however way I like?
