Yesterday (25/5/2015) I just bought the Maxis Broadband 20GB for RM150. It comes with a free 3G Modem. But it is very dissapoiting.It is very slow. How do I upgrade my modem to the 4G modem? How much do I have to pay?

Also, let say I want to terminate my subcribtion the next month, is there any penalty? Because I asked the seller and she told me that there is NO penalty and that all I have to do is returned the 3G modem back to them.

And, how do I check how much quota do I have left?

Thanks

Better call Maxis center to confirm
