Hi wondering if i could port back to umobile prepaid after using u28 for just a month. Anyone can give me any tips?

Hi all,

This new U28 postpaid plan is very interesting and tempting.

I'm currently on Umobile prepaid and I would juz like to clarify;
1. if I convert to postpaid, what happens to my credit balance in prepaid?
2. will I still be entitled the free 50mb per day international roaming?
3.How much would I be actually paying monthly? Is the calculation (RM28+RM10 (duty)*1.06GST) correct?

Thanks.
