If I use data only, open new Hello card today 3rd Feb, there will have HKD48 inside and 2G / 7days free data.
7 days later, add value HKD20, then there will have totally HKD78 inside, can I open 2G / 30days data plan as all money will be used if open successfully?
If open successfully, what will happen when 26th - no money can be deducted? |
