Hi, How can change data subscr

Hi,

How can change data subscriptions to pay per traffic, want to try.

Pl assist, thanks

Click on "edit profile" then on the drop down change "subscription" to "pay per traffic". Be aware though I think you can only do this once a month.

Means I have to wait for my month subscription expires before I change to PPT ?

I tried changing now and hit modify button , error pop out saying no information has been changed

When I changed from PPT to sub it warned me there was a limit on how often I can do this. If it gave you no warning then things may have changed since I did it or it only warns you from PPT to sub.

Theres no warning just error , from sub to ppt

No problem. :-) I'd changed your data plan to PPT (Pay Per Traffic) and reset your changeable date too. If you'd like to change it back I think you can do again.
