well, u-mobile target customers who always talk less than 1 minutes (few seconds). thats why if take one minute charge, of course its expensive... if its 10-20 seconds as example, then here is the advantage of umobile.

btw, seems like many complaints about umobile erk....after all, from the beginning, they need to do something extraordinary to surpass the big barriers of other oldtimers (digi, mxs, celcom). and with the so many con cases reported, i am afraid it just make their chance worsed...
