So I just get myself a new no, apparently an UOX prepaid no..

but after i check on xpax website, i think xpax have better rates..

Xpax = SMS 1cent (same network), 5cent (others)
Voice 28cent for 10minutes (same network), for 5 minutes (others).

While UOX rates..

UOX = SMS 2cent (same network), 8cent (others)
Voice 28cent for 3minutes (all networks)

Correct me if I'm wrong, but apart from the longer expiry date, what is the benefits of UOX compared to Xpax?
