The issue is that the phone is currently in storage (he has no use for it until early next year)
So what I want to do is top it up by nominating a number to put $20 credit on.
Can someone tell me the best way to do this?
NonprayingMantis: Just curious, why would you want to top up a phone that is in storage.
What I mean is, why not just wait until you need it before topping it up (circumstances might change between now and then and you might waste your money)
manhinli: I thought Telecom Prepaid doesn't need a top up to keep alive?
My father kept an unused D-AMPS phone for 2 years in storage - still worked, had the same number and a few dollars left in it (of course until 025 was switched off)
