From time to time I use my HTC Wildfire S to provide connectivity for my laptop in NZ.

I'm going to Aussie and don't want to pay for data roaming so I was thinking to buy a local dongle+sim and stick it in the laptop.

Then I thought I could just buy a sim and stick it in the phone and do the hotspot thing (on the basis it would save me having to buy a dongle I wouldn't normally use).

Is this a good idea ?

If yes - who's good to buy a sim from ? Will be in southern queensland if that matters. Volumes won't be enormous (bit of console/surfing/rd'ing - not watching videos)

If it's not a good idea who should I buy a dongle+sim from ?

FWIW the spec for the phone is :

HSDPA/WCDMA (850/2100Mhz)
GSM/GPRS/EDGE (850/900/1800/1900Mhz)

Thanks
