USB Wireless Modems
Hi, best if you get Telstra one - more expensive than 3, Boost, etc, but Telstra has the best coverage across Australia and in areas where others will not operate. I have just swapped from prepaid one to post paid, as costing more than neccessary due to change in business operations. Normally $40 per month was more that ample for USB modem and the same for prepaid mobile - mostly get incoming calls, very few outgoing.
Hope you enjoy your stay. I'll be doddling back through Flinders Ranges and up Oodnadatta Track if not too wet in about 2 weeks time.
