A prepaid Next G modem is a good way to get go-anywhere access over the holidays, but the rates you get charged are steep. Over at Whirlpool, an ingenious poster has worked out how to take advantage of a current promotion to get cheap data on a $2 SIM.
Essentially, the approach is this: pick up a $2 Next G SIM from a convenience store, and ring Telstra to activate it as a data connection. Telstra is currently offering 1GB of free data on new prepaid Next G modems, but you can also activate a SIM (by phone) and get the same deal.
No doubt Telstra will clamp down on the arrangement eventually, but numerous Whirlpool posters have made it work (using both Next G and other modems), so it may be worth a try if you're looking for some casual Christmas connectivity. Thanks Dan!
