IN BRIEF | If you're heading off on a trip soon, and you haven't yet sorted out your internet access, consider picking up one of these Pocket Wi-Fi modems, currently on sale at Dick Smith for $39.50.
It takes a 3G mobile network signal, connects to the internet, and provides you with a Wi-Fi hotspot that you can connect up to five devices to, such as your smartphone, tablet and laptop.
The particularly good thing about this modem is that it can connect to 3G at three radio frequencies -- 850MHz, 900MHz and 2100MHz -- which will allow you to connect to just about any mobile network in the world (the main exception being T-Mobile USA, which uses a 1700MHz signal.)
We wouldn't recommend using the Vodafone Australia network with it, as its speed and coverage has been so bad lately that the telco is replacing its entire network.
However, if you unlock the modem from the Vodafone network, you can use it with practically any 3G SIM card worldwide, including Telstra prepaid mobile broadband SIM cards in Australia.
The unlock will cost $75, provided you do it online through vodafone.com.au/unlock.
The combined cost of the modem, therefore is $114.50 -- a bargain!

You can buy the Pocket Wi-Fi 2 modem from Dick Smith's website.
