Erm to be honest not the best mobile broadband dongle on the market. Notice this whilst walking past carphonewarehouse and stated that in-store only £9.95. No need to purchase voucher but bit pointless as you will need a voucher anyway.
I believe you can unlock these dongles to use on other networks.
Just remember you must top up a new voucher each month whilst with vodafone it is unlimited.
Nearly forgot to say.... average speed on these things are around 512kbps download. Really slow. So only good for browsing to be honest. Only excellent for the travelling person. DO NOT rely on these for home only!! Tooo slow...
Can you believe the days when we would not moan about dial-up?
Anyway, I believe only available in store only. So if this gets - cold, i don't really care.
