Three Web Cube Review - Performance, Cost & Verdict Review


Testing the Web Cube in an isolated Northumberland village where fixed line broadband is so bad BT has locked DSL speeds to 0.5Mbit to “stabilise the connection” we found the results a revelation. We regularly hit download speeds in excess of 5Mbit with upload speeds of around 1Mbit. Of some concern was these figures could vary substantially at different times of the day (lows of 0.6 – 1Mbit), but even with Three not promoting the Web Cube outside of its three target cities it still perfectly illustrates the potential of 3G home broadband to free users from DSL hell.


Contrast this with our second scenario in London where fast broadband is plentiful, but a fixed line connection is not always convenient. Again we were able to hit speeds in excess of 5Mbit, but the vastly higher population density meant this could vary even more wildly. Still it remains a viable option. We didn’t get the opportunity to test the Web Cube in Leeds, Edinburgh or Glasgow, though it seems safe to say it shouldn’t perform worse in these locations.  

What about pricing? Heavy downloaders won’t be swayed, but packages are competitive. £15pm gets you 10GB per month on a rolling monthly contract plus a £59.99 one off charge for the Cube while a 24 month contract offers 15GB per month for £15.99pm with no upfront charge. Three provides a data guide (pictured) to indicate usage examples. As such the Web Cube does exactly what it sets out to do: (dependent on location) it provides a potentially nippy connection for reasonable cost with virtually no setup that is a viable alternative to fixed line broadband in slow areas or where fixed line isn’t convenient. So why no TrustedReviews Recommended Award?


On its own the Web Cube is an excellent product, but it is actually undermined by another Three product: the HSPA MiFi. Like the Cube it takes advantage of Three’s faster 21.1Mbit network, offers an equally large 15GB for heavy downloaders for only slightly more (£18.99pm) on a 24 month contract and we found no real world difference in reception or performance compared to the Web Cube. Admittedly MiFi tariffs are more expensive when opting for smaller data packages (for example, £15pm for 5GB on a monthly contract) but we assume if you wish to use either as a replacement for your home broadband you will want sizeable data.

Of course the real killer with the MiFi is it is mobile and can be put in a pocket and used on the move, lasting up to five hours on a charge. This allows the MiFi to work not only as your home broadband (it comes with a neat charging dock), but also as the 3G for your laptop and/or tablet eliminating the need for multiple data contracts and saving further expenditure. In this scenario – good as it is – it is hard to see why you would opt for the Web Cube.

In many ways the Web Cube is a triumph. It combines excellent design with virtually no setup and gets users online, fast. We had excellent, if fluctuating, broadband speeds and while the caveat remains that this will vary from area to area, it is backed up by reasonable data costs.  Strangely the fly in the ointment is Three itself as its latest HSPA MiFi offers all the same benefits while also working on the move. This makes the MiFi a far more flexible product and (with sizeable data packages) little extra cost. We like the Web Cube a great deal, but there is little reason to choose it in this light.
