Networks want you on their plans, because they know people will get cosy and are far less likely to leave once they're signed up. Three has been at it for the past few weeks, and now EE is offering boosted data to try and get you to sign up.
Currently the network is offering an 18 month plan with 60GB of data for just £20 a month. Normally it costs £22 a month for 20GB of data, so you're getting a really good deal here. After all, who doesn't like more for less?
On top of this you can get 100GB of data on an 18 month contract for £25 a month. Sadly this isn't quite as good a deal, as this would normally cost £27 a month. Similarly, EE is also using Black Friday to peddle unlimited data, but this costs the same £34 a month that it always does.
EE's deals may not be as cheap as the other networks, but considering it has some of the extensive 4G coverage (and the fastest speeds to boot) it might be worth the extra cost.
Of course there are more Black Friday deals being offered by EE, and you can read all about those here.
