EE do 30GB for £15 per month on a 30 day rolling contract, so this deal means you are paying £120 for the dongle thingie, which seems steep. And a two year contract is not cool.
Good spot thanks. 50GB EE for £26 is decent.
Got to say I used My first months mobile data at the caravan and burned through 60gb in ten days watching netflix and prime with a bit of other streaming thrown in. Luckily I'd signed up for a 30 day contract and free mifi. Unless you are a virgin media customer I'd wait (They currently do unlimited calls/text/data for £25) Other providers often pop up with discounted deals similar. You can get a sim only data plan for 50GB for £26.25 from here https://www.directmobiles.co.uk/EE-30-Day-Mobile-Broadband-SIM-so-5.php
I can't see why anyone would go for a data sim deal like this when you could get a sim only deal with tons of inclusive minutes , text and more data for less money. Plus mifi's are a pain in the ar*e when you could just simply turn your phone into a mobile hotspot and tether numerous devices. My Xiaomi Redmi note 4 will run a portable hotspot for a lot longer time than a mifi does plus I only need to carry one device.
It's about the same price as a SIM only tariff (for a phone) with that amount of data so unless you use a lot of mobile data across multiple devices regularly why would you go for this?
