Long time since I posted a deal..
This is a SIM only plan for tablets/mifi devices. 50gb of 4G data for £30 a month and unlike others it's not a 24 month contract. No it doesn't come with the mi-fi device but these can be purchased online for less than £50.
24 months contract not monthly on Vodafone website.
^30 day contract confirmed in order email.
Voda's 4G Mifi mobile unit is a one of £35 payment with this 50GB/£30 plan on the website.
