I left Vodafone a couple of years ago for a cheaper piggyback network. While the savings have been welcome, I’ve really missed having access to unrestricted EU roaming, Vodafone’s VeryMe Rewards programme, in-app customer support and, yes, free wifi on the London underground. But Vodafone's latest sim-only deal is the first offer in a long time that could actually tempt me back. As part of its summer sale, the network has slashed the price of one of its best sim-only plans, which comes with unlimited data. Better yet, it includes a bunch of perks that my piggyback budget provider can't match, and which I’ve been sorely missing since leaving Vodafone. If you're searching for a new sim-only contract, this is one of Vodafone’s best sim-only contract deals yet. Vodafone Unlimited Plus: Was £44 per month, now £26 per month, Vodafone.co.uk(Vodafone)Vodafone has slashed the price of its Unlimited Plus plan from £44 per month to £26 per month.

It also comes with a three-month Secure Net trial, unlimited picture messages and – something I’ve definitely missed – access to the network's VeryMe Rewards programme.But what’s so good about the deal is the price.
