My Vodafone was due for an upgrade.
After looking at the deal from 3 essentials - Unlimited min/text and 4GB data @ £9/m inc. quidco.
I asked Vodafone if they can match the offer and here is what they offered.
12m - UNLIMITED MINS / UNLIMITED TEXTS / 4GB DATA. This plan also gives you unlimited mins/texts and 500mb data to use for free when roaming in Europe. This is usually £18 a month but because of how long you have spent with Vodafone and the loyalty you've built up over the years we can discount this down to just £10.80 inc vat. On top of this we can also offer you the first 2 months line rental for FREE! ( making the effective monthly cost just £9 to match the offer)
