If you're looking to get a pay-monthly contract from Vodafone in the near future, then this voucher code should be of great interest to you. We had thought it was expired, but it turns out that all Vodafone have done is knock the 15% off 24-month contracts down to 10% when you order from their website. Just put in the code 24MonthsILS at the checkout to claim your discount. Alternatively, if you only want a 12-month contract the discount remains 15%, so hopefully you'll be able to get a good deal no matter what contract duration you're after. Thanks to crocodileniall @ HUKD for the heads-up!
