So you've taken a look through our best SIM only deals page and you think you may have found the ideal SIM for your smartphone. But before you commit to a year's SIM contract, check out this deal from Vodafone.
(Update: Sorry, this spectacular SIM only deal came to an end when the clock struck 11.59pm on Sunday, July 22. But worry not, there are some other fantastic SIMO prices to be had - so be sure to head over to our dedicated guide to today's best SIM only deals).
Vodafone's 18GB and 20GB SIMO deals were competitive enough on their own at £19 and £24 per month respectively, but for a limited time, until the end of July 22, Vodafone is also giving away a tasty Amazon.co.uk Gift Card when you sign up.
You can scoop a £75 Amazon bonus for the 18GB tariff, and a big £100 for that 20GB SIM only deal.
You'll have to go through the links on this page rather than via the Vodafone website itself, as you have to register your details with Giftcloud in order to claim the offer. The links also have the full terms and conditions of this SIMO promotion and will take you through the easy process of claiming.
