Alright, so it's not as sexy as a free Spotify Premium account, but it does mean any new or upgrading customer can back out of a pay-monthly or pay-as-you-go plan within the first 30 days, no questions asked. As Vodafone is keen to point out, this is significantly longer than the industry-standard, 14-day window subscribed to by all other major UK operators. So, if you want to test drive a new phone, or are just prone to buyer's remorse, you now know Vodafone will give you a full month to figure everything out.
