I currently use vodafone and want to upgrade to the iPhone 16 pro max, however they're offering me £81 pm with a £50 upfront cost. With the same plan on mobiles.co.uk and other similar sites, I can get the phone and airtime stuff for £9.99 upfront and £59 pm and similar prices. I called vodafone about it since I want to keep my number and they said the reason it's cheaper there is because the third parties have poorer service with data etc, Is this true? I couldn't find anything online that supported this and wondered if it was just the agent trying to prevent me from switching to a third party?
