Are Black Friday SIM only deals actually worth it?
Likely, yes, but it will depend on whether the deal you’re considering is right for you and your situation. You need to weigh up how much you currently use your mobile internet and which network best suits your needs before choosing the cheapest deal you can find.
At Uswitch, we make sure to only show you a ‘Black Friday’ SIM only deal if it offers genuinely better value than previous versions of it, which means that it’ll be the best saving you can make for that tariff in the period leading up to Black Friday itself.

What do Black Friday SIM only deals usually include?
Black Friday SIM only offers mostly take the form of discounts. You’re less likely to see lots of add-ons and extra incentives tacked onto SIM only deals because the biggest benefit that these tariffs offer is the monthly saving you get by keeping your existing handset.
However, some networks, like iD Mobile, offer additional perks, such as three months’ free Apple Music and Apple Arcade. Other than these examples, it’s worth looking out for more generic perks that some networks offer – such as O2, which comes with O2 Priority and discounted broadband speed tiers through Virgin Media.
Cyber Monday SIM only deals
Cyber Monday 2026 takes place on Monday 30th November, after Black Friday.
While there aren’t usually a significant number of Cyber Monday-specific deals launched on the day, most SIM only deals that are live on Black Friday will stay live until Cyber Monday at least, which means you should have the whole four-day period to choose some of these networks’ best offers.
