When Black Friday 2026 is
Black Friday 2026 is Friday 27 November 2026, and Cyber Monday falls on Monday 30 November 2026. Black Friday SIM-only deals appear in the run-up, so you can compare early. Some offers end early, so do not wait too long. We track these deals every day. Bookmark this page and check the live table before you buy.
How to tell a real Black Friday SIM deal
A real Black Friday SIM deal has the lowest real cost over the contract, not the lowest headline price. Real cost is everything you pay over the contract, divided by the number of months. It includes every monthly price, any stated price rise and any setup fee, minus the cash value of a reward card.
Check the price after the offer ends. A cheap first month can hide a higher price later. Since 17 January 2025, providers must show any rise in pounds and pence when you sign up. Read that figure before you agree.
Bonus data is only worth it if you use it. Check how much data you use, then pick a plan that matches. Paying for spare data wastes money. For the lowest real cost on any plan, see our cheapest SIM-only deals.
Black Friday SIM checklist
Five checks stop a Black Friday SIM deal costing more than its headline price.
- Contract length: A 12 or 24-month plan is cheaper up front but ties you in. A 30-day SIM lets you leave with a month's notice.
- Price after the offer: Check the monthly price once the sale ends. Add every stated price rise.
- Data you use: Bonus data only helps if you use it. Check your usage before picking a bigger allowance.
- Network coverage: Every UK SIM-only brand runs on EE, O2, Vodafone or Three. Brands on your current network share its coverage.
- Keeping your number: Text PAC to 65075, then give the code to your new network. Your number moves in one working day.
