giffgaff Black Friday & Cyber Monday Deals and Sale

Here's what we found happened last year:

Looking for a new phone? You could score a big discount this November with a giffgaff Black Friday event. We love giffgaff as a place to get great coverage, handsets, and sim deals, and a Black Friday sale makes it even sweeter. Let’s check out the deals from last year to see what they had to offer.

In November 2025, the giffgaff Black Friday deals included £300 off Samsung Galaxy S25, where you got phone and data from £28.09 a month for 36 months with a £20 upfront payment. There was also £220 off a Motorola Razr 60 Ultra with a monthly payment from £36.28 for 36 months with £25 upfront.

The giffgaff Refurbished section offered big savings, too. We found deals like aniPhone 12 5G like new for £80 off the original amounts. Payments started at £7.25/month + £25 upfront for 24 months, or you could pay £199 in one go. The Refurbished Google Pixel 8 Pro like new featured £30 off with monthly payments starting from £15.17 + £25 upfront for 24 months (£389 total), and the Samsung Galaxy A23 5G like new had £20 off and was £99.

We’ve got everything crossed for this year’s giffgaff Black Friday, so if you’re on the lookout for a new phone deal, it’s a great place to start. Sign up for our site to earn cashback on your Black Friday bargains – it’s free to join and free to earn.
