Latest Black Friday SIM only news
The first SIM only offers are available now
This year, Black Friday falls on 27th November and Cyber Monday on the 30th. But as predicted, plenty of mobile networks have already put their offers live on SIM only.
So far, we know what you can get on giffgaff, iD Mobile, O2, Sky Mobile, SMARTY and Tesco Mobile. All the rest, you’ll have to wait a little bit longer.
In this guide, we track whether mobile networks are publishing genuine offers, rehashing old ones or just badging things with Black Friday labels and calling it good.
Networks with offers live: giffgaff · iD Mobile · O2 · Sky Mobile · SMARTY · Tesco Mobile
Predictions for other networks: 1pMobile · Three · Ecotalk · EE · Lebara · Lycamobile · Mozillion · spusu · Talkmobile · Vodafone · VOXI

giffgaff: two very good offers on contracts
Genuine offers? Yes, new deals for Black Friday
Dates: 4th & 7th December, depending on offer
Black Fridays can be quiet for giffgaff on SIMs. But this year, they’ve launched what is currently the best big data SIM only deal on the O2 network, with this 200GB whopper available until 7th December:
Their other Black Friday offer is good for giffgaff but still beatable elsewhere with providers on the O2 network. It’s available until 4th December only:
Overall, we think it’s probably only really worth waiting for Black Friday on giffgaff if you’re after an unlimited or big data 18-month contract. Anything else and you’re probably safe to just order now.

iD Mobile: half price offers and hidden exclusives
Genuine offers? Yes but some of our existing exclusives are better
Dates: Ongoing until early December
As usual, iD Mobile have started early. Their headline offers give you discounted months on 12-month and 24-month contracts. But only one works out cheaper than our exclusive deals.
If you want unlimited data, this is extremely eye-catching:
But otherwise, you’re genuinely better off with our exclusives. They’re all on 1-month plans and work out cheaper than any of the main website Black Friday deals:

O2: £19.99 unlimited data and excellent exclusives
Genuine offers? Yes, headline offer was over £30
Date: Until 2nd December
O2 started Black Friday very early this year. Their main offer is this unlimited data Plus Plan, which includes worldwide roaming and a 6-month entertainment subscription of your choice:
It’s a genuine deal. It was £33.99 before Black Friday. And we’ve not seen a Plus Plan this cheap all year. So definitely one to latch on to at this time.
Their other SIM offer for Black Friday is 75GB for £18, which we can easily beat with our exclusive O2 offers under the dropdown below.

Sky Mobile: your first 12 months cheaper
Genuine offers? Sort of
Dates: Available until 2nd December. More deals likely in meantime.
Now that Sky offer 24-month contracts, we’re seeing them offer plans that are discounted for the first 12 months. And that’s what they’ve done with their Black Friday SIMs.
This unlimited deal works out at £21.50 a month, when you account for 12 months at £18 but another 12 months at £25:
But we would point out, their previous deal was just £20 a month flat. So actually, this one leaves you needing to compare again immediately at the end, else you’ll be paying £25 for longer.
It’s a similar story with this deal, which is a little so-so, compared to some of the cheaper networks:
We think there could be some movement on Sky’s 1-month plans in the next week or so. So if you’re after a short-term deal, it might be worth holding off still.

SMARTY: our exclusive beats their main Black Friday offer
Genuine offers? Yes, although similar offers appear regularly
Expected dates: Live now, but expect more throughout the month
Should you still wait? Probably
As per our prediction, SMARTY have started Black Friday early with one single main deal (more will come later). The deal is 80GB for £10 but our exclusive below gets you 20GB extra free:
We don’t expect this to be the end of things for SMARTY. They have a habit of improving their exclusive offers over the Black Friday period. And then releasing one more headline-grabbing deal for their main website.
For that reason, we’d say if you like the deal above, go for it. But if you’re after any other data amount and can wait, you might as well.

Tesco Mobile: Clubcard SIM deals throughout November
Genuine offers? Yes but we have some better exclusives
Expected dates: Now until 30th November. Possible last minute deal
Tesco Mobile are always one of the firsts to put their offers live. Their Black Friday deals are good by their standards but pretty beatable elsewhere purely on price.
Our favourite of their deals is this exclusive which was already available before any Black Friday stuff appeared:
You don’t need a Clubcard. You’re only ever committing to a month at a time. And that’s a really competitive price if you want to get on the O2 network.
Quite often, Tesco will hold back one really competitive offer for the last moment in November. This will probably be something like unlimited data or 100GB+. If you’re only after a small amount, you’re probably safe to order.

Our predictions on other networks
1pMobile: we don’t expect any major Black Friday offers
Genuine offers? Yes, if anything launches
Expected dates: No massive activity expected
Should you wait? We don’t think you need to
1pMobile rarely make dramatic changes to their SIM only prices. So we don’t expect you’ll see a large Black Friday sale. They tend to focus on low-cost, flexible plans rather than quick-fire promotions.
If anything does launch, it is more likely to be a modest data boost on one plan in the £10 range. Maybe 60GB+ for £10 instead of 50GB. We don’t think there will be discounts across the board.
You can see any live promotions above. If one of 1pMobile’s current SIM only plans is already right from you, we think it is pretty safe to buy now rather than wait for Black Friday.

Three: early exclusives followed by half-price SIM deals
Genuine offers? Yes for exclusives, mostly rebadging on their main website
Expected dates: Early November to early December
Should you wait? Probably, something better could come
We expect two types of offer on Three. There will be their main website deals, which will be something like 3 or 6 months half price on 12/24-month contracts. This won’t actually be anything new.
But far more interesting will be the exclusive deals they send to comparison websites like us. These below-the-counter plans offer better value than their Black Friday offers on their main website:
Last year, Three didn’t change things too aggressively to compete with the market. We don’t know what they’ll do this year, as we have no insider information.
In previous years, they have tried to grab headlines with the best main network offer on the market, so we could see a return to that approach. If you’re thinking of joining Three now, you might want to wait.

Ecotalk: a major SIM only Black Friday sale looks unlikely
Genuine offers? Yes, if anything launches
Expected dates: No sale expected
Should you wait? Probably no need
Joining Ecotalk on SIM only is mainly about backing their conservation projects, rather than getting bargain basement prices. We think it’s extremely likely you’ll see large Black Friday discounts in 2026.
You might see a small allowance boost or a few months half price. If so, this will be a genuine offer. Ecotalk’s whole schtick is being straightforward and honest. They won’t muck about with fake deals.
If you like what Ecotalk offer now, there is little reason to wait for Black Friday. We’ve picked out their best deals above to get you the most value today.

EE: expect a couple of big data offers over £20
Genuine offers? Possibly, they have history making deals worse
Expected dates: “Throughout November”
Should you wait? Only if you want a large EE SIM plan
EE say their Black Friday offers will launch throughout November. But we do expect their headline offers to focus on phones, tablets and broadband rather than genuinely cheap SIM only contracts.
We may still see one prominent big-data or unlimited SIM only deal. That will most likely be on a longer 24-month contract at a £20+ monthly price.
It’s worth watching EE like a hawk though. In some years, the offer prior to Black Friday was actually better than what they had on sale over the weekend. Maybe they know people will impulse buy at the higher price.
If price matters more than buying directly from EE, compare the smaller providers using EE’s network too. Their ordinary SIM only prices will almost always be cheaper than anything EE offer, even at Black Friday.

Lebara: expect eye-catching bargain introduction prices
Genuine offers? Yes, but the lowest price will be temporary
Expected dates: Mid-November to mid-December
Should you wait? Yes, if your current deal can wait
Lebara normally compete hard around Black Friday, so we expect several SIM only plans with very low introductory prices – like headline grabbing £1 or 99p deals for a few months.
That opening price will be a real saving. But it won’t be what you pay forever. Check the ongoing monthly cost and the total over your first year before deciding how good each offer really is.
You still get the benefit of a short rolling plan, so you can move again if the standard price stops being competitive. Our Lebara review explains the coverage and extras you get alongside the price.

Lyca Mobile: well priced exclusives and half price months
Genuine offers? Probably
Expected dates: November into December
Should you wait? Probably
Lyca Mobile regularly discount their SIM only plans. And we expect a new set of “X months half price” offers during November. You should get a cheaper starting price on selected plans.
The saving can be worthwhile, particularly if you’ll use their international calls benefit. But similar offers do appear at other points in the year. A fair amount of Lyca’s activity will mainly just be Black Friday branding.
That said, Lyca are always in and around the cheapest mobile providers to join – especially if you’re after one on the EE network. So don’t get too downhearted if their Black Friday offers aren’t too dramatic.

Mozillion: big Black Friday offers on their pay up front plans
Genuine offers? Yes, particularly on upfront plans
Expected dates: During November
Should you wait? Yes, if you can pay up front
We have only been tracking Mozillion for about a year or two. They typically bump all their plans up or down by £1 or £2 every month or so, depending on how much they want to compete in the market.
But they have also in the past experimented with plans that were free or half price for a certain number of months. Over Black Friday, we’d expect a combination of those if we had to guess.
Mozillion are also very keen on their plans where you pay for the entire contract up front. So we expect some deep offers on those. But you will need the best part of a hundred quid going spare to pay for them!
Overall, Mozillion are a still a bit of an unknown. We’d be shocked if they were offering worse value over Black Friday, so it’s worth waiting to see what’s what if you can.

spusu: don’t expect anything dramatic, but does that matter?
Genuine offers? Yes, if a new promotion appears
Expected dates: No major sale expected
Should you wait? Probably not
Despite their reputation for incredibly cheap deals, spusu don’t actually tend to do anything dramatic over Black Friday. Perhaps, it’s because they don’t really have anywhere lower to go on price.
Their range of exclusive plans (beating their main website deals) have been stable for around a year now. We’d be surprised to see them change. There will likely be some Black Friday badging on site.
Of course, we don’t have any insider knowledge and could be completely wrong. But we think you’re actually already safe to order with spusu. We can’t see things particularly shifting, based on previous years.

Talkmobile: expect already-low SIM prices to be improved
Genuine offers? Yes, although changes may be small
Expected dates: November to Cyber Monday
Should you wait? Probably
Talkmobile say their Black Friday sale will run during November and finish on Cyber Monday. But we think that’s mainly their main website deals. Realistically, their exclusive plans will compete all month.
You won’t see anything dramatic. But Talkmobile tend to monitor the market and keep tweaking their deals by a few GB or £ so they always come near the top of comparison tables.
If you’re already out of contract, the biggest saving will be moving to Talkmobile at any time. You probably don’t need to wait to save a £1 or something in November.

Vodafone: expect a premium SIM only plan with a huge allowance
Genuine offers? Possibly, but check the claimed saving
Expected dates: Black Friday week to early December
Should you wait? Only if you want a premium Vodafone plan
Vodafone’s main Black Friday SIM only offers arelikely to focus on a very large allowance or unlimited data rather than a sub-£20 plan. Usually, you’ll get better value joining via Carphone Warehouse than direct.
They come with automatic cashback and much better plan costs in the first place. And you get the full network features you’d get from joining Vodafone directly.
Carphone deals will be competitive all month. Vodafone’s main headline Black Friday offers will probably only be available over the actual weekend. Or a little bit either side.

VOXI: current SIM only exclusives may beat on-site sale
Genuine offers? Yes, but not necessarily better than exclusives
Expected dates: Black Friday weekend into early December
Should you wait? Probably
Quite often, VOXI are one of the few networks who treat Black Friday as a weekend only event. Expect one hero offer like 100GB for £10 or similar, to last only until Cyber Monday.
Meanwhile in the background, we expect their range of exclusive comparison website only deals to continue. These are more competitive than their main website and haven’t changed in a long time:
Despite being cheaper than their parent company Vodafone, we’d say VOXI aren’t actually the cheap and cheerful network people presume they are. Only expect medium levels of value for Black Friday.
