Sky Mobile SIM Only Deals November 2026: 24-Month & 30-Day Plans Compared
Sky Mobile has some eye-catching SIM-only prices this November, including an affiliate-exclusive 10GB plan for £6 a month, 50GB from £8.50 a month, and flexible 30-day rolling plans from £7. The cheapest headline price isn't necessarily the cheapest contract, though: some offers increase after 12 months and Sky can also change data-plan prices during a minimum term.

Prices supplied in Sky's November 2026 affiliate communication and checked against Sky's public promotions where possible. The £18 Unlimited price should not be treated as guaranteed for a standalone SIM unless the checkout confirms it.
Sky Mobile 30-day SIM-only plans
Don't want a 24-month agreement? Sky also offers 30-day rolling SIMs. According to the affiliate update, the November promotion listed below is available until 11 November 2026, although Sky may run new promotions afterwards. These are introductory monthly prices for the first 12 months, not lifetime fixed prices.
3GB · £7/mth
Then £11/month after 12 months.
10GB · £10/mth
Then £15/month after 12 months.
50GB · £12.50/mth
Then £20/month after 12 months.
What do these Sky Mobile plans really cost?
Headline prices make comparisons difficult when one plan is discounted for 12 months and another has a 24-month commitment. The examples below show what happens if the advertised monthly prices remain unchanged apart from a specified promotional step-up. They exclude any additional price changes, fees or optional extras.
| Offer | Months 1–12 | Months 13–24 | Illustrative 24-month spend |
|---|---|---|---|
| 10GB affiliate exclusive | £6/mth | £6/mth* | £144* |
| 50GB 24-month plan | £8.50/mth | £17/mth | £306* |
*Illustrations only: Sky may increase the price of data plans during the term; check the contract summary. The £6 exclusive offer is described in the affiliate brief as a 24-month offer, but the basket must confirm its exact future price schedule.
On the 50GB deal, £8.50 for 12 months plus £17 for the next 12 months produces a £306 illustrative total, equal to £12.75 a month averaged over two years. This is more useful for budgeting than assuming £8.50 continues throughout.
24-month vs 30-day Sky SIM: which should you choose?
Choose 24 months if…
You're comfortable with a minimum term and the provider's rules on price changes. The £6 plan gives moderate users a particularly low starting bill.
Main risk: Leaving early can mean termination charges, and advertised promotional pricing may change.
Choose 30 days if…
You prefer flexibility, are unsure about network coverage, or expect to switch plans or provider soon. You can cancel with the applicable notice.
Main trade-off: The monthly price may be higher, and the November promotional rates step up after 12 months if you stay.
What do you get with Sky Mobile?
Unused data with Sky Piggybank
On eligible limited-data plans, unused data rolls into your Sky Piggybank and can be kept for up to 12 months. It can be used later or towards qualifying rewards. Unlimited plans do not accumulate rollover data. This makes a smaller allowance attractive if your usage varies from month to month.
O2 network coverage
Sky Mobile uses the O2 network. Coverage can vary significantly indoors, on train routes and in rural areas, so check the signal where you actually use your phone before agreeing to a 24-month plan.
Change your data allowance
Sky's Mix feature lets customers change their data plan. However, a promotional price may be lost when switching to another plan, so read the terms before adjusting a discounted allowance.
Roaming and keeping your number
Roaming isn't automatically free in every destination. Sky currently advertises Roaming Passport Plus at £2 per day in more than 120 destinations, subject to terms and exceptions. To keep your number when switching from another UK mobile provider, text PAC to 65075 and provide the code during the switch.
SwitchKing's view
Which Sky Mobile deal would we pick?
For lower data use: The affiliate-exclusive 10GB for £6 plan is the standout if the direct basket confirms those terms.
For regular streaming or hotspot use: 50GB offers a bigger allowance, but budget for its rise from £8.50 to £17 after month 12.
For flexibility: A 30-day plan is the safer choice if you may need to change providers. Check current introductory pricing before you buy.

Is Sky Mobile 10GB really £6 a month?
Sky's November 2026 affiliate brief lists a dedicated 10GB SIM-only deal at £6 a month on a 24-month agreement, ending 18 November. The link goes directly to an offer-specific basket. Confirm the price and any scheduled changes before completing an order.
Is Sky Mobile 50GB £8.50 for all 24 months?
No. Sky's public plan listing shows £8.50 a month for the first 12 months, then £17 a month. Other permitted price increases may also apply during the minimum term.
Can I get a Sky Mobile SIM without a two-year contract?
Yes. Sky has 30-day rolling plans. Select the 30 Day toggle on its plans page because the default view shows 24-month packages. These plans renew monthly unless cancelled.
Do Sky Mobile 30-day plans rise after 12 months?
The current introductory offer terms show 3GB increasing from £7 to £11, 10GB from £10 to £15, and 50GB from £12.50 to £20 after 12 months if the customer stays on those plans.
When do November's offers finish?
Sky's affiliate update says the 30-day rates finish on 11 November, the exclusive 10GB £6 rate on 18 November, and the 50GB £8.50 affiliate offer on 2 December 2026. Deals can change sooner, and Sky may replace them with new offers.
Can I keep my existing mobile number?
Usually, yes. Ask your current provider for a PAC by texting PAC to 65075, then give that code to Sky when switching. Check whether your existing provider charges an early termination fee first.
Ready to choose a Sky Mobile SIM?
Check the £6 exclusive basket if 10GB is enough, or compare the full range and switch to the 30-day tab if you prefer a rolling contract.
