Tesco SIM only deals: Clubcard prices, the network behind them, and what they cost abroad

Which Tesco SIM only deals were listed on 10 November 2026?

Three Tesco Mobile SIM only deals were featured on its offers page when we read it, all with unlimited UK minutes and texts. They are part of Tesco's Black Friday sale, which its Black Friday page says runs from 2 November to 30 November, subject to availability. Tesco also says offers may change during the event, so treat these as a snapshot.

The saving column is Tesco's own figure, and it matches the monthly gap multiplied by the contract length. Tesco's SIM only contracts page says you can pick your data and a 12 or 24-month term, and it mentions an unlimited data SIM, but the plan grid did not load for us, so we could not read prices for every Tesco Mobile SIM only deal beyond the three above.

This is desk research from Tesco Mobile's own pages. We have not bought or tested a Tesco Mobile plan.

How do Clubcard Prices work on a Tesco Mobile SIM only contract?

A Clubcard Price is a cheaper monthly price for customers who link a Tesco Clubcard. The bigger point is what happens in April. Tesco says it will freeze a Clubcard Price deal's monthly price for the length of the minimum contract, and that an April increase only applies once the minimum term ends. Non-Clubcard deals do rise each April, and Tesco says those future increases are shown in pounds and pence when you buy.

Clubcard-linked SIM deals also earn extra points: 300 a billing month when you spend £50 or more in one Tesco shop (up to 3,600 points) and 250 a billing month for £30 or more of fuel at a Tesco petrol station (up to 3,000 points). If you don't shop at Tesco, those are worth nothing to you, but the frozen price still is.

What network does Tesco Mobile use?

Tesco Mobile runs on O2. Its own site describes its 5G as "powered by O2 network". In practice your coverage at home and abroad follows O2's footprint and O2's roaming partners, so a coverage check on O2's map is a fair guide. Our O2 UK page covers the host network's own plans if you want to compare.

Does a Tesco SIM only deal include roaming?

Yes, in Europe. Tesco calls it Home From Home: your UK minutes, texts and data work at no extra cost in 48 destinations, on both pay monthly and pay as you go. The list includes the EU countries plus Iceland, Norway, Switzerland, Liechtenstein, Monaco, San Marino, Vatican City, Gibraltar, the Channel Islands, the Isle of Man, the Canary Islands, Madeira and the Azores. Turkey is not on it.

Tesco says Home From Home was set to stop in 2026 but that it is letting it roll on, with no plans to bring in EU roaming fees soon and at least 30 days' notice of any change. Its roaming terms, effective from 8 September 2025, say it can withdraw the offer with 30 days' written notice.

Outside Europe the picture splits:

• USA, Canada, Australia, New Zealand and South Africa: Tesco's roaming page says data now costs 1p per MB, on pay monthly and pay as you go.
• Everywhere else outside Home From Home: data "can cost up to £5 per MB".

Our Tesco Mobile roaming guide has the call and text rates for each region and the spending caps.

Can you get a Tesco Mobile SIM only plan as an eSIM?

Tesco's eSIM help page says an eSIM is activated either by scanning a QR code or by digital download, and that digital download is "currently available with Pay Monthly deals only". It lists compatible phones from the iPhone XR, Galaxy S20 and Pixel 3 onwards. The page does not say plainly whether a new SIM only order can be supplied as an eSIM, and the SIM only shop page did not mention eSIM either. We could not confirm it from Tesco's own pages, so check at checkout before you rely on it.

Which Tesco SIM only deal suits a traveller?

If your trips are to Europe, any of the three works, because Home From Home uses your UK allowance. The 75GB deal at £12 is the sweet spot: enough data for a fortnight abroad without watching it, and the price is frozen for 24 months.

If you go to North America or Australia, Tesco is unusually cheap among UK networks at 1p per MB. That is still about £10 for each gigabyte, so 5GB on a week in the United States would add around £51 to your bill. Pay monthly customers on older tariffs without a safety buffer are capped at £40 a month of data charges abroad, after which data is barred.

When does a travel eSIM beat Tesco Mobile abroad?

Inside Home From Home, it doesn't. Outside it, usually.

Take a week in the United States. Our verified prices, read on each seller's own site in August 2026, were $21.50 for Airalo's 10GB over 7 days, $22.99 for Saily's 10GB over 30 days and $25 for Nomad's 10GB over 30 days. At 1p per MB, 10GB on Tesco would be about £102.

Turkey, Japan, Thailand and the Gulf are where it matters most, since Tesco's rate there can reach £5 per MB. Airalo's 10GB over 7 days was $14.50 in Turkey and $17 in Japan when we verified it in August 2026, and Nomad's 10GB over 30 days was $10 in Thailand.

Keep your Tesco line on for calls and texts, switch its data roaming off, and use the eSIM for data. Our data roaming guide shows where the setting is, and the cheapest eSIM table ranks plans by cost per gigabyte. For other UK networks, see the UK SIM card comparison.
