Tesco Mobile pay as you go: Essentials bundles, topping up, and using it abroad

What Tesco Mobile pay as you go bundles are there?

Tesco Mobile's pay as you go range is called Essentials: a 30-day bundle of data, minutes and texts bought from your top-up credit. Tesco's example is a bundle activated on 5 January that lasts until midnight on 4 February. These were the bundles on Tesco's pages when we read them on 10 November 2026:

The £30 bundle appears on Tesco's tariffs help page but not on its no-contract SIM page, so check it is still on sale. The triple data offer needs a linked Clubcard, lasts three bundle cycles and can't be added after you've bought the bundle. Bundles renew automatically from your balance unless you turn that off.

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

Is Tesco pay as you go SIM only better than a contract?

It depends on whether you value the exit or the price. The £20 Essentials bundle gets you 50GB, or 150GB for three months with the Clubcard offer, and you can walk away any month. Tesco's Black Friday Clubcard SIM only contracts were cheaper per gigabyte when we read them: 75GB for £12 a month on 24 months. Our Tesco SIM only deals page has the contract prices and how the Clubcard price freeze works.

For a visitor or anyone who doesn't want a credit check, pay as you go is the practical choice.

How do you top up Tesco Mobile?

Tesco gives three routes:

• The Tesco Mobile app, by card or voucher.
• A 16-digit voucher, sold in Tesco stores and online.
• Tesco's automated top-up phone line, by card or voucher code.

The limits are specific. A new SIM needs at least £10 of top-up to activate through the app. Each top-up can be up to £30, your balance can't go above £100, and the app takes up to £150 in any 30 days. Tesco says automatic recurring top-ups aren't available. Linking a Clubcard earns 1 point for every £1 you top up.

One rule to note if the SIM will sit in a drawer between trips: Tesco says that if you don't use your phone for six months or more, you'll be disconnected and may lose your number and remaining credit.

How do you get a Tesco pay as you go SIM?

Tesco's no-contract SIM page has an "Order SIM" button for delivery, and its help pages refer to SIMs bought in store. The page we read did not state a price for the SIM itself. Tesco's eSIM help page says digital download eSIMs are "currently available with Pay Monthly deals only", and its pay as you go pages do not mention eSIM, so we could not confirm that a pay as you go Tesco SIM can be an eSIM. Plan on a physical SIM.

Does Tesco pay as you go work abroad?

Yes, with a catch. Tesco says Home From Home covers pay as you go, but on its data abroad help page it adds that your Essentials bundle is what works across the 48 destinations. Without an active bundle, or outside those destinations, calls, texts and data come out of your credit.

Home From Home covers the EU 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 isn't included.

Outside it, Tesco's roaming page says data costs 1p per MB in the USA, Canada, Australia, New Zealand and South Africa for pay as you go and pay monthly, and up to £5 per MB elsewhere. Tesco's 2025 price list, the most recent we found, lists calls to the UK at 89p a minute from the USA and Australia and £1.49 a minute from most of Asia, Africa and Latin America, and texts at 40p. The full region table is in our Tesco Mobile roaming guide.

On pay as you go, your top-up balance is effectively your cap, since you can't spend credit you haven't loaded.

When is a travel eSIM cheaper than Tesco pay as you go abroad?

Inside Home From Home, keep the Essentials bundle: 25GB for £15 covers most holidays.

Outside it, a travel eSIM usually wins on data. At 1p per MB, 5GB in the United States would cost about £51 of credit, and Tesco's £30 top-up limit means several top-ups to get there. Our verified prices, read on each seller's own site in August 2026, were $12.50 for Airalo's 5GB over 7 days in the USA and $13.99 for Saily's 5GB over 30 days. In Turkey, where Tesco can charge up to £5 per MB, Airalo's 5GB over 7 days was $9 and Nomad's 5GB over 30 days was $9.

You can keep the Tesco SIM in for calls and texts and use an eSIM for data, with Tesco's data roaming switched off. Our data roaming guide explains how, and the pay as you go SIM card guide compares other no-contract options. For other UK networks, see the cheap UK SIM card guide.
