Tesco was the first supermarket to enter the mobile market and it’s certainly holding its own against the other big competition. If you’re looking for simplicity, great choice and overall value for money, you can’t get much better than Tesco Mobile.

Tesco has a great range of phone contracts and SIM-only deals. Both options offer:
Budget-friendly prices, typically starting at under £10 a month
A range of data allowance, including unlimited
Exclusive prices for Clubcard-holders on selected plans
Frozen monthly prices on selected Clubcard tariffs
4G and 5G coverage
No EU roaming fees.
The main differences to be aware of are around contract length:
SIM-only – You can compare one, 12 and 24-month contract through us
Phone contract – Choose between 12, 18, 24, 30, and 36-month contracts on the Tesco Mobile website.
Just so you know...
You can compare SIM-only Tesco Mobile deals with us but unfortunately not contracts at the moment.
Start by setting a monthly budget you're comfortable with.
Remember to look at the monthly cost, any upfront payments and mid-contract price hikes. All these factors can vary by contract type.
Setting a budget early on can help you narrow down your options and avoid overspending. For example, if you don’t want to spend more than £10 a month, you’ll likely be looking at SIM-only deals.
How much data do you typically use each month? If you regularly stream videos, scroll social media or use your phone on the go, you may need a larger data allowance.
But if you’re often connected to WiFi, a smaller allowance could be enough – and it'll probably be cheaper.
If you need a new phone, think about which device you’d like. Many people stick to a particular brand, such as Apple and Samsung.
But if you don't have a preference, you could save money by switching to a less popular brand.
Also, decide whether you’re looking for a particular model. Tesco Mobile has a wide range of handsets, but if you’re after an iPhone or Samsung, you’ll generally only find the latest releases.
That’s great if you’re in the market for the newest handsets, but it’s limiting if you want an older model, such as the iPhone 15.
One of the most effective ways to find the right option for you is to compare. It takes just 1 minute to see our latest mobile deals1.
You can filter results by monthly cost, data allowance and contract length – whatever matters most to you.

Tesco Mobile runs on O2’s network, but each provider sets its own prices. Tesco Mobile deals could work out cheaper for some thanks to Clubcard tariffs, while O2's bundles and Priority rewards might suit others better.
Compare deals from both providers to see which is the better fit for you.

It depends on the plan. Pay-monthly phone contracts involve a credit check, as you're spreading the cost over the contract. Some fixed-term SIM-only plans may involve a credit check too, but not always.
Monthly rolling SIM-only and pay-as-you-go plans don't need a credit check, since there's no borrowing involved.

What our expert says...
“If you have a Tesco Clubcard and are looking for a phone deal, Tesco Mobile might be worth considering. You could bag exclusive Clubcard prices as an existing customer and earn Clubcard points with selected phone plans.
“You can compare flexible Tesco Mobile SIM-only contracts and data allowances through Compare the Market to find a plan at a price that suits you. Just be mindful of potential mid-contract price increases that could affect how much you pay (though Clubcard tariffs are protected from this).”
