Tesco Mobile can be good value for UK customers when a Clubcard Price plan fits their data needs and O2 coverage works where they use their phone. It is not automatically cheap: the real cost depends on the offer, contract length, any scheduled price rises and how it compares with alternatives available when you sign up.
What recent Tesco Mobile deals cost
A recently crawled MoneySavingExpert comparison page listed these examples. They are a volatile snapshot, not guaranteed current tariffs; confirm the offer and checkout total before buying. MoneySavingExpert’s Tesco Mobile comparison also showed that roaming, eSIM and other features vary by deal.

| 6GB, 5G, 12-month term | £9 per month; Clubcard required | Confirm Clubcard eligibility, term and current price. |
| 50GB, 5G, one-month term | £10 per month | Check the current offer and included features. |
| 100GB, 5G, 24-month term | £14 per month; Clubcard Price | Confirm the minimum term, Clubcard requirement and any later increase. |
| 60GB, 24-month term | £15 per month until 31 March 2027; £15.90 from 1 April 2027; £16.80 from 1 April 2028 | This example has scheduled increases; calculate the full-term cost using the offer shown at checkout. |
The examples differ in data, term and deal conditions, so a lower monthly figure alone does not establish better value. Compare plans with similar allowances and flexibility, and check roaming destinations and limits, minutes and texts, and whether eSIM is offered on the specific tariff.

For a fixed monthly price, multiply it by the minimum contract months to estimate the basic usage cost over the term. If the tariff lists future increases, include each new monthly price for the months it applies. Compare that total with alternatives offering similar data and contract flexibility. The minimum term matters: a 24-month offer can lock you in longer than a one-month plan even if its monthly price looks attractive.

Clubcard Prices and annual increases
Tesco Mobile says Clubcard Price deals require a Clubcard number, and that Clubcard is free to obtain. The provider says the basic monthly usage price is frozen for the minimum contract period on these deals; an annual increase may apply after that period ends. Check the terms of the specific offer and your own contract. Tesco Mobile’s pricing guidance and terms and conditions set out the applicable rules.
Non-Clubcard price-rise terms depend on when the customer joined and the deal type. Tesco Mobile says non-Clubcard customers joining from 17 December 2024 have the annual increase stated in pounds and pence at sale for the minimum term. For non-Clubcard deals started from 27 March 2023 through 16 December 2024, Tesco says the increase is linked to January CPI plus 3.9%. Customers who joined before 27 March 2023, or joined from that date on a Clubcard Price deal, face the annual increase only after the minimum contract period ends. Existing customers should check their own agreement because terms differ by cohort.

Ofcom says rules banning inflation-linked price rises in new contracts took effect on 17 January 2025. That does not rewrite older contracts; Tesco’s stated terms distinguish customers by joining date and deal type. Tesco says: “We’ll always let you know at least 30 days before we make any changes to our pricing.”
Will Tesco Mobile work where you need it?
Tesco Mobile uses O2’s network. Tesco claims 99% UK population coverage on 4G and says 5G is growing in many major towns and cities. That is a provider claim, not an independent measurement or a guarantee of reception at a particular address, indoors or along a regular route. Check the Tesco Mobile coverage information for the places you use your phone.

Tesco also says it is trusted by over 5.5 million customers and has more than 500 Phone Shops in Tesco stores nationwide. These are company claims, with no publication year stated on the page reviewed; neither establishes that its plans are cheaper than competitors.

- A Clubcard Price offer provides the data you need at a total cost that compares well with similar current plans.
- You are comfortable with the contract length and any listed price changes.
- O2 coverage is suitable at your home, work and regular travel locations.
- The tariff’s roaming, eSIM and other terms match how you intend to use it.
If one of these conditions fails, a different plan may suit you better even if Tesco’s headline monthly charge is low. Compare the total term cost and service conditions rather than relying on the word “cheap.”
