What Tesco Mobile offers
Tesco Mobile sells SIM only plans on 12 and 24-month contracts, from small data allowances up to unlimited. It runs on O2's UK network, so coverage and 5G speeds follow O2's footprint.
Tesco Clubcard holders often get access to 'Clubcard Prices' — lower monthly prices on selected plans. If you have a Clubcard, check whether the plan you want has one.
What to check before you buy
Tesco Mobile plans are contracts, not rolling plans, so check the contract length and what happens to the price at the end of the term. Mid-contract price rises must be shown in pounds and pence — look for them in the plan summary.
Check your real monthly data usage first, and confirm current terms on Tesco Mobile's website, as promotions change frequently.
Why we list so many Tesco Mobile plans
Tesco Mobile publishes its full SIM only range openly, which lets us keep a wide, dated snapshot of its prices. That's why it has more entries in our table than most networks — it reflects how much public data is available, not a preference.
