Compare Tesco Mobile SIM Only Deals

Tesco Mobile uses O2's network, so the coverage you get for calls, texts and data follows O2 in your area. Where O2 has rolled out 5G, you can use it on a plan and phone that support it. As always, signal is the deciding factor with any SIM, so check O2 coverage at your home, work and regular routes before you make the switch.

Tesco Mobile stands out for choice. There is a wide range of contract lengths and flexible plans, so you can go short and adaptable or longer for better value. Capped contracts are a useful safety net: you cannot be charged above your plan, which avoids bill shock. The live deals above show the current allowances and contract lengths so you can match a plan to your budget.

Tesco Mobile raises the price of its standard plans each April, while Clubcard-priced plans are sold as frozen for the term. Our guide to SIM only mid-contract price rises shows how that compares across networks.

The signature perk is Clubcard points, which you collect on your plan and can spend like any other Tesco shopper. Capped contracts protect you from going over, and there are family-friendly perks if you have more than one line in the household. Exactly what each plan includes varies by deal, so read the terms in the comparison above to see which extras come with the option you are eyeing up.

Tesco Mobile is a strong pick if you already shop at Tesco and want your phone bill to earn Clubcard points. The mix of contract lengths suits people who know exactly what commitment they want, and capped contracts appeal to anyone wary of surprise charges. Families managing several lines will find the perks handy too. If you never shop at Tesco, the Clubcard angle matters less.

Tesco Mobile, giffgaff and Sky Mobile all run on O2's network, as does O2 itself, so coverage barely differs between them. The split is in the perks: Tesco Mobile gives Clubcard points and capped contracts, giffgaff leans on flexible rolling plans, and Sky Mobile on rollover data. Choose the reward that suits how you live.
