How to use your Tesco Mobile voucher
Getting a great price on your next mobile is a done deal when you do the following:
- Choose from our vouchers and discount codes by clicking the corresponding ‘See Code’ or ‘Get Deal’ prompt next to the one you’d like to redeem.
- When selecting ‘Get Deal’, there is no code featured, so click through the link to be taken to the relevant Tesco Mobile page where your desired deal/offer/promotion is in place.
- If clicking ‘See Code’, copy it once it’s visible before taking the link to begin browsing for your next phone contract.
- Once you’ve selected the phone and contract you wanted, proceed through the checkout section as normal until you reach the fourth and final sub-section - ‘Payment Details’.
- The screen should look somewhat like the one seen below, paste your voucher code in the highlighted box and click ‘Apply voucher’ to see how much extra you’ve saved before you pay.

Tesco Mobile SIM only deals
When you’re already partnered with your perfect phone, cut costs even further by snagging unlimited minutes, textas and plenty of data in a Tesco Mobile SIM only deal. Competitive packages for low data thresholds are priced as little as below £10 a month - making your phone bill a mear footnote in your monthly budget.
Tesco Mobile top ups
Whether you’re paying as you go or are working without a contract, topping up your Tesco Mobile device with extra data, time and texts is a breeze. Either buy a voucher from your local Tesco store, pick up a digital voucher or top up online to keep your social life and entertainment continuing without a hitch.
The Tesco Mobile returns policy
The return window for your device will depend on the type of contract or phone you’ve bought - pay monthly customers have a 14 day cooling off period in which they can, while pay as you go customers have this window extended to a full 30 days. Exchanges are allowed as well, though you should contact customer service when you wish to do so.
