How to Top Up Tesco Mobile Pay As You Go

Tesco Mobile is a UK mobile virtual network operator (MVNO) that runs on the O2 network, jointly owned by Tesco and Virgin Media O2.

Tesco Mobile PAYG Min top-up £10 Updated May 2026

Tesco Mobile is a UK mobile virtual network operator (MVNO) that runs on the O2 network, jointly owned by Tesco and Virgin Media O2. That means PAYG customers get the same coverage and 5G footprint as O2, but with Tesco Mobile's own pricing, customer service and the network's biggest selling point: full integration with Tesco Clubcard. You can earn Clubcard points on top-ups bought in Tesco stores, redeem points against your bill, and access Clubcard Prices on selected Pay Monthly and Rocket Pack offers - which can save a few extra pounds a month if you shop at Tesco anyway. Tesco Mobile also has consistently strong customer service ratings and won Uswitch's Best Network for Customer Service in multiple years.

Topping up your Tesco Mobile PAYG SIM can be done five ways: online at tescomobile.com, in the My Tesco Mobile app, with a top-up voucher from a UK shop (especially Tesco itself), in person at a Tesco store, or by enabling auto top-up to add credit on a schedule. Once you have credit, the most cost-effective option is to buy a Rocket Pack, which is Tesco Mobile's name for its 30-day allowance bundle of data, calls and texts. Rocket Packs come with standard PAYG flexibility plus access to Clubcard discounts and rewards. Most Rocket Packs include 5G access on supported phones at no extra cost. Credit on Tesco Mobile PAYG lasts 6 months from your last top-up, so a small top-up twice a year keeps the SIM and number active.

If you find you top up the same amount every month, switching to a SIM-only contract normally costs less for the same allowance, and Tesco Mobile's Clubcard Prices on Pay Monthly plans can take that saving even further. You can keep your existing number when you switch by getting a free PAC code from Tesco Mobile first. This guide covers every top-up method, current Rocket Pack pricing, voucher locations and the most common questions Tesco Mobile PAYG users have.

How to top up Tesco Mobile

There are five ways to add credit to a Tesco Mobile PAYG SIM. Pick whichever suits you - they all credit your number within a minute.

1

Top up Tesco Mobile online

The simplest way to top up Tesco Mobile is at tescomobile.com/topup. Enter the Tesco Mobile number you want to top up, choose an amount between £10 and £50, and pay by debit or credit card. Credit is normally applied within a minute, and you do not need to log in to top someone else up. If you have a Tesco Mobile account, signing in lets you save card details, view top-up history and choose a Rocket Pack in the same flow. Online top-up accepts Visa, Mastercard and Maestro. There is no fee, and you can top up your own number or any other Tesco Mobile PAYG number from the same page.

Top up via the My Tesco Mobile app

My Tesco Mobile is the easiest way to manage a PAYG SIM day to day. Download the app from the App Store or Google Play, sign in with your Tesco Mobile number, and tap Top Up on the home screen. You can pay with a saved card, Apple Pay or Google Pay, with credit applied straight away. The app also shows your remaining data, calls and texts in your current Rocket Pack, when it expires, lets you change Pack for next month, and gives quick access to your Clubcard balance and any Tesco Mobile-specific Clubcard offers.

Tesco Mobile top-up voucher

Tesco Mobile top-up vouchers are sold at thousands of UK shops - obviously including Tesco itself, plus most major supermarkets and convenience chains. Vouchers come in £10, £15, £20, £30 and £50 amounts. To redeem, dial 4444 free from your Tesco Mobile phone, or visit tescomobile.com/topup and enter the 16-digit code. You can also redeem in the My Tesco Mobile app under the Top Up section. Vouchers are useful if you do not have a debit card, want to give credit as a gift, or need to top up a phone that is not yours. Buying vouchers in Tesco lets you earn Clubcard points on the purchase, which is a small but worthwhile bonus.

Top up in store

Tesco Mobile top-ups are sold across the UK at almost all Tesco supermarkets, Tesco Express stores and at most major rivals like Sainsbury's, ASDA, Morrisons and the Co-op. Tell the cashier the Tesco Mobile number and the amount, pay in cash or card, and credit is loaded electronically to the SIM at the till. You can also pick up vouchers in any Tesco Mobile counter inside Tesco supermarkets. Topping up in Tesco itself usually earns Clubcard points on the purchase.

5

Auto top-up

Auto top-up automatically adds a fixed amount of credit to your Tesco Mobile PAYG number on a schedule, paid from a saved debit or credit card. You can configure it to top up monthly on a fixed date, or top up automatically when your balance drops below a threshold. Set it up in the My Tesco Mobile app or your online account under Top Up settings. You can change or cancel it at any time. Auto top-up suits people who renew the same Rocket Pack every month or use their phone mainly for emergencies.

Where to buy Tesco Mobile top-up vouchers

Tesco Mobile top-up vouchers are sold at most major UK retailers. Look for them at the till, the customer service desk, or any PayPoint counter.

Topping up Tesco Mobile every month?

If you keep buying the same Rocket Pack each month, a SIM-only contract on Tesco Mobile or another UK network usually works out cheaper. Tesco Mobile Pay Monthly plans also come with Clubcard Prices, which can save you a few extra pounds a month if you shop at Tesco anyway.

Tesco Mobile PAYG top-up FAQs

How long does my Tesco Mobile PAYG credit last?
Tesco Mobile PAYG credit lasts 6 months from the date you last topped up or used the SIM. Any top-up resets the clock for another 180 days. If you do not top up within 6 months, Tesco Mobile may suspend the SIM and eventually recycle the number, so a small top-up at least twice a year keeps everything active.
Can I top up someone else's Tesco Mobile PAYG SIM?
Yes. On tescomobile.com/topup or in the My Tesco Mobile app, enter the Tesco Mobile number you want to top up rather than your own. The credit is applied directly to their account, and you do not need to be logged in. You can also buy a voucher in any Tesco store and pass on the code so they can redeem it themselves.
What is the minimum top-up amount on Tesco Mobile?
The minimum top-up online or in the My Tesco Mobile app is £10. The smallest Rocket Pack starts at £5 and is available from inside the app. Some retailers also sell £10 vouchers as their lowest denomination.
How do I check my Tesco Mobile PAYG balance?
Dial 4444 from your Tesco Mobile phone for an automated balance update at no charge. The My Tesco Mobile app shows your balance, current Rocket Pack remaining allowance, expiry and Clubcard points balance on the home screen. You can also text BALANCE to 4444 free of charge.
Will my Tesco Mobile PAYG Rocket Pack auto-renew?
Yes, Rocket Packs are set to auto-renew each 30-day cycle by default if you have enough credit on the account. If renewal fails because of low credit, your account falls back to standard PAYG rates until you top up. You can switch off auto-renew in the My Tesco Mobile app or by dialling 4444 and following the prompts.
Can I use my Clubcard with Tesco Mobile PAYG?
Yes. Tesco Mobile PAYG customers can earn Clubcard points on top-ups bought in Tesco stores and on Rocket Pack purchases, depending on the current promotion. Tesco Mobile also runs Clubcard Prices on selected Pay Monthly and Rocket Pack offers, where Clubcard members get a lower price than standard customers.
