There are lots of ways you can keep yourself or a friend topped-up. It’s quick, easy and you’ll collect Clubcard points when you do.

First time topping-up?

If you’re a new SIM only customer, your first top-up must be made in-store. It can’t be made over the phone or online for security reasons. After that you can top-up however you’d like.
If you’ve bought a Tesco Mobile phone online you can top-up in-store or using an online top-up.

By Tesco Mobile app

You can top-up and check your balance using our free pay as you go app. It’s available for Android and iPhone customers.
Using the app you can redeem top-up vouchers bought in store and top-up using a credit or debit card that’s already registered with us.

By phone

To top-up with your credit or debit card just call 4444 free from your Tesco Mobile device or 0345 940 0000 from a landline.

In Tesco stores

You can buy a top-up voucher from any Tesco store. The voucher is a paper receipt with a 16 digit voucher number on it.

To use a voucher, call the top-up line on 4444 free from your mobile or 0345 940 0000 from a landline. You can also use it in the Tesco Mobile app.

You’ll receive a text message confirming the top-up: ‘Top-up successful – your new balance is £xx.xx’.


You can top-up or set up a regular, auto or SMS top-up online – you’ll need to register for an online top-up account first.

Online top-up only works in the UK and using a registered UK bank account. If you have any problems registering or topping-up online, take a look at our help page.


With an E top-up card

Before you can use the E top-up card, you must register it to your mobile number – to do this text TOPUP to 28589 free from your Tesco Mobile phone.
Once you’ve registered your E top-up card you can use it to top-up at any Tesco store or in over 100,000 shops that display the green E top-up logo.

When you top-up, you’ll be given a receipt with the transaction ID. Please keep this in case there’s an issue with the top-up.

You can order an E top-up card online via My Account.
