A safety buffer or zero bill cap will give you control over your mobile bill. Your safety buffer will give you the freedom to use more than your monthly tariff if you want. And you’ll always have the flexibility to move your safety buffer up or down.

Or you can select a zero bill cap, which means that you won’t be able to spend anything above your monthly allowance. You won’t be able to do things like send picture messages, call premium rate numbers, call international numbers or use extra minutes, texts or data.

You’ll only be charged more than your tariff amount if you do things not included in your monthly allowance, such as sending picture messages, calling premium rate numbers, calling international numbers or using extra minutes, texts or data. These will come out of your safety buffer, or if you have a zero bill cap, you won’t be able to do them at all.
With a Capped contract, you’ll never be able to use more than the safety buffer or zero bill cap you’ve chosen.

It’s really up to you. Say you never want to spend more than £15 a month. Pick a £10 tariff and give yourself a safety buffer of £5. Or, if you don’t want to spend anything above your monthly allowance at all, choose a zero bill cap. The choice is yours.

Yes, you can view, change or add a safety buffer or zero bill cap in our Tesco Mobile app or My Account. You can also call us on 4488, free from your Tesco Mobile phone

We’ll text you when you’ve nearly used up your safety buffer. Then we’ll text you again when you’ve used it all up.

If you use up all your safety buffer, you can still use any minutes, texts or data you’ve got left in your monthly allowance. You just won’t be able to use any extra minutes, texts or data, or do anything not included in your allowance. You’ll still be able to receive calls and texts.

To use your phone as normal again, you can make a payment towards your bill or increase your safety buffer.

If you’re traveling in any of our 48 Home From Home destinations, you can use the data from your allowance, just like you would at home. After that, you’ll pay standard UK rates for data.

If you pick a safety buffer of £40 or less, we’ll limit the total amount you can spend on data, calls and texts abroad to £40 in your bill month.

If you pick a safety buffer higher than £40, you’re accepting that you could spend over £40 on data abroad. But we’ll still apply the total safety buffer you’ve chosen for all minutes, texts and data, whether you’re in the UK or abroad.

Before you travel, you might want to consider turning off data roaming to avoid extra costs.

When you’re buying your phone online, just tick the ‘Yes, cap my bill please’, then choose your safety buffer amount or a zero bill cap. You can change this any time in our Tesco Mobile app or My Account. You can also call us on 4488, free from your Tesco Mobile phone.
