Best for most people - Lycamobile - 10GB for £5 per month with the first month £2.50

Upfront Cost: £0.00

Cost of first month: £2.50

Ongoing monthly cost: £5.00

This is the best deal for most people because:

The average data use in the UK is 9GB per month.

It's a good idea to have an allowance higher than that because running out of data is expensive.

You can also use your data in many destinations abroad including the EU & India.

This deal comes with 1000 UK minutes and 1000 UK texts per month, this is enough for most people.

The average person in the UK uses 210 minutes and 30 texts per month.

WhatsApp and similar messaging apps use your data allowance rather than texts.

The closest equivalent deals are:

50GB for £8 with Smarty

10GB for £8 with Asda Mobile

There are also some cheaper deals worth considering if you know you're a very low user.

But bear in mind that these data allowances are lower than the UK average use:

5GB for £5 with Lycamobile with the first three months only £2.50

5GB for £6 or 8GB for £7 with Smarty

The closest equivalent deals from the big four networks (EE, O2, Three, Vodafone) are:

12GB for £22 (price increases by £1.25 every April) or 4GB for £7 (price increases by £1 every April) with Three

20GB for £26 or 5GB for £23 with O2 (price increases by RPI+3.9% every April with both deals). Data allowances doubled to 40GB and 10GB if you're a Virgin Media customer

20GB for £34, 8GB for £29 or 3GB for £26 with Vodafone (price increases by £1.80 every April with all deals)

Best for heavy users - Lycamobile - 88GB for £8 per month

Upfront Cost: £0.00
