What you get under £20 a month
Deals under £20 a month usually feature mid-range phones, older flagship models, or refurbished handsets, paired with a moderate data allowance. Brand new flagship phones can appear at this monthly price, but they often require an upfront payment or a longer contract to bring the monthly cost down. The handsets available change as networks update their offers.
Watch the total cost, not just the monthly
A low monthly price does not always mean a cheaper deal overall. A figure under £20 a month can come with a large upfront payment, or be stretched over a longer contract that raises the total you pay. Compare the total cost over the full contract to see which deal is genuinely cheaper, then check it fits your monthly budget. The live figures above show the lowest monthly and total costs for the deals currently available.
How to get more for under £20 a month
Refurbished and nearly new handsets can put a higher specification phone within a sub £20 budget, so it is worth including them if you are open to one. A slightly older flagship often costs far less per month than the latest release while still performing well for everyday use. A longer contract lowers the monthly payment, although it raises the total and ties you in for longer, so weigh that trade-off. Our data allowance guide helps you choose an allowance that fits your usage without paying for more than you need.
Frequently asked questions
Can I get a flagship phone for under £20 a month?
Sometimes, but usually with a trade-off. A brand new flagship at under £20 a month often needs an upfront payment or a longer contract to lower the monthly cost. Older flagship models and refurbished handsets are easier to find within this budget.
Do cheaper monthly deals come with less data?
Often, but not always. Lower monthly deals tend to pair with moderate data allowances, although larger allowances do appear, particularly on older or refurbished handsets. Check the data allowance against how much you actually use before choosing.
Will the price stay under £20 for the whole contract?
Not always. Several networks raise prices during the contract, so a deal that starts under £20 a month can rise above it later. Check the plan terms for any annual price increase before you buy.
Are refurbished phones included in these deals?
Yes. Refurbished and nearly new handsets often appear in the under £20 a month range and can offer a higher specification for the price. You can include or exclude them using the deal filters.
Is a lower monthly price always cheaper overall?
No. A low monthly price can hide a large upfront payment or a long contract that raises the total cost. Compare the total over the full contract, not the monthly price alone, to find the cheapest deal.
