One honest note: Affordable Mobiles doesn't always run a traditional on-site promo code, because so much of the saving is already in the price. If you don't see a code box on a deal, that's normal, because the cashback, free gifts and upfront discounts apply automatically, so you're not missing out.

What I like most about Affordable Mobiles is how little you have to chase. The cashback is the obvious example: with a lot of retailers you have to remember to claim it every month, and it's easy to lose money simply by forgetting. Here it's automatic and paid in one go, so the price you sign up to is the price you get.

The free next-day delivery on every order helps too, with no minimum spend to work around, and the trade-in scheme paying out the same day your phone arrives makes upgrading feel a lot less daunting. For a straightforward way to keep your phone costs down, it is well worth a look.

Shop the Summer Sale

Affordable Mobiles' Summer Sale is on now, with money off the upfront cost, free gifts and data boosts across the latest handsets. A few that stood out at the time of writing:

• iPhone 17 Pro Max (Three, unlimited data): £99 upfront, down from £299 (save £200), at £55 a month.
• Samsung Galaxy A37 5G (Vodafone, 100GB): £9 upfront with a free Galaxy Tablet, at £25 a month.
• Samsung Galaxy S26 (O2): a data boost to 400GB, at £38 a month.

Sale deals change often, so treat these as examples and check the live price before you order.

Let the automatic cashback do the work

This is the saving that sets Affordable Mobiles apart, and you don't have to do anything to get it.

• Their Guaranteed Cashback is automatic, with no monthly claim to submit and no deadline to miss.
• It's paid straight to your bank by BACS, 90 days after your order ships.
• You can see it working in the SIM-only prices: a Three Unlimited 5G SIM shows as £14.08 a month, down from £17 before cashback, and a 100GB plan at £11, down from £15. The headline price already has the cashback applied.

Trade in your old phone

Before you pay full price, it's well worth seeing what your current handset is worth.

• Get a free instant valuation by selecting your model, storage and condition.
• Pack it in any box, attach the free pre-paid label and send it off.
• You're paid by bank transfer the same day it arrives, and the Tech Price Promise means you get the first price offered, or your phone back for free.

Go SIM-only if your handset is still going strong

If you don't need a new phone, a SIM-only plan is the easiest way to cut your bill.

• Plans start from around £7 a month for 8GB, with most coming on £0 upfront and unlimited minutes and texts.
• There are 1-month rolling options too (SMARTY, VOXI), so you're not tied in if you like to switch.

Consider a refurbished handset

A refurbished phone gets you a big-name handset for less than buying brand new, which is kinder on your budget and on the planet.

Sort the deals by the biggest saving

• Beyond the Summer Sale, keep an eye out year-round for deals with money off the upfront cost, a free gift or a data boost built in.
• Filter and compare so you can find the lowest upfront cost, or the biggest overall saving, quickly.

Already a customer? Check your upgrade early

Use the free online upgrade eligibility checker to see when you can move to a newer handset; you don't always have to wait for your contract to end.

Affordable Mobiles works a little differently to a typical voucher-code retailer, so it's worth knowing where the savings actually come from.

What types of savings are available?

Rather than one headline code, the savings come in a few forms:

• Automatic cashback applied to the monthly price on selected deals.
• Money off the upfront cost of a handset.
• Free gifts (such as a tablet) and data boosts on selected plans.
• Trade-in value towards your next phone.

When are the best times to buy?

• New phone launches are often a good moment for the previous model, as deals tend to sharpen up once a successor lands.
• Major sale periods like Black Friday and the January sales usually bring the strongest upfront discounts and gift offers.

How does the cashback actually work?

It's automatic, so there's nothing to claim. The amount is the gap between the "before cashback" price and the price you see, and it's paid by BACS 90 days after your order ships.

Top Tip: if you are comparing two SIM deals, look at the after-cashback monthly figure rather than the upfront. That is what you will actually pay over the year.

Free next-day delivery, seven days a week

Every order comes with free delivery and no minimum spend, with next-day delivery available seven days a week on orders that pass the standard checks. Phones are sent with DPD on a Next Day service and need a signature; SIM-only orders come by Royal Mail. You will get tracking by text or email, and a one-hour delivery window on the day.

Shop with peace of mind

There's a bit of built-in reassurance here too:

• The price you see is the price you pay. Every upfront and monthly charge includes VAT, with no ex-VAT pricing or surprise fees added at the checkout.
• 14 days to change your mind. Return your phone within 14 days for a refund, as long as it is in pristine condition with all the original packaging and accessories.
• That £2.50 isn't a charge. It's a small amount reserved and then immediately refunded to verify your bank details (it can take up to 7 days to reappear on your balance).
