Oppo A40

Want to keep your signal?

If you live in a place where you can only get decent signal with one network, that doesn't mean you're stuck with it, as smaller providers may 'piggyback' on that network.

Select your current provider below and we'll only show Sims that use the same network:

Since all the deals we show are for new customers, we'll automatically hide offers from your current provider. If you'd like to see them, you can select to include your network in the filters.

This means to get the price quoted, you'll have to remember to claim the cashback, often in smaller amounts over several months. As many forget to do it, we don't show these deals by default.

If you change your mind, you can amend the filter back to 'automatic only' cashback at any time.

These are usually customer returns or have been sent back due to a fault that has now been fixed.

While you won't get the original packaging and accessories, they work normally and we only include phones with the highest rating.

This is ordered by the literal total cost over the length of the contract

One-year contracts are often going to appear cheaper overall than longer deals as you're getting the airtime for a shorter period, so use equivalent monthly cost to see the real value.

This Huawei smartphone doesn't support Google apps (Gmail, YouTube, Maps or the Chrome browser) and other apps you can usually find elsewhere (banking, shopping etc) are not yet available. There are ways around this, but it's not for everyone and they won't update automatically.

Social tariffs

We'll include special social tariffs in your results that are offered to those on certain benefits - do check eligibility criteria with the provider as it varies by firm.

You don't get the original accessories

With refurbished phones, you may not get any of the original accessories the phone came with when new, such as plugs and earphones - but you'll usually get a cable to charge it.

Most offer a 12-month warranty

Most retailers offer a 12-month warranty on refurbished phones, though always check first before buying. Under the warranty, the retailer will fix most technical issues that occur during the first year you own the refurb.

Most allow free returns for up to 30 days

Retailers generally offer free returns on refurbished phones. You usually have either 14 or 30 days to return it if you're not happy (it varies depending on the retailer). It should be a straightforward process to return it in this period, as most have dedicated processes.

You can still insure your phone

Insurance providers will usually let you insure you phone even if it's a refurb, and it shouldn't cost any extra. So if you want to protect your phone against accidental damage, loss or theft, see Mobile phone insurance for more info.
