The retailers featured on this page may compensate us when our readers follow links to their websites and make a purchase. More

We take you through the best UK mobile providers to take a phone deal from, if you know you want to upgrade more than once every 24 months. Last updated: 2nd October 2024.

The best types of deal for upgrading early

Phone contracts based on finance let you upgrade early

Fixed sum loan agreement

You get a loan to pay off your phone

If you’re the type of person that wants to stay free to upgrade to a new phone whenever you want, you’ll prefer finance-based phone contracts. These are where the network effectively gives you a loan to buy a phone off them.

These kinds of contracts let you pay off your whole loan whenever you like, to upgrade before the end of your contract. You won’t incur any early termination fees, as you just pay back what you owe for the phone.

Some networks let you upgrade at any point, while others will require you to wait a little while. Also, some networks let you leave your usage contract (mins, texts, data) after upgrading and others don’t.

In this guide, we go over all the networks that let you upgrade early and rank them based on which ones let you upgrade the soonest, which ones let you leave your usage (SIM) contract and which ones offer the best deals.

The best early phone upgrade schemes

Joint 1st: VOXI’s early upgrade scheme is very flexible

What we like:
Green plus sign Upgrade any time during your contract
Green plus sign Flexible 1-month usage plans (SIMs)
Green plus sign Great value overall prices

What we don't like:
Red minus sign No trade-in scheme

VOXI are a sub-brand of Vodafone and despite being a lower-cost network, they offer the latest phone models on finance agreements. The great thing about these is that you can upgrade at any point during your contract.

Your loan will be managed via PayPal credit, not by VOXI themselves. So when you take your phone contract on VOXI you’ll be redirected to PayPal to sign the agreement. It’s just worth knowing before you sign up.

Once you’ve paid off the cost of your phone you can also leave your usage plan at the end of the month. This is because all VOXI’s usage plans are on flexible 1-month deals that you can switch or leave when you like.

The only downside is that you can’t easily trade in your old phone to clear your loan and upgrade that way. But you can probably get more money just selling it anyway. There’s a lot to like with VOXI’s upgrade scheme.

Joint 1st: giffgaff also let you upgrade at any point

What we like:
Green plus sign Upgrade to new phone whenever you want
Green plus sign Great value on phones and usage plans
Green plus sign Very flexible 1-month usage plans
Green plus sign Move plans up or down whenever on 18-month contracts

What we don't like:
Red minus sign Their trade-in scheme is lacking

giffgaff are a sub-brand of O2 and also offer a very flexible upgrade scheme for their phone contracts. They have some of the best value phone deals of all networks too, with most of the newest models available.

Their finance-based phone contracts are made via a third party called Klarna. They let you pay off the entirety of your loan at any point during your contract, meaning you can upgrade to a new device whenever.

You can take either a 1-month or 18-month usage plan (SIM). giffgaff’s 1-month deals let you leave when you like, while their 18-month contracts tie you in for a longer time but still let you switch plans month to month.

We would caution that trading in your phone won’t necessarily get you as much for your device as selling privately would though. But Apart from that, giffgaff’s early upgrade scheme is among the best.

2nd: Tesco Mobile’s early upgrades offer brilliant flexibility

Anytime upgrade flex

Pay off your phone to upgrade earlyHow it works

(opens in new window)

What we like:
Green plus sign Pay off your loan when you want
Green plus sign Change your usage plan whenever
Green plus sign Get even better value with Clubcard prices

What we don't like:
Red minus sign No short term usage contracts
Red minus sign No swap in scheme to upgrade early

Like the networks above, Tesco Mobile let you upgrade at any point during your phone contract. They tend to offer good value on lots of different phone models, old and new. The SIM part of your deal’s well priced too.

There’s no way to trade in your phone to wipe away your loan, but that’s not a huge downside. Tesco’s scheme is very flexible and they offer even better value to Clubcard holders (read their guide here).

And Tesco give you the flexibility to change your usage plan each month. If you want more data in the middle of the month you can upgrade it right away, but moving it down will take a month to come into effect.

This is great as you can set your usage plan to your budget. And once your phone is paid off you’re free to leave your usage contract. But leaving before your loan is paid off will incur an early termination fee.

3rd: Sky offer flexible upgrades after your first month

Swap24 Swap12

Swap in your phone to clear your loanHow 'Swap' works

from Sky's guide
(opens in new window)

What we like:
Green plus sign Get the flexibility to upgrade early
Green plus sign Good value on phones and usage contracts
Green plus sign Switch your usage plan up or down each month
Green plus sign Flexible credit agreements

What we don't like:
Red minus sign You have to wait a month to upgrade
Red minus sign No short term usage plans
Red minus sign Their Swap scheme isn’t a great choice

Sky are next on our list for the sheer value they offer on their phone deals and the flexibility of their usage contracts. They are the first network on this list where you can’t upgrade right away, only after 31 days.

In fairness, we can’t imagine most people will want to upgrade within the first month of getting a phone anyway. If you want the newer phone just join on that one. So this shouldn’t really be a deal breaker.

Sky are almost always the lowest cost option to join on a phone deal with no upfront costs. And their usage contracts let you switch your plan up or down each month so you can better suit it to your budget.

But you have to stay on your usage plan for your full contract. Also Sky let you trade in your phone to upgrade, but you can only do this in your last 12 months. Sky aren’t the most flexible choice, but are an excellent value option.

4th: O2’s prices are often higher but you can upgrade early

O2 custom plan builder

Flexible contracts with Custom plansHow they work

at O2.co.uk
(opens in new window)

What we like:
Green plus sign Upgrade at any point during your contract
Green plus sign Move your usage plan up or down each month
Green plus sign You can leave your usage contract after upgrading

What we don't like:
Red minus sign Phone deals are quite expensive

O2 are the first of the main networks on this list. They offer flexible upgrade options on loads of phone models with their Custom plans. You can pay off your loan at any point to join on a new phone.

On top of that, O2 let you switch your usage plan up or down whenever. And your usage plan is on a monthly rolling contract, meaning once you’ve paid off your phone you’re free to leave O2 altogether.

The main downside in our eyes is the price. O2’s prices for their phones are decent enough but their more-expensive usage plans (SIMs) bump up the total cost of your deal above competitors.

O2 also have a trade-in scheme, but it’s only offered as a premium extra, not as standard. We go into it in more detail in a separate section below. Overall, O2 are a flexible option for upgrading early but always compare prices.

5th: Three now let you upgrade to a new device at any time

Three Your Way

at three.co.uk
(opens in new window)

What we like:
Green plus sign Pay off the cost of your phone whenever
Green plus sign Good value on phones and usage plans

What we don't like:
Red minus sign No short term usage contracts (SIMs)
Red minus sign Trading in isn’t a great option
Red minus sign Can’t move to a smaller usage plan mid-contract
Red minus sign Some cheaper, older phones not on early upgrade contracts

Three are another of the main UK networks and tend to offer the lowest prices of the four. They offer good value on phones and on usage plans that let you upgrade to a new device at any point during your contract.

They offer all the latest devices, which is great for upgrading. And you can trade in your old phone for money off a new one. This can be useful but you might be better off selling it elsewhere.

The main downside is that they don’t offer any flexible 1-month usage plans (SIMs), so once you’ve paid off your loan you’ll be stuck on your usage plan until the end. And you can’t switch to a smaller plan mid-contract.

Also, some of their phones are only offered on traditional 12 or 24-month contracts that aren’t based on finance, so have no early upgrade feature. It’s worth checking the device you want before joining, but otherwise Three’s scheme is decent.

6th: EE offer a good upgrade scheme but at high prices

Device credit agreement

Pay off your loan at any pointSee all phones

at ee.co.uk
(opens in new window)

What we like:
Green plus sign Upgrade at any point during your contract
Green plus sign Trading in your old phone can be a decent option

What we don't like:
Red minus sign Very expensive phone contracts and usage plans
Red minus sign No short term usage contracts
Red minus sign Very inflexible usage plans

EE are another of the main four UK networks. They offer lots of devices on finance agreements that give you the flexibility to upgrade at any point during your contract (they call it “Flex Pay”).

They’re partly this low on the list as their phone deals are some of the most expensive of all networks. The bigger the loan you have to pay off, the harder it is to upgrade to a new device.

And even if you do upgrade, you’ll still be on your usage contract for at least 24 months. There are no flexible 1-month plans and there’s no way to move to a smaller plan if you’re paying too much.

EE do offer a trade-in scheme, almost as a consolation for their high prices. This can get you some decent money off when upgrading to a new device, but we think you can get more for your phone elsewhere.

7th: Vodafone are a bit less flexible but worth considering

Vodafone EVO gives you flexibility

Upgrade after your second monthSee all phones

at vodafone.co.uk
(opens in new window)

What we like:
Green plus sign Flexible upgrades after the minimum period
Green plus sign A good trade in scheme for money off a new phone

What we don't like:
Red minus sign You can only upgrade after two months
Red minus sign Very expensive phone and usage contracts
Red minus sign No flexible 1-month usage plans
Red minus sign No way to move to a smaller usage plan

Vodafone are the last network on this list due to the fact that you can only upgrade after your second month on one of their EVO phone deals. But, we can’t imagine most people will want to upgrade that early anyway.

However, they are one of the most expensive networks for phone contracts. So even when you’re able to upgrade you’ll still have a lot more to pay off than on some of the networks above.

Once you’ve upgraded you’ll be stuck on your usage plan until your 24-month SIM contract is over. Again, Vodafone’s usage plans are quite expensive and there’s no way to move to a smaller plan during your contract.

You can trade in your device to get money off your new phone or get it put right into your bank account. Vodafone are decent choice if you want to upgrade early, they’re just behind the other networks for this.

How O2’s Switch Up plans work

The best trade-in scheme for flexibility but at a cost

O2 Switch Up

Trade in to wipe away your loanHow it works

at o2.co.uk
(opens in new window)

O2 have a unique scheme called Switch Up that lets you trade in your old phone to upgrade to a new one right away. You can do this after being on your contract for 90 days if your phone is in good enough condition.

Usually when networks have trade-in schemes they only pay back part of the cost of your phone or make you wait until you’ve paid off most of your loan (like Sky). O2 wipe away your whole loan when you trade in.

There are some downsides, however. The first is that you can only do this if you have Switch Up as an Extra. To get this you either have to pay for a premium Plus Plan or add it to your contract for an extra cost.

And your phone has to be in good condition or they won’t accept it at full price. We’d like to see other networks experiment with similar schemes, as it makes trading in more appealing. But we don’t like the extra costs on O2.
