The best Carphone Warehouse deals in March 2025

As you might know, pay as you go (PAYG) deals don't tie you into any kind of contract whatsoever. You simply buy a phone from Carphone Warehouse and then top up your minutes, texts and data when you need it (you'll know when you've run out). You also don't get credit checked, which you do with any type of pay monthly contract. Lots of handsets are available from Carphone on PAYG deals including phones from Samsung, Sony and Motorola. View all the Carphone Warehouse pay as you go deals. 

Carphone Warehouse offers upgrades across the networks it offers on pay monthly and, what's more, you don't need to have bought from the retailer before. You can use Carphone's online upgrade checker to see if you're eligible. Some networks will even let you upgrade early.

Note that you'll need to enter all your network details into the upgrade checker so Carphone Warehouse can check with your network. So it's best to have your bill to hand.

If you plan on switching mobile phone networks, Carphone Warehouse (like all of other retailers) now operates a text to switch programme. That means that when you buy a new mobile phone contract from Carphone, you can simply text your old network to get your code and switch, making it a far easier process than before.

In a word, yes. You need to ask your current network for your PAC code (done using the text to switch method mentioned above). 

Once you've got the PAC it's valid for 30 days - so don't hang about! if it expires you'll need to get another one. 

Next, buy your new phone from Carphone Warehouse and tell them your PAC and your number will be transferred within a few days. If your new phone is on Virgin you'll need to call them directly once your phone is connected.

We all like a new phone, but if you're just stuffing your old handsets into a drawer then you're missing out, because you can get decent cash for your old handset. Carphone Warehouse offers a decent trade in scheme, with many two year old handsets still worth £200 - worth doing! Carphone will send you a packet to use to send in your handset, too. 

Check out how much your handset is worth.

If you've been extensively hunting the web for the best price on your new mobile, you may have come across Mobiles.co.uk and e2save. These two websites are part of the Carphone Warehouse family, but frequently come up with much better prices than Carphone manages itself.

Mobiles.co.uk features brilliant deals on the majority of the current flagship phones and if you enter the code 10OFF at the checkout, you'll save an extra tenner on the upfront price of the handset. e2save usually offers better value on older, budget phones - so if spending a lot on a new phone doesn't hold much appeal, click on the link above to see if they can help you out.

Carphone Warehouse is the UK's largest phone retailer. While it used to deal in all four of the main networks, it now focuses on Virgin, Vodafone. and it's own network - iD Mobile.

Originally started in a London flat in 1989, Carphone Warehouse grew to have 20 stores by 1994 and floated in 2000. In 2014 it merged with Dixons Retail to form Dixons Carphone, hence why many Currys PC World stores now incorporate Carphone Warehouse concessions. The retail giant owns the iD network. It's a virtual network that uses the Three mobile network.

Now, as of 2020, Carphone Warehouse has closed up most of its high-street stores meaning its business is almost entirely online at this point.
