Mozillion is best known for selling both brand new and certified refurbished mobile phones at prices that tend to undercut the big high street players. If you’re after the latest iPhone or Samsung Galaxy but don’t want to pay full whack, their refurbished section is worth a look. It’s pretty straightforward, with phones tested and reset to good-as-new condition, often with a warranty included. They also offer SIM free phones, which means you’re not tied into contracts and can pick whichever network suits you.
The SIM only plans Mozillion offers are quite competitive, starting from as little as £4 a month, running on the UK’s main network infrastructure. That makes them a decent option if you want flexible, affordable mobile plans without fuss. I’d say their customer service and delivery times are generally solid, though not flawless – some reviews mention minor delays or stock issues, but nothing too alarming.
You’ll find deals on the site regularly, from discounts on brand new SIM free phones to price cuts on travel eSIMs for when you’re abroad. If you’re going to buy a phone and a SIM plan separately, Mozillion makes it easy to do both in one place. Just bear in mind that the cheapest prices usually come with coupon codes or promos, so it pays to keep an eye out.
Mozillion regularly runs discount codes that can knock a decent chunk off either phones or eSIMs. For example, right now there’s £15 off any brand new SIM free phone using code TAKE15, and £50 off the Samsung Galaxy S26 Ultra with SAMSUNG50. Always check the homepage or coupon pages before you buy, as these codes can make a noticeable difference.
If you don’t mind a phone that’s not straight out of the box, Mozillion’s certified refurbished options are worth considering. They’re tested and reset to good condition, often with warranty cover. Plus, there’s usually an extra £5 off when you buy refurbished with the CRACKING code. It’s a neat way to get a premium phone for less.
If you’re off abroad, Mozillion’s travel eSIMs are handy for data without swapping physical SIMs. Right now, you can save 10% on travel eSIMs to over 200 destinations with APRILTRAVEL, or 10% off USA, Canada and Mexico eSIMs with WORLDCUP10. Using these codes before you head off can save you money on roaming charges.
