Nothing SIM-free Phones

Nothing SIM-free phones bring the brand's signature transparent design and Glyph lighting to phones you own outright, with no contract and no network lock-in. Buying unlocked means you can pair your Nothing phone with any UK SIM-only deal or drop in a local SIM when you travel, while still enjoying standout features like bright 120Hz AMOLED displays, a clean and bloat-free Nothing OS and capable camera systems led by the Phone (3a) Pro's 50MP periscope telephoto.

Whether you're a commuter who needs a screen that stays readable outdoors, a frequent traveller who values SIM flexibility or a professional looking for multi-day battery life, there's a Nothing phone to suit.

And when you buy from EE, you're choosing a device backed by the UK's most reliable mobile network, named the UK's best network by RootMetrics for a record-extending 13 years in a row, with 5G covering more than 90% of the UK population and 5G+ connectivity now reaching more than 50 million people.

Things to consider

Before buying a Nothing SIM-free phone, it's worth weighing up a few key factors to make sure you pick the right model based on your needs.

1. SIM-free versus contract: which suits you?

A SIM-free phone is bought outright and owned from day one, with no monthly phone instalments tying you to a network. You then pair it with any SIM-only deal, giving you the freedom to switch networks or plans whenever you like. If you prefer to spread the cost, EE Finance lets you pay over 3 to 48 months at 0% APR (terms apply), so you can still own the phone outright while managing your budget.

2. Camera capability: do you need pro-level zoom?

The biggest difference between the Nothing Phone (3a) and Phone (3a) Pro is the camera. The Pro adds a 50MP periscope telephoto with 3x optical zoom and up to 60x ultra zoom, plus a 50MP selfie camera, making it the stronger pick for photography enthusiasts and content creators. The standard Phone (3a) still delivers a capable 50MP main and 50MP 2x telephoto, which is plenty for everyday snaps and social media.

3. Display and outdoor readability

Both models share a 6.77" AMOLED display with a 120Hz refresh rate and peak brightness up to 3000 nits. If you spend a lot of time commuting or working outdoors, that high brightness keeps the screen readable in direct sunlight and the smooth refresh rate makes scrolling and gaming feel responsive.

4. Battery life and charging speed

The 5000mAh battery delivers a full day of typical use, stretching toward a second day with lighter use. When you need a top-up, 50W fast charging takes the battery to 50% in around 19 minutes and fully charged in about 56 minutes, ideal for busy schedules or travel.

5. Software experience and longevity

Nothing OS is built on Android and designed to be clean, fast and free of bloatware. Both the Phone (3a) and Phone (3a) Pro come with 3 years of Android OS upgrades and 6 years of security updates, so your phone stays current and secure for years without needing an early upgrade.

6. Build, design and the Glyph interface

Nothing's transparent back panel and Glyph LED interface are what set the brand apart visually. The Glyph lights signal notifications, calls and charging status without you needing to pick up the phone and you can customise patterns for different contacts and apps. Build quality combines a glass back with a textured plastic frame and IP64 water and dust resistance, so it handles daily wear well.

7. Network compatibility and travel use

Because Nothing SIM-free phones are unlocked, they accept any compatible UK or international nano-SIM. That makes them a practical choice for frequent travellers who want to drop in a local SIM abroad or for anyone who wants to keep their existing SIM-only plan and simply replace the phone.
