What does SIM-free mean?

SIM-free phones come without a contract and SIM card attached. You own the phone outright and all you need to do is find a SIM card to go with it.

The benefit with a SIM-free phone is that you pay for the phone upfront, with the only monthly cost coming from your SIM card.

Mobile phone processors

What is a processor? - The processor is your phone's brain. The better the processor, the smoother and faster your phone will run.

Processor specs - Every process has a number of cores, dual (2), quad (4), hexa (6) or octa (8), and the more it has, the smoother it can do more things at one time.

Processor speed is also important. This is measured in GHz and a faster processor is a more powerful processor.

RAM is the final piece of the processor puzzle and once again, more of it means better performance. More RAM will provide a much smoother transition when using multiple applications at once.

To get the performance you want, you need a phone with enough cores, speed and RAM to satisfy your usage. Below we've put together a handy guide to help you decide if a phone has enough power for what you need it for.

Battery and charging

Content Image

Battery size - A bigger battery often means more battery life. Battery size is measured in mAH (milli-amp hours) and is included on most of our product pages.

You can also get an idea of talk time (the time a battery last whilst you talk to someone) and stand-by time (time a battery last will last whilst on, but not in use).

How do screen quality and processing power affect battery life? Screen brightness and fast performance can sometimes place a greater demand on the battery. This means that mid-range models often have better battery life than top-of-the-range phones.

Battery saving tips

- Use Wi-Fi instead of 4 or 5G

- Use power-saver mode

-Turn down screen brightness

-Close background apps

-Turn off your location

Mobile phone storage

Mobile phones come with two types of storage: internal and cloud.

Content Image

Internal storage 
Internal is the amount of physical storage space on your phone. You can get phones with 8, 16, 32, 64, 128, 256 and 512GB of storage.

- With 8, 16 and 32GB you may find that space fills up quickly if you take lots of photos and videos.

- 64GB and 128GB phones provide ample space for even the most snappy users, with more room for apps, games and podcasts too.

-Devices with 256 and 512GB have more than enough space for all the essentials, as well as high-quality video files.

Cloud storage
Most Android and Apple phones come with a set amount of free cloud storage, through either Google Drive or the iCloud. Storing items in the cloud frees up physical storage and lets you access files from other devices.

Mobile phone camera guide

The camera has become one of the defining features of any smartphone. Here are some of the key features to look out for.

Content Image

Front camera

AKA the selfie cam. Phones usually only have one front-facing camera and the easiest way to compare quality is by MP (megapixel). More megapixels mean better quality photos.

Choose a phone with a quality front camera if you plan to take lots of selfies.

Content Image

Rear camera

The rear camera is often far more sophisticated than the one at the front. Megapixels are still important, but this where devices will pack extra tech like wide-angle lenses, telephoto lenses and enhanced zoom.

Focus on rear camera quality for better landscape and travel photography.

Content Image


All smartphones allow you to record video, but some are more suited to the job than others. Some phones can shoot in 4K and there are numerous apps that can help filmmakers perfect their recordings.

Focus on video features if you upload a lot of content to social media.

Mobile phone screen guide

The size and quality of screen you need often depends on how you'll be using your phone.

Content Image

Screen size

Over time, mobile phone screens have gotten bigger to improve video watching experience. And if you regularly use your phone for watching YouTube, TV shows or movies, then a big-screen is a must-have.

The benefits of a more compact design is that it's likely to fit more comfortably in your hand and pockets.

Content Image

Screen quality

Resolution and pixel density are the best way to determine screen quality. The higher the resolution and the more pixels per inch, the sharper the screen will appear.

For increased immersion and a greater viewing experience, choose a model with a curved or infinity screen.

Content Image

Screen protection

There's nothing worse than a cracked screen, so look out for devices that feature toughened glass, which provides extra protection against drops.

Some phones also feature shock resistance, water-resistance and even waterproofing. But before you go dropping and dunking your phone, always check the specs for the depth and distance it can handle.
