Mobile Phone Buyer’s Guide

Mobile Phone Buying Guide: 6 Simple Steps to Buying a New Phone

You may upgrade your phone more often than your TV, but buying one is

just as big a commitment. We use our phones virtually all day, every

day. You don’t want to be stuck with a dud.

But do you need

the Samsung Galaxy S5 or would you be perfectly happy with the £80

Motorola Moto E? We’re going to look a bit deeper into the questions you

should ask yourself to find out which phone is right for you.

Our mobile phone buyer’s guide will help you decide:

  1. Whether to buy on contract or pre-pay
  2. Which platform and what size phone is best for you
  3. The features you really need and those you can live without

We’ll be

splitting the buying decision into various stages, so if you’ve already

made up your mind on one, just skip to the next step to find out more.

STEP 1: Contract vs Pre-pay? Which is best for you?Blue 4


you even start thinking about the phone you should buy, it’s worth

re-considering the different terms you can buy under. Should you opt for

a standard 24-month contract, buying a phone outright and going for a

SIM-free plan, or a low-commitment one-month contract or ‘pay as you go’


It’s not an easy choice, and you shouldn’t just assume it’s best to carry on with what you’re currently doing. For example, if you like to change your phone often then buying your phone and selling it when you want a new one is better than being locked into a contract. Moreover, contracts aren’t great value when you look at them properly.

Is a contract really good value?

demonstrate, we’ll look at the real cost of a contract. One of the main

attractions of a contract is that it subsidises the otherwise-scary

cost of a high-end phone. Mobiles like the iPhone 6, Sony

Xperia Z2
and HTC One M8 can cost up to around £550 on their own, where

there will often be no up-front cost on a higher-end contact.


you need to consider how much the line rental will cost you over the

period of the full contract – usually two years. A £35 a month contract

over two years will cost you £840, and there’s usually no option to

re-negotiate your deal in that time unless you want to spend even more

cash. By contrast, a SIM-only £12 a month deal will cost you just £288

over two years, and you’re often not tied into a long contract. The

difference in cost is the entire cost of a high end phone (£552 to be


At this point, being a bit commitment-phobic

isn’t too bad an idea, because the roll-out of 4G internet is seeing a

repositioning of how much data we’re getting on our contract deals. And

some of the most generous data-heavy deals are on SIM-only tariffs.


offers ‘all you can eat’ data from just £15 a month, GiffGaff from a

mere £12 a month as part of its zero-commitment Goodybag scheme.


at what you need to spend to get this sort of data package when a

phone’s part of the deal, we checked out Three’s iPhone 5S contracts. To

get an ‘all you can eat’ data deal, you need to spend £41 a month – a

real high-end contract.
The downside of buying outright, though, is that you

need to, well, buy a phone outright. If that’s going to be an iPhone 6

or Samsung Galaxy S5, it’s a fair old wedge. We’ll be looking into some

more affordable options to buy outright later. The lowest entry-level

option we’d recommend at present is around £80.


Consider networks other than the ones you’ve heard of before. The main

ones are Vodafone, EE (Orange/T-Mobile), O2 and Three, but little guys

like GiffGaff, Tesco Mobile, Virgin and Lyca

Mobile piggy-back on larger networks and often offer great deals.

STEP 2: Decide which platform you want to use

Hopefully you have some idea now whether you want a standard contract, or are

willing to buy a phone outright. There are benefits to each approach.


we need to start looking at the kind of phone we’re after. But we’re

not starting with hardware. Software is actually more important. First

of all, you need to pick a platform.

These days, there are three

main platforms to consider: iOS, Android and Windows Phone. BlackBerry

used to be a contender, but simply isn’t anymore. New BlackBerrys are

rare and we have no faith that the system will continue to be

updated in a significant way.

Which of the big three is right

for you? iOS still offers the best selection of apps and games, but it’s

the priciest of the three. If you want a relatively recent model, the

lowest you can go is an iPhone 5 or iPhone 5C. And they still cost

hundreds of pounds. Unless you buy one that’s scratched to death from

Who has the biggest app store?

In July 2014, Android app store Google Play reached 1.5 million apps.

In June 2014, the Apple App Store hit 1.2 million apps. In August 2014,

Windows Phone’s Marketplace reached 300,000 apps.

With Windows Phone or Android, the

starting cost is far lower. Decent Androids start at £70-80 and the

entry point for Windows Phone is even lower if you opt for the old-but-decent

Lumia 520.

For most people who haven’t bought into the Apple

ecosystem, Android is probably the best all-round system. These days

it’s fairly easy to use, and slick as long as you pick the right phone.


specific appeal of Windows Phone, on the other hand, is its style. It has a distinctive

look and feel. Check out our video review of the Nokia Lumia 930 to see

what the last Windows Phone 8.1 version looks like.


Phone is also more consistent than Android across phones. Android can be

very easy to use, but some manufacturers spoil it with wonky custom

interfaces – they aim to put a maker’s stamp on a phone, but end up

making it worse. There are no such custom interfaces with Windows Phone.

While great to use, Windows Phone doesn’t quite have the apps

and games selection of Android or iOS. There are hundreds of thousands

of bits of software on the Windows Marketplace, but it’s still

poorly-stocked compared with the other big two.


the figures, iOS is the apps and games winner. Google Play has managed

to surpass Apple in term of sheer number of apps because Google’s

restrictions on letting apps into the store are much more relaxed than

Apple’s. In other words, there’s a lot more rubbish on there.

STEP 3: Decide what size phone you wantBlue 4

Picked a platform? We now need to consider the size of phone you want. Phones are generally getting larger, as shown by the new 4.7-inch iPhone 6 and the 5.5-inch iPhone 6 Plus.


Phone and Android offer screens from around three inches all the way up

to 6-plus inches. There are also phone-tablet hybrids, which offer call

features in what is essentially a 7-inch tablet.

Why should you buy a 4-inch phone? The smallest smartphones around have around 4-inch screens, and they often some of the cheapest. Phones this small are, predictably enough, perfect for those with smaller hands, or children.

It’s not just about the size of your hands, though. If you’re not keen on apps or games, and don’t regularly browse the web on your phone, there’s often no need to go any larger than this size. 

Why should you buy a 5-inch phone? Is bigger better? For

things like 3D gaming and watching films, absolutely. However, there’s

also the more practical day-to-day use to consider. Having used most of

the phones released in the last year, we find that the tipping point is

around five inches.

Most adult-size hands will be able to use

the latest 5-inch phones without too much of an issue (less so with

older models, as they’re thicker and wider), but anything bigger may be

that bit too hard to use for many.
Galaxy S5
For many people, a phone between 4.5 and 5.1 inches is the perfect combo of portability and a display that’s good for browsing, gaming and more.

Why should you go larger than five inches?
A 5-inch screen is by no means the ceiling on size.

You might want to consider an even larger phone if you’ll often want it to essentially double up as a tablet. Like watching TV episodes while you’re at the gym? Or have a long commute you need to fill?

Even if a display isn’t any sharpner, larger size is generally always better in these sorts of situations.

Of course, there is another

We find that a 4.5-inch phone plus a low-cost tablet like the

Google Nexus 7 makes a fantastic combo. There are no issues with

handling the phone, and you can have a tablet stashed in your bag for

when you end up stuck on a train for an hour. Low-end tablets generally

have a lot more storage than low-end phones too.

Did you know?

Just a few years ago the top-end phones were smaller than even

entry-level ones of today. 2010’s HTC Desire, the top Android at the time, had a 3.7-inch screen, and

we thought it was massive back then. It just shows you’ll probably get

used to a larger phone in no time.

STEP 4: Decide on features you really need and wantBlue 4


we’ve given you a few ideas about which phones you should consider

buying. However, before whittling down your final options, you need to make sure your new phone is going to be in-line with your priorities. Here are a few little things to consider, especially if you’re buying on a budget.

Care most about cameras?
These days every phone has a camera, but all phone cameras are not equal. Anything but.

To get the best phone camera, make sure it has autofocus or you’ll find it quite limited. If you’re keen on the odd selfie or are buying for a teenager, you’ll make to make sure it has a front-facing camera. Some phones leave this out.

Megapixels tell you the resolution of a camera, not how good it is, but generally speaking most phones cameras of eight megapixels or above are quite good.

Care most about screen quality?
If screen quality is your top concern, we recommend making sure your phone has an IPS or OLED display. These are screen technologies that pretty much ensure a fairly good screen experience. These details should be available on the product page of a phone maker’s website.

For a real top-end screen, you’ll want one with at least 1080p resolution. Having a phone with the same resolution as a 50-inch TV used to seem crazy, but now it’s a norm among more expensive phones. These days you only need to spend about £280 to get such a screen, though.

Care most about ease of use? Lets head back to operating systems for a moment. Apple’s iOS is one of the simplest operating systems to use. iPhones are well known for keeping customisability to a minimum but that might not be a bad thing for you. If you like things that work without a lot of faffing around then an iPhone could be right for you. Android has got a lot better but can still be fiddly while Windows Mobiles also offer a reasonably easy user experience.

If you largely just want a phone to be a phone, battery life is key. A phone that lasts longer off a charge is simply easier to live with and if all you do is phone and text then a cheap Nokia feature phone that lasts for weeks on one charge might be right for you. Alternatively Doro offers a range of phones designed with ease of use in mind. their feature phones are good and come with big clear buttons, just steer clear of their current crop of smartphones.

Phone batteries are measured in milliampere-hours, usually displayed as an mAh figure. In a 4-4.5-inch phone look for one with at least 2,000mAh. For a much larger phone, though, you want to get as close to 3,000mAh as you can.

Want a phone that can handle music and films? Other than having a big screen, there’s one thing a phone must have in order to be a real multimedia jukebox – a microSD memory card slot.

Very few phones have enough memory to store a big collection of films, and those that do – like the 128GB iPhone 6 – are usually very expensive.

What should be on your checklist? You can

assume that any smartphone is going to have things like GPS, Bluetooth

and Wi-Fi, but other features are not things you can rely on being in

every phone. Here are the other bits and bobs you might want in your

next phone.

This is a short-distance wireless

communications standard. It sounds pretty boring, but it can be very

useful. Lots of more recent wireless audio docks and headphones use it

to pair up, before using Bluetooth to transmit audio. You can also use

NFC to buy some items on the high street, using the right app. NFC is

not essential, but it’s a neat extra missing from many cheaper phones. Blue

The big one to consider is 4G. This is the new (ish) generation of

mobile internet, and its capable of speeds much, much quicker than most

people’s home broadband. In the real world, you’ll see day-to-day speeds

between about 4Mbps and 10Mbps, where the average for 3G is about

2Mbps. Your contract/network deal needs to be 4G capable too, but

there’s actually not that great a premium to pay for 4G phones these

days. And it’s only going to get better. Blue
Icons 2Optical image

Phones have really quite small camera sensors – this is

the thing that actually ‘makes’ a camera’s photo. To compensate, some

phones use optical image stabilisation, which helps to improve image

quality in low light. OIS makes a phone much better at taking low-light

photos without the help of a flash. It’s not essential, but it’s worth looking for if you’re camera fan.Blue
Icons 3IR transmitter: An IR blaster or transmitter is a wireless

signal sender that uses the same technology as the remote control for

you TV or Blu-ray player. It lets you phone act as a universal remote,

with the help of an app (one usually comes preinstalled in phones with

this feature). It’s more of a ‘nice to have’ than a ‘must have’.Blue
Icons 4Fingerprint scanner: A few phones use fingerprint

scanners, letting you take them out of standby without any awkward

passwords. The best fingerprint scanner on the market at present is the

iPhone 5S and iPhone 6. The Samsung Galaxy S5 has a reasonable one too, although

it’s a little more fiddly. Blue
Icons 1Camera flash: If you’re buying quite a

cheap phone, you need to consider whether you’ll need a camera flash or

not. Some low-cost phones leave this feature out. It’s a must if you

want to take photos of people late at night, especially in a cheaper

phone whose camera isn’t going to be all that great in any conditions. Blue
Galaxy S5 frontFront

Another sacrifice of some lower-cost phones is a front


also known as the selfie cam to some. It’s not a feature we personally

find a day-to-day essential, but it certainly is to some. Some recent

phones even offer quite high-quality 5-megapixel front cameras for

super-selfies. Blue
microSDmicroSD card slot:

Many phones let you expand their internal storage using a memory card, a

microSD card to be exact. If you want to watch films or use your phone

as a music player, it’s a good idea to get one with expandable memory.

Memory cards are generally much cheaper than buying a phone with more

storage, and capacities go up to 128GB.
Sony Xperia Z2Water resistance: Some phones like the Galaxy S5 or Sony Xperia Z3 offer water and dust resistance up to a certain level. If you like using your phone on the beach or in the bath you might want to consider this feature. Unfortunately its mainly limited to more expensive phones at present.

STEP 5: Decide on your budget
Blue 4


much do you want to spend? You need to spend a lot of money to get an

iPhone, even a second-hand one. If it’s an iPhone you must have, you’re

going to have to forget buying budget.

We also don’t recommend

buying a very old iPhone, such as the iPhone 4 or iPhone 4S. The latest games

often leave out older models like these, which is frustrating, and iOS 8 doesn’t run very well on these older phones. An iPhone 5 or iPhone 5C is the oldest iPhones we’d recommend.

For Android and Windows Phone mobiles, though, there’s a huge breadth of budget choices. Let’s take a look at them.

TrustedReviews Recommends: Budget PhonesBlue 4


budget picks for each system start at between £70 and £80. We recommend

buying these sorts of devices outright, but on a contract you’re

looking at a monthly payment of around £12-13. That’s not too different

to a SIM-only deal, but you’ll generally be tied into a lengthy contract

as usual, and the terms normally aren’t as good.

Motorola’s budget wonder is our top budget phone. You get

near-vanilla Android, a good processor and a great 4.5-inch screen for a very

attractive price. The camera’s only so-so, but other than that this is a

real star phone. We recommend the 4G version, which costs around £150. If you prefer a larger screen and better camera, also consider the 5-inch Moto G 2. It has 5-inch screen, but it doesn’t have 4G.Blue
Phone picturesMotorola Moto E: Android For Even Less


has released an even lower-cost brother to the Moto G, the Moto E. It

costs around £20-30 less, has a smaller, less sharp screen and a worse

camera. But it still gets the basics right enough to earn a hearty

recommendation. It’s the budget phone that shows Sony and Samsung how

low-cost phones should be done. Blue
Phone pictures 5Nokia Lumia 520: Best Cheap Windows Phone


oldie but a goodie, the Nokia Lumia 520 can be had for just £60 these

days, and it’s still a good Windows Phone handset. You even get some

features missing from many more expensive budget phones – an IPS screen,

an autofocus camera and a decent amount of storage (8GB). It’s actually better than the Lumia 530 that’s replacing it. Grab it

before it falls off shelves.Blue
Phone pictures 11EE Kestrel: Best 4G Phone Under £100

A phone

branded with the name of a network? Quite a few low-cost phones are

positioned like the EE Kestrel. It’s actually made by Huawei. It’s pretty good

too. You get a pretty fast Snapdragon 400 processor, a decent IPS screen

and 4G, all for under £99. The software is a little bit quirky, but

it’s a real bargain.

TrustedReviews Recommends: Mid-Range Phones
Blue 4

Want a bit more than you can get from a

true low-cost phone? Spending a bit more will usually get you more

power, a larger screen and a much better camera. If there’s one place

low-end phones generally fail, it’s camera quality.

When looking

at mid-range phones, it’s absolutely worth checking out last year’s

lead mobiles. They’re often available for the same price as this year’s

middle-ground ones, but tend to offer better screens and performance.


these phones we’re looking at between £200-300 spend, or around £20 a

month on contract. Here’s where contract phones can be pretty

attractive, getting you a phone that feels high-end without too big a

monthly cost.

New mid-range Windows Phones, such as the Lumia 730 and Lumia 830, are coming soon but we haven’t reviewed them yet.

Phone pictures 2Nexus 5: Best Pure Android Phone


Nexus range of phones tends to offer fantastic value for money, as well

as the quickest access to the latest Android updates. The Nexus 5 is still one of

our favourite phones. The 5-inch Full HD screen is fantastic and

performance is great. The camera isn’t fantastic and battery life is not

as good as some, though. Also, if you’re considering it, it’s worth waiting a month or so as a replacement is rumoured.Blue
Lg G2LG G2: Best Nexus 5 Alternative

LG’s big-hitter

from 2013 is the LG G2. However, as it turned up quite late in the year

it’s not actually that out-of-date, specs-wise. You get a 1080p screen, a

decent 12-megapixel camera and a Snapdragon 800 CPU. Not bad for £280.

What’s wrong with it? You might not love the quirky design, which plonks

the volume and power buttons on the back rather than the side. On the insider it’s basically the same as the Nexus 5, but it has better battery life. The downside is less regular updates. Blue
Phone pictures 7Sony Xperia Z1 Compact: Best 4-inch Android


it was originally released, the Sony Xperia Z1 Compact was a

revelation. At the time it was a phone with real high-end specs, but a

relatively small 4.3-inch screen. No other phone at the time

tried the same trick. We loved it. Fast forward to now and there

are slightly faster phones out there, but the Compact can still spar

with the best. And it has come down in price a bit, making it all the

more attractive. We’d pick it over the more expensive, and newer, Z3 Compact as there isn’t much difference between the two.

money to burn? There are plenty of options right up at the top of the

phone market. What you get with these tip-top phones is generally a

better camera, a faster camera and, in most cases, a better screen.

Phone pictures 14Samsung Galaxy S5: Top Android Phone


big daddy of the smartphone world, the Samsung Galaxy S5 is a force to

be reckoned with. It has a great 16-megapixel camera, a lovely Full HD

OLED screen and a powerful processor. The design is a bit odd, though,

and the software can cause a little lag despite the super-powered CPU, but it’s still one of the best phones on the market. Also consider the HTC One M8 if you prefer a stylish, metal phone.Blue

has become a master at offering real high-end phones for less cash than

the competition. This is also the first phone we’ve seen with a QHD

screen – that’s the equivalent of four 720p screens stacked together.

The screen is extremely sharp. The camera isn’t quite Galaxy S5-grade,

but it’s still good. Blue
iPhone 6iPhone 6: Our Pick of the iPhones

The iPhone 6 is not the largest iPhone ever now we have the 5.5-inch iPhone 6 Plus, but its 4.7-inch screen is a big step up from the 4-inch iPhone 5S. The screen isn’t full HD, but it’s still one of the best screens on any phone. Only the OLED screens from Samsung can top it. Improved battery life and a new, curvier design are highlights, but the camera is faster still and performs better in low-light, too. iOS 8 adds loads of useful, new features as well. 

Phone pictures 6Nokia Lumia 930: The Best of Windows Phone


Nokia has made sure its top Windows Phone mobile is a good deal cheaper

than the tip-top Android competition. Windows Phone still doesn’t have

quite the draw of Android. In exchange you get a seriously well-made,

colourful phone with a very accomplished camera. If you’ve fallen in love with Windows Phone, it’s the phone to have.

STEP 6: Make a shortlist and find the best deal


picked your platform, chosen a size, decided how much to spend and

found a few features you don’t want to live without. Now it’s time to

make a shortlist.

perhaps 2-3 phones that seem to fit the bill. Now it’s time for us to

find a deal.

Ten poundsWhen buying SIM-free, you need to shop around just

as you would for anything else. Places to check out for good deals

include Carphone Warehouse, Tesco and the online stores for

the major networks. Amazon occasionally offers good prices for the

higher-end phones, too.

Negotiating contracts is a rather more

involved affair. Phone up your current network and tell them you plan on leaving is sure to see them offering you all sorts not to go. And occasionally

you’ll get a better deal than other networks could offer. If you’re

happy with the service, there’s no shame in sticking around.


are numerous services online that you can use to compare mobile phone

deals, and places that effectively aggregate mobile deals, too. Try our mobile phone comparison shop to start comparing deals from UK networks.

Other things to consider

How to keep your existing number

you decide to switch networks, whether you’re on a contract or not, you

need to get your PAC code in order to keep your number on your new SIM.

You can’t use the same SIM when you switch networks.

To get the

PAC code, get in contact with your network’s customer services

department. Once you have it, you should be able to find an article on

the network you’re switching to on how to keep your number when you

switch to the network.

This is all you really need to worry

about, as your contact information is generally linked to the digital

accounts most of us hold already – email accounts, social networks and

so on.

What size SIM card your phone needs
There are currently three sizes of commonly-used SIM cards. If you’re a long-term mobile user, the one you started with is probably not the most common one today.

Most new phones use microSIMs, while a handful including the iPhone 6 use the even smaller nanoSIM type. Only a few very low-cost phones use full-size SIMs these days. If you need to get hold of a new SIM, just get in contact with your phone network. They’ll usually be able to supply one for free.
