Samsung Galaxy Note 2
The Samsung Galaxy Note 2 is a slightly different offering to the other handsets on display here, with less of a focus on security, email capabilities and simple document manipulation.
With a huge 5.5-inch display and its very own S-Pen stylus the Galaxy Note 2 merges the line between smartphone and tablet.
If your business is creatively minded then you may find the accuracy of the S-Pen and the ability to draw a real advantage.
You can also annotate documents, emails and anything else on screen using the stylus, allowing you to provide instant feedback to colleagues.
Multitasking has always been tricky on smartphones, partly due to the screen size and the fact that it's not really possible to have two apps on screen at once.
Samsung has overcome this problem on both the Galaxy S3 and Galaxy Note 2, allowing you to run two apps side by side on the screen, so you could be looking at the latest financials while tapping out a quick email to the shareholders.
Of course, the size of the handset may hamper some as it isn't the most pocket friendly of devices, nor is it the lightest. Also, some of the applications, especially those designed for use with the S-Pen, are overly complicated in places.
You might be sold on Apple's iOS platform but what if the iPhone 5 is just that little too expensive?
Fortunately you can easily get hold of its predecessor the iPhone 4S, and while it has a slightly smaller display and a little more round the waist, it's practically the same phone, running the same iOS 6 software.
It's only available in the 16GB variant with no expandable storage option, which may hamper those who require more space, but you do save some serious money.
You get all the features you have on the iPhone 5 including Siri, a wealth of applications and business security including remote control, which allows a phone to be wiped remotely if it is stolen or left in a bar.
The 3.5-inch Retina display is crystal clear, allowing you to easily read text and examine charts, graphs and images without issue, while the Apple design makes for a handset which is pleasing on the eye and feels every bit as premium as the price.

Fancy a Windows Phone 8 device but the Lumia 920 is just too big? Then take a look at the slender chassis for the HTC 8X.
Touted by Microsoft as the signature Windows Phone 8 device, the 8X runs exactly the same software as the larger Nokia, all be it on a slightly smaller 4.3-inch display and a considerably more pocket friendly size.
You still get the Microsoft Office suite on the 8X and it has enough power under the hood to run WP 8 smoothly.
The Internet Explorer 10 mobile browser is pretty snappy, allowing you to browse web pages easily and the HD display ensures everything looks crisp and clear.
It's also slightly cheaper than the Lumia 920 if you're looking to save money, and the unibody polycarbonate design makes for a beautiful looking handset.

BlackBerry Curve 9320
If you like the idea of a tried and tested secure system but don't have the money for a top of the range handset, the BlackBerry Curve 9320 could be the business smartphone for you.
The Curve 9320 compromises in the storage and power departments to become more affordable, while its all plastic case won't exactly wow in board meetings.
That said, it's a perfectly capable little handset benefiting from the secure BlackBerry services and a range of connectivity options. This means you should have no trouble hooking it up to your laptop, or swapping information between NFC enabled devices.
The isolated keys on the keyboard are preferred by some, making typing even easier and quicker, and while it may not look a million dollars, it may help you make that amount.
It also sports a dedicated BBM key, giving you quick access to the free BlackBerry Messenger app – perfect if your company relies on this as an instant messenger.
There are front and rear cameras on the Curve 9320 for capturing those important moments and making key video calls, although the small screen isn't the best when it comes to reading documents or web pages.
Google Nexus 4
If you want the best features to price ratio from your smartphones then you'll need to take a look at the Android Jelly Bean running Google Nexus 4.
Manufactured by LG the Nexus 4 sports an impressive quad-core processor, 4.7-inch HD display and the latest version of the powerful Android operating system wrapped up in a package which will set you back less than £300.
The Nexus 4 is beautifully designed, has more connectivity than a BT Telephone Exchange and even excels in the simple matter of making telephone calls.
It is slightly hampered by only being available in 8GB and 16GB, and there's no 4G support, unlike the Note 2, Galaxy S3, Lumia 920, iPhone 5 and BlackBerry Z10.
Perhaps Android isn't the best mobile business solution, and the Nexus 4 lacks the additional enterprise features Samsung has added to its devices. But at such a low price it is definitely worth considering.
