• No one wants to find themselves short of data while on the train from London to Edinburgh where they are preparing a presentation to their board or to a client – unless they want to get fired.


• But buying a lot more data than needed is money down the drain, although it is good to have a bit more than you need as an insurance policy.


It is a fine balance – who wants to be weighed down with draconian fees for exceeding data limits or suddenly find connection slows or becomes unusable?


Free comes with a caveat


An increasing number of public hotspots across the UK can be accessed for free whether on the London Underground or in coffee shops but the security of such connections is something that everyone should think about carefully. Public hotspots are at considerable risk from hackers because


no authentication is required to get a connection. These risks can be countered using a virtual private network, Secure Sockets Layer (SSL) connections and by turning of “sharing”. To use a laptop on the move – tether it to your mobile phone,


using its 4G connection where available and, in the future, extremely fast mobile connections through 5G which are being trialled around the world. Once you are using your laptop in this way, you’ll probably find yourself in work mode and, just like when you are in the office, you’ll stop considering the amount of data you are consuming. Therefore, it is advisable only to connect when you need to and avoid applications, like Dropbox, from continually syncing in the background. This can eat huge amounts of data very quickly!


How to keep tabs on the data you use


The amount of data you use can be easily monitored and controlled in your smart phone’s settings as follows:


Apple devices • Enter your settings and then mobile data • You should see list of your apps with usage underneath each. At the bottom you will find usage for “system services” such as Siri, push notifications, software updates, backup and Apple ID services


• You can “turn off” individual apps for when you are using mobile data by clicking on the switch next to each


• Go to the Apple Store for data monitoring apps such as Data Usage, DataMan Pro and My Data Manager.


Android devices • Go to settings and then data usage • Look at the graph that shows your data usage over a set period


• Adjust the coloured bars to set a warning when you are approaching a level you do not want to exceed


• Set a limit to the amount of data you use • Look further down the screen to find your apps and the amount of data they use


• Go to Google Play where you can find apps such as Data Monitor: Simple Net-Meter; GlassWire Data Usage Monitor and My Data Manager for even more control of the data you are using


Windows 10 mobiles


Windows 10 enables you to set data limit by • Tap settings/network & wireless/data usage and tap set limit


• The displayed graphic gives an overview of data usage from the last 30 days split between SIM and Wi-Fi


• Click on “set limit” to set data limit Infrastructure


Public Wi-Fi, despite the security risks, has become the norm on public transport, in restaurants and bars and, even though it is often slow, it has led to an overall decrease in end-user paid-for data usage. The UK is lagging behind with its telecoms infrastructure. Last


year, it was only 54th in the world for 4G coverage, according a report from the UK’s National Infrastructure Commission, and people cannot access data fast enough for their needs. As a country, we are not keeping up with the fast-paced speed with which technology is changing. The next few years should see a move towards faster


connections. 5G promises to deliver data as much as 60 times faster than a 4G wireless connection. Whether this will drive data usage in the future is still uncertain because the right infrastructure needs to be in place for it to be truly effective. Considering there are still many problems with our 4G connection, it is unlikely that 5G will drive data speeds up any time soon. Fifty-six MPs sent a joint letter to digital secretary Matthew Hancock in May 2018 asking him to challenge the current speed and ambition of 4G coverage rollout in rural areas. Many rural (and some inner city) areas as mobile ‘not-spots’ – something that has to change if the economy is going to benefit from a digital future, and if UK businesses are to continue to compete on an international stage. In the longer-term as 5G becomes the accepted norm


and mobile connections (hopefully) become more consistent throughout the country, data usage and the need to buy more data will only increase. Just as smart meters in our homes increasingly help us


control the amount of energy we consumer, we will all need to ensure that none of us waste data.
