Construction sites rarely need unlimited data usage; in fact, the vast majority of our customers use less than 40Gb per month.
The key to keeping data charges under control is usage reporting. A good control panel should give you access to your data usage, even predicting the amount of data you are likely to use.
Our construction site broadband package gives you access to a portal with statistics for each site. Email alerts are sent when your package usage reaches 25%, 50%, 75%, 90%, and if you have gone over quota. Additionally, if statistics show that you are likely to exceed your monthly allowance, you will be warned of this.
Our conclusion is that you don’t really need unlimited 4G data: you just need to be able to control your usage.
