O2 Business Essentials

O2 understands that supplying a mobile device to a business is different it than supplying it to a person. Businesses change all of the time and running a business is stressful enough without having to worry about the flexibility of your network. The O2 business essentials packages offer everything that a business could need including convenient and flexible tariffs with all phones having 4G, unlimited calls and texts. It is then left up to the user to decide how much data they will need to use. You can add more phones to the one contract if needs be, which allows you to have up to ten phones under one contract which is massively convenient when it comes to monitoring and paying bills for all of the phones in your company. The monthly bills will come in two payments, one that pays for all your usage, minutes, data etc and one that will pay for the actual devices themselves. Want to pay less each month? Make an upfront payment for your devices. Please call the o2 Business contact number if you would like to know more about how the business tariffs work.
