In terms of United Kingdom phone line providers you may divide the companies into two categories. These will be the haves and have nots. The haves, are giant corporate communications entities such as BT, Talk Talk, and Virgin Media. These companies have the financial clout to offer loss leading incentives that will often lure customers. For example, at the present time Talk Talk is offering customers who sign up for home phone and broadband 12 months free broadband service. Smaller companies such as Hive and Primus that we will label as the have nots, simply do not have the financial wherewithal to match such an offer.
But this does not mean that these companies are not viable and perhaps the best option to make cheap phone calls for you. The larger media conglomerates can afford to give away certain services when they are making a larger overall profit as part of service packaging. When Virgin Media sells a customer package of broadband, home phone line and TV channels that totals over 100 pounds per month, they can afford to offer such features as free phone calls to anyone using a Virgin Media landline to reach a Virgin mobile phone.
