Fairness in everything we do

We aim to be the fairest Internet Telephony service provider

Really Fair Pricing

We offer just two simple, clear and fair call pricing deals.

Traditional metered billing - If you prefer to the second billing choose our fair metered tariff and you just pay for what you use at our competitive rates.
Fair Use Bundle - More and more of our customers are choosing our fair use bundle where we agree a monthly payment based on your expected usage. If your usage stays within +/- 25% of this then you pay the agreed fixed price. If you go 25% above your expected usage then you just pay the extra based on our fair metered tariffs, but if you go 25% below your threshold then we pay you back. Fair is fair after all.
