By owning the technical infrastructure that underpins the service, unlike other roaming companies, CallBlue GSM has complete control over call costs, quality, security and billing. Callers will always receive the best signal from their handsets because all calls are switched directly from the home network.

By simply inserting a CallBlue GSM SIM card, customers have instant access to some of the lowest international call costs in over 115 countries. Using call-forwarding, users can ensure that calls to their normal UK mobile number can be answered on CallBlue GSM when roaming and in turn not incur any roaming charges. As a result, they can avoid the inconvenience of giving out a new number.

"Transparency is key," says Les Green, Chairman of CallBlue GSM. "All CallBlue GSM SIM cards are pre-pay, and because we own the network, we can control the rates and the billing. To ensure price transparency and security, an SMS message is sent after each call, informing the caller of the costs, with no nasty surprises. Customers can also top up and check their balance either online or from their phone."

Jay Shah, CEO and Founder of CallBlue GSM adds: "Launching CallBlue GSM is a significant milestone for me since I have been working on this project for over two years. We are committed to providing the best product, experience and service in global roaming for our customers. This service is a significant upgrade from other roaming packages currently on the market."
