Truphone has launched a beta of its mobile internet telephony service, Truphone Anywhere, for BlackBerry smartphones.

The company says Truphone Anywhere brings simple, easy and cheap international calling to up to 40 million BlackBerry users across the world.

Truphone Anywhere works in 33 countries worldwide alongside domestic service providers, but reduces international call costs to £0.03/$0.06 per minute.

The service appears easy to use - instead of requiring the user to remember what to do, Truphone Anywhere asks whether he/she wants to make a Truphone call whenever an international number is dialled.

"There's no GSM business tariff that gets close to the prices we can offer BlackBerry users with Truphone for international calling," said Geraldine Wilson, new CEO of Truphone.
