About Truphone
Truphone has been championing digital mobility and customer choice for decades, allowing things, businesses and people to communicate freely. We believe that the better the world communicates, the better the world.
Every day, Truphone engineers better connections between things, people and business. We have invested in state of the art SIM software, intuitive management platforms and a powerful global network to make this a reality.
Our History
Truphone was founded in 2006 on a farm in Kent with a mission to improve connectivity to mobile services where current cellular providers could not reach.
Since then, Truphone has invested in becoming the world's first truly global network through its own network infrastructure (points of presence include: London, New York, Amsterdam, Sydney, California and Hong Kong) and partnerships with other operators. Its patented technology now serves over 3,500 multinational enterprises in 196 countries.
“At Truphone, we’re renowned for our technological breakthroughs – and for our game-changing products that help businesses and individuals get better connected worldwide.”
Patented SIM technology.
Our international multi-identity SIM seamlessly switches to operate like a local SIM – with local data speeds, call quality and costs. Uniquely with us, you have multiple international numbers on a single SIM. What's more, our SIM integrates with eSIM.
