An Overview



CallGSM is a global operator providing cutting edge mobile communication solutions. Headquartered in Bristol, UK. CallGSM was founded for the purpose of developing, and bringing to market, a portfolio of integrated mobile communication products and services based on groundbreaking solutions that would change the economics of international roaming.

Our focus is to meet the needs of three target customer groups - companies engaged in international travel, tourist and international students who migrate across borders regularly, with a value proposition that emphasizes cost savings, cost certainty and ease of use from a known service provider - CallGSM. For the first time ever, thanks to our growing suite of integrated solutions, mobile users will be able to securely and seamlessly roam across borders with the knowledge that CallGSM will take care of all their communication needs. Such integrated services are not yet available anywhere in the mobile industry, and we intend to dominate this segment
