GlobalRoamer

GlobalRoamer is a one-of-its-kind service that certifies and validates pre-paid and post-paid roaming agreements across multiple carriers.

With Keynote SIGOS SIM multiplexing technology, your SIMs are “virtually” transmitted to remote test stations around the world where real voice, SMS, and data calls are performed. This enables you to rapidly test the availability and performance of your roaming services without a single SIM card ever having to be physically shipped to remote test locations.
