XXSIM, International roam, worldwide calling service

If you’re into being able to make and receive free calls (who isn’t?), then you’ll be happy to know that global SIM card provider XXSIM is looking to expand your way with its own mobile app, complete with integrated VoIP SIP clients.

The app is currently scheduled for release on iPhone, Android, and Windows Phone and will be free to use. We don’t know much about the other features to be included, but we’ve reached out to XXSIM and will update everyone accordingly when we have more information.

XXSIM is a global roaming SIM card-based service provided by Shaston AG that provides coverage in over 137 countries with the recent addition of Ukraine, Thailand, Mexico, and Kuwait. Like a few other global roaming SIM cards, XXSIM provides free incoming calls worldwide with roaming capabilities extending even to countries that do not necessarily appear within its coverage area. Its data services work over 2G and 3G networks.
