SiRRAN Roam-In

Worldwide Connectivity From A Private Mobile Network

All the benefits of a private network with the ability to use any SIM on 2G and 3G and receive inbound calls and SMS automatically to your mobile phone:


“I just want MY mobile phone to work normally”

~ was the direction we received from a senior military officer back in 2009.

This was the catalyst SiRRAN needed to develop Roam-In and remove the barriers that make standalone or bubble networks difficult to manage and negate the clumsy user experience. It became evident that to provide a truly seamless solution for users within a private network whilst still maintaining security with “whitelists” and “blacklists” was the only way forward for 2G/3G and LTE private networks.

It is not feasible to expect users to change SIMs or handsets, lose inbound voice/SMS and use clumsy call-forwarding to overcome the limitations of a non-integrated bubble network. This is why SiRRAN’s Roam-In service is seen as the market-leading technology within the 2G/3G/LTE soft core space.
