What is National Roaming?
National roaming is both a technology and a regulatory framework that allows mobile phones and other connected devices to access multiple mobile networks within a country. It creates redundancy and strengthens resilience in crises where individual operators’ networks may be down or overloaded.
How does National Roaming work?
- Automatic network switching: If one operator’s network fails, devices can automatically connect to another available operator.
- Prioritization of critical services: Emergency services, municipalities, and other vital functions can be given priority in the network.
- Improved coverage during disruptions: Ensures continued communication even during major outages or attacks on telecommunications infrastructure.
Why is National Roaming relevant?
- Supports communication for emergency services, police, and healthcare during crises.
- Reduces vulnerabilities in mobile networks through increased redundancy.
- Ensures that civilians and authorities can remain connected even in extreme situations.
National roaming is one of several tools for building a robust and resilient digital infrastructure. When used effectively, it contributes to greater security, availability, and crisis preparedness across society.
