When it's all on the line, CriticalLinc delivers.

Emergencies don't hit when it's convenient. They hit when you least expect them. We're keeping you ahead of the curve with our new CriticalLinc LTE network. CriticalLinc will work for you - delivering highly reliable, highly secure LTE service. Whether you're fighting wildfires, protecting the community or getting the power back on - CriticalLinc delivers mission critical service that goes beyond reliable.

Redundant

We've built redundant network data centers in Birmingham and Atlanta with backup power systems in each location.

Reliable

Most cell sites have an emergency generator or backup fuel cell to keep the power running for days during an outage.

Secure

We secured the CriticalLinc network in lockstep with Southern Company's multilayer, 24/7 IT security systems.
