AT&T is the only carrier offering an integrated fiber gateway with automatic 5G wireless failover at no additional charge (Business Fiber 1 Gbps+ plans). Wi-Fi 6E gateway switches seamlessly to the AT&T 5G network during fiber outages — competitors charge separately for backup connectivity or don't offer it.

Dedicated Internet's 100% uptime SLA means even one second of downtime qualifies for a credit. Industry's strongest SLA package: under 37ms latency, under 1ms jitter, 99.95% data delivery, automatic monitoring, and priority restoration. Dynamic Defense blocks 96% of cyberattacks from within the backbone at no extra cost.

Plus up to $750 ETF buyout for switching from a competing provider.
