Direct Answer
DataRemote’s 90X1 POTS IN A BOX® is now certified on all three major U.S. wireless carriers — Verizon, AT&T, and T-Mobile — for operation across both 5G and 4G/LTE networks. Combined with dual-SIM support, this gives businesses carrier flexibility and network redundancy for POTS line replacement, whether deploying in a dense urban core or a remote site with limited single-carrier coverage.
Key takeaways
- The 90X1 is certified on Verizon, AT&T, and T-Mobile — the three major U.S. wireless carriers.
- Certification spans both 5G and 4G/LTE, so the device performs reliably as networks and coverage evolve.
- Dual-SIM support adds carrier-level redundancy on top of network-level failover.
- The 90X1 works with existing analog phones, alarm panels, and other POTS-dependent equipment — no rip-and-replace required.
- Alarm monitoring companies can use the 90X1 as a secure, reliable POTS line replacement for signal transmission.
Unmatched reliability and network compatibility
Being certified by Verizon, AT&T, and T-Mobile to operate across 5G and 4G cellular networks means the 90X1 can reliably run on the most extensive and robust networks in the country. Whether deployed in a bustling urban area or a remote location, that certification gives integrators and end customers confidence that the connection will remain stable and secure — regardless of which carrier has the best coverage at a given site.
Key features and functionality
Cost-effective solution
The 90X1 is designed to replace traditional POTS lines, significantly reducing maintenance and operational costs. It leverages modern cellular and IP networks to deliver voice and data services, making it a cost-efficient alternative to conventional landlines.
Versatile applications
The device is well-suited to a range of settings, including residential, commercial, and industrial deployments. It’s especially useful for alarm monitoring companies, providing a reliable means of transmitting alarm signals without a traditional phone line.
Easy installation
The 90X1 is known for a user-friendly setup process that doesn’t require extensive technical expertise, enabling quick installation. This is particularly valuable for businesses looking to minimize downtime and streamline deployment across multiple sites.
Dual-SIM and network support
