POTS replacement pricing has stabilized in 2026 but is still poorly understood. Most buildings are paying $75–$1,500 per copper line per month under "special construction" pricing — the question is what the replacement should cost, not whether to replace.
The four real cost components
- Hardware — the LTE-based POTS replacement device with battery backup. One-time cost or bundled into the monthly fee.
- Monthly service — the cellular data plan, supervision, dual-SIM failover and firmware updates.
- Installation — usually 15–30 minutes per line by a local low-voltage tech. Many buildings self-install.
- Ongoing support — monitoring, RMA, warranty, U.S.-based help desk.
Typical 2026 pricing per line
- Bundled (no hardware fee, single monthly invoice): $30–$55 / month per line, all-in.
- Hardware upfront + lower monthly: $150–$300 device + $20–$35 / month.
- Special construction copper (what you're replacing): $200–$1,500 / month per line.
For a typical 10-line building paying $400/month in "special construction" copper fees, the payback on POTS replacement is usually under 60 days.
Hidden costs to ask about
- Activation / provisioning fees per line
- Truck-roll fees if self-install is not supported
- Per-incident support fees
- Battery replacement (every 3–5 years)
- Early termination if you switch providers
