Preparing for the PSTN Switch-Off
What is the PSTN switch-off?
The Public Switched Telephone Network (PSTN) supports conventional landline telephony through analogue signals on copper phone lines. However, as a 20th-century technology, the PSTN is no longer aligned with the demands of modern communication. With more applications relying on mobile-based communication, the PSTN is no longer fit for purpose.
PSTN switch-off dates
The deadline for the PSTN switch-off has been extended from December 2025 to January 2027, providing more time to prepare for the transition. However, delaying action can lead to disruptions and last-minute challenges.

What does this mean for your or your customer’s devices?
The PSTN switch-off will affect devices that rely on traditional landline-based communication, potentially rendering them useless. While VoIP is being adopted as a suitable alternative where voice communication is still required, IoT SIM cards present the perfect alternative for devices that require a data connection, eliminating unnecessary cost, time, and disruption.
With access to all 4 UK mobile networks, Cellhire’s multi-network IoT SIMs can prioritise the strongest signal during network outages, switching networks automatically to prevent connectivity issues.
Transitioning from PSTN to IoT Connectivity
Using cellular IoT connectivity can aid the transition and provide better benefits and control for businesses across the country, while also delivering greater financial opportunities for channel partners.
- Benefits include:
- Widespread coverage
- Scalability
- Security
- Low latency
- Reliability
Where are the opportunities?
VoIP is still a choice for solutions where voice is needed, such as lift comms and door systems. However, there are key opportunities in specialised services by utilising Cellhire’s IoT connectivity instead. Primary services running on ADSL (Asymmetric Digital Subscriber Line) can be replaced with a stronger IoT data connection, improving functionality and performance.
