Your guide to the PSTN switch off in 2025

You've probably already heard about the 2025 PSTN switch off which was announced by Openreach back in 2015, and you may even have already started putting plans in place to help you with the transformation. But, there's a lot to take in and consider.  

At Nasstar, we're on hand to help you understand what PSTN is, why it's being switched off and how it will affect your business. As well as deliver guidance on what you can do to avoid any major disruption to your business operations.  

This page has been created as a resource hub and includes plenty of information about the switch off. As we progress ever closer to the 2025 deadline, it will be continually updated with the latest updates and information. For now, check out our Switch Off Guide, blogs, and FAQ page to understand what the switch off means for you.
