What Happens When You Switch from Onestream
For many UK households, Onestream has been a reliable choice for broadband and landline services. Its packages have long combined internet connectivity with traditional copper-based phone lines — the standard setup for years. But as the UK approaches the 2027 copper switch-off, the way we connect our landlines is changing for good. This nationwide shift marks the end of the old copper telephone network and the beginning of a digital voice future.
Understandably, many Onestream customers are concerned. When you switch provider or upgrade your broadband, will your landline still work? Can you keep your landline when switching from onestream? These are common worries, especially for people who depend on their home phone for everyday communication, security systems, or emergency calls.
The good news is that keeping your landline doesn’t mean holding on to old technology. With digital landline and VoIP (Voice over Internet Protocol) solutions, your home phone can continue to function — but through your broadband connection instead of copper wiring. This upgrade ensures clearer call quality, greater reliability, and compatibility with the UK’s all-digital future.
That’s where Plexatalk comes in. Designed as a future-proof digital voice service, Plexatalk allows former Onestream users to keep their landline number, make and receive calls as normal, and stay connected even after the copper switch-off. It’s a simple, seamless way to move forward without giving up the traditional features you rely on.
Why People Still Want to Keep Their Landline
Even in a world dominated by smartphones and messaging apps, many people still see real value in having a landline at home. For some, it’s more than just a phone — it’s part of their identity. It’s the number they’ve had for years, the one family and friends recognise instantly. For others, it represents stability and reliability — a direct line that works even when mobile networks drop out or battery levels run low.
When customers switch from Onestream, one of the biggest concerns is whether they’ll lose that connection. It’s not just a phone number; it’s a point of contact for doctors, banks, schools, and essential services. For older users in particular, the landline offers comfort and familiarity — an easy-to-use, always-available way to stay in touch.
Home-based workers and small businesses also rely heavily on having a dependable landline. It provides a professional contact point, ensures clear call quality, and avoids the patchiness that mobile reception can bring. The thought of losing it during a broadband change can be stressful, especially if you’ve had the same number for years.
Fortunately, keeping your landline when switching from Onestream doesn’t mean holding onto outdated copper connections. With digital voice technology and VoIP solutions like Plexatalk, you can keep your landline when switching from Onestream while upgrading to a more modern, reliable system. It’s the perfect balance between tradition and innovation — keeping what matters most while moving confidently into the UK’s digital future.
What Happens to Your Landline When You Leave Onestream
When you leave Onestream, it’s important to understand what happens behind the scenes with your landline. Onestream’s phone service now uses Digital Voice, which runs over its full fibre (FTTP) broadband network — not the old copper telephone lines. Your landline is tied directly to your broadband account, meaning your Digital Voice service only works while you remain an Onestream customer. Once your broadband is cancelled, the Digital Voice line is automatically disconnected, and your number can be lost unless you take steps to move it first.
Many customers are caught off guard by this. They assume their landline number will stay active when they change broadband providers, but that’s not the case. Unless you arrange to port your number to another digital voice or VoIP provider before your Onestream account closes, your landline number may be permanently deleted — and once it’s gone, it can’t be recovered.
That’s why careful planning is essential if you’re thinking about switching broadband. To switch from Onestream and keep digital voice, you’ll need to transfer your number to a new, independent VoIP provider before cancelling your Onestream service. This ensures continuity and protects your contact details from being lost.
With a provider like Plexatalk, the process is quick and seamless. You can port your number easily, keep using your home phone, and enjoy all the benefits of a flexible digital voice service — clearer calls, lower costs, and complete freedom to use any broadband provider — without losing the landline you depend on.
Why Onestream Landlines Don’t Work on FTTP / Full Fibre
Onestream is now a full fibre (FTTP) broadband provider, meaning its connections run entirely over fibre optic cables instead of the old copper phone network. This technology offers faster speeds, lower latency, and far greater reliability — but it also changes how landline phone services work.
Traditional landlines relied on copper wires carrying analogue signals between your home and the local exchange. With FTTP, there’s no copper involved and no way to transmit analogue voice — fibre is purely digital. That means there’s no plug-in wall socket for a standard phone anymore. Instead, calls must be delivered as digital voice (also known as VoIP, or Voice over Internet Protocol), using your broadband connection to carry conversations.
To manage this shift, Onestream includes Digital Voice with its broadband, allowing customers to keep using a home phone by connecting it to their router or an adaptor. It’s a modern, fully digital replacement for the old copper-based landline.
However, many other FTTP providers — particularly smaller alternative networks like Trooli, Cuckoo, and others — don’t include any VoIP or digital landline option. If you switch from Onestream to one of these broadband services, your Onestream Digital Voice line will be disconnected, and your number could be lost unless you port it elsewhere first.
That’s where Plexatalk comes in. Our digital voice service works with any fibre broadband connection, letting you switch from Onestream and keep digital voice without interruption. You can retain your existing number, use your preferred handset, and stay connected — no matter which full fibre provider you choose next.
What Is VoIP and Why It’s the Best Alternative
As the UK moves away from traditional copper phone lines, the future of home calling is something called VoIP — short for Voice over Internet Protocol. You might also hear it referred to as digital voice. In simple terms, it’s a modern way to make and receive calls using your broadband connection instead of the old analogue copper network.
Here’s how it works: when you make a call using VoIP, your voice is converted into tiny data packets that travel securely over the internet to the person you’re calling. The technology is fast, reliable, and delivers crystal-clear sound quality. All you need is a broadband connection, a compatible phone, and a VoIP service provider.
The benefits are immediate. You can keep your existing number, enjoy lower call costs, and connect your phone in flexible ways — through a router, an adapter, or even an app on your mobile or laptop. Because calls run entirely over broadband, you’re no longer tied to a specific physical location or old wiring.
While many broadband companies (including Onestream) offer their own digital voice service, these are usually locked to their routers and networks. That means if you change broadband providers, you may lose access to that service — and possibly your phone number too.
A dedicated VoIP provider like Plexatalk gives you far more freedom. You can keep digital voice after switching from Onestream, use your own equipment, and move your service to any internet connection, anywhere. Plexatalk lets you stay connected independently of your broadband provider — keeping your landline number, enjoying professional call features, and staying ready for the UK’s fully digital future.
