Business Broadband FAQs

We use 5G broadband to bring you an internet connection, just as we do on your phone. Instead of using fixed fibre technology, it uses 5G mobile technology, so you can use it on the go. 5G Business Broadband gives you superfast speeds online allowing streaming, downloading, and increased capacity for multiple users.

Read our 5G Business Broadband buyer's guide to find out more.

This depends on what devices you’re connecting, and what you’re doing with them. Officially you can connect up to 30 devices to your hub. The more devices you have actively connected and using the internet, the more your speeds will be impacted.

It couldn’t be simpler – insert the SIM card sent with your hub, and plug the hub in. That’s it. We also offer next working day delivery when you order during business hours before 1pm. (Selected postcodes only.)

Try a few different places, and see where you get the best signal strength. Your hub has 3 signal lights on the front of it, and the more lights, the better the signal. Avoid positioning your hub with obstacles between where it sits, and the place you’ll be accessing your broadband. Doors, walls, and even things like fish tanks can affect your connection. We recommend placing it on a few different windowsills to see which direction gives you the strongest signal.

We suggest you do this by setting up Guest Wi-Fi, so you can avoid having to give out your main password. Connect your hub, then log in to get to the configuration page. You’ll find the log in details you need on the base of your new hub. Select Wi-Fi > Guest SSID, and you can set up Guest Wi-Fi from there. Remember that connecting lots of devices at the same time could impact your connection speeds.

Yes. To do this, enable Wi-Fi calling on your business devices. How you do this may differ depending on the device. See how to enable Wi-Fi calling here.

Yes. As long as you’re still within our coverage area, you can plug your hub in and connect just as you did at your previous address. You can check your coverage at your new address with our coverage checker at the top of this page. Performance may vary.

No static IP is available with our 5G Business Broadband. Most customers don't need one, unless (for example) a VPN is used to whitelist specific IPs.

Yes. And when your area becomes 5G enabled, your device will automatically connect you. You can use the coverage checker at the top of this page to check the speeds available in your area. Remember that 4G speeds are not as fast as 5G, and may compare differently to fibre speeds.

No, you can keep your existing service running in parallel for as long as you need to. When you’re ready to leave your existing broadband provider, just contact them to cancel your old contract. If your contract hasn’t expired, they may charge you an exit fee.
