We estimate that we’ll be switching off a 3G mast here on [dateplaceholder]. So, there may be reduced or no 3G coverage in this area from then onwards. Please check back regularly. Find out more about our 3G switch off.
Please note: The coverage checker map may not accurately reflect switch off in real time. There may be a delay of up to 30 days.
Our coverage map meets Ofcom's High Confidence standard for 5G coverage. However, although these coverage results are accurate, the information is only a guide and doesn't guarantee service availability in a particular location. Coverage may vary depending on your device and whether you're indoors. We are continuously improving our network to ensure our 5G service reaches even more customers.
What's the difference between 4G, and 5G? Well, they're the 4th and 5th generations of mobile network. The main difference between them is the speeds they can reach, with each generation hitting faster speeds as they go along. This affects how smooth your online experience is.
Our 4G and 5G Home Broadband hubs can get you online as soon as tomorrow, all with unlimited data. No landline. No engineer. No waiting. It's broadband, but better.

Location’s usually the main thing that affects coverage – if you’re far away from a mast, your signal will be weaker.
But coverage can also be affected by things like trees, being in a basement or underground, travelling, and even your phone itself. Getting higher up, opening windows, and upgrading your phone can all help improve your signal.

Unfortunately, no network can tell you how strong your signal will be indoors. That's because the signal strength needed to pass through walls and windows varies from building to building.
Your SIM card, phone settings, a low battery, and running older software can all affect the signal. If your account is on hold, that will also prevent use of the network.
The closer you are to a mast, the stronger your signal. It can also be affected by geographical things, like hills, valleys, forests, etc.
Strong winds, flooding, storms, falling trees, etc. can all affect phone masts.
Cranes or scaffolding, for example, can obstruct the signal.
When we're carrying out planned or unplanned maintenance, your signal will probably be affected.
We’ve now phased out our 3G network across most of the UK.
You may have reduced 3G coverage or no 3G coverage at all. If you’re using a device compatible with 4G Calling, you’ll be able to access to our 4G network where it’s available.
If you normally have a signal but have recently lost it, there could be an outage or an issue with your device or account. Here are a few things you can try to get your signal back up-and-running again.
To use our 4G or 5G network, your device must be 4G ready and support 4G Calling. You can check this and find steps for switching on 4G Calling on our device support page.
If you’re using a 3G only device, you won’t be able to use our services. And if you’re using a 4G device without 4G Calling, you’ll be able to text and use data, but calls won’t work.
The following troubleshooting steps may help to improve signal:
If you haven’t already, check the current service in your area for any outages that may be affecting you.
Sometimes, an issue with a bill or a failed Top-up can stop access to our network. Log in to My3 or the Three app to check for any issues.
You can call and text over Wi-Fi with Wi-Fi Calling. It’s pre-installed on some phones and is compatible with iOS and Android devices.
If these tips haven’t worked and you still need help with your signal, please get in touch with us.
Ongoing signal problems can be frustrating. Here are some troubleshooting steps that may help:
To use our 4G or 5G network, your device must be 4G or 5G ready. And if you use your device for calls, it must support 4G Calling.
You can check this and find steps for switching on 4G Calling on our device support page.
If it only happens in one area, this may be because it’s an area with weaker signal, or there’s an outage or planned works affecting the coverage in that area.
You can check the network status and expected signal strength in any area using our coverage checker.
If the problem happens everywhere, there may be a problem with your device. The following troubleshooting steps may help:
Sometimes, an issue with a bill or a failed Top-up can stop access to our network. Log in to My3 or the Three app to check for any issues.
If you’re in an area of weak or no signal and have access to Wi-Fi, Wi-Fi Calling can be a perfect solution. It lets you make and receive calls and send and receive texts over Wi-Fi. It’s pre-installed on some phones and is compatible with iOS and Android devices.
If none of these troubleshooting steps have worked and you still need some help, please get in touch with us.
Having trouble connecting to the internet? Or getting slow speeds? This may be due to high levels of traffic at peak times. Try the following steps to get back online:
We’ve now phased out our 3G network across most of the UK. So, to keep using our 4G and 5G network, your device must be 4G or 5G ready. And if you use your device for calls, it must support 4G Calling.
If you’re using a 3G only device, you won’t be able to use our services. And if you’re using a 4G device without 4G Calling, you’ll be able to text and use data, but calls won’t work.
The following troubleshooting steps may help with internet connection and speed problems:
Check the Access Point Names (APN) in your settings and try resetting your network settings. Remember, this will restore all network settings – including Wi-Fi networks and passwords, cellular settings, APNs, and VPNs – to factory settings.
For more help, go to device support, pick your device then go to How to guides. You can find the APN details by going to Check your internet settings. And steps on how to reset your network by going to Connectivity or using the search bar.
Whether you’re on our 4G or 5G network, you should have access to the internet. Check the expected signal strength in any area using our coverage checker.
While we try to sort out the issue, it may be helpful to connect to Wi-Fi whenever you can.
If you’ve tried these steps and are still having internet trouble, please get in touch with us.
