Get better coverage at home

Some people struggle to get a good network signal at home – things like thick walls, basements and certain types of glass can reduce your signal. Signal box is a device that uses your home broadband connection to give you great reception around the house.

The Signal Box plugs into your broadband router and creates a link to the EE network to provide indoor coverage. It's really simple to set up, and once it's up and running your phone will automatically connect to make sure you can make and receive calls. Using your Signal Box won't cost you any extra – calls and texts are charged at your usual plan rates.

How does it work?

Signal Box works by providing 3G coverage with a range of about 15 metres, so anyone with access can make a call or send a text just as normal. Any Orange, T-Mobile or EE plan holders with a 3G or 4G handset can use the same box.

Once set up, you can use Signal Box to make and receive calls and texts. For data we recommend you connect to your home WiFi because it saves on your monthly data allowance and is generally faster.

What you need to get going

You'll need a minimum fixed broadband download speed of 512kbps and an upload speed of 256kbps. You can check your speed at www.speedtest.net. It’ll work no matter which Broadband provider you use.

You'll also need:

  • a spare Ethernet port in your router
  • a spare power supply near your router
  • a 3G compatible phone on Orange, T-Mobile or EE.

Set up and use

A guide to help you set up and activate your Signal Box is included inside the box when it arrives.

Location of the Signal Box

To get the best performance from your Signal Box, you need to make sure it's at least 60cm away from your router. Don't wall mount it. If you can, keep it off the floor at table height to achieve maximum range.


To activate your Signal Box you'll need to call Customer Services with the IMEI number, which is printed on the packaging and the Signal box itself, along with the post code where the Signal Box will be used.

  • If you're on an Orange plan call 0800 079 0275
  • If you're on a T-Mobile plan call 0800 956 3146
  • If you're on an EE plan call 0800 956 6141

Make sure you have your Signal Box handy when you call, because we'll need a number that's printed on it. The green light will flash quickly while it's activating and turn solid green when it's ready to use. This usually takes no more than one hour to happen.

Using Signal Box

Once activated, your number will automatically work. Just make calls and send texts as normal. Other Orange, T-Mobile and EE users will also be able to use the signal too if they are in range. 

Whenever you're on a call connected through your box, the green light will flash slowly and you'll hear a beep at the start of the call.

Up to four people can connect to your Signal Box at any one time. However, if you have a slower broadband connection this could be limited to one or two people connecting at the same time.

As Signal Box uses broadband to create a signal, it will use some of your of your home broadband allowance. To give you a guide – a 20 minute call will use around 9MB. For an average household we predict the Signal Box will use around 500MB a month, but it depends how many calls you make and messages you send. 

When you use Signal Box, we recommend you connect to your home WiFi because it saves on your monthly data allowance and is generally faster.

If you stray out of the range of the Signal Box whilst you’re on a call, your call may drop.  If there is an EE signal available when this happens your call will continue uninterrupted. However if your phone can’t connect to the EE network, your call will drop.

You need to have a handset that works with 3G for Signal Box to work. Older 2G handsets cannot use Signal Box as it relies on a 3G signal.

Emergency calls

It's important to remember that the Signal Box should not be relied upon for access to emergency services such as 999. If your broadband stops working, or you have a power cut, the Signal Box will not work.

WiFi Calling

If you get patchy signal at home, or no signal at all, you can now call and text through your WiFi.  And for small business customers, you’ll be able to do the same at the office, a client site or even a café too.

It’s called WiFi Calling. And it’s only on EE. You don’t even need an app – just connect to WiFi and use your phone as normal. Get more information on WiFi Calling.
