What's Signal Box?

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. It plugs into your broadband router and creates a link to our network to provide indoor coverage.

It works by providing 3G coverage with a range of about 15 metres, so anyone with access can make a call just as normal. 

It’ll work no matter which broadband provider you use. But you'll need a minimum fixed broadband download speed of 512kbps and an upload speed of 256kbps.

You'll also need:

    a spare Ethernet port in your router


    a spare power supply near your router


    a 3G-compatible phone on EE


How to activate your Signal Box

If you're on an EE plan, call us on 0800 956 6141.

You’ll need the IMEI number (it’s on the box) and your postcode.

Using your Signal Box

Once activated, your Signal Box will automatically work. When 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.

As Signal Box uses broadband it will use some of your home broadband allowance. As 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 texts 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 while you’re on a call, your call may drop unless there’s an EE signal available when this happens.

You need to have a phone that works with 3G for Signal Box to work. Older 2G phones cannot use Signal Box.

What do the lights mean?

What do the lights mean?

  1. green light flashing quickly

    your Signal Box has lost its connection with us. Try unplugging it and then reconnecting it again, leaving it for a few hours to rectify itself. If the problem persists, call us on 150 free from your EE phone

  2. red light – single flash

    Signal Box isn't connected properly. Check the cables are plugged in correctly to the router and your Signal Box. If this doesn't work, try changing the Ethernet cable and leave it for a couple of hours to reset before giving us a call

  3. red light – sequence of two flashing lights

    the Signal Box isn’t receiving an internet connection. Check the connection of your home broadband

  4. red light – sequence of three flashing lights

    something else is interfering with the signal. Make sure the Signal Box is at least 60cm away from the router and check it's not too close to other electrical equipment

Changing broadband or router

If you change your home broadband supplier or router, then the Signal Box will stop working and the green light will flash quickly. 

You'll need to call us on 150 to get it reactivated. This is just a security feature to help us prevent fraud.

If you're moving home

If you move home, you may find that you won’t need to use your Signal Box any more, depending on network coverage in your new home. Find out more about 4G Calling and WiFi Calling and see if you have a compatible phone. 

If you find that you still need to use your Signal Box in your new home, call us on 150 to get it reactivated. This is just a security feature to help us prevent fraud.
