Vodafone Sure Signal

Sure signal stopped working after sim card changed


@IanM123 A resync of your device won't help in this situation. 

As you've changed your SIM card, you'll need to remove and re-add the phone number on the device - make sure to leave a 24 hour period between this.

If you need help removing and adding the number, please pop a message to our Live Chat team. 

Let us know how you get on 🙂

I've not been able to remove my number as I am the owner (seems a common issue with other users).  The instructions I've seen on line to overcome this aren't very clear.  

An additional problem has now developed on my device where it doesn't seem to be getting connected to Broadband - the lights keep going through their startup sequence and then cycling back to the beginning again.  I've restarted the router (BT Hub6) and the SureSignal but no improvement.  I'm thinking it's maybe an IP address issue?

@IanM123 I understand how frustrating that must be, please try de-registering the device and then re-registering.

De-registering your Sure Signal stops it working and removes everyone who uses it.

  1. Log into My Vodafone and select your number. Click on Manage services, then click on Sure Signal and choose the device you want to deregister. Then select Deregister Sure Signal
  2. Unplug your Sure Signal

You can then re-register it again, for further instruction how to do this, please see here 

Please let us know how you get on 🙂

I've de-registered and re-registered and swiched my SureSignal device off for two weeks but it's still no longer able to connect to the network (keeps going through the lights startup sequence) so I can't test to see if signal output is working again.  Anything else I can try?

@IanM123 - I can see your Sure Signal has now made contact with the network at 3.18am today.

I hope that it’s working for you now. If it isn’t, please post back the below template with your answers:

Hello Gemma,  My SureSignal is still not connecting unfortunately.


The light sequence is as follows:

Solid top light for a couple of minutes, followed by solid top light and flashing second light for another two or three minutes.  Then both top and second lights go solid and the fourth light starts flashing for a minute or so. The fourth light never goes solid. Then the 2nd and fourth lights go out, leaving the top light solid for about 30 seconds before all 4 lights illuminate one at a time and the above sequence starts all over again.


My speed test results are:

Ping: 16ms

Download: 29.10 Mbps

Upload 18.31 Mbps


My IP address from the link you provided is:


My external address according to my router is

 To me it looks like I'm not connecting to your server but I can't see why.  Can you shed any light?

@IanM123 - Thanks for coming back to us with that information.

The first light sequence you’re getting, indicates your Sure Signal is attempting to register across the internet connection.

Please test your Sure Signal at a different location (using a different internet provider).This will rule out a faulty device.

If it works ok there although not at your address still, please get back to us with the exact coloured lights your getting and if they're stable or flashing.

I've tried the device at my son's address using a different ISP and unfortunately had the same results, i.e. the same light sequence constantly repeating.  I'm guessing that my SureSignal has therefore failed.

@IanM123 Thanks for coming back to us Ian 

It sounds like you need a new Vodafone Sure signal device. 

I've sent you a private message with details on how to get in touch so you can arrange this.
