Welcome to Vodafone Community
I have just upgraded my phone to a Samsung S7. This involved changing the SIM. I kept the same number.
Now my phone will not connect to the Sure Signal. I get "Not registered on network".
I've recently created a new account and linked my SureSignal to it and added the phone from new. I also received a text saying this phone can use my suresignal.
The phone works fine when I'm in areas with reception ie not a problem with the SIM.
Other phones can work with the SureSignal.
I've set the phone to work only at 3G since that was mentioned in some places - problem was the same.
My phone number is [Removed]
The serial number of the SureSignal is 42150979054

Once you remove the number, please allow 24 hours to pass before adding it back on.
Your phone should then be working and connected to your device - please let us know how you get on 🙂
