Welcome to Vodafone Community
It is a number of years ago since the V4 Sure Signal was discussed and having just bought the clearly relatively hopeless V3 which does not work with the iPhone 5 no matter what I do with it, I was wondering if a V4 was now on the cards ..... ?
I'm sorry to see your having problems connecting your iPhone to your current Sure Signal, have you followed the steps in our troubleshooting guide? If the information in the initial steps don't help, please follow the issue not listed link and we'll be happy to take a look.
It looks like the brand new sure signal has just died.
This is hopelessly unsatisfactory.
Where I live just outside Bristol city centre has no signal .... which is a pain .... but for the "reserve" system to be unworkable makes little sense to me.
