As soon as I get to the end of the road towards the town centre my signal completely drops. 

My partner is also on ID and has the same issue, so I know it isn't my phone that's the issue. 

I've also got coverage outside of the town centre so the problem is definitely localised. 

Coverage has never been great in town, the old buildings don't help but this is everywhere both indoor and outdoor. It just drops dead. 

Does anyone have the same issue?
