When I first switched to XT Last year, I always had excellent coverage, It was always full coverage when I was at home.

For the last few weeks, the coverage has been degraded with the phone either sitting at little to no coverage (1 or 2 bars) or it will cycle between full coverage and no coverage in a matter of seconds cycling like that constantly for the night.
This is causing data sessions not to start among other problems

Ive confirmed this is not a phone issue as a friend's phone also has this problem down the street

Has anyone else noticed this anywhere?
Or is there a good number to call and report this where they will understand what Iam saying?

I'm living in St Kilda, Dunedin
