Aren’t T-Mobile and Sprint merging? Wouldn’t that improve coverage, perhaps for both but at least for T-Mobile? I don’t know when it’s taking effect though.
All depends where.
I am about half a mile West of Woodridge and only ATT works there.
In Woodridge itself there is a bit of Verizon.
Go to Woodbourne and its different again.
So it very much depends where you are in the Catskills
And it keeps changing every year (usually to the better)
