Sounds much too early (though I don't know where you would look to find this spelt out for customers - I suppose 90 days is a "concession", given one is still very much in contract. Actually leaving would incur termination fees unless in the final month, and that is made clear in the Ts&Cs).
I think "Is My Bill Fair" needs to be a bit more careful with their advice too - did it come with any caveats about checking contracts etc, @Murphy57?
