Unfortunately, I went so long without actually using it that they took my number away (my fault because they did send me a warning but I just forgot about it). Now I'm in the same boat as you as I had switched to a Skype Number after that.
But Google Voice is a decent free option to consider if there's someone in the US who could help you with initial activation. Until Google finally decides to kill it, at least. I'm frankly surprised that Microsoft killed Skype before Google killed Voice.
