Llamando a Estados Unidos (desde Colombia) no es complejo y el proceso es fácil, aunque es largo en tiempo. Sin embargo, funcionó.

For some reason phone activation does not work in my country (Guatemala), I'm having to pay in getcid.xyz to get the installation ID, other than that the product works without any problems.

Working great
Thank you

Having to pay getcid for activation every time, because phone activation no longer works, but after that everything is good.

Bought this for use in Australia. The phone numbers don't work. The MS phone line sends you to a MS webpage which is of no use.
Change your region to UK and use Skype to call and activate the product.
