Discord and Eris had an idea to make a portal to the different towns and cities around Equestria so in case of an emergency they could immediately send the guards of Canterlot to that location. So with the help of Twilight, Cadence, Luna and Celestia they tried to attempt it, only Rainbow wanted to see it for herself and accidentally surprised them, causing the first human to be sent to Equestria.
In this Equestria they have phones, tablets, wi-fi, T.V., and videogames.
