For this such obvious behaviour of bergoglio there can be only one explanation.
He got that cellphone from someone who installed him on that seat.
Does anyone thinks Our Lord needs the cellphone to reach anyone?
Of course not!
Furthermore, someone who gave him that phone is probably the only one who have that number and also the only one who call him.
And he must keep that phone al the time, and he also must take the calls every time they call him.
And why do they call him on that moment exactly? Because they will make fun of him and they send a clear message to everyone about who are his bosses.

La dépendance au téléphone portable se soigne, Bergoglio, en foutant ton appareil à la poubelle. Tu es le premier pape (si tant est que tu sois vraiment pape...) en deux mille ans esclave d'un bidule superfétatoire.

La ordinariez de Bergoglio también la mostró al interrumpir telefónicamente una misa oficiada por Prefecto Muller, cuando le pidió que la abandonara para atenderlo. Jesucristo y los fieles pueden esperar según Bergoglio, ante una llamada suya.
