Cultural Tip
In most of Latin America "móvil" is the everyday word for a cell phone, while in Spain people often say "teléfono móvil". Percentages are usually spoken as "cien por ciento" rather than "100 %", so you might hear "cargado al cien por ciento". The subjunctive after "asegúrate de que" is a subtle grammar point that shows the speaker’s desire for the condition to be fulfilled.
