Translation:Your telephone is very big. You need a mobile phone.
I've had the same iPhone 5 for years so I don't have that problem

a poŝtelefonon is definitely a pocket telephone, especially when compared to a very big phone. a cell phone or mobile phone is characteristically different from a landline phone because of the way it transmits and receives signals, has nothing to do with size.
