Boa tarde! Let’s get nit-picky! What should it be: Falar no telefone OR Falar ao telefone? Sorry… those prepositions have reared their ugly heads!
Tip: em/de/a/por (prepositions) all combine with o(s)/a(s) (the) to make new words: no(s), na(s)/do(s),da(s)/ao(s),à(s)/pelo(s),pela(s). It is correct to not combine the words (em a, por o …) but you’ll find they usually are, so it’s worth getting used to them as they seem to be a common point of confusion
