oi amor quando voce vem a bilboa mi falar a data ? certa para eu buscar um hotel para voce. ficar e sim voce cuizer mi liga neste munero de telefone ok .
Hallo Liebling, kannst du mir das Datum sagen, wann du nach Bilboa kommst, damit ich ein Hotel für dich suchen kann. Wenn du Zeit findest, ruf' mich doch unter dieser Telefonnummer an, ok.
Maybe the idea in portuguese expressed by "se você quiser, me liga..." would be that it's possible to contact the person through that number. Would "Du kannst mich unter dieser Telefonnummer anrufen" sound ok?
Though in the source there's no "?" in the end (after "ok", I think that was the intention.
