"Remember to do something" in English can be translated as "Don't forget to do something." This phrase is often used when someone wants to remind another person of an important task or action that needs to be completed.
If you want to express that you have already done something, you can say "I remember doing something." For example, if you were talking about a trip you took last year, you could say "I remember going on vacation last year."
