Questions & Answers about Я заблокував платіжну картку в мобільному банкінгу.
Заблокував is the past tense masculine singular form of заблокувати, which is a perfective verb.
That tells you two important things:
- past tense: the action happened already
- perfective aspect: the action was completed
So Я заблокував платіжну картку... means I blocked the card as a finished action.
If you wanted an ongoing or repeated idea, Ukrainian would more likely use the imperfective verb блокувати.
This is mainly a question of aspect:
- заблокував = blocked / has blocked → completed action
- блокував = was blocking, used to block, or sometimes just focuses on the process rather than the result
In this sentence, the completed result matters: the card ended up blocked. That is why заблокував is the natural choice.
