Typisk fejl:
Learners sometimes say *"open my account"* when they mean *"activate my account"*. "Open" is used when the bank first creates the account; "activate" is used when you make a card, phone, or service start working. Another mistake is using a verb form *"I will activation my card"*; the correct verb is *"activate"*.
