How do you know that account is activated in bank?

One way of telling if your bank account has been activated is when you receive your credit card/ATM card. When you go to purchase an item with your bank card, the machine that is processing your order may deny your purchase or accept it. If it denies it, that means your account has not been activated yet. If it accepts it, that means your account is activated.

You can also go on-line and open an on-line account with your bank.

Call your back to see if your account has been activated.

The recommended method you should use is the initial method listed above.
