If you have no savings (debit card) from Bank of Communications, it is recommended to activate it. I'd better bring my ID card, credit card, debit card and smart phone to the nearest Bank of Communications outlet to open the following services.
Savings (debit card) card and credit card online banking.
Savings card (debit card) mobile banking (free transfer and remittance), SMS reminder of balance change of savings card (debit card) (free at present)
The "automatic repayment" business of binding two cards: in this way, the money can be directly deposited into the savings (debit) card, and the repayment will be automatically made from the savings (debit) card to the credit card on the repayment day.
If the credit card customer service of Bank of Communications calls or sends a text message in the future, it is suggested that you open the "enjoy loan" business (consumption limit *2). If it is not a regular consumption, it is recommended not to open it (because after opening, all your consumption will be automatically calculated in stages and a handling fee will be charged).
All the above services are free. Please consult the bank staff for the specific process.
