Hello, can you just use your postal savings card to transfer money to the balance and send text messages on your mobile phone?

If postal savings card has opened the SMS service, as long as there is business, you will receive SMS. If it is not turned on, you may not be able to receive text messages. By the way, are you talking about the balance of Alipay? In fact, the SMS notification of the bill is that no matter who the payee is, the transfer to Alipay will be regarded as an expense.
