My name is Postal Savings Bank and Green Cartoon Debit Card. I want to check the balance with my mobile phone for free. Is it okay? How can I check?

However, first of all, you need to go to the window to add the mobile phone on-demand service in person (if you don't go to the window to add it, can't anyone check other people's account balance? )。

Mobile and Unicom users send it to "5 185" and PHS users send it to "95 185" to edit the following information (without quotation marks):

◆ Inquiry on interest rate of savings deposit:

"CKLL": interest rate inquiry of savings deposits, providing customers with the inquiry service of postal savings in deposit interest rate, with an information fee of 0.20 yuan per transaction.

◆ Inquiry of savings business tariff:

"YCZF": savings business tariff inquiry, providing customers with postal savings business tariff inquiry service, and charging 0.30 yuan for each message.

◆ Current account balance inquiry:

"zhye"+"blank"+"current account number": current account balance inquiry, providing customers with postal current account balance inquiry service. You need to add business in the window, and the "current account number" can also be changed to the account alias entered when adding (convenient for your memory and account security). The cost of each message is 0.20 yuan.

◆ Detailed inquiry of current account:

"zhmx"+"Blank"+"Current Account": current account details inquiry, which provides postal current account details inquiry service for customers. You need to add business in the window, and the "current account number" can also be changed to the account alias entered when adding business (convenient for your memory and account security). Each message is charged at 0.50 yuan.
