Is it better to cancel the SMS service of ABC or not?

It's better to keep it, because although it costs 24 yuan a year, the money in and out of your account is within 1 minute, and the bank will send you a text message to make you feel at ease. On the other hand, SMS will also tell you the balance of the deposit, and also avoid the trouble of going to the Agricultural Bank of China for inquiry.

You said that your mobile phone didn't receive the text message of funds entering and leaving the Agricultural Bank of China. There may be three reasons: ABC, the mobile company and your mobile phone. I suggest you take your mobile phone to the counter of Agricultural Bank of China to check and verify it first. If there is nothing wrong with the bank, check with the mobile company. Sometimes your mobile phone has turned off the function of accepting public short messages and needs to be reopened in the mobile company.
