How to check whether the bank card SMS reminder is turned on?

I didn't watch this on my mobile phone, but on online banking. For example, log on to the ICBC website, enter the account password, and check whether ICBC Messenger has been opened. After opening, there will be a short message prompt to change the account amount. Every bank has a similar SMS service, which is charged, some in 2 yuan/month, some in 3 yuan/month. It can be used for half a year and can be discounted.

Take ICBC as an example. Log in to online banking with your account password. On the top menu bar, line 3, item 6, you can see "ICBC Messenger". Click enter to find item 9, "9 balance change reminder? 2 yuan/Account/Month ",just click" Customize "on the right.
