There are two types of overdraft alerts – arranged and unarranged.
The arranged overdraft text will tell you when you have started to use the overdraft and help you monitor your arranged overdraft use.
The unarranged overdraft text will tell you when you go overdrawn, for example when a payment leaves your account, and you don't have enough funds to cover it. It will also tell you how much you need to pay into your account and by what time, helping you stay in control of your finances.
