How can I set the start of the billing month for mobile data limits?

[dave852]

So I'm using a dual SIM P10 Plus and in the options I can set data limits for each SIM however I can't seem to see how I can change when the month runs from. The default is from the 1st of the month which is good for one of my current SIM cards but not the other. Anyone know if I'm missing an option that exists or if this is a flaw in Huawei software?

You have to reset your data usage to zero on rollover day unfortunately
