It works but remember there's the settings in your phone you got to set the billing cycle to the right time or you'll get mixed results.
Also remember depending on you using wifi, data doesn't always "show the same number considering that the phone measures "wifi and data together" and your carrier only measures "phone data" so those numbers will be slightly different.
Hopefully it will get fixed because it's pretty annoying
