How to cheat the tariff time?

Question

Programming

I connect to the Internet through a mobile (android-huawei) phone. I have a tele2 operator, the tariff from 00:00 to 9:00 is free. There are no connection problems. How to set the time at noon, for example, between 00:00 and 9:00 so that the Internet is free all the time?

Answer 1

Hack the operator's server, in your case tele2 :)

Answer 2

@c_pro_lang so

Answer 3

Billing occurs on the provider's server side, according to its clock.
Manipulating the local device does not make sense.
