I need help implementig this: https://en.wikipedia.org/wiki/Cell_Broadcast
As probably you know, not every phone has this option and i need someone that knows how we can implement it, mostly on Xiaomi and One Plus phones.
This is a job offer, if someone knows how to do this, i will pay for your time and your work.
Thanks in advance.
