Hahahah, this seems impossible, otherwise im fked.
Everyone is fucked if this actually happens.
Even government officials don't have PTA certified phones, so PTA should stop starting these stupid campaigns and focus on addressing complaints against all the 3rd class ISPs we have in this country.
This kind of crap is a dumb and easy way to get more money out of us, nobody understands why, they'll just throw money at them to ensure their phones work fine.
However, I wouldn't be too worried, the mobile networks here might throw a fit because they'll have to gather IMEIs for every single non registered phone and hand them over to PTA, that will
1) Take forever
2) Possibly not even happen since the networks might not agree to it
So I guess there's nothing to worry about.
