To block any nuisances that call you on your smartphone to propose contracts,subscriptions,change phone operators............ until yesterday,in my country,it was only possible to block through apps in the smartphone,the numbers of the various call centers. Since yesterday,however,an online opposition register has been established where you can register the phone numbers that cannot be disturbed by telemarketing. In one day as many as 205,000 registrations. https://registrodelleopposizioni.it/ What is the situation like in your country?
The territory state's government and in the MIDSOUTH continental region has a pretty solid NO CALL LIST and going on some years now not a single telemarking call or robo call either of some other sort. Just the usual email notifications that wait the moment for you to lay down to rest. I remember in times past getting routinely plastered with all sorts of those before they fixed it.
