Beyond the hacked SMS system thing, you’d be amazed how many places sell your number to data brokers and those data brokers have no issue selling to scammers. I used to get dozens of spam and scam calls a week. I used a service to purge myself from data brokers and switched my phone on all services to an SMS only phone number and I now get at most 1-2 spam calls a week and the scammers stopped entirely. From this point forward unless I absolutely need to talk to you you’re not getting my phone number.
