Somebody [or company] sofd my 2FA code phone

When wife died ages ago, I kept her old flip phone. It was for her emergency use, and she never used it once. I have never made or received a call on that number and use it ONLY to get 2FA text codes from various financials.

Yet I get five or more text ads to that phone…every…single…day.

And it’s ongoing with new ads all the time. I suspect I’ll never find the culprit or find a way to stop it, Grrrrrrrr
