I get maybe a few a month…
There are times where there are spikes in activity on these, where may get a few a week.
Those are just drive by robo dialing…and they move on pretty quickly.
I had recently tried activating a spare phone on Tello, to try, and it came with a new number.
That, number must have been reused quick, as it got many robo calls from some local school district every day about some childs attendance. Also got a couple spam calls every week, only had it active 1 month.
No where near as bad as the phone i got to test from Qlink Qwirless under the government Lifeline Wireless program for free cell service for qualified persons like my mother. That thing, the second i activate the line had 12 VM’s all spam of various sorts and gets several calls a day.
and FYI, i checked, both the numbers of the 2 mentioned phones i was testing out, the number has been on the Do Not Call list since mid 2000’s.
