Yup. Most of the 2nd line numbers monitor this activity because it is the same activity that sets off alarms to the provider that a scammer would show. VPN, lots of out going calls in a short period of time, etc. Which, if you think about it, it kind of is in that description.
so even if you pay for the premium package, and it’s described as “unlimited” they still shut you down; at least on the temporary. It’s no where in any of their agreements but from what I can tell, they limit you to like 10 calls in an about 15 mins, I dunno for sure tho.
The best one I found was Burner app. But a PCH scammer reported me for “offensive activity “ and got me banned. pinger is ok, but their voice quality is shit.
I used to with Textnow but now I spread my calls out across the apps
