Burner apps. Providers know you're using them?
I use a burner app. If you're familiar with these apps they assign you a telephone number which you can then use to text or make / receive calls through your mobile phone. For me, it is the safest way to go as I'd prefer not to own an additional phone.
On several occasions I've had providers refuse to communicate with me because they objected to the use of this number. I understand why a provider may feel their safety is at risk if they don't know, and can't trace, the monger.
So here are my questions:
1. How do they know I'm using a burner app?
2. Are there any apps that can "get around" this problem?
Thank you.
