I have used Signal but that was many years ago.
That's not what I meant. I meant if the provider gives me the number you use for signal your account will be disabled as I am now e.g. +491710000000 and register with signal. So I won't get your contacts but your account is gone and you need to register with another number and tell this new number to your contacts out of band. So you lose your account .
