What phone do you have?
My wife very recently acquired a Moto G Power, but this problem happened with her last phone as well, a (I think) Samsung J7. Both purchased from RW.
What plan are you on?

Does your plan include data, or just talk & text?
She initiates a call. The recipient’s phone rings, but she hears no ringing (and so is not sure if the call is going through, though it does). We both use RW, but she says this happens with others, meaning non-RW users. We’ve experimented with both on wifi, her on wifi, other person on data, vice versa, and both on data. Same results. The calls itself seems fine, though she sometimes does not hear the other person speaking at first.
