Apple Music via Verizon, only one device can stream?

I have Apple Music through my Verizon account and my wife utilizes it as well, same Verizon account, different Apple ID. We recently both tried to steam Apple music at the same time on our phones, but we received the error "your device limit has been reached".

Does this mean with the Verizon bundle, only one device can stream at the same time? If so, what are the other options?

Thanks.
