Yes, I got it to work with my Pre-Paid Verizon plan.
I bought this 12-1-2019 to use with my Verizon Pre-Paid plan.
I got it to work very easily, but not with the help of the Verizon owned Verizon store I went to (they tried it and couldn't get it to work, and said it wasn't compatible).
I was going to return the phone to Best Buy, but I decided to put the SIM card in the slot designed for a micro SD card using the adapter that BLU includes with the phone.
When I put the SIM card in the slot designed for a micro SD card using the adapter, the phone immediately gave me a message that it was connected to the Verizon Network, and the phone work fine. I can make and receive texts and calls and use the internet of course.
So in order for the BLU - Vivo XI+ with 64GB Memory Cell Phone (Unlocked) to work on the Verison Network you have to put the SIM card in the Micro SD slot using the SIM card adapter provided with the phone. So the down side is you can't add a SD card in this instance.
