How do I connect my new SAMSUNG A51 to my existing network extender?

I've had the following network extender for a few years, and it worked well with my old Galaxy S7:

From Verizon's site - my devices:
- Router type = 3G LTE Network Extender
- Broadcast name = Verizon-366A
On the bottom of the network extender:
- Model = SCS-2U01

But my S7 died, and I replaced it with an unlocked Samsung A51:

From Verizon's site - my devices:
- Device model = SAM A51 SM-A515U1 UNL
From the box the phone came in:
- Model = SM-A515UZKNXAA
- Description = SAMSUNG A51 - UNLOCKED

I will try the steps dazzzmien detailed on ‎02-10-2021 03:59 PM in "Phones not under network extender coverage", but does anyone know if anything else needs to be done for an A51?

In addition, I cannot find these documented ways to turn off (or even check) Advanced Calling on my A51, if this is even a factor:
Turn off Advanced Calling
Disable Advanced Calling whenever your Verizon Wireless phone shows 4G LTE coverage to ensure it will properly connect to
the Network Extender. To do this, follow the steps below for your device’s operating system:
•Android™: Go to Settings > Advanced Calling and turn off service*
* In some devices it may be found under Wireless Calling, HD Voice or VoLTE call.

Thanks.

I can understand how important it is to get your device connected to your Network Extender. The Extender that you have is a 3G-only model. This will not support your A51 as the Samsung A51 is an LTE-only device with no CDMA option. Have you looked at our LTE Network Extender or tried using Wi-Fi Calling on the A51?

Thanks for explaining my A51 won't work with my old existing 3G network extender. I'll give Wi-Fi calling a try and see how that goes. The old extender still works with my wife's phone.

use of wi-fi calling works for my A51. My old S7 didn't have that option.

I do have a related issue - retrieving voice mail doesn't work at my location, and I was hoping connecting the network extender would help with that. Regardless, this issue is solved for calling. Thanks!
