Samsung S6 calls only in 1x, not 4g

[Waylonk3]

Hello, my phone will only make calls in 1x, not 4g like it used too. It's a Samsung s6.  Thank!

Waylonk3, I am here for you to help ensure that your calls are able to be made. When making a call, this will respond to the tower and connect to the 1x network. This will be standard. Are you making standard calls or Wi-Fi calls? JoseL_VZW
