I strive to carry as few phones as possible. Once Visible will allow their current customers to switch to eSIM, I will be able to move my Life Wireless number to my primary phone. Until then though, I needed a service provider that would not try to do Caller ID, but instead just show the number calling, and allow me to make the decision on answering. Callcentric does not do this. Because of this, I use LocalPhone to substitute for this feature.
This US local number will ring my SIP client on my cellular phone. This number works with my Google Voice account for all unknown callers. When I am not home, I will use cellular data for the call.
