Here's my scenario that I need to validate. Just moved my wife's phone over to Ting (Verizon Galaxy S6) and lost voice over WiFi functionality which is critical since we don't get a cell signal at home. Here is what I'm thinking.
1.) Move her number from Ting to Google Voice. Deactivate the SIM it was tied to.
2.) Activate my other Ting SIM with an new assigned phone number and install it on her phone
3.) Limit the account to data only, no voice/text
4.) Use Google Voice/Hangouts for all voice/text/voicemail, so essentially the phone will become a VoIP device even when on a cellular connection.
Does this make sense that this will work?
