Is there a VoIP/Wifi-Calling app that allows you to use your own phone number? (that is, the cell phone number that is already assigned to your device by your carrier)?
I've been poking around online and it seems almost all force you to take on a separate phone number for the VoIP/Wifi-Calling app. I've only seen one claim that Vonage allows it, but none other. Ideally I'd like more than one to choose from. Haven't tried Vonage as of this writing but going to try it right after posting this question.
I tried Vonage. It does use my number for outgoing calls, but incoming calls still ring the phone app installed on my phone by Sprint. I have a feeling that acejavelin is correct that my only option is call forwarding to another line (like google voice) which is inherently set up to work over IP.
Seems to me, ideally, if I could just actually replace the phone app that my phone came with, that would work, if I could find a phone app that can do that and that does everything I want. By the way, the main reason I want this is to be able to use Wifi calling when I'm in a location with a weak signal but available Wifi. Sprint offers Wifi calling but they have some bugs; I've escalated to Sprint's Engineering team, but it does not appear they are going to fix their bugs anytime soon.
881 + [country code] + [your mobile number]" That means people have to dial "881 + [country code]" before dialing my number, if they want the call to come in via FreeFly881 app.
