I wanted this to have its own thread so people can realize how amazing this voip app is from the apple app store. It is the Vonage mobile app and it is completely free. For those on the $30 t-mobile plan or similar (5GB data, unlimited txt, 100 min calls), this vonage app helps tremendously to avoid going over the 100 minute allotment. If you have good network data speeds or surrounded by wifi, the free vonage app gives you 3000 free minutes a month to any United States phone number and it even spoofs your calls to your mobile number (when the recipients gets your call it shows your mobile number). I have been using this for a month, and the calls are great using the t-mobile network. I had a 1 bar on my phone and the data speeds was good enough. Keep in mind, that the vonage app is only useful for outgoing calls. If someone calls you, the vonage app doesn't have a call forwarding feature(vonage does not assign you a phone number) to redirect the calls to the app. Usually if someone calls me, I decline it and call them back using the vonage app. I don't get a lot of incoming calls, so it's not annoying for me. I hope this thread brings awareness to people stuck on limited calling but rely heavily on their network's data plan or wifi.
