So I have an iPhone 5 on T-Mobile and am wondering if there is a way to use T-Mobiles complementary Wifi Calling with my device. If not, are there any apps or anything that will allow me to call, except using my phone number? I really don't want to download a third-party app and then have friends save two numbers for my phone, 1 for calling and 1 for texting. That just seems kind of stupid. Thanks.
Wifi Calling on iPhone with T-Mobile?
You can use your current phone number with Google Voice, which has an app called Talkatone on the App Store.
Have you tried Viber? Http://www.appfavour.com/social-networking/viber-free-phone-calls-text_382617920/ This app lets you communicate with other Viber users for free, and it separate your contacts from Viber contacts.
