    WI-Fi calling

      Hey all,


      I was wondering if when the iPhone 5 is officially released/Available on T-Mo will WiFi calling be supported? For me, this is the deciding factor between the iPhone 5 and the Galaxy s III. and if so, will it only be available on ones unlocked and sold by T-Mo or will any unlocked iPhone 5 work? I’ll just go get one now from apple if so.

          With T-Mobiles new un-carrier strategy that they are going to I don't think their stores will directly sell them in their stores or have it branded to T-Mobile.

          They will be more a BYOP carrier (Bring Your Own Phone) and uyou can buy full price what they have or from anywhere else.

          That being said I don't think they will have wifi calling at all on the iPhone.

            It will more than likely be up to the manufacturers. T-Mobile open sourced WiFi calling since 1997.

              I can't find anything open sourced.

              And for IMS wifi calling based on SIM security I am sure there is proprietary and closed source code.

              But if you can point the the code that would be great.

                Let me see if I can find it. Been a long time. I know Google had the source since 2007 and never implemented it.

                  I tend to believe that T-mobile will have a software update file which while allowing LTE will also allow Wi-Fi calling. I remember vividly the statement when T-mobile announced the partnership with Apple. The CEO then said there will be some unique features that will make a compelling reason for people to buy unsubsidized iPhones to use on the T-mobile network.

                    Chances are the iPhone will implement IMS to work with the iPhone.  It's completely software driven so it doesn't require special radios.  I believe IMS has been implemented on all devices 4.1 and above.

                      Thanks guys. I suppose we won't know until it's known...... Let's see if the T-mo mod responds with some insight.....

                        Don't expect it.

                        Typically the rumor sites have that knowledge way before any of their reps would.

                        Always makes me laugh.

                          Hi fyurmama,


                          This is a good question. I wish we could give you a good answer… we're not sure at this time what we'll be carrying for Apple products and what software it'll support.  We can definitely add Wi-Fi calling to the wish list though. It's a great feature.

                            Jessica thanks for your post. 

                            Please convey to the powers that be, that Wi-Fi calling using iPhone on T-mobile will be the Unique Selling point (USP) for T-mobile. T-mobile has the weakest PCS coverage in the US (I Know your CEO likes to think Sprint is worse, I accept that for AWS not PCS).So a Wi-Fi calling feature will be the factor that popularizes iPhones on T-mobile. There is Bobsled App for Wi-Fi calling, but to receive calls in Wi-Fi area only Wi-Fi calling from T-mobile can make the difference.

                              Since the iPhone has bee noffically announced... how about Wi-Fi calling now?



                              • 12. Re: WI-Fi calling

                                We’re sorry, but this Wi-fi feature is not supported on iPhone 5.

                                  And how do you know that?


                                  In any case, Apple will not allow T-mobile to announce that. Here is a reference to this topic:

                                  ".....The carrier also announced that its version of the iPhone 5 will not initially support T-Mobile's Wi-Fi Calling technology. Speaking with Engadget, Sievert said that Wi-Fi Calling "is not coming" at launch. Pressed on the issue, Sievert said that T-Mobile "loves its Wi-Fi Calling feature, and I'll have to leave it at that."
