looks pretty straight forward to me. you wanted to add wifi calling to your phone, so your phone instead of saying " please contact your carrier to enable wifi calling! " instead it goes to a landing page on sprint where you can click a check mark to add it to your plan and submit it., does it actually work? you should try activating it and see if lets you add wifi calling to other devices running the latest public beta
9.0.2 would just tell you to call the carrier to add wifi calling to your plan, so i tried calling t-mobile
and they were like , we do not know how. because all our plans are supposed to have it
eventually wifi calling on t-mobile worked fine. i even sent a sms using my macbook pro at a tire store when my iPhone was left at home
No this is not WIFI calling on the phone, that has been working for some time now.
This allows your other iDevices to make/receive phones calls using Sprint even when your iPhone is not nearby, or turned off. (Using your iCloud account).
It works fine, I shut my iPhone off, and then used Facetime to make a call to a landline phone. The displayed Caller ID was my cell number. I'm not really sure when you would need this, perhaps if your phone was lost or broken.
Apparently there will be a charge in the future to use this.
BTW I'm using the latest public betas for both iPhone and OS X.
