No you don't. You are confused.

iPhones (all of which are unbranded) and recent Nexus devices support TMobile wifi calling.

Unlocked 950 & T-Mobile WiFi calling TMobile Wifi calling does not work on your 950XL in any way, shape, or form. You are confused. (I'm discounting the possibility you have some insider firmware, hack, etc. installed on your device.)

It isn't a cricket problem. Dual SIM WP devices do not currently support VVM, period. Try YouMail.

Indeed. But *that* is exactly what would be required -- not wishful thinking that AT&T and Microsoft will make some kind of agreement, or that some tech can provision a device correctly, etc.

In the UK it's probably the case that the only "open market" devices they're familiar with are single-SIM variants. Built-in VVM is unequivocally not supported on dual-SIM WP devices currently.

Unless and until the WP OS supports VVM on dual-SIM devices, nothing AT&T does will get VVM working on dual-SIM 950/950XL handsets. This is not a provisioning issue, it's an issue with what WP supports, and its built-in VVM is not currently supported on dual-SIM devices. Period.

The notion that the carriers will "code the backend" to work with Windows Phone's VVM is backwards. It's not up to the carriers to adapt their systems to support WP. It's the other way around: supporting VVM on a handset means creating programs on the device that work with the VVM systems...

Incorrect. Support for T-Mobile and AT&T VVM is built into the OS but not enabled for dual-SIM configurations. The issue is ENTIRELY on the phone itself. If Microsoft decides to make it work some day, an OS upgrade will let it work with no actions required from the MOs.

Inaccurate. WP's built-in VVM does not support the VVM standard Verizon uses. The Verizon VVM app doesn't replace/override any built-in WP functionality. I think the Verizon WP handsets support VVM on TMO and AT&T but I concede it's possible Verizon requested that support to be removed. My...

None of those statements are true. (1) T-Mobile/AT&T VVM *is not* carrier software on WP (2) T-Mobile/AT&T VVM *is not* burned into any carrier-specific WP firmware (3) T-Mobile/AT&T VVM *is not* an app in any way, shape, or form VVM for T-Mobile and AT&T is part of the OS and exists in every...

VVM for AT&T and T-Mobile is not an app. It is built into WP (but only functional, at this point, on single-SIM devices).

Your 920 was not dual SIM. Your 950XL is dual SIM. WP does not support VVM on dual SIM devices.

Incorrect. It has everything to do with dual-SIM. WP has built-in support for VVM on AT&T and T-Mobile. However this support is not available on dual-SIM devices. If you have an AT&T branded 950 and can't get VVM then there is a provisioning issue because the AT&T branded device is a...
