Can X3 get HD Voice on ATT like my 950?

[Just_Me]

Looking to pickup a x3 to replace my L950. Does x3 get HD Voice on the ATT network like 950 already does? Do they have the same SIM card?

Nope I've tried, spent hours with it. I can get HD voice on the Idol 4s, 950 Dual sim, and 950 XL. For the X3 I could not figure out what needs to be in place that I have not already done for those others to get it to operate/provision correctly.

Second this. HP considers the X3 to be "AT&T Certified" but this doesn't mean that it's compatible with every AT&T feature. FWIW, HD voice was also a non-starter on T-Mobile. No VoLTE function on either US carrier.

It's AT&T IoT certified. I think that is the "certified" they're referring to.
