Message from AT&T About My Phone Not Compatible?

Mine is exactly like Saijin’s!

@cpangracs - do you have VoLTE icon in your top status bar? @Saijin_Naib - does not have it even though it is enabled in his settings.

Having it enabled in settings does not make it operational unless the icon in the status bar at the top shows.

Check this image above - it has the icon at the top which shows VoLTE as being on.

Maybe (just maybe) it is only on AT&T :crossed_fingers: :slight_smile:.

I do, when I turn=off WiFi calling, I get that same symbol.

Could you share your screenshot as well.

Interesting, I do not. Could be my market location, or possibly the age of our SIM cards…

Cool - thanks for sharing. This is the 2nd case of VoLTE icon showing up on AT&T phone. This could very well be a super-early Christmas gift from AT&T :slight_smile:.

Any other AT&T users seeing or not seeing VoLTE?

Could be, I know my sim card originally was from a prepaid AT&T GoPhone, so that’s my story!

I do not see VoLTE. Maybe it’s because my SIM Card is old (got it back sometime before the first Pixel 1 released)

My sim card is also from my old Galaxy Note 8 from att, so that may be the key?

I have seen some references online where VoLTE works if your SIM was there in a VoLTE enabled phone earlier. @Gatlin_Newhouse - could you try calling AT&T to enable it for you?

I have voLTE on TMobile :+1:t6::+1:t6::+1:t6:

I think I need to get a new SIM card per this support article:

SIM card compatibility
AT&T HD Voice requires a SIM card that is UICC-G or higher SIM card installed in your smartphone to enjoy the rich calling experience of AT&T HD Voice. Want to make sure to find out if your SIM card is HD Voice compatible? In the SIM card number, look for the digits 27 or higher in the 9th and 10th positions.
Don’t have a compatible SIM card? Get one at an AT&T store.

My IMEI number does not have 27 in the 9th and 10th positions (it has 00)

Will Wifi Calling work on the Teracube?

Traditionally AT&T has enabled Wifi calling only on AT&T branded phones. However this is a new world recently :). So maybe.

As mentioned earlier, T-Mobile gives both VoLTE and VoWifi on Teracube and many other BYOD phones.

Called AT&T. Updated my device IMEI. Then they couldn’t enable VoLTE for me because the Teracube isn’t certified with AT&T.

So I think had I had a Samsung with VoLTE / Wifi Calling already enabled and then moved the SIM card to my Teracube it would work. But since I had a Pixel 1 XL and Huawei before my Teracube it cannot be enabled until certification happens or I get a phone IMEI with both those features enabled

Mine has the 00 as well. Only shows LTE on upper right corner, but I have the 4g toggled on, as well as, the wi-fi. Seems the ATT community has been talking about this for about a year now! BTW, my reseller is PureTalk for the ATT network, so I would have to contact them for an updated SIM?

Mine has a 00 in the 9th and 10 digit as well, yet VoLTE seems to work. It’s very odd.

Just my 2-cents of experience with AT&T and jumping devices, first a little background:

My last “Officially Certified” AT&T phone was the Moto-X (xt1058 “ghost”) on Launch, direct from motomaker (google) assembled in Texas … paid in full 2013. Not subsidized from AT&T.

Since then, I’ve used all kinds of phones, none of them certified. I’ve never registered their IMEI with AT&T (not required under their TOS, but they like to have it anyways, my advice: don’t give it to them if possible). As long as the frequencies line up, everything seems to usually work. Frequency Check.com is a good resource to see if a device will work properly.

If you upgrade your SIM card, in order for their network to enable & recognize VoLTE on that sim, you will need to use a “Officially Certified” device for about 20-30min. Any AT&T VoLTE smart phone works. (another reason to keep a cracked screen device IMHO)

I’ve heard from other people (on XDA and such) that the BYOD business model is forcing AT&T to end this, my SIMs are current so I have no idea if this is true.

Work for me is starting back up so my time is limited, and I will end up with a required company work-phone. If I get around to putting my Teracube back to stock I will use a network tool app (NetMonitor PRO by Vitaly) and get a few log files then get back to everyone; unless someone beats me to it.

Sorry about the text block, the video meeting/training I am forced to endure is boring.
