Does anyone know how the new unlocked devices handle carriers like ATT for calling features, like WiFi Calling? The Pixel works as long as your account is activated for WFC

If not, will you be able to flash carrier former on an unlocked device to get features working?

I don't know how that works with ATT - I know that my G975F does not get those calling features - but considering the unlocked Pixel Does get Wifi Calling and and Enhanced LTE on ATT, it is possible that an Unlocked Samsung Phone will too. (if it were a tmobile phone, it would not get WIfi Calling on ATT - but I honestly think the Unlocked Samsung Might) Good Luck.

Wasn't sure ..... It was strange in that ordering the unlocked from Samsung have 600 credit for a Note 9 , but only 300 for an ATT ???
I have accounts with ATT and TMO ..... So I thought I know unlocked might be best

But I don't want to end up with no calling features on either

Worst case i would assume you could Odin the att files on the unlocked version to enable it. That's how it's been the last few years anyway with Samsung devices(snapdragons). I know that those features work on the unlocked with t mobile.

On T-Mobile I get WiFi calling and volte with my old Note 9 and current S10+. Never had an issue. The only thing you do t get is that aggregate LTE capability. But I don't really notice a difference in speeds. Not sure how it works with ATT.

I can tell you that the Unlocked S10+ does NOT get WiFi Calling or VoLTE on AT&T.

Did you try any of the "tricks"? Like Odin flashing carrier firmware or making sure that ATT had your IMEI in their database or even putting an ATT device IMEI in your account settings?

Because if you do nothing and expect WiFi calling on a non ATT device it will never work

Odin flash carrier firmware. I'd rather just buy the AT&T version and not have to go through the trouble.

Yes, AT&T has my IMEI in their database. I even gave them one from my AT&T branded S9+, but that trick doesn't work anymore. They read the IMEI directly out of the device at some point when it connects to their network.

I called support and asked them to verify that I had WiFi calling and VoLTE provisioned, but then when they saw the IMEI was from an unlocked S10+, they told me it wasn't supported.

I did everything I could short of flashing the carrier firmware, which I didn't want to do because I was considering switching back to Verizon. BTW, WiFi calling and VoLTE works fine on Verizon with an unlocked Samsung S9 or S10 without having to flash anything! It's AT&T that's being difficult.
