Dual SIM / Google Fi - OnePlus 8T Questions & Answers

Does anyone have any clue as to whether or not I could run a Verizon SIM and a Google Fi SIM on this? I currently have the Google Pixel 4XL unlocked using a Verizon SIM and a Google Fi eSIM and was looking to get the 8T as a replacement. But I need both SIMs to work in the phone.
I travel the US and in many places I have spotty signal on one or the other and need to be able to switch between them.
I have been reading that the 8 and the 8 Pro have had (or still have?) issues with the dual SIM not being available.
TIA

If you have the esim for fi and have the unlocked dual sim you should be fine. I converted my 7t to the international dual sim and used a T-Mobile and a Verizon sim without issue. If they didn't have dual sim available in assuming they were carrier locked firmware

Are you in the US or elsewhere? Have you been able to modify your network manually without switching the SIM back to a Nexus device?

Dual SIM U11 on TMobile & At&t (USA)?

My googlefu isn't turning much up on the dual sim version of this phone, but hardware seems to be almost identical to the standard version.
1)Does anybody know if the international version would work with TMobile WiFi calling? Volte?
2) is the SIM2 slot 2g only or is it 3g? (This would be my att sim card, which disabled their 2g network)

Same questions here. I'm interested in the international version with 128gb memory and 6gb RAM. I want to use two Sims in this phone, one TMobile and one AT&T.
I really need TMobile wifi calling to work out of the box on this phone. Has anyone been able to get an answer on this?
Thanks in advance for any help!

Dual SIM 4G+3G or only 4G+2G ?

I'm contemplating a purchase for a Mate 9 with dual SIM capability ( from Kogan Australia). It's advertised with dual SIM. For me, the secondary SIM would only add value if I can use it on 3G, while I keep the main SIM on 4G.
But in some documentation, the secondary SIM only supports 2G. Has anyone successfully used Mate 9 with 4G+3G SIM combination.

For sure....! I also think 4G+4G can work...
If the Australian version is the same as the European version it will support 2G, 3G and 4G on SIM 1 whilst SIM 2 will support 2G and 3G.

3G would be great on SIM 2. The problem I'm trying to solve is that our Australian telco ( Optus ) has severely degraded its own mobile network, to the point where we can't receive voice calls anywhere in our suburb. LTE used to work well, not any more. On the other hand, they improved somewhat on their 3G network. My wife is still in contract with cheap plan. So I could arrange a dual-SIM where SIM 1 is on 4G with another telco, while SIM 2 stays at 3G with the old telco. Things may improve for their network, or the company is going down, we shall see.
4G/3G is how it does it.
Both will support 4G but you'll need to put the switcher setting on your homescreen so you can switch quickly - you can't have both on 4G but both will support it. The other will be able to use 3G.

dual sim issue... Verizon/tmobile

I've had duel sims running with no issue since I bought the phone. Now today all of a sudden the Verizon sim will not work in this phone. I've tryed switching positions.... And by itself... NOTHING... I put the Verizon sim in a Verizon phone and works fine...
Any settings or somthing I can check? This phone is begining to be more trouble than it's worth.
Are you sure a Verizon sim will work with this phone? Usually Verizon runs on the CDMA network. If the phone is GSM only, the Verizon sim reverts to voice over LTE. As far as i know, this phone does not support voice over LTE.
I'm just guessing.
An educated guess though
But check the data network settings.
Play with the dual sim settings.
Sometimes one of my sim slots just disconnects for no reason

It seems like the vivo nex snapdragon 845 version (the pop-up camera one) is missing a band 13 for 4G lte. Does that impact the connectivity in any way on Verizon?
Also is your model the chinese rom or the global rom?

OnePlus 8 US unlocked version NO wifi calling option/ no DUAL SIM SUPPORT yet

Just got 10.5.7 on my OnePlus 8. No DUAL SIM SUPPORT yet. Still no WiFi calling feature is showing up with VERIZON WIRELESS sim.
Any one has same issues?
All I know when I had my unlocked OP 8 Pro on T-Mobile wifi calling absolutely was there and worked. Sounds like Verizon isn't provisioning that with the SIM to me..

Correct I sent mine back last week... I wanted to keep the phone but wasn't ready for prime time for verizon.
