I'm on 5.1.9 but despite i activated the option only the Sim used for data traffic can actually connect to 4G. The other Sim seems forced and stuck in 3G at 900MHz (band 8)
There's no use for LTE on the phone sim unless you are lucky to live in China, India or Finland AND use a sim card of the view carriers supporting VoLTE in the OP6.
No sense reply. OP declares dual 4G on both Sim. My phone supports 4g only one sim and the worse the secondary sim is locked on 3G band 8
Are you using any custom rom? i faced similar issue on havoc rom

No. Pure stock 5.1.9
I had the same problem. But i went back to 5.1.8 and problem solved now dual 4g active.
Crazy but settings the phone on the English instead of my local language the problem seems gone.
I'm in America and I'm having the same problems after the 5.1.9 update, one SIM is always in regular GSM mode even with the dual-4G mode enabled.

That is completely false. Even T-Mobile in the US supports VoLTE. Even if it didn't though, it still allows for faster SIM switching since it was already on LTE.
Curious how you guys are checking it. Mine both say VoLTE and it seems to be fine for me.
I reset the network settings and it work for a few hours. The dual sim 4g instructions are broken .
Just got a S8+ from my brother and was having some troubles with it (can text/use data but not recieve/make calls) and found out that the cause was because the phone supported the 4G LTE band of my carrier but not the 3G band which is what my carrier uses for calls.
So how screwed am I? is there anything I can do to fix this?

Try in settings - connections - mobile networks and change network mode to 2g/3g or 3g mode and see if that works.
Note: I am still on nougat so settimgs location may be slightly different on oreo.

i've tried it and it didn't work as the specific model phone I have does not support the 3G band of my carrier (Freedom Mobile) so I can't connect to any of my carriers bands aside from the 4g LTE one

Is this your model
https://www.sammobile.com/devices/galaxy-s8-plus/specs/SM-G9550/
If so I would get in contact with your provider and see if is compatible with there network frequencies. apart from changing providers I am not sure what you can do.
If I've done my research properly freedom mobile is Canadian region apparently there are to modes home and away have you tried the away mode

yes that is my phone
i think away might actually work really well, how would i force it to only use away/roaming?
okay this is weird, so i turned roaming on, connected to a different carriers network (rogers) and i can text and data fine but still cannot make or recieve calls on a AWAY network....? does this mean it shouldn't be a network band problem?
it shouldnt be my sim card as my sim card works fine on my older phone fine (s7E) and i JUST got it replaced my the warranty service (to fix this problem, which it didnt). It shouldn't be the phone either as my brother put his sim back in the phone and he can make calls fine....... what is wrong here?
IT WORKED THANK YOU SO MUCH!!!
changing to rogers did not work (not sure why? maybe they use the same band is freedom)
however afterwards i changed to telus and i got calls!!

If you mean upgrade to Oreo I do have some minor issues at the moment nothing really major for me to worry about if I do upgrade. To save going way off topic here might be better to start a new thread or I could pm you if you like.
Hello
I have question... do any of you use it Samsung note 10+ SM-N9750 international unlocked with US carriers?
it's this model samsung unlocked for volte & wifi calling for any US operators? (like, t-mobile, at&t, google fi or for other? )
Thank you
SM-N9750 is a dual sim, unlock work on LTE but you will see 4G, it work in Canada and US however does not support VOLTE, wifi calling, samsung RCS does not work, if you want the RCS you need to download the Google message app, now there is a thread already where you can root the device and enable the VOLTE and wifi calling. hope this help.

From what I understand, you can call Tmobile and register your IMEI with them (unlocked device). After that VoLTE and Wifi calling will work, but not video calling.

are you sure i can call Tmobile and register your IMEI with them? and later will Volte and wifi calling work? Do you have confirmed information for this?
Which model note 10+ do I need to have? only with Snapdragon (of course I'm only interested in the dual sim version) will it also work on Exynos?
Thank you

I have BRI CSC (Taiwan). Wifi Calling button screeny attached.
Only issue is that carrier aggregation doesn't work.
As a added Note, VoLTE and Wifi Calling also works on my S8+ Exynos on XSA (Australia) CSC

Essentially, you will only be able to connect to 1 LTE band at a time, which means you will see slower speeds compared to a US Note10+. Basically, no problem with LTE data but could have slower data speed sometimes compared to US Note10+.

Thank you now I understand. But this is not a problem for me because currently I have the same because I have a note 9 dual sim with exynos. More important for me, it's wifi calling and volte.
Can you add a few screen from settings folder with settings wifi calling and Volte?
do use now dual sim ? One sim it's from t-mobile and have wifi calling and second sim card does not work on wifi calling?

Settings screenies attached. I am using both sims as you can see I have 2 dialing buttons.
AT&T doesn't open up VoLTE and VoWifi to non whitelisted phones, so it only shows on one sim. I just turn the setting off because it doesn't work anyways.

very good news I have t-mobile usa, so it should be ok.
did you use sim card a different provider from outside the USA?
Actually, T-Mobile is my "outside" sim card. I mainly use AT&T and switch to T-Mobile for reception/unlimited data.

Reviving an old post here...
Are you still using this device and still with AT&T and T-Mobile. Any long term issues or challenges?
I'm on the same carriers; T-Mobile personal (and primary) and AT&T (work). I'm most concerned about VoWiFi and VoLTE on T-Mobile. With AT&T, as long as it rings and I can get texts, I'm good.
Finally, I believe you said further up that you got it on ebay...any chance you recall the seller?
Thanks!

No usage issues at all. VoLTE and VoWifi works on T-Mobile. VoLTE works with AT&T. SMS and MMS works.
I got it from never-msrp.

I am not in a rural area or a dense metro area so those do not affect my receptions. Also I mainly use AT&T and switch to T-Mobile for data depending on reception.
Speed wise, it will be slower on benchmarks due to the lack of carrier aggregation (and b29, b30 missing for AT&T), but it doesn't affect my real world usage: chat/email, web browsing, music streaming, remote desktop.
Need a help here, please. I have a note 10 plus SM-N9750 with CSC tgy/tgy,tgy/tgy. Can i flash some unlocked global rom? Some stuffs are in Chinese and Samasung keyboard don't have Portuguese from brazil
Mine is N9750ZSU1BTA1, dual chip snapdragon 855
Hello everyone,
I bought a samsung s10e that I suspect is the AT&T version G970UZKAATT. This phone is supposed to come sim unlocked.
- Does that mean that when I insert a TMob sim card, will it reboot like the S9 and the TMobile logo will show up, then
the phone will work just like a regular TMob version G970UZKATMB?
- Will it have wifi-calling for TMob?
- Will it support all TMob LTE and HSPA frequencies e.g. band 71?
- Do all versions of the G970U support the same frequencies once unlocked just as these websites suggest?

Hardwares all the same. No, it wont boot with a Tmob logo. If you want it to act like a Tmob G970 flash the Tmob firmware.
I was just testing a S10e that has G970U1 as model (probably flashed) on the back says G970U.... I inserted an Ultra Mobile SIM card (TMob mvno) and it seems that the wifi calling works on the unlocked ROM .... So no need to flash TMob version, I believe.
Can anyone confirm wifi calling works on the factory unlocked version?
I have the g970u1 factory unlocked with u1 firmware. It has tmobile wifi calling. The only things missing are tmobile video calling and that rcs messaging I think. But, I flashed the tmobile u firmware a couple months back and the phone booted up like a tmobile branded one with the jingle and stuff. I didn't need those so I reflashed the u1

Thank you so much for confirming. I've just got my g970u1 factory unlocked and wifi calling with Ultra (TMob mvno) seems to work too. I tested using airplane mode enabling just wifi and I can still make calls
So I've changed my n20u u1 csc to others and I've noticed that each time I'm getting different bands that I'm able to choose that were not available at first...
Originally I had the vzw... But I switched to att csc then to dsh...
Vzw at the bottom only had nb260 and nb261... However with dsh csc.
I get dang near every band...
Here is the same device on vzw csc
Which tools did you use?
The band difference is due to carrier settings. Att uses direct bands than Verizon and so on. Some carriers such as sprint csc stuff opens more bands up than say Verizon setup does. So for the most versatility probably u1 unlocked firm would be the best

Most of the dialers are disabled on u1 firmware
You have to use the Google Phone app to access that menu: https://play.google.com/store/apps/details?id=com.google.android.dialer
If your carrier doesn't support these added bands it won't make a difference, you won't be able to connect to them unless for SOS calls if any carrier support them.
