Both 4G Volte sims - Samsung Galaxy S7 Questions and Answers

Hi Guys,
I am using a 4g+3g sim in my s7. I am planning to upgrade the 3g sim to 4g. Will both 4g sims work fine simultaneously?
Thanks

You can have data active only on one SIM. Also, no phone supports dual volte.

Thanks for replying. I am not interested in data. Can we enable 4g sims at the same time so that both can receive normal phone calls?

Well 4g does not support calling its volte that supports. As mentioned earlier no phone supports dual volte connectivity at the same time. As of now there is no phone chipset that does this.

now new update from s9 firmware brings dual4g support,seems we can do that by flashing the same csc to s7 oreo update

Sorry to bring you bad news but what you trying to do isn't possible,
at least from what I've gathered.
I'm on the same boat and am really upset that Samsung makes things harder
every year and this time around CSC is totally different now.
Please let me know if you find any good news.
Switch to the canadian model and you'll have everything but root, i'm sure theres plenty of people that will do a straight swap.

download the rogers firmware from sammobile and join batstock rom telegram support channel. The OP can help you out. All you have to do is upload a file from the download there and he'll add the csc to a flashable twrp zip that you can install to fully enable all rogers features.

I got bad news for you. VOLTE and Wifi calling only works on android phones that has been bought from Rogers. I have the unlocked version from Samsung.ca and it still didn't work.
Correction: The only unlocked phones that work on Rogers VOLTE and Wifi-Calling are the iPhones.

i see.
next thing you want to try, make sure your build.prop product name matches that of the rogers phone.
also, my carrier disables feature if it detects root such as wifi calling. if you have magisk hide and an app for wifi calling uou may want to try hiding those apps from root.

I already called Rogers tech and VOLTE and WIFI Calling don't work on Android phones that was not from Rogers. No matter what you do, its the IMEI number that triggers their system to enable it on their end.
Unfortunately all carriers including Bell, Telus, Fido, Virgin and Freedom Mobile do this.
if it trully is incompatible, it is more likely to do with the difference between th band availability between the international model and canadian model... a quick google search will allow you to compare band availvility between phones and what bands are used for the carrier.
i don't believe it though, that just makes it hardee for them to aquire clients with existing handsets.

Flashing single SIM software on dual sim

I've got dual SIM version 955FD and would like to flash UK EE 955F software via odin so I can take benefit of VoLte function. Is this possible and will both SIM still work?

You can't possibly do that since many extra features will be present in the dual sim firmware than compared to the single sim firmware . Play safe :laugh:

The dual SIM variant uses the SAME firmware as the single SIM variant. You CAN flash other firmware with no problem. You will lose nothing at all.

Service is fine, just as it is on my F s7 edge and note 7 FD .
I dont think VoLTE works with it out of the box but that's not overly important to me anyway nor is wifi calling etc.
Id rather lose some unimportant features that i dont care about then get stuck with a locked bootloader piece of junk device that i cant mod if I want to

Features such as, Settings/Connections/SIM CARD MANAGER which allows you to chose from one SIM or both and more. I believe the normal version does not have this section, it does not make any sense. Can you confirm?

Yes and no. WiFi Calling and all of the bloat will be there and it will work as long as AT&T doesn't realize you are using a device you didn't purchase from them. Once they realize you didn't buy your device from them, they will disable your line from using WiFi Calling.

I'm not sure. I was never an AT&T customer.
After giving my girlfriend my S9 Plus and her fighting with AT&T over the WiFi Calling b/s, because they would keep disabling it on her after switching back to her S5 Active to get it re-enabled. I finally got her to switch over to T-Mobile.

I can't complain about the service I have had with T-Mobile. In Virginia, it is better than most other providers. Blacksburg now has band 71 deployment and Hampton has pretty good band 12 service. In upstate New York and Canada, I haven't had any complaints either. Going up and down the east coast earlier this year, I didn't have any complaints, even after traveling through West Virginia. Obviously, other areas may vary.
On AT&T though, my girlfriend had no service in her Hampton apartment, no service inside of NASA Langley, and no service at her parents home in Itmann, WV. However, on T-Mobile, she at least has good service at home and at work now, including inside of the buildings.
Well I flashed this ATT on my unlocked 650U1 and nothing ATT showed up, not even boot logo. It showed the correct model as G965U and version BRJ5. Loaded everything in odin. Any suggestions?

The latest for the G955U is DRL7.
The ZSAB update is for the G955U1.
You will need to flash over to the G955U1 CL2 firmware in order to get to ZSAB. You will lose wifi calling and voice over LTE if you do so. (on AT&T)

No, AT&T requires its users to be on their branded phones. T-mobile is a lot more lenient when it comes to phones.
