Is Galaxy S9+ Duos with Exynos SoC Dual Sim Dual VoLTE or 2nd Sim Card is 2G/3G only?
So, you will want to use two different SIMs and speak use VoLTE for both?
I think it's possible. I have never thought of it this way, but it should work (although I do not have any evidence to back it up)
Looks like SIM2 won't do LTE at all according to phonemore http://www.phonemore.com/samsung-galaxy-s9-plus-sm-g965fds/specs/3886
2G network SIM2: GSM 850/900/1800/1900
3G network SIM2: Not supported
4G network SIM2: Not supported
Data network SIM2: GPRS, EDGE

Sorry, but Phonemore specs are completely unbelievable. It's simply bullsh...
Galaxy S7 Edge, Galaxy S8+ Duos and Note 8 Duos (all with Exynos) have 2nd SIM 2G/3G capable. Why could S9+ have only 2G network on 2nd SIM, if older models have 2G/3G?
Galaxy S9+ Duos with Snapdragon SoC supports 4G and VoLTE on both simcards simultaneously. Is it the same with Exynos version?

Unfortunately non of this devices you mention supports 3G. You have to switch in settings in order to have suport 3G,4G for sim 2 and vice versa.
S8 Exynos (G950FD) supported VOLTE on both SIM but not simultaneously; the other SIM would no longer remain in VOLTE network mode if you selected that mode for one SIM.
It's a shame that below $100 xiaomi phones now support VOLTE simultaneously on both SIM but Samsung doesn't. I hope S9 series does.

If you find out that it does will you let me know please. Currently sitting on the Mate 10 Pro which does Dual VOLTE and Dual SIM 4G, if the S9 can do this too then I'll definitely upgrade!

Well, my pre-order is expected to be delivered by 17th March; I can test and let you know by then.
Will voLTE be enabled by default on unlocked phones? Or will I have to buy an operator modified ROM to have the option to use the VoLTE or Wifi calling services?
Thanks
Its Hybrid Dual-Standby config so unfortunately only 1 sim can be primary at 4G/VoLTE and other can be only 3G/2G at that time.
Yea, I've just got my S9+ Exynos and I can confirm: when 1st SIM card is connected to LTE/VoLTE service, the second SIM card is connected to 3G network
No Dual Sim Dual VoLTE.
Shame on you, Samsung. Half year old Huawei Mate 10 Pro is better choice.

:good: Confirmed in Exynos : Only 1 SIM at a time for VOLTE while the other on 2G/3G . You can use either one of the Slots for VoLTE

Now we need to wait and see if the Snapdragon version can do it.
Another question, if you disable LTE on SIM 1, can SIM 2 then connect to LTE. Or do you have to swap the SIM cards over?

US Snapdragon variant is a single SIM model

I thought there was going to be a Dual SIM Snapdragon too?
Just easy though - *#*#4636#*#* For switching your SIM on data to preferred band @esvlc @madnav @overgonas @jano7878 @Fenny @RossTeagan

I second that.
I just received my S9+ (via renewal of my mobile contract) and received a dual sim one (check by inserting two sim cards, it does ask for both pins and let's me choose the sim card to use for calling), although it was never advertised as such.
However, it only shows LTE for the first one.
Considering that the dual-sim version is marketed as specific "Duos" devices, those might differ - but I wouldn't bet on it.

Can you chose which SIM accesses the LTE or is it only the Sim in slot 1 that can?

You can do that within settings itself.
Problem is not with switching Band of Data SIM; but having both SIM work at LTE simultaneously.
Hello everyone,
i could take this phone as an upgrade with my current plan, however it is of course single sim.
In EU there are any differences in the hardware between single sim and dual sim (other than the sim tray slot)?
Thanks

I wish it was that simple, could use that functionality tbh... Unfortunately you can not convert a single sim card phone into a dual sim card.
This is because the phone lacks the necessary connections/hardware internally for dual sim card support.
That's the M5 8.4 Chinese version with GSM / UMTS / LTE.
No official info in specs, but looking at photos of spare parts, it looks like the tray is dual sim.
If anyone could clarify.
Thanks.
SIM and sdcard
Does dual definitely not work? Some that are officially SIM & SD also work as SIM & SIM (especially with Huawei).
no. i already try it. just one sim works
Thanks.
I have the sm-G991Gu1 that I ordered from samsung in the US. Currently using it with a tmo aim card.
I've read that all s21 models are dual sim. Is this true? Can I put in another sim card from my European carrier and use it when traveling etc? (not esim).

Hi
I think your model 1 sim only , you can double check under settings / about phone if you have 1 or two Imei, also your sim try has one or two slots?
For those that have the S23U in North America, can you tell me if the phone will take two physical sims yet or do we only have on SIM slot and one eSim?
One and One
I'm not in US but it's same version worldwide. The sim tray has room for 2 nano sim. So you can have either 2 physical sims or 1 esim + 1 physical.
Hope this helps
My T-Mobile has ONE SIM card slot and ONE eSIM.
I converted my physical SIM to an eSIM without issue and have a normal SIM slot available.

Once the green SIM tray replacements are available in dual-SIM. I am going to order a couple and see if t he second slot actually works. The second IMEI is there, regardless of whether it is used for eSIM or dual-SIM. The DSDS apk is listed in system apps although I would like to get a hold of the DSDA apk to see if there would be a way to replace it through a custom ROM to enable dual active, even if it's just with one pSIM and one eSIM.

Would be fantastic if we can use real dual SIM but I don't put it past Samsung to have made physical changes to the device to make sure we can't use it.
