991U1 dual sim? - Samsung Galaxy S21 Questions

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?

SHV-e160l uses micro sim?

I'm currently in Korea and just bought the LTE Note which uses micro sim.
Do you also have micro sim slot in your Note or it's just me? I haven't seen any note uses micro sim.
I've heard a few guys here use this note (the one was bought in Korea) oversea. Are those factory unlocked?
Thanks
Nope my SGH-I717D utilizes a full sized SIM
edit: May have misunderstood the question, sorry.

Dual sim adapter question

Hi everyone!
I noticed a large selection of dual or triple sim card adapter out there allowing us to have more than one sim installed in our phones at a time.
Just had a quick question if anyone has used them.
Do both slots allow LTE support? Or just the main slots?
I travel from Canada to USA and would love to find a sim option that allows me to switch between Sims when I cross the border, but I'd like to make sure LTE and all features work on both Sims, not just the main one.
Thanks for your advice!
Hi, I think that only the SIM that is into the phone takes internet, the others only make calls, you cannot use them for internet.
Cheers

Hi.
I bought myself no-brand adapter on amazon.
TL;DR version? My adapter allows LTE only on "first" sim. Second one is limited to HSDPA speeds.

No. Both sim chips are fully functional on my unit, only with limitation in form of LTE being present on main slot. Also, only one sim chip is active at any given time - that was exactly what I needed, so I don't mind rebooting my phone when I switch carriers. For active dual sim support a phone with build in dual slots for SIM is needed.

LG V10 - Dual sim versions?

How many dual sim versions of the V10 are there? H921N, H962?
All the dual sim versions have 2 sim slots and a 3rd slot for a SD card correct?
Also does the V10 dual sim version have a IR blaster built in?
I googled for information and photos but all I could find was info on the USA single sim model.
H921N owner here, yes, it has the two sim slots and the sd card one. And yes, mine has an IR blaster.
H962: 2 sim and 1 sd card slots, check. Ir blaster, check
Thank you for the replies. Anyone know which one of the dual sim model works in Colombia SA?
Here you can check it for Colombia:

LGH960A

The problem with Colombia is that some phones are just not approved to be put on there networks even if it supports the frequency range. My brother purchased a dual sim phone that had the supported hardware to run on the frequencies in Colombia but when he went to activate he was told that particular make and model could not be used in Colombia.
I know the V10 is sold in Colombia on Exito.com webite and it is the LGH960A model but I can not find any information on if it has dual sims or not.

S9+ Duos and Exynos - Dual Sim Dual VoLTE?

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?

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?

S8 already can do this. Don't think it's exception on s9

You can do that within settings itself.
Problem is not with switching Band of Data SIM; but having both SIM work at LTE simultaneously.

Rebrand S9+ and turn it to DualSIM

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.
