Dual Sim in Artemis - any experience?

Hi,
I just got a good offer from my broadband provider to get an extra sim where I can make landline calls for free, but calls to mobiles are then very expensive, so I want to use my old contract for mobile calls.
Anybody out there got any experience using a dual sim (I read it involves cutting ).
I also heard that you can get some kind of "super SIM" where you can copy 2 sims onto one? Does this really work?
Cheers

I have a dual SIM adapter. I use my 1&1 SIM card for free landline calls and have free minutes for my mobile calls from T-Mobile. I use an analog adapter from hot-wire-telekom.de - digital adapters can change between the SIM cards a little faster but consume more power, heard that it can be more than 30% in some cases. I didn't want to risk that, there are nice tools out there to assign that function to a hardware key, that way you are actually faster than digital dual SIM cards.
If you have a digital dual sim adapter you have to go to your sim toolkit menu to change between the cards, with the analog adapter you simply switch the gsm unit off and on again, it takes about 20 seconds until you have your signal again.
I did cut my card, actually broke my first card because I didn't pay enough attention. Hot wire telekom offers to cut your cards if you send them to their shop, I think that was for free or costs only a few Euros. I'd recommend that since cutting it was a little difficult. The card of a friend didn't work that well, sometimes it switched from on to the other by itself.
I'm very happy with my card and use Smaato Cost to tell me how much I spent. It's a program that tells you how much money you spent making phone calls, very nice program! Send me a PM if you need some information in German.
Copying two sim cards on one is only possible when you have a version 1 sim card (as far as I know) and you don't get one of these, they are veeeery old. I think if you have two sim cards that are older than 5 years you might be able to copy them on one card.

Hi Registerme,
thanx for sharing that info.
Sounds like the analogue dual card is the way to go - the cutting service sounds quite a good option.
Would however much prefer not to!
Forgot to mention - at work I have a TMobile "Twinbill SIM" - by entering 2 different pins the call costs are switched between Busuniess and Private (switchover working via SIM Tool Kit in the cell phone menu).
I was wondering how TMobile manages this.
Anybody out there any ideas?

This is actually a dual sim card with two phone numbers, see here: http://www.t-mobile.de/business/twinbill/0,10205,14411-_,00.html
They used to have analog cards but use digital cards now.

Which Dual Sim Adaptor to get

Hi Guys,
I'm looking forward to buy a dual sim adaptor which preferably dosen't require cutting of sim cards and is durable.....that leaves only one type of dual sim adaptor which makes copies out u'r SIM cards and puts it on single sim card like this 12 in 1 Sim Adaptor
However, this type of adaptor isn't compatible with some sim cards, So is there anyway of knowing before hand weather my sim card's can be copied or not?
Let me know, if anyone has tried this kind of adaptor..
Regards,

Dual-Sim G4 questions

So I decided to buy a G4.
I know about the boot loop issue, but LG fixes it if it happens, so that's okay.
My Samsung devices all had issues (multiple), so yeah.
Anyway, I have a couple of simple questions regarding the dual sim edition.
They cost the same in the country, so I figured I might buy the dual sim one...but...
- Does it have the same, latest (MM) firmware?
- Do you get any annoying notification if you just use ONE sim card in it?
- Does it still have a microSD card slot besides the dual SIM slot?
The thing is, MNOs are becoming popular in my country.
So you can finally get cheap mobile internet, but on a separate sim card, of course.
This way I could just toss in a second SIM once I get a good deal, and hook my mobile data on that.
Thank you guys!

1. Yes it has lastest marshamallow.same as single sim variant.
2. 2nd sim will show message as "service disabled" if you disable 2nd sim
3. yes it has micro sd card.but it doesn't support wireless charging.

use 2 sims and micro SD card

any way to use 2 sims with micro sd card ?

From my understanding not on newer Samsung dual SIM phones.
You might be able to use one SIM and the e-SIM.

You can use eSIM plus nanoSIM on s20 ultra and that will leave the microSD available. A guy on you tube showing the eSIM setup details sort of confirmed this.
I will update when I get an Ultra.
But that seems to be one of the biggest features on s20 Ultra this eSIM support and microSD with two numbers

From what I've read it may depend on the carrier software/CSC, as to whether you can use another SIM card along with the eSIM? But I can't see anything confirming that so far besides user posts at some places which seem to be more speculation than anything.
All that I can confirm for sure is, that it is possible. My carrier (Telstra, Australia) offered me both a standard SIM or eSIM when ordering, in which they said I could use another SIM freely along with the eSIM (eSIM is what I chose) I hope that's applicable for all.

They talked about this on the Samsung Forums. The international version has a hybrid slot allowing 2 nano Sims or one nano sim and MicroSD. In the US version one nano sim and MicroSD. If you use the ESim and nano sim only one can be used at a time not both. Like you can't be calling on one and texting on another. At same time.

The ability to use only one line at a time is not particular to the eSIM. My Note 8 has two nanoSIM cards and same limitation applies. When I talk on one of the cards the other is disconnected. Data comes only on one of the cards. Indeed only one has 4g connection.
I suppose s20 have similar limitations. I think this is limit as there is only one radio.
The gain is that both SIM are registered in the network and both can receive calls or be used to make calls at a given point of time but not simultaneously.
In my case both cards go to the same operator. One is from work the other is my personal number.

It works on the EU model SM-988B/DS
One nanoSIM + eSIM + MicroSD works.
I got my S20 Ultra last night and now have 256GB storage 128 built-in and 128GB SD card.
Now I have to figure if UHS-II benefits me or I stay with slow big cheap UHS-I card. Perhaps I will go to 400GB card.

Question Dual sim tray disabled in software (SM-S901U1)?

Hi all,
I recently purchased a Galaxy S22 (SM-S901U1 - S901U1UEU2AVF7) from Google Fi with the intention of using 2 physical SIM cards and 1 eSIM on it.
On Samsung's website (https://www.samsung.com/global/galaxy/galaxy-s22/specs/) it says some models have "two Nano SIMs and one eSIM".
Upon receiving my S22, I took out the tray and noticed it could only fit one physical SIM card, however, looking at the sim card slot through a stereo microscope it looks like there are SIM card contacts on either side of the slot (meaning the physical connection is there).
Also, doing a `*#06#` shows IMEI1, IMEI2, and EID; which to me signifies the phone itself could support the "two Nano SIMs and one eSIM" option.
I went ahead and bought an S22 replacement SIM card tray with support for 2 SIM cards, and put another SIM card on it but can only see "SIM 1" and "eSIMs" under "SIM card manager".
It honestly looks like Samsung disables the second SIM card in software for the US market.
Can anyone here confirm my suspicion and if so, do you know if there is a way to change that software restriction? Thanks

The second IMEI is specifically for the eSIM, the EID is what one would consider the ICCID if it was a physical SIM.
Only models outside the US have the option of a dual physical SIM.

Thank you for your response.
Do you know if that is a limitation imposed by hardware differences (i.e.: the US version is missing a radio or SIM card slot) or is it imposed by software?
(I have purchased a dual SIM tray to put into my S22)
If it is the latter, would flashing a ROM from a region with support for dual sim cards (and the same processor) enable dual sim cards for the S901U1?
Cheers

I wouldn't know if the hardware doesn't support it.
If I had a guess, it would probably be locked at the baseband with software, similar to the OnePlus 9 Pro. The latter was later confirmed by users; even though the hardware was the exact same across all devices of that model, changing to a different ROM changed nothing as the baseband retained its state.
Also, most if not all non-US models use the in-house Exnyos SOC, so finding a stock ROM to determine this would prove difficult.
Someone might take a poke using QPST and other diag tools. I can't currently do so myself.

Hello TS! Do you have an update here?
