i doubt it very much the hardware is there. As some user have flashed WETA rom, the phone dialer shows up on the SM-T830 WiFi model! You could try flashing WETA and then try a sim card!

I'm realy not sure if all necessesary hardware are there but at least the sim reader and the sim space in the tray yes. I will try later with weta rom. Thx

I think the WiFi Model has the space for the bigger tray that includes the Sim. They don't want to redesign the tablet because of the little space they could be used. Maybe is the Sim reader is there too.
But I don't think that the WiFi model is capable of LTE or 3G. Samsung probably left out the modem and the antennas to safe some money. The WiFi Model is 70€ cheaper than LTE version.

I'm just necroposting because this is a very common theme, and it needs to be put to rest once and for all!
Not really. But there is a 'black box' section of the firmware and hardware that only Qualcomm has access to, the technicalities of which are under government regulation, both USA and Internationally. That is why the major portions of all Qualcomm equipped devices are actually written by Qualcomm itself, and other processor (SoC) manufacturers likewise.
If such information was disseminated to mobile device manufacturers, it would leak, and that would compromised the entire cellular system. The wifi only is nearly identical to the 4G LTE, but you will never get firmware loaded that will open up the cellular modem.
And if you actually accomplished such a task, it wouldn't be long before federal authorities were interrogating you on how you did it, and debriefing you to never mention a word of it ever again, nor using the knowledge in any way, under penalty of being legally banned from all cellular networks, permanently!
If you dig hard on the Qualcomm site, and pass a few security checks, like demonstrating you're an actual mobile device developer, you will run into these stone walls where no one is allowed to pass.

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
Cybercontroller
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.

[Q] SIM Card Connector?

I read online that some Chinese resellers have managed to solder a SIM Card Connector to the Incredible's motherboard that originated from Verizon USA.
Has anyone heard of this? Can we just solder a compatible SIM Card Connector onto the Incredible or are there other things that need to be done?
This would allow the Incredible to be used on their local CDMA network.
Attached are pictures of the authentic finished product with the SIM Card Connector.
I took a close look at the motherboard & indeed there are solder contacts for the SIM Card Connector.
Was wondering if one of those SIM Card Connectors available online & attached here could fit in that slot.
Anyone able to advise on this?
I hope to use my Verizon HTC Incredible on the China Telecom network in the future.
Please advise me...
Google gold card. There is a way to format a sim card to be used on overseas CDMA networks.
How does that thing work, and does it work?

The reseller was touting that it will work on the China Telecom network. I might need to verify if he meant the GSM or CDMA network.
I was wondering if the hardware for Incredible is similar to the Sprint HTC Touch Pro 2 in that it supports dual radio? Sprint's TP2 has CDMA as primary & GSM/WCDMA as secondary cellular radio.
That could explain why there is a SIM card slot in the Incredible.
On a related note, I discovered that the reseller mentioned something about writing something to the phone related to the following:
Basic communication functions: IMSI, ESN, A-Key ​EVDO Internet access: AN, AAA​ Does all these make sense?
I got the above information from this article: http://translate.google.com.hk/tran...=lPv&rls=org.mozilla:en-US:official&prmd=ivns

tulalhyt,
Do you mean that you have a 'converted' HTC Incredible now?
Which network are you using it on? CDMA or GSM?

spence341,
I googled 'gold card' like you suggested & I don't know what it has to do with this?
Here's an excerpt from an online resource:
What is a Gold Card ?
A Gold card is a special SD card which when inserted into your device allows you to flash RUU files with a different CID to your own device. For example if you have a AT&T branded device it will allow you to flash a generic ROM. ​As for formatting a SIM card to be used on overseas CDMA network, the Verizon HTC Incredible does not have a SIM card inside now so how can this work?
Or am I not understanding you correctly?
Thanks!
Konker
I am not sure, I came across a post by somebody in china that was creating a gold card to use the Inc in china. I don't know enough about it to give any advise.

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!

Dual sim and SD card simultaneously

I live in Europe and thinking about getting the G8s (we only have this version). Did anyone try to use the dual sim+sd card hack that you have on samsung phone? Cut a sim, polish it down and glue it to the bottom of an SD card. Then you can use two sims and and sd card simultaneously. One can also use a sim extender to achieve the same result.
Samsung implemented a software block on this since android pie, not sure if LG has the same.
Thanks in advance!
edit: it does work. Just tried on a phone.
Please post instructions so I may try this....
could you let me know how you got the DUAL SIM to work? what settings/software/app's you had to use? I'd like to make it work thru factory software if possible
THANKS,
MS

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?
