Hi all,
There does not seem to be any resource that clearly shows the variations of the U Ultra at present.
I personally have a TW market model, with dual SIM. It appears that the bands on this model are not right for North America (and perhaps also South America) but are fine for my uses in APAC.
Given that there is limited info, perhaps we should gather some information.
Mine: 1.09.709.7 Taiwan model, Dual SIM
I am located in Australia, and Australia launches on March 8. It is unclear to me which model, though the product page on HTC's AU site suggest it would be single sim.
Can others who have gotten an U Ultra in other markets comment on their version? UK / India / NA?
Reason why I've put this in this subforum is so that we can explore the possibilities of opening up hidden bands with different radios (I believe my Taiwan Model supports: FDD: B1/B3/B5/B7/B8/B20/B28 TDD: B38/B39/B40/B41) and the AU model lists FDD: Bands B1/B2/B3/B4/B5/B7/B8/B12/B17/B20/B28TDD: Bands B38/B39/B40/B41 - which is in line with US?
Also, it may allow single sim to potentially support dual sim? as the dual sim has a combo slot with microsd, perhaps the hardware is there for single sim to support a second sim.
Lets explore what we can do with this phone!
Hi, seems like you posted on the wrong section. Maybe a moderator could move it to "HTC U ULTRA GUIDES, NEWS, & DISCUSSION" ?

Hey Wolf, you're probably right, a mod prob should move this. I originally intended this to form a basis where we can collect all the different firmware / radios etc, as I was under the impression that there were multiple hardware variations worldwide....
In one of the threads here on XDA, another member suggested he ordered the intl. model and it didnt support the right bands for the USA. Leading me to think there were multiple models.
I'm starting to think there isn't, here is why.
1. Michael Fisher (I think he's in Canada) imported a TW market phone for his early review. It appears to have LTE in the film, and he doesnt mention anything about incompatibilities.

2. Jeff Springer (I think he's in the USA) imported a HK market phone, it also appears to have LTE - https://www.youtube.com/watch?v=fclOYUyfxnE&t=522s
I believe the belief that the intl. model doesnt support USA bands (2/4, etc) comes from the practice (poor practice, admittedly) for HTC's Taiwanese website to only declare the bands that it perceives are relevant to Taiwanese users. The HK website suggests the same as taiwan = FDD: B1/B3/B5/B7/B8/B20/B28 TDD: B38/B39/B40/B41
The UK / India / USA / AU sites all state - FDD: Bands B1/B2/B3/B4/B5/B7/B8/B12/B17/B20/B28TDD: Bands B38/B39/B40/B41
With USA & AU not stating support for dual sim, but HK, TW, India, UK do.
I believe there is only one model (with multiple software variations), and the information published being variable.

HTC U Ultra through Vodafone Australia does not support dual sim out of the box. The example I saw today was running 1.09.710.12
I purchased one off of an eBay from a Chinese vendor; I'm pretty sure it's the international version since it has the dual sim and int'l charger. I can confirm no problems here in NY and I'm on T-Mobile.

That's pretty good news.
Can you confirm the model number of yours (On box, printed on the back of the handset in feint print) - I'm assuming this is a "U-1u"
If you can also let us know the version number of your firmware - Settings, About, and then Software Info. If you got an Intl' charger it might be China or Hong Kong stock (Taiwan uses the same plugs as US).
So the Hong Kong (and Taiwan) version states: FDD：B1/B3/B5/B7/B8/B20/B28 TDD：B38/B39/B40/B41, and T-Mo in the USA uses B2 / B4 and B12. So its obvious that the support does exist, just simply not denoted appropriately on the website.
Great news.
Question - are those phones, that are/are not Dual SIM supporters, different in Hardware or just software manipulated limitations? I am asking this as my phones doe not recognize second SIM, but if I were to flash it with unlocked software for dual SIM, would it work? Thank you!

I'm not sure about that, but I tried 2 ROMs which supported dual SIM, and those weren't able to use the 2nd SIM/sd slot.. not sure about any customizations inside the rom/kernel/whatever though
OK I understand that, still, I am wondering if there are actual hardware limitations for the dual sim or just software, never mind the ROM...
I have buy my phone yesterday and it is a Single SIM phone for EU market (Made In Taiwan) and with productID number finishing with ...100. Dual SIM phones ID finishing with ...200.
I put my sim card to second (mSD/nSIM) slot and i when i turn on phone i have 2 sim cards drawed onphone (one empty and another (absent sim) with a full signal but crossed mark...
Hmmm, sims like have second SIM card software blocked ?
The same thing is happening on my Single SIM (EU) phone. If I insert the second SIM into the 2nd SIM slot, the phone recognizes it and displays a full signal bar with a crossed mark. Obviously, the hardware is capable of handling the second SIM (otherwise it would not be detected at all), but it's crippled in software. So far I did not find a way to unlock Dual SIM support.
Did anyone of you guys try flashing a rom with dual SIM support?
Hi i found main difference between Single Sim and Dual Sim HTC U Ultra :
NETWORK3
2G/2.5G GSM/GPRS/EDGE
Single SIM
850/900/1800/1900 MHz
Dual SIM
850/900/1800/1900 MHz
3G UMTS
Single SIM
AWS/850/900/1900/2100 MHz
HSDPA 42, HSUPA 5.76
Dual SIM
850/900/1900/2100 MHz
HSDPA 42, HSUPA 5.76
4G LTE™ (up to 600Mbps)
Single SIM
FDD: Bands 1, 2, 3, 4, 5, 7, 8, 12, 17, 20, 28
TDD: Bands 38, 39, 40, 41 with 2CA, 3CA
Support Cat 11 LTE: downloads up to 600Mbps, uploads up to 50Mbps
VoLTE and WiFi calling
Dual SIM
FDD: Bands 1, 3, 5, 7, 8, 20, 28
TDD: Bands 38, 39, 40, 41 with 2CA, 3CA
Support Cat 11 LTE: downloads up to 600Mbps, uploads up to 50Mbps
VoLTE and WiFi calling
It appears that Single Sim is made to work with AWS. >>>>> AWS is used in the United States, Argentina, Canada, Colombia, Mexico, Chile, Paraguay, Peru, Ecuador and Uruguay.
and supports more bands then Dual sim one. I think flashing dual sim softwer version will change nothing since you still wont be able to use 2 sim cards.
I was mislead from some reviews, including gsmarena, that said HTC Ultra only had a dual sim version and I bought the phone. Unfortunately it doesn't support the 2nd sim. In my case it doesn't even have any icon crossed... I wonder why does it have the place holder for a second sim...
Anyone was successeful in accessing the 2nd sim on a single sim version? (model number ending in "100")
Actually I've also tried a bit to get dual SIM to work on my single SIM device, but flashing dual SIM activated ROMs wasn't enough and I've no idea what I could try now.
Maybe ask one of the ROM developer's?
Guys i dont think it is possible since as i posted above it is in some way different device. Same as you cant enable more bands support on dual sim version by software.

Anyone know if the 5g version is dual SIM... Two different people say two different things. If I pay to get a dual SIM tray from eBay...
Regards
The 5G version, which is currently only sold by EE, is not dual-SIM. It can be flashed to the dual-SIM international firmware but you lose the ability to use 5G by doing so. You would also need to replace the single-SIM tray with a dual-SIM tray.
The international firmware has no firmware, drivers, etc. to run the 5G X50 modem. Unfortunately, that is only contained within the 5G firmware.

Is this something that can possibly be fixed software-wise in the future?
I wanted to get the oneplus 5g but I needed dual sim as well (plus the relatively worse support as updates have not yet been seeded to Oneplus 5g unlike the non-5g versions) - sounds like EE and OnePlus bamboozled consumers with a more expensive but poorly-supported 5G version

You can restore the original firmware to restore 4G, but you will lose dual-SIM. However, you could try flashing just the OTA on the %G to see if it leaves the 5G enabled while enabling dual-SIM. I haven't seen anyone doing this specifically on the 5G model but flashing the International US OTA on the T-Mobile stock firmware leaves you with a T-Mobile dual-SIM hybrid.
Hi, how did you get on with this as I was considering the 5G, but like others didn't want to lose dual SIM?
I have ordered dual SIM tray to give it a go as was told by rep at OnePlus the 5g does support dual SIM it's set to single sim at ee request ?
Please update when you receive it.
I've made one of the SIMs to fit in the tray without buying a dual SIM tray and it's not dual SIM capable. So I think it's the EE firmware to be blamed for single SIM use....?

The activation of the dual SIM facility will be in the firmware. The 5G version has two modems the x50 for 5G and the soc 855 built in 4g modem. Until EE/ OnePlus releases this and the Wizards on xda find what's blocking the function,we are batting blind!

It was always indicated the the 5G version was single SIM.

The dual-SIM hardware is there. If you flash one of the international firmware versions, you will enable dual-SIM, but at the cost of losing 5G. You only have 5G with the 5G firmware, because that firmware is the only one that contains the X50 modem support.
what firmware will work on my op7 pro 5g as i want dual sim not bothered about 5g
Sorry to bump an old thread. But any idea what firmware I'd flash on the European (EE) variant in order to enable dual-sim?

Flashing the Global firmware would, but you will lose 5G. There is no dual-SIM 5G official firmware.

This is incorrect, there is no way to enable dual SIM on the GM1920 or GM1925. This would require a modem.img with the SDX50 dsds configs, which we don't have.
you can however the flash the European 10 update on to the Sprint model, there are issues with Sprint data, but non Sprint carriers work fine.

The only difference between the 5G and non-5G models is the add-on modem. All devices have the dual-SIM slot, just the SIM tray needs to be swapped if the firmware is changed. The global firmware does not have anything to run the 5G modem, meaning it won't work, but 4G will. Whether flashing the Global, EU, or another firmware, only changes the bands and carrier support. Clearly you didn't fully read my post before saying it is incorrect.

Clearly you dont own one and havent tried, or you'd know it doesn't work.
I have.
I'm well aware the hardware is there for dual sims, but we have not found a way to enable it, the non-5G firmware WILL NOT BOOT FULLY when flashed via dd and fastboot and we have no way of using an msm to see if the result is any different... I've worked closely with the "guac for all" devs on this matter...
If you're actually interested in knowing more or think you can get it to work somehow, pm me and id be happy to brainstorm with you.
But myself and a group of others havent been able to enable DSDS, it's not just as simple as you are implying it to be if it is possible at all.
I just heard it from one of the reviewers and I needed to confirm it from one of the experts here

Nope..you can just have 5g on one sim card available. Second sim can be still used for phone calls etc..
Hint: i am no expert...but common sense should apply

so you say when 5g is enabled, phone is only single sim? I thought one 4G + one 5G. Could you please try if SIM2 can work with 5G? or 5G has to be SIM1?

When 5g is enabled, phone is only single sim and sim1or2 doesn't really matter.
Yes poco said that when you use 5G phone will be single sim till they will give update that will make 1 sim 5G and other will be 4G
You just have to read the user guide.........
About Dual SIM:
• Supports Dual SIM cards with no carrier restrictions, single 5G or dual 4G
connectivity ①
• Supports Dual Nano-SIM card slots, either card can be set as the primary
card
• Supports single SIM 5G/4G+/4G/3G/2G
• Supports Dual SIM 4G+/4G/3G/2G
• Supports Dual SIM VoLTE HD calling ②
Note ①: 5G support depends on the local telecom operator’s network; if
the primary card 5G is enabled, the secondary card will not be available;
subsequent software upgrades will include support for primary 5G and
secondary 4G/3G/2G card mode function in dual-card situations.
Note ②: VoLTE service availability depends on the local telecom operator’s
network and service deployment
Not so complicate....
So according to the user manual dual sim support while 5g enabled is coming with a future update? the phone is five months old, did the promised update come through yet? are all other ROMs available for this device have the same issue?
The promised update is yet to come .

The phone was launched 5 months ago but probably due to the pandemic there is surprisingly little development and discussion from the community's side. Barely 4 roms.
I have been waiting 2 months now to upgrade because there is no way I ever use MIUI.
Last week LineageOS was released, but it's Android 10, and only initial build.
I will probably wait or lineageOS 18 before I buy this phone, but this means waiting few months the way things are going.
Dont forget that very few people use dual sim on their phone... Not a priority to fix ;o)

I am thinking to buy IN2013, is it possible to activate Band 71 for T-mobile use?
Or should I buy IN2017 and try to flash a ROM that will activate dual SIM? Dual Sim is a non-negotiable feature I need.
No.

No to both questions?
No, you can't add bands. And I know you've said you need dual sim, but I just don't think you'll get optimal network coverage unless you have the IN2015 or the T-Mobile variant ... which I think are only single sim.

I see. I was asking because a had bought a IN2013, but they sent an IN2017 instead. They apologized, but they also told me that if I flashed the global ROM the dual sim functionality would be activated since IN2013 nd IN2017 are the same hardware.
I ended up returning the phone, but I figured it could be a possibility if the vendor is correct about that.

They are you can flash it to the global firmware and get a dual SIM tray for it. The T-Mobile is the same as the unlocked variant here in America from what I understand. The only difference is updates, the SIM tray, and it's officially IP rated.
Hi, im currently in south africa, i have a Huawei p40 pro ELS-NX9. this is a dual sim version, however, i only have one nano sim slot, and the other sim is an eSim. my network provider usually takes the dual sim feature away. Is there any way i can enable sim slot 2, as we in south africa do not have eSim capabilities.

It seems to be an hybrid SIM device with only one physical (nano) SIM slot and an eSIM. Dual SIM feature is only possible by using one eSIM AFAIK
Can you please confirm that I can use eSIM and physical SIM at the same time on the P40 Pro making it a dual standby phone? Thanks.
if you look closely, the second sim, gets behind the first ... apart you have option to esim
