The GS3 Verizon is a CDMA device. Supposedly it has GSM compatible radios too. It's supposed to be able to work on GSM networks after a software update coming soon. Does this thing have a sim card slot? I don't see how it would work on GSM networks without it. Does anyone know how this works?
I'm hoping to use it on Verizon in USA, but on Telcel while in Mexico BUT with my Telcel sim. I realize my hopes are slim but if there's a sim card slot maybe it's possible???
Thanks.

It has a SIM card slot for the LTE. Unsure about compatibility though.

Actually, I have an old Verizon Motorola Z6c World Phone here that I bought in 2008. It has a Verizon sim card inside.
Z6c Specs say:
2G Network GSM 900 / 1800
3G Network CDMA 1xEVDO (800 / 1900 MHz)
Anyway, there's no LTE involved on the Z6c back then. SO apparently the GS3 will need the sim on non CDMA networks. I just wonder if the software experts here can make it possible to use the sim only at certain times and at the same time unlock the phone.
A lot to ask but will be a huge feature if done.

I said earlier that I wasn't sure about compatibility, but I'm starting to believe that this is not possible, as the Verizon version lacks the proper GSM/HSPA+ radios. There's a model comparison chart that you can expand on the Wikipedia page. Software probably won't be able to pull the miracle you're asking for. Sorry

Maybe this will help? http://androidcommunity.com/verizon-may-enable-global-roaming-on-lte-phones-soon-20120518/ from what I gather LTE is based off of GSM and its just a matter of unlocking the GSM bands on the phones.

Yeah, I don't think the current specs out on the GS3 are totally complete. If the phone is admittedly needing a software update to allow the GSM roaming then they can't just put those bands in the specs with no caveats.
After owning a dual-sim Moto G2, I knew I wanted a G3 with dual sims and 2GB RAM (16GB ROM). Unfortunately this isn't available in the UK so I bought one from eBay which came from a seller in India.
I don't NEED 4G as I have a mobile hotspot which works very well, but I don't take this everywhere with me. Is it possible to flash the modem or something to get 4G in the UK using this model?
Thanks,
Marc

This isn't just a modem thing, flashing a different modem will not enable the missing bands, that "feature" is buried deep in a secure partition of the device... And since there isn't a dual SIM 4G 16GB model in your country, until someone figures out how to unlock all the LTE bands in the device, there is no way to enable this at this time.

Thanks, I thought it was a long shot. I wasn't sure of the correct terms but I've just searched for "unlock lte bands" and it seems to have been done for some models, fingers crossed someone figures it out for the G3!

Really?!? Wow maybe I can get this working then. A Wikipedia page (I can't post links just yet) says that India has 2300MHz (band 40) 4G frequency, whereas UK has 800, 1800 and 2600MHz according to a PC Advisor link which I also can't post
I'm on O2 (both sims - I know, a bit daft but that's what I've got) and I've confirmed 4G is enabled on both sims. I guess the frequency that India don't use, is the 800MHz one that O2 uses, yes? Sods law if so. But I'll be porting my number to another network ASAP if that is right..
Thanks
Good morning xda community,
I just purchased a brand new Z3 (D6603) in addition to my existing Z3C. Before I purchased the device I researched that it has the proper basebands for AT&T. Based on xda, Sony, and various other online sources, the D6603 should support the following bands:
LTE Bands 1, 2, 3, 4, 5, 7, 8, 13, 17, 20; UMTS HSPA+ 850 (Band V), 900 (Band VIII), 1700 (Band IV), 1900 (Band II), 2100 (Band I) MHz; GSM GPRS/EDGE 850, 900, 1800, 1900 MHz
When I received the phone, I immediately proceeded to root it and update it to 5.1.1. Once I did that, I proceeded to obtain a nano-sim to fit the device. Once I put the nano-sim in I got "no service" whatsoever. The phone doesn't want to connect to AT&T. To test whether or not the nano-sim is defective, I proceeded to take the nano-sim from my Z3C, which is known to be working. Again, "no service" on the Z3. Then I put the new nano-sim in my Z3C and it did work.
In addition, I rebooted the phone numerous times, toggled airplane mode multiple time and also went back to KitKat to ensure it is not a Lollipop issue. All of this did not help.
Following that I proceeded to check the service menu (*#*#7378423#*#*). The phone states it is a D6603 unit. So does the original Sony packaging. However, when I looked at the available (working) basebands in the service menu I couldn't believe what I was seeing:
GSM_850, GSM_900, GSM_1800, GSM_1900, UMTS_BC1, UMTS_BC5, UMTS_BC6, UMTS_BC19, LTE_BC1, LTE_BC3, LTE_BC19, LTE_BC1
Obviously several LTE basebands are missing when compared to the original specs - some of which I need to connect to AT&T LTE. That said, I also switched the band preference to GSM only and couldn't connect either. Again, the nano-sim is confirmed functioning.
Any idea what this is? Did Sony change the D6603 specs? Any chance I can get to the full baseband spectrum as per the original specs? Right not it is basically a $350 paperweight for me.
In case you suspect the firmware's I used to flash / root / update and subsequently downgrade, I used the following:
D6603_23.0.A.2.93 from here: http://forum.xda-developers.com/z3/general/guide-rootrecovery-how-to-root-install-t3017056
D6603_23.4.A.1.232_Customized_US_SuperSU_XZDR2.8.2 1 from here http://forum.xda-developers.com/z3/general/d6603-5-0-2-flashable-stock-23-1-0-690-t3056361
When flashing, I used FlashTool without any exclusions (meaning that I also flashed the baseband). Full data, Dalvik and Cache wipe was also always performed.
I searched via google as well as here on XDA, but I couldn't find any post which appears to have the same problem. Again, any help would be greatly appreciated. I just want the basebands that the phone was / is advertised with. Thanks in advance!
-Oban
Also, in the Info menu (*#*#4636#*#*), when selecting the band / region, I only get "Japan band" as a selection. This would further indicate that something is off here.
Again, any help is greatly appreciated!

Hi Oban,
Try turning off LTE and see if that helps.
There is some issue with AT&T's HD Voice which works on LTE causing issues
http://forum.xda-developers.com/att...ming-calls-lte-mode-m8-att-arhd-34-0-t3026710
Also, where do you see the list of bands in service menu. I couldn't find it
@aviralmsharma, thank you for your response. Turning LTE off doesn't do anything to change the situation. I tried LTE only, GSM only and every combo in between.
The list of available basebands is in the service menu *#*#7378423#*#* -> Service Info -> Configuration.
As for the "Japan band", that is in the info menu *#*#4636#*#* -> Phone Information -> upper right corner where the three "..." are -> Select radio band.

Lol, the ROM I'm using somehow managed to not show anything
Working Band/s: Unknown error
.
Attached is how it looks for me. Sorry for the bad quality, but i had to take a picture of the phone with my Z3C. And i am currently somewhere over the U.S. In an airplane, so upload is painfully slow.
Any idea how we can fix my D6603?

You're right, I do see more bands. Could that be because of the ROM you're running and/or radio?
Attached is screenshot from my phone. Installed a different ROM
.
Aviralmsharma, i honestly don't know. That isnwhy i posted the question here at xda to begin with.
As you can see from my original post, i used the firmwares that are commonly available here at xda and have been used by many people before. I even used the U.S. Generic firmware version when i updated to 5.1.1.
Obviously something isn't right with my D6603. What should I do? I fear flashing the baseband in FlashTool isn't going to fix it. Is there a way to flash or enable the radio so it reads the proper bands?

The APN setting are correct and set for AT&T. I compared it to my Z3C, which is also on AT&T, as well as to AT&T's APN information available through their website. I still believe the issue is related to the fact that my D6603 does not list LTE band 2, 4, 5, and 17 as working bands - all of which are AT&T's LTE bands.
Any other suggestions that might work?
More suggestions
There is another thread that I cannot find right now that details how to unlock bands on our phones. I believe it originated in the Samsung threads but I am often wrong
Found it
http://forum.xda-developers.com/member.php?u=4300205
@Oban I believe that you do not have a international D6603. You seem to have purchased one of the Japanese models hence the missing bands and the Japan radio band selection. I suggest you try to return the phone to the place of purchase.

Kansasboy, wow... so Sony created a sub-version of the D6603 (carrying no specifically different model number) which differs from the international (or what I would call standard) D6603 model?
Is this "Japanese model" the same, hardware-wise, as the international model? Meaning, are the basebands excluded because of hardware limitations, or is it the software? If it is the latter, can the software be modified (as suggested in other threads - enabling bands on Qualcomm radios)? Or is the only way to return it as per your original suggestion?

Based on the bands you have, your phone is the SO-01G model for docomo mobile in Japan that has been flashed with the D6603 firmware, hence the D6603 model. The S0-01G has 32gb of storage which you would find by flashing the S0-01G firmware. I can not guarantee you that the bands you are missing could be enabled. It depends if Sony simply disabled the bands in the modem or if the phone actually has a different radio filter than the D6603. I have successfully unlocked lte band 12 on my D6603 and will be more than happy to walk you through the steps in unlocking bands. However if I were you I would simply return the phone and get a real D6603

So... I did spend some time playing with the bands and working through the qualcomm band enabling thread on xda. I managed to enable everything needed and now the working bands read as follows:
GSM_850, GSM_900, GSM_1800, GSM_1900, UMTS_BC1, UMTS_BC2, UMTS_BC4, UMTS_BC5, UMTS_BC6, UMTS_BC8,, UMTS_BC19, LTE_BC1, LTE_BC2, LTE_BC3, LTE_BC4, LTE_BC5, LTE_BC7, LTE_BC8, LTE_BC13, LTE_BC17, LTE_BC20
I also went into the *#*#INFO#*#* menu and enabled "USA Band" (previously I only had the Japan Band option). I also toggled airplane mode multiple times and rebooted the device more than once.
Now the bad news: still no service. I recognizes the sim card, but it doesn't connect / register with the network. I also triple checked the APN setting.
Before flashing it again back to stock: any last suggestion / trick I should attempt?

Am I missing something?
And one more comment: I did all the above on the 23.0.A.2.93 Generic Canada firmware (I couldn't find a US Version, and I wanted to try something beside the Generic Global).
Would it be worth it to try all of the above modifications on the SO-01G-specific firmware?

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.
https://www.youtube.com/watch?v=WIWbn8ecKwA
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?

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.

Hi All,
The issue with my Verizon M8 [the rare LRA (LTE for Rural America) subvariant] is that no matter what firmware version/RUU I use, I only get GSM connectivity on it. No WCDMA or LTE. I have checked the WCDMA bands in my country and that is not an issue. When I select WCDMA only option, I cannot get any signal. I have flashed the all the LRA (*.**.512.*) RUUs as well as all the Verizon (*.**.605.*) RUUs but no luck at all. If this issue might be related to PRL settings then please let me know if any of you have any idea. I have also checked the relevant WCDMA/LTE bands via CDMA tool and they are also enabled.
My M8 is currently S-off and has Super CID. I am using it outside the US on GSM network.
This has got me very frustrating and I need to find out if this is a software issue or a hardware issue. One more thing is that another guy here has exactly the same variant as mine. He bricked his radio by flashing the GSM firmware. I provided him my phone's relevant partition dumps and after flashing those onto his phone, his phone's radio became operational but now he has the same issue as mine. So I think that this issue might not be hardware related.
Any help on this will be greatly appreciated!!
Same problem
Anyone can provide any help on this??
any1 please help??

do you know the actual bands/frequency the gsm network uses where you are? the prl is going to be pulled from your sim card. have you also tried a diff sim card?

Hello. Yes, I know the bands used by 2G, 3G and 4G in my country. And yes I have switched sim cards even from different networks. The PRL version shows as 00000 when i look at it from the settings. I have even tried to update the PRL from a prl file provided by a xda user in some other thread but still it shows as 00000. I have seen some threads and ppl had this problem with One S. Though some of them were able to correct it by flashing some stock and custom radios.

odd. i wonder if that lra model is sim locked like the sprint variant. is it also acknowledging you have a sim card inserted when you check in about phone? as in, does it display the sim #

Well, I thought too that it might be sim locked but then why it is working with 2G networks. There should be no signal at all then. Also these LRA variants are being sold by many online retailers including Amazon as sim unlocked phones. And yes it acknowledges when I insert or change a sim. Says "Preparing sim card" and then I get a signal (2G only). When I choose 3G only in network settings, the signal is gone immediately and I have to switch back to auto or 2G only to get the signal back.

So then list the specific band numbers for 2G, 3G, and LTE for your carrier. That is really what the previous response was asking.

900/1800MHz for 2G
2100MHz for 3G
850/1800MHz for 4G/LTE

This is strange, as the 3G band 2100 Mhz is really common (many countries use it for 3G, and most any recent US phone intended for foreign travel will support it), and should be supported by the device out-of-the-box. This tells me the problem is likely not RUU/firmware related.
You sure the APN is properly typed? And does your carrier use any different APN for 3G, LTE, etc.?

No it uses the same APN for all types and its configured correctly. I also thought the issue might rather be related to some NV values or PRL. If I set it to 3G only, it "Sees" the carrier as I can see a signal bar in network signal guru app, but the mobile is not able to connect to it.
so i am thinking that since this is a lra variant, a lot of bands may be disabled. have you seen anywhere else that someone got a lra variant to work outside the us? i know you said people were selling it as being unlocked, but maybe its not

Well the LRA variant is practically the Verizon one with everything same as the Verizon variant. There a lot of links on both Amazon and eBay in which its mentioned that its LRA variant and is factory unlocked and can be used anywhere in the world. And yes I came across various threads on XDA in which people had this same variant, working fine (3G atleast) but they wanted to upgrade to Android 6 MM as there is no official update available for this variant after Android 5 Lollipop. As for the relevant bands (2100MHz for 3G used in my country), they were already unlocked (checked via CDMA Tool and QXDM).

hmm this is quite the problem. if you can confirm you are using the same rom as the others, i would then think the issue is the radio being defective

I am using the stock LRA RUU (android 5.0.2). I have also tried the VZW RUUs from 4.4 to 6.0 but the same issue exists on them all. Even I have used GPE and Sense based custom roms but the same issue. I think that the issue might be related to some NV values or this phone might be network locked. Is there a way to check if the phone is network/sim locked? As I am getting the (2G) signals for all the networks in my country.

it being sim/network locked makes sense, because the phone was made for people who live in the middle of nowhere. there would also be a high probability that none of those people will ever travel outside the country. i do not know anything about the nv values and tweaking them, but i have looked at that thread a few times. lastly, if you have only picked up 2g regardless of sim or apn used, it could be defective radios
