Unlocked and unbloated on ATT? - G4 Q&A, Help & Troubleshooting

I want to buy the G4 to use on ATT.
Is it possible to buy a model that is unlocked and unbloated to use on ATT? It must work with the LTE bands. Does the international version work?
If ATT introduces WiFi calling as promised this year, will I not benefit if not using the ATT model? How is WiFi calling supposed to work?

The International model will work and supports all AT&T bands, minus one, Band 30. Band 30 is the newest one and is supposed to go live this summer.
I don't think WiFi calling will work but I'm not positive on that.

Galaxy nexus and AT&T?

If we buy the Verizon version, unlocked, will it work on AT&T? Is this going to be an option, or just importing it from uk etc?
Could of swore i read somewhere that att's lte will work on a slightly different mhz that it won't be compatible with verizon's lte, someone correct me if im wrong.

The "AT&T" one, which at the moment is the same as the "world" version will NOT work on VZW.
As of now there are 2 models of the Galaxy Nexus: 1) CDMA/LTE (for Verizon in the USA) and 2) GSM/HSPA+ (for the rest of the world, yes including AT&T and T-mo in the USA).
As of now, there are no GSM/LTE versions (I'm assuming this is what you're looking for on AT&T). If you use the GN on AT&T, it will have HSPA+, but not LTE. And no, the VZW version will not be able to be unlocked and used with an AT&T LTE SIM card, because AT&T is only operating data on LTE, and you'd get no voice/text (assuming you somehow got the device unlocked to accept the SIM in the first place).
Unless Samsung/Google have some kinda curveball lined up to announce a 3rd model with GSM/LTE for AT&T, that will come in the future. As of now we're not aware of this model.

You are correct in saying the Verizon Galaxy Nexus will not work with an AT&T SIM. However, the reason you provided is incorrect. Currently, both AT&T and Verizon operate data only LTE networks. Neither provide LTE voice (Voice Over LTE aka VoLTE) but both plan to (Verizon in 2012 and AT&T in 2013). Whether or not the Galaxy Nexus can take advantage of VoLTE is another open question but it will be able to use CDMA voice either way.
The real reason your Galaxy Nexus will not work on the AT&T network is the LTE frequency bands are different as well as the obvious 2G and 3G CDMA/GSM incompatibilities. A Verizon Galaxy Nexus with the an AT&T SIM (assuming you can unlock the device) will never be able to find the AT&T network. Hopefully, future devices will offer software programmable radios that can be unlocked to interoperate on multiple bands. There are plans for some 43 LTE bands worldwide!!!
So I'm guessing that by the same token in Canada, if your with bell, getting the LTE version is pointless?

Thanks for a little more information, but I said just as much. Even if you somehow got it unlocked to accept a different LTE SIM card (don't think it'd ever happen), there are several reasons why the phone wouldn't work. Even if they did have the same LTE frequencies exactly (or you hacked it on), he wouldn't get any GSM functionality out of the VZW device.
Basically what I was trying to express is that the other things could theoretically be overcome with software/firmware hacks (VZW and ATT will operate in the same spectrum, just slightly different frequencies), whereas you can't ever overcome the fact that the CDMA does you no good on the AT&T network.
Overall I think the point has been made regardless...
dont forget sprint and other cdma carriers in US

Verizon Note 2 Vs. T-Mobile Note 2

Which Note 2 supports more networks and frequencies; and therefore, which would be more suitable for international travel. Is the Verizon Note 2 even pentaband?
T mobile version because it's gsm which is going to work overseas. Verizon is a CDMA and I haven't read that it has gsm support.

Yup, the T-Mobile version will work in more places overseas -- Especially Europe. Just in case, you might want to ask this in the Verizon area also just to make sure. :good:
I'm confused because on Samsungs website, http://www.samsung.com/us/mobile/cell-phones/SCH-I605TSAVZW-specs
the Verizon Model has the GSM frequencies,
is it GSM if unlocked; i believe the Note 2 is already unlocked by verizon, will it work on GSM frequencies internationally?
correct me if I'm wrong, thanks
the verizon Galaxy Note II apparently has the GSM radios,
also has LTE; doesn't AT&T LTE work along same frequencies as verizon LTE
or is the verizon LTE exlusively to CDMA?
All Galaxy Note 2 devices seem to have all WCDMA, GSM, and LTE bands.
But what I understand is that Verizon version is considered as a "world" phone. I know that they tell me that I can use their Galaxy Note 2 on the European Networks.
I have played around with the bands on my T-Mobile Galaxy Note 2 and can get the WCDMA and LTE working. So I don't know if the Modem firmware in all Galaxy Note 2 are the same and just need to be activated by the carrier's sim card or not. Someone please educate us on the this. I know that their is talk of needing OTA update to activate the LTE within T-Mobile GN2. But if the Modem is all the same then can just updating or exchanging the sim card could do the same? Or does the nv file also needs to be updated to activate the band/s as well?
The question is not if Galaxy Note 2 (all verisons) have the bands. But how to (the actual process) activate the band, in question, and get the Galaxy Note 2 in working order with the carrier of choice? What is the method? How to do the process of this method?
Please correct me if I am getting this wrong.
^ good point, and also just to ask about the verizon note 2 again, i thought it carries carries an an additional radio for CDMA, does this mean that the verizon note 2 model has better capabilities worldwide' since it is virtually compatible with all networks in the world (simply tweaks to the frequencies to the radio can get the verizon variant working virtually anywhere) please correct me if I'm wrong here. thanks

Problem I have seen in the past with Verizon world phones is that the game frequencies only work overseas. And lte is gsm band. Which is one of the few reasons Verizon phones have a sim slot to begin with

All recent Verizon LTE phones have GSM radios built in as well as their own CDMA/LTE radio. The LTE radio is only compatible with their network.
Some of these phones are even shipped out of the box unlocked and can be used immediately on GSM networks in the U.S.
If you do get the Verizon Note II and want to use it on T-Mobile, it will not have support for their HSPA+ 42mbps network, I believe it maxes out at 21mbps, as with all other Note II's around the world except for T-Mobiles.
But doesn't Verizon use LTE on the 700 band just like AT&T and future TMobile LTE?

Please correct me if I'm wrong, thank you.

So the Verizon Note2 is like the AT&T Note2 & Sprint Note2 (supporting 21Mbps HSPA+ but not 42Mbps like T-Mobile) but all only with their own respective LTE?..wouldn't it be more cost effective for Samsung just to make 1 phone with all the hardware to support all (isn't the iPhone5 like that now?) or is it cost prohibitive or do carriers not want to make it easier to unlock?
Are we still confident that the T-Mobile Note2 is the best if we want the flexibility to use on all carriers? How often is >21Mbps HSPA+ seen in real world use & why is the disabled LTE not listed at http://forum.xda-developers.com/forumdisplay.php?f=1877 ?
So, which is better then, Verizon or T-Mobile? Verizon's Note 2 also includes a CDMA radio whereas the T-Mobile version does not. If you are using the Note 2 in the US, wouldn't you have more flexible options in terms of which carrier to use?

So do we consider the Verizon Note2 even more carrier flexible than T-Mobile's Note2 (as I was about ready to buy the T-Mobile Note2 to try their $30/mo plan but now having some doubts..if I want this tomorrow I need to order soon) ?
-Thnx
Well LTE On the Verizon Note 2 is only compatible with Verizon's Network. Even if unlocked; the phone's firmware only recognizes LTE if only the Verizon 750 band is detected. Verizon has its own exclusive LTE bands compared to AT&T and Future T-Mobile LTE (sharing the same LTE bands)

I cannot speak to the CDMA radio issue, but I am positive that Verizon LTE will not work with any GSM LTE phone. The frequencies are similar, but Verizon is using a different LTE protocol. I asked that question a long time ago, thinking that LTE would finally allow roaming between Verizon and AT&T, but they are too clever to allow such a democratic system to function. They will remain fundamentally incompatible, not because they need to be, but because they want it that way to keep you locked to your carrier by your choice of device. Nice, eh?

The Verizon NoteII will (in theory) connect to any gsm carrier. How to do so, I don't know.

^^^ Well, the Verizon Note 2 will not be able to work with another carrier's LTE than itself.
my experience
Hey folks,
I've got the Verizon Note 2 and I love it. If you're willing to unlock the bootloader and then install a hack onto your device, you'll easily be able to swap the SIM card out and use it just about anywhere. Yes, the phone is carrier unlocked (not the same as bootloader unlocked). The issue is that in the settings, they won't let you add the specific APNs for the carriers you need. I"m not sure how else to get around that without installing some of the hacks. I managed to do it and it works beautifully on Canada's Bell Mobility, HSPA+ is screamingly fast and the LTE on VErizon in the States is just insanely fast. My recommendation: get the Verizon version because they've built out their LTE much more than their rivals at this point.
On anantech the reviewer stated that the tmobile version would be the most compatible. If you get vzw note2 and switch you wont get lte on tmob or att. Quite frankly vzw is too expensive and the coverage from tmobile is getting better by the month. Not to mention their business pricing is better than any of the other carriers.

N7 Bands supported?

Hello,
I am a US customer of T-Mo, and I have a N7 pre-order in with them. However, the locked bootloader has me concerned. I definitely want to root, and would later want to run custom roms, TWRP, etc.
Could someone please definitively clarify if one of the International Note 7 models (even better if it is a Dual-Sim unit) will cover the LTE bands for T-Mo (and possibly the other US carriers) in one of the SIM slots? I am willing to buy the international version outright if I can still get full speeds while I am in the states and when I travel internationally.
Thanks!
-Rob
The 930F will cover all of the LTE bands for T-Mobile. I presume the FD does as well, but I don't have a source for its specs.
If it's anything like the international S7E, you won't get VoLTE or wifi calling.

International version work on vz?

Will the international version work properly on vzw? All bands?
I dont think it will work on verizon and sprint something with the chipset. thats why they went with snapdragon.
Thread cleaned.
Please be respectful at all times.
Yes it will work. The best way to check is to just try. I used an unlocked AT&T Variant S7 Edge on my Verizon, and it worked! Although AT&T uses GSM technology most 4G LTE bands overlap.

The at&t version is not the international version. The international version does not fully work for cellular calling on Verizon.

[Q] Best way to get a phone that will work with Verizon and all LTE bands overseas

I've really enjoyed my S7 and want to upgrade to the S9. Later in the year I'll be overseas for almost a year, so I want something that will work with all Verizon bands of LTE, but also not have a firmware lock that would cause it to not work on other bands of LTE overseas. (planning to just use prepaid dataplan sim cards overseas)
I think my two options are to either get a US 'unlocked' version or wait for the 'international' version. My understanding is the primary differences between the unlocked and international version is the 2G/3G coverage for CDMA and possibly slightly different hardware. I'd rather have a phone with CDMA backwards capability, but my prime concern lacking full access to all LTE bands available wherever I am.
I'm not really interested in going any route that would require me to root the phone if there is a way to do it without.
Well the only way to get VZW compatibility is the VZW phone or a US unlocked model. So you're looking at the US Unlocked model at this point.
A listing of all the different model numbers available (per country and carrier) is available here: https://www.techwalls.com/samsung-galaxy-s9-sm-g960-g965-model-number-differences/
You will probably want to get the phone that works with your primary location the most. I am not sure which countries use which frequencies for LTE in Europe; you will need to research that to see what you may be missing out on.
With my T-Mobile S7, I haven't had any issues when traveling in Europe or Asia. It connects to LTE usually.
So I just did a deep dive of that list:
It looks like the Verizon and Unlocked versions are almost identical (the unlocked US version has B46(5200) 4G TDD LTE, but I'm not sure anyone who uses it)
Looking at 4G FDD LTE it looks like a Verizon or US unlocked phone will have almost complete coverage around the world, notable gaps are B30(2300) in China/Canada/US AT&T, B32(1500) in UK and B71(600) (US Tmobile). I thought that was a bit confusing as you'd expect a US Unlocked phone to service all LTE bands available in the US yet it lacks AT&T and Tmobile bands.
So based on all that information looks like I should just get an unlocked US phone to be totally safe, and I'd likely also be fine getting a Verizon version also.

So I'm new to Android but i use Verizon prepaid. Will I lose anything by going with the unlocked version or should i stick with a Verizon S9?
I don't use video calling. All i do is text and talk but I've heard that people on Verizon prepaid have issues with unlocked Android phones.
Thanks
Would Wifi Calling work with the US unlocked on verizon? I thought that required a Verizon FW to be flashed. I imagine all the other features such as voLTE / HD calling, etc to work on the US unlocked.

I did a cursory review of the wifi-calling FAQ on their website. They don't mention anything about compatibility with Unlocked versions of phones (that I saw). I'd call tech support to ask, but I'd expect there to be a 50% chance of getting the wrong answer from the tech based on my interactions with their support.
There might be some good experience based anecdotes in the Galaxy S8 forum, if it works on an unlocked S8 its a safe bet it will work on an unlocked S9
I think I'll ask in the Verizon subreddit, it seems like they normally have really good information as well.
I'm mostly curious about the LTE TDD Band 46 (5200) - its the only band an unlocked US phone has that a Verizon phone doesn't. 5200 is in the U-NII frequency range, no cellphone service providers use it, but I wonder if it may be used for local LTE networks in the near future. The other advantage is avoiding all the verizon bloat wear, but that may be what allows the Wifi Calling to work!
All this has me thinking I might have to add the extra $80 and just buy the Verizon version. I don't get phones on contract and I've always just paid full price. (Page 2 404 error?)
Apparently the Nov/Dec Samsung s8 firmware update added an option for BYOD carrier provisioning for unlocked s8. Given the similarity, I'd imagine the same to be true for s9. Can someone who has an unlocked s8 confirm?
Well after a little more research I see that if you use Verizon prepaid you lose visual voicemail and WiFi calling even if you use a Verizon phone so there's no need in me paying extra for a Verizon S9. Unlocked it is.

You might wanna check this as Verizon is starting to implement network locks on some devices as to deter thefts more
Dont know when or what devices but it was a statement Verizon made
So, you're saying the prepaid SIM might not work in an unlocked S9?
I don't think Verizon is keeping Verizon prepaid SIMS from working in unlocked phones they are just locking their phones like Sprint and AT&T still do.
I had no problems with my unlocked Pixel 2 XL that I purchased from Google and my Verizon prepaid, just no visual voicemail.
