UPDATE: after two separate tweets from the U.S. T-mobile company official Twitter account stating (or implying) that LTE band 71 (600 MHz) would also be included in the "carrier unlocked" version of the LG V30, now the U.S. "T-mobile Help" (customer service) Twitter teams says they don't know. Please note this is a different department than those "T-mobile" Twitter team (management) who said yes.

But thanks to @Septfox for trying to pin down the answer, even if it's "we don't know".

Since the LTE band 71 has NOT shown up on US998 in FCC documentation, this probably means no. UNLESS:

1) LG submits a revised spec sheet to the FCC, which can be done. It would actually be in T-mobile's best interest for LG to enable that band on the "carrier unlocked" model. While T-mobile would not make money off hardware sales, they would gain additional customers who are considering switching. (Many people want a phone NOW, but need to get their ducks in a row family-wise to switch over to a new carrier.)

2) T-mobile radio can be flashed onto rooted "carrier unlocked" LG V30 US998. All the LG V30 hardware (antennas, etc) should be the same. At least from manufacturing efficiency it should be the same. Then it just depends on the firmware to enable specific bands.

ORIGINAL POST:

T-mobile LTE band 71 (600 MHz) will also be available on "carrier unlocked" LG V30, not just on T-mobile's LG V30

LG V30 US998 will have ALL the U.S. carrier bands, so you can take it to any carrier you wish -- even T-mobile. Otherwise it would be pointless to have a U.S. unlocked carrier version if there were any carrier bands it did not have.

This is also the LG V30 model number that will be eligible for REAL bootloader unlock, unlike the recent T-Mobile LG G6.

______

T-mobile has LTE band 71 on their newly implemented 600 MHz spectrum and the LG V30 is the first phone to use that band.

While LG also releases "carrier unlocked" versions of their flagship phones, which qualify for REAL bootloader unlock and thus root, TWRP, custom ROMS, etc., no spec websites have listed LTE band 71 (600 MHz) on the upcoming carrier unlocked LG V30 US998. (While not yet announced, we know the model number because B&H Photo has a placeholder page and it matches previous "carrier unlocked" model sequences. It's also the model given to reviewers during the pre-announcement embargo period back in August.)

So, people assume and even T-mobile customer service reps have stated that to get LTE band 71, you must buy the T-mobile variant of the LG V30.

For people who want dev work, this was disappointing, because while T-mobile previously was dev friendly with either unlocked bootloaders or easily unlocked bootloaders, this has changed in the past year. I could give multiple examples, but the most relevant is the recent LG G6... The T-mobile LG V6 bootloader is ostensibly able to be unlocked, but not really. LG/T-mobile removed all ADB flash commands except for bootloader unlock.

Like having the keys to the car, but there's no car. In effect, the phone is still locked down. So, months later still NO root, no TWRP, nothing can be done.

Six months later, there's still no root (even with a 22 page root bounty thread), no usable TWRP and no usuable ROMs. Yes, some devs have ported ROMS for the T-mobile LG G6, but no one can use them. Meanwhile the UNLOCKED LG G6 phones have tons of dev work, because they qualify for REAL bootloader unlock.

A second subset of stakeholders are people who are considering switching to T-mobile (or T-mobile affiliated MVNOs) in the future. They would have to buy T-mobile LG V30 now to be future proof, as T-mobile will roll out more of this 600 MHz spectrum in coming years. The "carrier unlocked" model (which can be taken to ANY carrier) would not work for them, if it didn't have LTE band 71...

Then, yesterday, from the official T-mobile Twitter account, T-mobile stated that to get full 600 MHz experience, you could buy their LG V30 OR buy the unlocked version direct from LG.



Well, the unlocked version is LG V30 US998. And yes, while you can buy unlocked versions straight from LG if it makes you feel better, you can also buy them online at B&H, Amazon, even eBay.



IF TRUE, this is great news for the dev community and for LG V30 users. This is also NEWS because no other websites are stating this. And if T-mobile is officially stating this through Twitter -- just like they have officially announced many other things, why wouldn't it be true?

I've contacted one spec website for them to correct their now outdated information, and sent it to XDA News as it's big news.

I must be the only person reading that Twitter quote as buyers having the option of purchasing either 1) from tmobile to get 600mhz support or 2) from lg to get the unlocked phone ( but no 600mhz support). This from the sentence structure. I hope I am wrong.

I'm glad I'm not the only one who read it like this, thought I was just being paranoid :v

I did send them a tweet myself, but because I'm an idiot and tired, I didn't word it so that the "yes" replay was explicitly for the unlocked variant.
https://twitter.com/Xoftpes/status/907867685613998081

Someone else tweet'em, ask if the unlocked, non-carrier variant will have 600mhz support without having to mess with it. Just that, don't mention the T-Mobile variant at all. I'm going to bed : |

Still, this seemingly twice via Twitter they've stated/implied the unlocked carrier version of the LG V30 will also have 600 MHz LTE band 71. IF they are NOT saying that, it's very misleading. Yeah, I also parsed the original tweet, but decided it made more sense to take it at face value... Why would you have a carrier unlocked phone if it didn't have all the carrier bands? I may be wrong, and if so, I'll be the first to update the the first post.

NOTE: Please, NO ONE quote any online or phone T-mobile customer service reps. Those people don't really know about stuff like this. Yes, even at the "highest levels". And I mean that in the nicest way. I don't know how many times I have seen transcripts posted here on XDA "proving" something from from various customer service "chats" (escalated to the "highest level") -- which of course were totally wrong.

One example specifically was Samsung online customer service reps saying the Galaxy S8/S8+ Snapdragon U.S. "carrier unlocked" version would also have bootloader unlock? We KNEW that was wrong, even before the phone was released.

"But I have the transcripts!" Doesn't prove a thing.

At least Twitter posts from company account are considered official company statements.
And I happily accept those as proof. Even the president of T-mobile re-tweets the company's Twitter posts.

If anyone wants to have another crack at pinning down the language, please do so. But again, only from trusted sources! Please, NO online carrier customer service reps!


From another thread, where we're discussing the same topic:

In other news, apparently the 128gb variant isn't going to be that much more expensive, something like $50...but I can't remember where I saw that.

I have no explanation for the FCC findings unless there's going to be a "revised" submission or something before the US998 model is officially announced.

Other related questions are whether the unlocked V30 will support volte and/or wifi calling.

Based on the info in this link, it appears that unlocked LG devices do not have a good track record of supporting these features. I hope that changes with the V30.

That would be my guess, yea. Someone over on reddit has suggested that if what T-Mobile says is true, it might mean that LG has/is going to file a class 2 permissive change so they don't have to go through all the hoops again.

I read somewhere earlier that someone successfully used VoLTE on Verizon using an unlocked g6, no screwing around needed. No wifi calling, though.

The g6 is probably the closest thing to an actual predecessor for the v30, and as far as I've seen Verizon sets the bar highest for "how much of a pain in the ass do we want to make it for non-native-variant phones to use our features". So I would expect carrier-agnostic VoLTE/HD Voice/etc at the least, and extras like wifi calling requiring some custom tweaking to get working.

At this point in smartphone history, the V30 (i.e. US Unlocked) not having wifi calling would be epically stupid. I find it hard to fathom LG would not include wifi calling on this device but then again some of these companies have a history of omitting "no-brainers" .
I'm not fond of 18:9 but will accept it. If on top of that LG leaves out wifi calling it would give me pause...
I'm with mintsim (tmo) so 600 mhz is great but wouldn't a deal breaker.

Great question! You would need to purchase the T-Mobile LG V30 when it comes out in order to take advantage of our Band 71. *RickK

I am a new user so I cannot link directly to this but feel free to look it up. Maybe RickK doesn't know what he is talking about, right??

The problem is, wifi calling requires support from the carrier end, probably their special app, and maybe even some special RIL and framework stuff depending on the carrier. You're on a phone that you went out of your way to not buy from them, so they're not exactly inclined to provide any of that for inclusion in the OEM's ROM.

And that's the impression I get of using unlocked phones here in the US: technically you can go to any carrier you want, but getting features beyond voice and data working pretty much depends on whether or not they decided to make things easy and use AOSP implementations (like what looks to be the case with VoLTE), or an enterprising dev manages to spackle something workable together.

... or maybe I'm full of crap, who knows. I'm on Tracfone, MVNOs don't get all this fancy stuff :v

Considering the ambiguity of the other tweets, and the FCC entry lacking b71, it wouldn't surprise me at all if he were right.

Sure would be great if LG would respond on Twitter. I know it's an unreleased product, but come on. I really don't see the issue with providing potential customers a bit of basic information that could make or break their decision to purchase said product.

Pointing out again that, regardless of official support, it's not terribly unlikely that the hardware is the same, making enabling b71 manually a possibility. We should get one of the review unit people to try screwing with service menu settings, to start.

(double post because editing isn't working right)

Can't sleep, going at this again.

Between canned responses and conflicting tweets, I'm getting the impression that T-mobile doesn't actually have the information.

Finally. As I suspected, T-Mobile (or at least, their Twitter team) doesn't actually know.

And it makes sense that they wouldn't; T-Mobile quite frankly doesn't need to know anything about the unlocked variant, and it's not as if LG is particularly keen on volunteering information at the moment.
They're concerned about their own variant having support, and rightfully so considering it's the first and currently only phone that does (on a somewhat related note: FCC filing says that the Pixel XL2 doesn't have it).

If it's not already in the works, I would expect LG to file a C2PC after people start complaining that their unlocked phone has an incomplete set of important bands, and failing that...aforementioned other options.

I told you we would laugh at any online support rep transcripts. The NEVER know stuff like this or give completely the wrong answer.
