At&t + T-Mobile Merger Hurts Potential US G2x Buyers

Hi alls, I wish I had better news to bring. The good news is, as expected, the 2X runs stock Froyo.
Now the kicker: as you are all probably aware, At&t has gobbled up T-mobile. This means that when the transition is complete (expected a year to 18 months from now) At&t will drop T-Mobile's 3G bands to EDGE.
It may not affect some owners but for me, I usually keep a device until a big hardware refresh comes about- like a quad-core chip. I'm skipping the 2x for the Galaxy II or the Optimus 3D. I was on the verge of owning this...

Luckily the normal 2X do support UMTS 1900 (one of the 3G bands AT&T use), that's why I am consider buying it off contract from other place and use it on AT&T

Let me understand: do you mean the non-US version of the 2x, the off-contract US retail model, or both? Thanks!

It's been reported that the G2x will support T-Mo *and* AT&T bands:
http://www.anandtech.com/show/4231/lg-optimus-2x-coming-to-usa-as-tmobile-g2x-
UMTS/HSDPA/HSUPA Support 1700 / 2100 (AWS) / 1900 / 850 MHz
So you can rest assured that T&A-Mobile will support the bands on your phone right through to the bitter end of HSPA over AWS, right?

Ha! I was spying Engaget & Giz all afternoon yesterday & the announcement was made @ Anand...! Thanks for the heads up!

at&t hasn't officially bought T-Mobile yet -_-
An acquisition of this magnitude might not even be legal, it has to be approved by the FCC and the DOJ

Just checked the specs on this new phone on the T-Mobile spec sheet that was posted on T-MO News ad and that device supports both T-Mobile and AT&T's 3G Networks. I had to recheck it over 10 times during the day in case it was a miss print and they are still posted.
Has anyone else found any news that is different???

Yes, this says different. (Dang it, I can't post links. Search on Engadget.com for "T-Mobile G2x lacks quadband HSPA+, shatters dreams")
That said, I'm still curious to find out if anybody else has tried the the 2X or the G2x on AT&T yet. I'm not smart enough to understand what the lack of 850 3G means. Is that an upload speed? So would I be able to download zippily on the 2100 Mhz band but my upload would take forever?

Further adding:
I'm interested in potentially buying the Optimus 2X (900/1900/2100 UMTS) not the G2x (1700/2100 UMTS). Anybody able to explain why the 2X may not work with AT&T, or share experience with it working?

The 2x will give you 3G on only the 1900 band with At&t, and not on the 850 band. So your 3G coverage will be worse than phones designed for the carrier. It will not get 3G on T-mobile.
You may as well just wait for the "Thrill 4G".

what are the speed test for this phone on tmobile?
and so if it dosent get 3g will it be getting edge?

Just in case someone finds this thread again, the G2X DOES NOT support *any* AT&T 3G frequencies:

It was a screw-up by T-Mobile to say it did.

[Q] AWS Band 4 Verizon Dev Edition

Can someone please confirm with a screen shot that the Developer Edition of the Moto X has band 4 LTE AWS support for VERIZON. The only reason I did not purchase a Dev Edition of the Moto X is because I contacted Moto (after scouring the Internet for specs, Dev Edition says 750 Mhz LTE ) support and they specifically told me Verizon Dev Edition doesn't support AWS Band 4 for verizon.
Thanks.

Well, when I put my T-Mobile SIM in, I get LTE. Since T-Mobile uses Band 4, and not Band 13, that would imply the Verizon Moto X supports Band 4 LTE.
But T-Mobile or Verizon sim installed in the phone, it never reports Band 13 or Band 4 when connected to LTE.

AWS Dev Edition.

Yeah I've seen other reports of this. I was looking for proof from someone in a big city with Verizon's AWS network enabled to show me some really fast speed on a Verizon network.
Thanks for the reply though.

Does this help? Done the other night sitting in my living room... near Thorndale, PA... its not a big city, but its not bad.
And remember, just like with Band 13, there could be congestion on Band 4 LTE.. So don't expect speeds to always be this high... especially since AWS is 1700/2100Mhz so in building and such is not as good, and signal doesn't travel as from from the towers when compared to Band 4.

Oh, and here is a shot with my T-Mobile sim in my Verizon X. If the phone didn't support Band 4 I wouldn't get LTE on T-Mobile.

I've done speed tests on my dev x and at the same time ran a speed test on my wife's s3. I know the area has aws since my s4 showed I was connected to it. On the x I got about 70 mbps and on the s3 about 10 mbps. Aws is definitely supported on this phone.

Why would they put a chip in with different radio compatibility when all that is really different underneath is the bootloader?

Verizon didn't make the phone, Motorola did. If they put a different radio chip in, they'd have to pay for FCC testing/approval/certification on two devices, one of which is going to be a low sales model. Do you really think they'd offer it if they had to spend well over what they'd ever hope to make back for it?

Usually, Verizon phones require CDMA for Voice and Text. I'm not sure if this phone supports Voice/Text over LTE or even if Verizon's LTE supports that yet. But if LTE Voice/Text is not supported then the device would be Data-Only, no calls or texts

VoLTE is supposed to be coming soon, I don't know if that includes texts. It should work with the Verizon messaging app, as it sends text over WiFi on devices that have it.
I really hope someone can get it working 100% on Verizon, I've got a Moto X and I don't want to upgrade my phone to something >5" but still want a really good specced phone when I do upgrade.

I should clarify that by messaging I meant SMS. which will use CDMA. I glanced at the white paper for this phone and so no mention of CDMA so I'm willing to bet this phone will only work for AT&T and T-Mobile in the U.S. There is hope for a Z3w Compact since there is going to be a Z3 verizon compatible version. but we'll have to wait and see
And the original Moto-X is still a damn good phone, I wouldn't swap it out yet for probably another 6 months to a year at least

Yeah, I knew you meant SMS. There is an SMS app from Verizon called Messaging (I believe) that allows you to send SMS over data connections (well, its meant for WiFi but it should work over LTE.) With VoLTE coming soon, it might just work all over LTE but I'm not sure. It would be a bit annoying to have to use Verizon's messaging app but if it works that would be a nice upgrade path if I decide to upgrade soon. I'm also looking at the Galaxy Alpha. If I don't though, I would be more than okay sticking with the Moto X for a few more years.

As a follow up to my original post, I heard there may be a version available for Verizon in the US. Does anyone know if this is accurate? Thx

MetroPCS's original network was CDMA, but since the T-Mobile purchase if it uses a SIM it should work because that should use T-Mobile's towers but I can't say with 100% confidence, I'm a T-Mobile user

Question is - VoLTE isn't something that can be 'hacked', correct? If it were enabled on the Z3v, for example - it wouldn't just be a matter of extracting some files from there and voila, right?

Verizon VoLTE is not going to help. For now, it only applies when both parties to a conversation have it and are both on 4G. That's no substitute for CDMA calling.

Thanks for clarifying that it's a technology that requires the participation of both parties (though I guess that wouldn't be true of landline phones). Any mobile VoIP out there that doesn't suck these days?

They don't use it for land line calls. As it's currently implemented it only comes into play when two cell phones can both use it.
VZW employees I spoke with said they've been told not to oversell it because the benefits aren't really experienced that often.

I've activated on Verizon
My Z3c has successfully connected to Verizon's LTE network, once the other radios are disabled in the phone info screen (IOW the phone is in 'LTE Only' mode).
However, while it connects to Band 4 without issue, it doesn't see Band 13 at all, even though my other phone, a 2013 Moto X, sees it just fine. Is there any reason to think that Band 13 is disabled in the phone by default? Or is Band 13 varied enough that the phone only supports some specific part of it? Or is the Band 13 support just a typo in the specs? Note, this is the D5803 model, bought directly from the Sony Store here, not the D5833 model which lacks a bunch of radios.
---------- Post added at 03:42 PM ---------- Previous post was at 02:58 PM ----------
Never mind. After power cycling the cell radio, using the LTE Discovery app, I did, in fact, manage to connect to Band 13 as well. The signal on both is reported as being much weaker than on my Moto X, interestingly enough. Moreover, it switches to Band 4 after a few seconds, I suspect because Band 4 is a lot faster.

Hey, I'm looking to make the same move and wondering
1) How many months/days have you been using your Z3c on Verizon?
2) Did you activate on a new line or replace phone on active line? Any look-for's?
3) Are you using Hangouts for Google Voice? Any drawbacks compared with previous calling/texting experience?
*4) Are you able to add the Advanced Calling 1.0 feature for VoLTE?
Thanks!

Theoretically, it should work. All Verizon phones come unlocked, and the turbo has the correct bands, so there's no reason why it shouldn't work. But there's really only one way to find out. Just make sure it's definitely bands 3 and 7 in your area.

Before you do, I'd use LTE discovery on your current phone to make sure you're using the right bands. For example on my phone you can see I'm using LTE band 13.

I have seen people have success in Italy, Ireland, Kuwait. But I cant connect here in Norway despite having matching bands. Its better to hold off. Im having a big fight with Moto Tech Support right now.

Probably doesn't make any difference to you, but you are quoting the "official" Moto Maxx (XT1225) bands, not the "official" Droid Turbo (XT1254) bands. They are both Motorola "Quark" phones -- but one is branded for U.S. Verizon and the other is being marketed to Latin America countries. Besides the Droid Turbo having CDMA (for Verizon), they also have slightly different LTE bands.
On the end of your string you have LTE band 17. That's Moto Maxx-- not Droid Turbo.
The Droid Turbo has LTE band 13 instead. Droid Turbo has LTE bands 2, 3, 4, 7, 13.
And I put "official" in quotes, because QXDM software shows Moto Maxx also has LTE band 5, just as when it went through the U.S.A. FCC certification testing. Motorola apparently does not list that band in the "official" specs, as they decided to market the Moto Maxx to Latin America countries where LTE band 5 is not used. But it's still there.
For your purposes (Hong Kong), since all you need are LTE bands 3, 7 -- ostensibly either model should work.
However, the Moto Maxx has unlockable boot loader, we have root, and TWRP. If you are on XDA, those things are important, yes ? Whereas the Droid Turbo is very locked down. With root, I'm able to install and run Xposed/Gravity Box which gives me all the features of a custom ROM.

appreciate the info ChazzMatt. Wish I knew this before I paid up lol
In any case Im still relieved that LTE works just fine in HK.

International Galaxy Note 5 N920i on US AT&T - Updates?

Hi,
If I was to pick up an international Note 5 (N920i) for use in the USA on AT&T, how would updates work? The theories I have is that either:
The device will never get updates
Samsung will release updates directly to the device
I will have to use custom ROMs for updates
Given that I will root the device (thus the reason for buying the international model), I'm assuming #3 will be the correct path. However, I understand I could run a modified kernel with the stock ROM to allow that, and there only seems to be one ROM outside of the carrier (AT&T/T-Mobile) threads. Could I use an AT&T carrier ROM?
I'm just trying to understand all my options if I walk down this path.
Thanks in advance.

So, if I was running a custom kernel for root, I would basically revert the kernel to stock, run the OTA or via Smart Switch, and then re-root. Sounds easy enough. Any idea what the timing is like for updates on international versions as compared to the US variants?

One other question, are you using it on AT&T in the US? The N920i says it's compatibility is:
COMPATIBILITY:
2.5G (EDGE, GSM/GPRS ) MHz:850, 900, 1800, 1900
3.5G (HSPA+, UMTS/WCDMA ) MHz:850, 900, 1900, 2100
4G (LTE ) Bands:1, 2, 3, 4, 5, 7, 8, 12, 17, 18, 19, 26, 28, 40
But Droid Life indicates that AT&T also uses a 1700Mhz LTE frequency, which I thought was only T-mobile: http://www.droid-life.com/2015/02/0...sm-cdma-wcdma-lte-verizon-att-sprint-tmobile/
Looking at the wiki: https://en.wikipedia.org/wiki/Cellular_frequencies it seems that there is a seperate 1700 mhz 3G and 4G. Does that compatibility chart above indicate that since it has Band 4, it has 1700mhz 4G?

And from another perspective, I consistently connect to AT&T LTE bands 2 and 17 using the n920c (which differs from the "i" in supporting band 20 and not 28 - neither of which involves at&t.)
The only frequency from AT&T that the 'c' and 'i' models does NOT support is band 30. At the present time, I think there are only two AT&T phones supporting that band (n920a and the at&t edge+)

Thanks for that info. I am not even sure I knew about band 30.
Edit: just checked from another location and I am now on band 17.

I am on AT&T. The few times I have checked I was on bands 2, 4,and 5. I have never had a problem connecting to 4G with the 920I version.

Your comment on Band 4 proved my hypothesis. Thanks. Picked it up on eBay from Monoprice with a 14 day return to ensure against DOA. Thanks again.

Assuming the N920a is the AT&T Note 5 variant, the AT&T specifications page (https://www.att.com/cellphones/sams...sku7670223?WT.srch=1&source=ECPS0000000PSM00P) does not show band 30 support?

Are they just not published?

When have you ever known at&t to be forthcoming with information?
Here's an FCC filing for the n920A showing band 30 support (as well as all the other bands supported for use in the US):
https://apps.fcc.gov/eas/GetApplicationAttachment.html?id=2679337
(The n920a may supported other bands/frequencies, but the FCC filing won't show anything that isn't tested to work in the US.)

What I just found that's VERY interesting is that the n920i has FCC filings (FCC ID: A3LSMN920I) and the AT&T variant is obviously there (with FCC ID A3LSMN920A)
However, there's no sign of an FCC ID of A3LSMN920C. That would mean that my phone, the n920c, is illegal to use or sell in the USA. oops.
That makes things interesting, doesn't it?

I've been using the N920i on AT&T now for about two weeks and my speeds are excellent.
I tested LTE the other night on the speedtest app and had 50 Mbps download, fastest I've ever tested in my area (that even includes AT&T branded phones).
So no complaints here...

I concur with HNIC215. Had my phone about 4 weeks.

After realizing that this n920c is illegal in the US, I'm in the process of sending it back to amazon (and having it replaced with an 'i' model.)

Is there something about it not being cleared by the FCC that really bothers you or is it more of a just because kind of deal?

It relates to what I do for a living... I have a significant amount of contact with the FCC. It probably would never be noticed, but if it was, I'd be out of a job and possibly fined as well. The risk is too high when I'd be perfectly legal with the 'i' model.
Being that neither band 20 nor 28 is used in the US, the radio difference won't impact usage for me.

Makes sense to me, better safe than sorry when it comes to your job.
