USA: xt1644 on AT&T network. - Moto G4 Plus Questions & Answers

Here's a simple question that gets shockingly complicated.
I have a xt1644 on AT&T, and have my previous phone (zenfone 2) on T-Mobile.
When I used the zenfone 2 on AT&T I could never get an LTE signal, but when using the zenfone on Tmobile i get LTE all the time.
On AT&T, my zenfone said it was in HSPA mode. Now my MG4+ also shows in HSPA.
Interesting sidenote. I travel across the country, and it doesn't matter what market I am in, same results across carriers (no lte on AT&T, but get it on Tmobile.)
Is there any way to figure out what bands which carriers are using, and perhaps add the LTE band for AT&T to my XT1644 radios???
Yes, even I am confused.. but that's it in a nutshell.
Ongoing question: any good roms out of testing for US/xt1644??
Mark

I am using the Cellmapper app. If you are rooted, it can read the LTE band frequency directly from the Qualcomm radio.
I have used the XT1644 with both metroPCS (T-Mobile) and now Cricket wireless (AT&T) and the latest has more consistent LTE connection.

What does "Global Ready" mean for the Verizon Note 3?

I am a little confused about some information I found on Verizon's Note 3 Page. It says that the Note 3 will be a CDMA phone but then lists the following bands:
CDMA Data – 1x and EVDO Rev0/RevA
LTE: B13 (700MHz)
Global Ready (GSM/EDGE: 850/900/1800/1900; HSPA/UMTS: 850/900/1900/2100 MHz)
(original link: http://www.verizonwireless.com/b2c/...t&action=viewPhoneDetail&selectedPhoneId=7194)
Does it mean that if sim-unlocked, it can be used internationally, and how, if it doesn't take a sim card? If it can be used internationally, I would much rather buy a Verizon (for the US) instead of AT&T. I use AT&T only because it's a GSM carrier.
I don't have the answer but I can recommend you to contact Samsung wireless. They certainly have much more credibility.
Good luck

All Verizon 4G LTE devices take SIM cards. They have to, since LTE is based on GSM. Also, historically, Verizon doesn't carrier-lock the LTE/HSPA/GSM part of their 4G LTE phones, so SIM cards from other carriers will work in a Verizon LTE phone out of the box.

I found the answer here, by the Answerer #2. The 4G/Data part of a global ready phone is GSM compatible, and only that part can be locked for data internationally; the calling part will still depend on CDMA in other countries. If that information is accurate, I will stick to an AT&T Note 3.

Truth be told. LTE has more in command with CDMA in terms of radio/air interfaces. It covered within 3GPP standards (GSM then EDGE, the UMTS, HSDPA, etc). Rather than 3GPP2 for CDMA1x and EVDO. That's why Alcatel Lucent had a leg up on LTE since its deployment is more akin (specterally) to CDMA. But they dropped the ball, and except for the US and Some Asian markets, the rest of the world has 3GPP based networks deployed.
the Simple version, is LTE is not directly compatible with any 2G/3G technology, but since its covered in 3GPP, the standards evolved quicker to ensure GSM/EDGE/HSDPA interworking.
And beyond that.. what most people dont know, that interworking doesnt really work that widespread yet. In the US most mobile handsets operate on dual frequencies (especially all VzW models, ATT models are catching up) so they effectively talk CDMA1x and LTE at the same time. iPhones do not support that capability, but GSM has work arounds to allow talk+data.
i'll go back to me hole now
(btw.. anyone with iOS7 and ATT.. what out you've got problems you dont know about when going back forth from 3G to 4G.. I know since at work we talked about how to fix it..
I believe a rumor was that it has the same LTE baseband chip as the iphone 5s so that you could potentially use the Verizon version on AT&T and T-mobile...any truth to that?

Global-ready is basically verizon's way of saying that it has a GSM 3G radio as well as a CDMA radio. That allows the phone to operate in Europe where there is no CDMA service. You can purchase international service from Verizon, or purchase a SIM from a European carrier while overseas. All verizon 4G phones have a GSM 4G radio anyway, because LTE is GSM.
(This means that with an LTE carrier in Europe, any 4G Verizon phone can get data in Europe even if they can't place voice calls (VoIP still possible)).
If I am not wrong with what I am saying, Verizon LTE phones only support LTE BAND: 13, which means that IF you are willing to use 4G with different carrier, they have to support LTE band 13. I have tried to use my Verizon Galaxy Note 2 in South Korea, I was only able to use 3G network via WCDMA, I wasn't able to get LTE service at all. Correct me if I am wrong.

the different N3 variants due in fact support different LTE bands, so you are correct. Minor point not worth nitpicking from earlier post, GSM is not LTE. they both evolved from the same 3GPP standards body, but portions spread spectrum nature of LTE is more similar to CDMA than GSM.
I went to Korea last October, and they wouldn't allow prepaid 4g LTE. They would only allow 3G for prepaid service.
I had a note 2 rooted and custom rom when I went. I'm a US citizen and you have to wait about 2-3 days before you are allowed to sign up for any plan on what they told me.

Any H870DS users getting LTE?

Hi Folks,
I thought I had found a gold-mine here in the United States in the H870DS because it has the quad-DAC and the bands look to be compatible with AT&T and T-mobile. The seller listed band 2 LTE and sadly, according to the box, it is not supported and this is one of AT&T's main bands in my area in California. It still has band 12/17, so, I figured I'd be okay. I cannot for the life of me get it to connect to any LTE though. I've checked and re-checked the APN settings, the network settings (4G preferred) and am out of ideas. Does anyone have this phone and have you successfully gotten it to connect to LTE in the United States? I don't have a T-mobile SIM anymore to try.
-Collin-
I believe AT&T SIMs have issues with LTE on non-AT&T devices until the device IMEI is added into their system.
I am not an AT&T user so I forget the specifics but people often have to call in and have the device IMEI added to their account.. or sometimes this happens automatically after a few hours.
What bands are listed on the box? The thread on XDA listing all the bands shows your model as having B2 LTE (Possible the thread is not correct though) https://forum.xda-developers.com/lg-g6/how-to/info-lg-g6-models-bands-t3571221
I have searched some of the AT&T user forums, it is because different areas have different coverage and certain bands are not licensed properly, so you might not get any LTE signals. I do not know if that is true. But my G6 sure does not have LTE whatsoever.
Thanks for the replies guys. Well, I managed to pick up Band 4 when I walked down the street. I still cannot get 17/12 which is weird because it's the primary LTE band for AT&T. The bummer is that now that I know LTE is working, I can 100% confirm that LTE Band 2 is missing. The eBay listings are wrong and the XDA listing is wrong. I've attached a photo of the box. Oh well
-Collin-
I was interested in picking up an 870DS unit myself. I noticed the discrepancy when it comes to band 2. That had me worried, so I did not pick it up. The 870 DS box shows that band 2 is missing. I have to assume that is correct, so I did not buy.
Sorry to hear that i was thinking of picking up the Korean version myself but if I can't get reliable LTE on att no thanks. I wonder if you could return it to the seller since its technically false advertisement
Well this is unfortunate. I just got mine from Ebay today and was wondering why I couldn't get an LTE signal. The seller did list Band 2 so I'm hoping they will refund my purchase or there is a way to edit the radio.
Sorry for the off-topic question but could anyone tell if the H870DS would support 3G simultaneously on both radios (or 4G on one and 3G on the other simultaneously)? If so it would be worth mentioning here as well.

I am using T-Mobile SIM at SIM 1 and my home country carrier's SIM at SIM2.
It is getting LTE at SIM 1 and UMTS (roaming at AT&T network) at SIM 2.
Fi (T-mobile) is working perfectly for me, full LTE. Cricket (At&t) is hspa+ but no LTE.
For the price I am not unhappy even though I usually use cricket as my primary data sim. It's not what I expected but I knew going in I was shooting craps as there just wasn't a ton of information out for this H870DS variant. It's not a huge upgrade over 3t, just needed to switch it up for a while. I am quite enjoying the screen, camera, and HiFi dac without losing my 2 sim setup.
Edit: Sim one does have full LTE while Sim 2 does not.
The references definitely need to show that there is no B2, B17, or B30 for ATT users though, pretty much a let down there.

I actually got Band 4 to connect on AT&T, but it's pretty sparse and not reliable. I switched that line over to T-Mobile and it works perfectly just as you describe.
I like the phone a lot more than I thought I would. It feels so solidly constructed and the camera I really missed from the V20. I prefer this camera to the one on my S8 9 times out of 10. It's a hair slower to focus, but everything else is better for me.
What's odd is that on AT&T Band 12 is supposed to be compatible with Band 17. On T-Mobile, I connect to Band 12 just fine, but not on Cricket. Oh well, my Cricket line has been canceled anyhow

I'm in San Francisco and unable to get LTE on AT&T or T-Mobile on the H870DS. These LTE bands are listed on the box: 1, 3, 4, 5, 7, 8, 12, 20, 26, 28, 38, 39, 40, 41.
Hi there,
I'm in new Mexico on a at&t go phone plan and on a h870ds.
and I'm defenetly getting LTE.
Does the LG G6 actually reveal the used channel and so the frequency band?
On many Android phones this information will show up after dialing *#*#4636#*#* and tapping "Phone Information" - on the very bottom of this screen you will find a list of available cells including their channel number (called EARFCN for LTE/4G, UARFCN for UMTS/3G and ARFCN for GSM/2G). You can then lookup to which frequency band the EARFCN/UARFCN/ARFCN belongs, e.g. at http://niviuk.free.fr/lte_band.php
Take a look at the 'LTE Discovery' app. The free version will probably have what you need.

I can confirm the lack of LTE on T-Mobile in Southern California as well. Very odd as others are reporting success getting LTE on TMO in other geographic locations. :crying:

Doesn't seem odd at all considering that according to frequencycheck.com, some key bands are missing:
T-Mobile LTE Bands
B2 (1900 PCS)
B4 (1700/2100 AWS 1)
B12 (700 ac)
B66
ATT LTE Bands
B2 (1900 PCS)
B4 (1700/2100 AWS 1)

As noted on the box as well as other first hand accounts, the H870DS does support both B4 and B12 required for T-Mobile. My G3 and my wife's previous 860N both connect(ed) with B4.
On top of this, I now have a solution to the problem via updating the APN settings. The magic change was simply adding ”xcap” to the APN Type setting and setting the Network Mode for SIM1 to GSM/WCDMA/LTE auto radio button.

It's possible that if you're in an area where only T-Mobile B2 or ATT B30 is available then you wouldn't have LTE.
Was finally able to get 4G LTE in AZ on Band 4. Create a new APN with these settings and make sure network is GSM/CDMA/LTE Auto.
Edit: Also, I had AT&T update their system with the IMEI number of this 870DS that I'm using. That might have something to do with it. It took a couple of weeks too.

US996 cannot get LTE properly

I just got my factory unlocked US996 version from Ebay. I have 2 sim card tmobile and a Mexico AT&T, both work great on my galaxy s6 (g920t)
But with the new US996:
With the t mobile has LTE, but very poor signal, 1-2 bars indoor and 3 outdoor.
With the Mexico AT&T sim, It stuck with 3G only
According to LG official specs it has all the LTE band G920T has (except band 8), Is there a reason why it's not working as expected?
Is there any service menu or something that I can verify the support bands?
I'm lost

Differences between A320F/DS, A320F, A320FL and Usability in the United States?

Hi,
So, I'm interested in getting a cheap 4.7" Android phone to use in the United States and sometimes in Canada. I zeroed in on the Galaxy A3 2017. The model that works best in North America is the A320Y, but so far I've only been able to find it online at some store in New Zealand. Since finding the answer to the question, Will shipping the device from NZ to the United States cost customs fees (and if so, how much)? is a question harder to answer than the question, Where is Jimmy Hoffa?, I've begun considering getting one of the models listed in the title of this thread.
But there's a problem. Those models in the title don't work on US LTE. Actually, according to frequencycheck.com, the A320FL has one LTE band (Cricket/AT&T) and the other models have none of the LTE frequency bands. I wonder if frequencycheck.com is accurate. I'm also wondering if there are other differences between those models. I'm also wondering what happens if I put a Cricket SIM inside these phones. Even though frequencycheck.com says I will get no LTE bands, will putting a Cricket SIM inside suddenly activate an LTE band?
The other question I was wondering: Do I even need LTE if I don't care much about download speed? Maybe HSPA+ or whatever it is will be good enough? If I don't have LTE, will I get less reception indoors or outdoors, or will I get the same exact reception/coverage but just be relegated to 3G/4G/HSPA+ service? What is the benefit of LTE besides data speed?
Finally, which one of these models has the most ROM support? Can they all be bootloader unlocked?
I know I'm asking a whole bunch of questions at the same time. Sorry. I appreciate any help I can get with this!
To answer some:
That website appears to be accurate. Doesn't only list AT&T for a320fl once expanded.
As for SIMs activating bands, I haven't seen it on Samsung, only RRC Release, VoLTE, LTE CAT, maybe individual CA combos. The disabled bands are shown as CAL_DEFAULT vs CAL_PASS. Guess it's like Snapdragon.
HSPA+ vs LTE
The range of 3G/4G is close with the same frequency, but 4G performs better at cell edge (low signal).
Speed (anyway)
Well, 3G is usually given its own spectrum at first, then the 2G is refarmed into 3G. Today, 3G gets refarmed to 4G. This leaves 3G with a small amount of spectrum, it becomes prone to interference. It's bit like multiple tv/fm stations on the same channel number. Other 'tv/fm stations' have to be filtered out by the phone, this lowers the speed. 4G gets some too, along with echoed complex signals, but it gets less.
3G supports up to 5MHz per carrier, 4G up to 20MHz. 3G can have carrier aggregation, so 5+5+maybe 5. Expect up to 2 carriers (not every combo) on 4G, unless a specific SIM is detected in specific phone models. Along with that, 4G can have better spectral efficiency.
If you are going with 3G(HSPA, sometimes called '4G') anyway, you should know that there are these states (usually called fast dormancy) to save power.
DCH = Full speed.
FACH = Up to 32kbps. 4kB/s. Maybe RRC Release downgrade is visible (H+ to H).
PCH = No data.
Anything below is further away from data.
For high performance, keep the speed above 4kB/s, at the cost of battery. LTE has a faster start.
Sometimes, the speed is simply constrained by backhaul, the internet access that goes to the tower.
Thanks. So, to your knowledge, the F and F DS variants shouldn't work on LTE in the United States? I was in a live chat session with someone on Samsung's UK website and she said that the F variant would work on LTE in the United States. I then sent them an email to confirm and they replied with:
As per our resources from our technical review, the following Network is available in our Samsung Galaxy A3 (2017) for the US.
Network
Band: Quad
GSM 850: YES
GSM 900: YES
GSM 1800: YES
GSM 1900: YES
UMTS 2100: YES
GPRS: YES
4G: YES
HSDPA: YES
Works in the US: YES
I replied to ask them why frequencycheck.com lists no LTE frequencies in common for the F variant on AT&T. I'm so confused.
sm-a320f / sm-a320f/ds
According to every other (not alternating) source the LTE band 2 and band 5 is supported in the US (and the entire spectrum of these bands). So, it supports some bands. Check if the signal of those bands (for your mobile network operator) are available in your location. Ask again, specifically for band 2 LTE(4G).

LG V20 VS995 in the UK?

I'm in the UK and about to buy a LG V20 VS995 from Hong Kong off of Ebay. Pretty sure I've checked the available frequencies here especially the 800 & 900MHz bands as these are the ones which travel the furthest and are able to penetrate buildings better than the higher frequencies. I've attached a table of the main UK networks and what bands they use. So can anyone let me know I've got this right before I purchase. Many thanks
Hi
I am in the UK also and currently using O2 with no problems. I have also used an EE SIM again with no problems. The only thing you need to be aware that the VS995 will not pick up the SIM APNs automatically, at least that is what I found, so you will need to find the APN for whichever network you use. There are off-line APN finders you can find via Google. Hope this is of some help.

Hi, the LG V20 VS995 doesn't support ALL the bands used in the UK. It doesn't support one of the LTE bands used by Vodafone - the 2100Mhz band. So if you're on the Vodafone network, you may find that 4G/LTE speeds might be slightly slower.
I got all of this information from frequencycheck.com and it's usually where I get all my information on the bands that smartphones support.
The best option if you want to get a V20 that supports ALL bands in the UK (at this current time), is the LG V20 H990DS (Taiwanese Version).
That is the variant that I own and it supports every single band used in the UK.
The only other variant that supports all bands is the LG V20 H990N (Hong Kong version), but it only has Cat6 capability as opposed to the H990DS's Cat12 capability. Therefore, the maximum speed you'll be able to get is 300Mbp/s on the H990N - whereas on the H990DS you can get up to 600Mbp/s.
I got this information from techwalls.com/lg-v20-model-numbers-differences/
I hope that helped.

I'm not really sure that's true according to gsmarena it does support band 4(1700/2100) admittedly that's not the same as 1(2100). I'm sorry but in my ignorance I don't know . Maybe someone who is more enlightened could tell us what the difference is. See here.
Also the bit about the Cat 6, 9, 12 with LTE does not really bother me. For the VS995 it's LTE-A (3CA) Cat12 600/150 Mbps but for the H990N it's LTE-A (2CA) Cat6 300/50 Mbps. Now I ask you is anyone on this planet going to realistically even touch or even dream of a download speed of 300Mbps on a mobile network. I'm not even remotely getting this on my home fibre and we're watching UHD movies!!
Did find this
LTE Band 1: This is one of the paired bands that was defined for the 3G UTRA and 3GPP rel 99.
LTE Band 4: This LTE band was introduced as a new band for the Americas at the World (Administrative) Radio Conference, WRC-2000. This international conference is where international spectrum allocations are agreed. The downlink of band 4 overlaps with the downlink for Band 1. This facilitates roaming.
I guess I'll soon find out, not sure how though

To be on the safe side, I would just go for the H990N or H990DS. You also don't get the horrible, disgusting Verizon watermarks and logos (software and hardware) if you go with either of the H990 variants. But if you're not going to be using Vodafone, it doesn't really matter - because Vodafone is currently the only UK network that uses B1(2100) for 4G/LTE. Have you already ordered the phone?
i have a h990n in the uk all networks with full 4g
Don't buy CDMA phones for use on GSM carriers, or phones not specific to your region! Though nearly all CDMA phones from Sprint and Verizon in the USA support GSM protocols like 2G: GSM, 3G: UMTS/HSDPA/HSPA+, and some LTE bands, they are not always accessible. VS995 doesn't support Vodafone UK's LTE B1. I ran into problems with invalid sims and poor coverage because not all bands were unlocked by Verizon. If you want a V20 save the hassle and buy a GSM unlocked V20: US996, H990, H910 (won't get OTA, so flash H915 KDZ), H915, H918.

Don't buy CDMA phones for use on GSM carriers, or phones not specific to your region! Though nearly all CDMA phones from Sprint and Verizon in the USA support GSM protocols like 2G: GSM, 3G: UMTS/HSDPA/HSPA+, and some LTE bands, they are not always accessible.

Had a look at the above link and have got the following compatibility
GSM: 2G, 2.5G 100% (2/2)
UMTS: 3G, 3.5G, 3.5G (4G speed) 100% (2/2)
LTE: 4G 75% (3/4)
So I'm chuffed especially after reading this concerning the band/frequency I'm missing...
2.6GHz frequency band
The 2.6GHz band is the other frequency which was auctioned by Ofcom and it’s essentially the opposite of the 800MHz band. So it’s not great at travelling over long distances, meaning that masts need to be closer together to deliver reliable coverage and as such it’s not so suited to rural areas.
It’s also not all that adept at penetrating walls so indoor signal on the 2.6GHz band won’t always be perfect.
But on the other hand with 35MHz blocks available it has a high capacity. So it can cope with thousands of simultaneous connections, which in that sense makes it a good fit for cities and other busy areas.

I ordered the phone and hope to get it in the next couple of weeks and I will post back my experiences. I ended up getting it at a good price too

Hi
I am in the UK also and currently using O2 with no problems. I have also used an EE SIM again with no problems. The only thing you need to be aware that the VS995 will not pick up the SIM APNs automatically, at least that is what I found, so you will need to find the APN for whichever network you use. There are off-line APN finders you can find via Google. Hope this is of some help.

Out of curiousity were you able to update from Nougat to Oreo? I had a quick preliminary look and didn't see any straightforward method via official channels.

No, very few American V20 users have been able to update to Oreo as the providers have not released Oreo for the phone. To keep ahead with security updates I use a custom Rom on my V20 (Alpha Rom ) but you need to have the Bootloader unlocked and the phone rooted to use it. Hope this offers some clarity.

Will probably stick with the stock ROM for a while until I'm settled in with the phone. Has choosing the Alpha rom negatively affected the performance of the camera or sound quality at all?
Some of the reasons for getting this phone is the renowned DAC and the camera esp in manual mode (apparently auto could be disappointing).

No negative affects. Alpha Rom is actually based on the last stock Rom from Verizon with some modifications.

Okay thanks for all your help. I'm expecting to get my phone sometime before Christmas
Just looked at the delivery estimate and it was anywhere between Sept 4th and October??th and it was ordered about 10 days ago. I guess it's to be expected coming from Hong Kong.
:good:

Well picked up my new V20 VS995 today and before I launch myself head long into customising it I've posted some questions in the main thread here I would really appreciate any help you might be able to give. I was going to post it here but I thought that would be unfair to load you with a barrage of questions.
The whole process seems so much more complicated than with my Note 4 and I there is a lot less handholding esp with the AΩ ROM'S initial post. For a relative novice it seems an absolute minefield.
