Verizon LTE tab, will it work on 3g networks?

Hi,
Forgive me if this has been asked before but i did search and couldn't find anything that i was looking for..
so, I'm planning on buying a verizon LTE tab (4g + wifi) and i was wondering would it be possible to use it on a 3g network? The verizon rep i talked to said that yes this was possible but i'm not sure they knew what they were talking about.
Also, does it need to be unlocked to run on another network or does it come carrier unlocked? if yes, is that currently possible? because i asked verizon and they flat out said no..
Thanks and apologies again if i missed any threads related to these issues.

nevermind, got all the answers i needed
while LTE is backwards compatible with GSM, verizon uses the 700 frequency band which unfortunately is not what i was looking for

Typically 3G and GSM use different radio hardware, or even a different chipset. So a GSM LTE phone/tablet will have specific radio hardware for 2G GSM, 3G GSM and LTE. Verizon's LTE phones and tablet will only have CDMA for 3G and LTE. So, even if Verizon uses GSM frequency for LTE, it will still not operate on GSM networks, only LTE networks.

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?

Not true, I put a T-Mobile SIM in my Verizon Note 2 and made calls, sent texts, and used data on GPRS, EDGE, and HSPA+.

Nice! Was this native to the stock Rom or is a custom one needed that has this ability "unlocked"?

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.

AT&T LG G2 unlocked to Tmobile. Can I get HSPA+?

I just bought an AT&T LG G2 plan on unlocking it for Tmobile/metropcs (they merged in my area) Will I be able to get full connections to everything once I unlock the phone for Tmobile network? I'd hate to realize I wont get any data or get very slow data after spending so much money.
Since MetroPCS uses Tmobiles system in my area but also still use their systems can I choose if I want to use a metropcs or a tmobile sim card? Or are they both on GSM towers and so there would be no difference? 4G for MetroPCS is available in my area but so is Tmobile HSPA+ which is better?

Not if you don't have the 1700 AWS band...

not sure what you're saying. 4G is 2100. but other than that if i leave 4G area i wont have any reception at all?

4G uses different bandwidths. Not all carries use the same... Still the same old "GSM/CDMA" scenario, just a bit more relaxed.

AT&T LG G2on Tmobile...no signal! HELP!

Just bought an AT&T Lg G2 and unlocked it for Tmobile/Metropcs use and after setting APN settings I still have no connection at all. Im unable to send a single text, get online or anything. Im sure im doing something simple wrong. Tmobile has 4G in my area so i should get great speeds. Anyone got any ideas?
I've entered APN for both 4G and non 4G

Did you reboot? Probably did but it already, right?

yup I've rebooted multiple times. Went into Networks searched networks it found AT&T Tmobile and MetroPCS and a few others. i've tried AT&T tmobile and Tmobile LTE and Metro PCs...all with no luck

I'm afraid that the AT&T D800 does not support AWS/UMTS Bands, which are T-Mobile's main frequencies. I've just pulled this list from Wikipedia:
AT&T - D800
GSM 850/900/1800/1900
UMTS 850/1900/2100
LTE 1900(2)/1700(4)/850(5)/700(17)
T-Mobile - D801
GSM 850/900/1800/1900
UMTS 850/1700/1900/2100
LTE 1900(2)/1700(4)/700(17)
Namely, you are missing UMTS band 1700 which manages about 50% of T-Mobile customers' HSPA+ connection. That being said, the fact that you cannot connect to T-Mobile's LTE band 1700 is weird. Also, UMTS band 1900 should also work.
Perhaps you're in an area with ONLY UMTS 1700 which would not work with the AT&T LG G2. Do you know if there's LTE coverage in your area?

Yes I am in DFW area which is one of the largest LTE areas Tmobile has. I'm unable to get a connection at all. It says phone is for "emergencies only" I cant make calls, text, or use web.

Sounds like the phone is not SIM unlocked. Need to verify it is SIM unlocked. Also where did you buy it. If the phone was bought from a person it could have been reported stolen or lost and blocked from T-Mobile.

I bought it off Swappa. Ill try the unlock code again but it said it was unlocked. it doesnt come up with any error when i put the new sim card in anymore.

You're likely in an area that does not have HSPA 1900 coverage; and since you're AT&T variant doesn't support the band, is showing no service. Locking onto LTE wouldn't help as HSPA is required for voice access.
I created a thread in the Q&A asking for ways to enable the missing AWS band on our AT&T / Canadian variant handsets. It was doable on Samsung and am hoping it can be done on our handsets.

turns out MetroPCS had to activate it. you cant just stick a sim into a new phone. they have to activate it on your account. $15 later (yeah i know...its BS) but the Lg G2 is up and running and getting 4G speeds

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:

B2 (1900 PCS)
B4 (1700/2100 AWS 1)
B12 (700 ac)
B66

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.
