Hello people of Xda[emoji1]
I got my 8.4 two days ago, but it seems i can't uae LTE bands. My cell have 5 bars while the tab is stuck with H+. I use twin sim-card so i should be able to get atleast some bars right? Non rooted, all stock.

In the US?
Not compatible with the US Bands of any GSM Carrier for 4g LTE Yet, At&T is rumoured to get 1800MHz LTE band but it is not confirmed, and won't happen right away since we're speaking about implementing different frequencies which might mean different hardware and towers.

In France, LTE is working great on my SM-T805.

Sorry, forgot to mention, live in Norway and we do have the 2600MHz band available.

According to spec, tab s should support all: Hexa-Band 800, 850, 900, 1800, 2100, 2600 MHz

Samsung France told me it should work all over the world.
But your provider can or cannot activate LTE for your device.
I know some providers not always enable LTE' you must contact them...

My provider had to restart some of their services to make it work..

Freedom Mobile and ZTE Blade V8 Pro

I am helping a friend who uses Freedom Mobile in Canada to find a new phone. We bought the ZTE Blade V8 Pro. The phone arrived and the phone picked up the 4G LTE internet. It also works in streaming videos over LTE on Freedom. So internet works. Texting also works.
However her phone was not able to make nor receive any phone calls. I tried clearing the cache and resetting the phone, but the problem persists.
I tried to manually set the APN settings. No luck.
I tried to search for the networks. I was only able to see Home 4G. But there is no Home 3G. Is this why the internet LTE works, but not phone calls?
What is going on here? GsmArena said this phone is fully 3G 1700 AWS compatible.
https://www.gsmarena.com/zte_blade_v8_pro-8504.php
2G bands GSM 850 / 900 / 1800 / 1900 - SIM 1 & SIM 2
3G bands HSDPA 850 / 1700(AWS) / 1900 / 2100
4G bands LTE band 2(1900), 4(1700/2100), 5(850), 7(2600), 12(700)
Even ZTE's website says the same thing.
https://www.zteusa.com/blade/
MODES
GSM: 850/900/1800/1900 MHz
UMTS: 850/1900/AWS/2100 MHz
LTE: B2/B4/B5/B7/B12
Freedom's website also said both IMEI numbers are compatible, on the IMEI check. (This phone has 2 IMEI's.)
https://www.freedommobile.ca/plans-and-devices/bring-your-own-device-to-freedom1
Your phone is compatible.
If your phone is unlocked you can get started by signing up for a plan today!
The following network services will be supported:
HSPA+
LTE Advanced
Please note: Certain versions of older handsets may not have the ability to select the ‘LTE Preferred’ in the phone Network Mode settings even if the hardware supports the particular band. These handsets will not be able to connect to any LTE network.
See Coverage Map
Phone Information:
IMEI number: XXXXXXXXXXXXXXX
Brand name: ZTE
Model name: Z978

Could be an issue with VOLTE not being supported on that carrier. If data and text works but not voice Im guessing theyre in an area only covered by a certain band.

An update: My friend switched to Chatr.
She went to a Freedom booth. The Rep told her that just because it is listed as compatible on the Freedom Website, it doesn't mean that phone is fully compatible. In the case it only works with Freedom 4G and not 3G. And Freedom 3G is required for calls. 4G is only for internet and text.
My friend obviously was upset. Firstly this phone is supposed to be fully AWS 3G 1700/2100 compatible. All our research shows that it is. I am not sure if this is ZTE mis-advertising, or Freedom has compatibility issues even within their own AWS 3G. Secondly when a phone is listed as compatible on Freedom's website, it better be fully compatible.
This is BS on many levels. And I say this as a fan of Freedom.
She went right over to Chatr and switched to their $40 for 2.5GB plan.
Either way if you are a Freedom user, I say stay away from the ZTE Blade V8 Pro. It probably won't work.
In the future get a popular phone with lots of people saying "Yes it works" before buying a phone for Freedom.

US carrier support

Hello, I'm looking at the Global version of the Redmi Note 5 (Basically the pro. Referred to as the AI Dual camera on GSM arena) and I'll be using it in the US on Mint Mobile. Mint is a T-Mobile MVNO and I'm not sure how LTE support will be on this. If anyone has any info on this that would be great. I believe Mint mainly uses B4 and B12 but I could be wrong. I've been looking around and found mixed responses of it having good carrier support stateside and others saying it won't work.

I can confirm that the phone will WORK on B4 (1700mHz/2100mHz) and B5 if you live in the greater Myrtle Beach area. (Acquired from SunCom back in the late 2000's). I don't know if your area has B5. On your existing phone, get LTE Discovery from the Play Store and sample your most common areas first to see what bands are most prominent. Being where I live, the phone mostly uses Band 5 over 4 because of the lower freq; able to reach tougher places where the higher freq B4 can't reach.

Thank you so much for the reply. I'll give that a download and travel around. Since posting I did discover my current phone supports the same bands. So I'm less worried. :good:

Lte works on band 4, but not band 12 on T-Mobile. But, for me band 4 is enough, if I don't get lte the device will switch to 2g. 3g straight up does not work for me on T-Mobile, although I've heard that T-Mobile does not use 3g anymore in the first place.
All in all, for me lte works just as well as my previous phone (zte zmax pro)

I can see that. When B4 and B5 don't work the phone just switches to 2G but without internet so basic voice and sms still works. about 70% of the time after it switches to 2G it'll tap onto HSPA+ (3.5G, coined 4G) and I got that for a while until LTE reconnects. Rinse and repeat until I have to leave to go somewhere.

G7 Thinq won't connect to LTE on T-mobile...help

I just got a brand new international version of the G7 Thinq, it is the international version, with 128gb and 6gb ram.
I'm able to connect to T-mobile and make calls etc, but it won't connect to LTE even though I've been using LTE for years in my area with no issue on old phone.
T-Mobile support was not able to help me.
The highest it connects is 4g
I really do not want to return this phone to the seller, but I don't want to settle for a phone that can't connect to LTE like my old one.
Willing to try anything...any ideas?
Thanks

4G is LTE.

Do you have this phone and live in a LTE area? My old phone actually said "LTE" for the signal when it connected with LTE, are you saying this model phone does not actually say "LTE" on the signal bar?
Can anyone confirm that this phone says "LTE" at the top with an LTE signal?

I have this phone and I'm aware of that.
4G *IS* LTE.
You need to google what LTE is.
occasionally you will see 4G+ (downloading).

I just googled it and I've read 3 sites so far that says they are not the same.....
https://www.tccrocks.com/blog/what-is-difference-between-4g-and-4g-lte/
I'm not trying to start an argument. I'm just used to my phone displaying LTE and if you are saying this model does NOT display LTE, and displays a "4G" instead, then that answers my question. Some sites even say HSPA+ is 4g, and I know that is different than LTE.

On tmobile he is correct 4g is hspa+.. My g7 says 4g lte when on lte.. Did you do a network reset? Or call tmobile and ask then to redo your phone activation to make sure you register on there network right.. Maybe need a newer sim?

Check the APN settings

It's possible that the APN settings may need to be tweaked. I'd start there.

Mine says 4G+. Figured that was LTE.
and 4G (without 4G)+ is not LTE?

I've called T-Mobile, had them do a restart, had them check APN, etc.
I'm using the same sim as my old phone that gets LTE just fine, so it's not that.
I'm thinking something about this international version maybe doesn't support one of the bands or frequencies that T-Mobile uses in Chicago (even though it says it supports GSM worldwide)
I'm probably going to send it back as my 3 year old Motorola phone gets a higher tested download speed on a speed test than this new one without LTE. Just wanted to check if anyone else had the issue. Thanks

T-Mobile uses LTE bands 2, 4, 12, 66, 71, while the G710EAW, which I assume is the model you've bought, supports bands 1, 3, 5, 7, 8, 28, 38, 39, 40, 41 - so none of the TMob LTE bands.
There are six variants of the G7, G710EAW is aimed at Asia/Oceania and together with the G710EMW (64GB/8GB single-sim version of your variant) the only one that doesn't support at least two of the TMob LTE bands.
Sorry, hope you'll find a nice replacement

This is what I was afraid of. But I specifically purchased this model because it had the 128gb, the extra 2gb RAM, and dual-sim....I'll have to research if this is available in one of the models you mentioned but so far I've only seen the 64gb with single sim so I guess I'll have to find a new model. Thanks for the info.

Who told you this?
I have the G710EAW and it most CERTAINLY supports bands 2 and 4.
It's even labeled DIRECTLY on the box itself.
Don't get your information from the LG website. The site only shows which bands are used IN THAT REGION, not what is supported by hardware.

Don't believe everything you hear on the internet. Bands 2 and 4 are supported.
These are the bands supported by the G710EAW.
GSM: 850/900/1800/1900
WCDMA: 850/900/1700/1800/1900/2100
TD-SCDMA: 1900/2000
LTE: B1/B2/B3/B4/B5/B7/B8/B12/B13/B17/B20/B28/B38/B39/B40/B41
If a band is NOT supported, trying to select it will show "FAIL" in the engineering menu.
Example: band 25 is shown, but not supported. This will show FAIL.
It was the international LG G6 which had problems with T-mobile, as Band 2 was not supported (shown in service menu, if you select it it shows 'FAIL'.)
I sold one of these phones (I had 2) to a T-mobile user and he's happy.

I have also the 128 GB lg g7 eaw version. My phone shows 4g also. The speed test i have done is 60mbps both up and down and i am ok with that.
What is the diffrence between 4g and 4g lte? Should it display lte?

P. S. My operator is having lte in band 1 and 38 and are supported by the phone. Also band 2 and 4 are available and both connected with succes...

My G710EAW shows 4G+. Uaing Net10 on band 2 which uses tmobile's servers. I think each and every person here needs to stop crying wolf. Seriously.
If the US version shows LTE and the international version shows 4G+ I mean who cares if its the same damn thing?
https://www.4g.co.uk/news/what-is-4g-plus-ee/
4G+ is another name for LTE-A, LTE-Advanced or 4.5G and it’s basically a faster version of 4G. It works through carrier aggregation, which allows 4G phones to receive data from multiple bands in the 4G spectrum.
So while standard 4G only uses one band at a time, 4G+ can combine two bands for increased speeds. In EE’s case it’s the 1800MHz and 2.6GHz bands which are being combined

The information is from gsmarena. They have been spot on with this kind of information the last times I checked. However, it seems like they're off with the G7. I just compared my variant with their information and it's off as well. Thanks for catching this!
So in that case I can only think of one reason why the OPs phone would not connect to TMobile 4G: the network in your area is using bands that are not supported by your G7. However, this is quite unlikely, since these would be 66/71. From what I read, they have only been introduced in 2017.

G9 Plus Odessa Variant XT-2087-1: Conflicting Information re: FDD LTE Bands and Volte... ATT/T-Mobile users?

Could someone who has this exact model please confirm whether or not the FDD LTE band configuration is as follows?
Apologies for inconveniencing members with such elementary questions, but I have very impaired vision and there are few MASSIVE screen phones that work in the USA within my price range. I contacted Motorola and posted in their forum to be sure of this purchase, but to no avail.
Meanwhile every seller in the USA who claims to carry the XT-2087-1 Odessa variant is posting the FDD-LTE Configuration for XT-2087-2 (which lacks B12, B17 and B66) in their specification.
The config I think it is supposed to have is:
FDD-LTE Bands: B1, B2, B3, B4, B5, B7, B8, B12, B17, B28 and B66
If that is correct, why are Amazon sellers are stating that this phone cannot use Volte? I do understand that getting Volte to work on an international model might require using short codes and/or activating the Sim on a different phone before using it with the G9 Plus, or maybe rooting and a custom rom, but that's okay. Just want to make sure it's not hardware limited).
Is anyone here using this phone with ATT or T-Mobile or an ATT/TMO MVNO?
Thank you for your help!

I have that model but have no idea how to check that config

Thanks for replying. Are you using it in the USA and if you are can you tell me which carrier you are using and which LTE band is active? (Any Android app that checks network configuration can show the info).
How are you liking the phone?

No, I'm not from the US

Okay: I finally got a callback from Motorola international (who were no help at all as they referred me to the New Zealand website which is a different model).
However, the 4G LTE configuration for this exact model is listed on the Brazil website: https://www.motorola.com.br/smartphone-moto-g9-plus/p
It is as follows:
Bandas
2G - GSM 850/900/1800/1900 MHz
3G - WCDMA 850/900/1700/1900/2100 MHz
4G - LTE B1/B2/B3/B4/B5/B7/B8
/B12/B17/B28/B66
This means the only major band this phone is lacking for TMO is band 71. Yes, it is increasingly important for TMO, but even without band 71, this is one of the few Motorola Dual Sim phones to include FDD LTE 12/17 & 66.
It should be fully compatible with AT&T (except that Cricket won't permit it to use Volte on the Cricket network ... AT&T MVNOs apart from Cricket seem to be fine).
I am probably going to take a chance and order this on Amazon. I will report back on how well it works with my two ATT MVNOs --- still looking for a cheap prepaid TMO MVNO sim for testing purposes, if anybody has suggestions.

friend. save your files and try to reset it with your carrier's chip and put it later when you go into airplane mode there within 2 minutes you can take it out of airplane mode that might solve your case. Hope this helps . here always help me doing this
