LTE in Kuwait

Folks,
Please take a Min and help a me out. Me and wife are currently stationed and residing in Kuwait. Kuwait launched 4G LTE service late last year. The LTE network runs on 1800MHz band 3. the same Band as Telstra Australia, and O2 Germany. i have tired almost everything to get my LTE working, yet no luck. Now, the service run on the Iphone 5 and my LTE USB dongle with no problems.
List of things i tried.
1- flashed the following firmware
a- JB Telstra Australia
b- JB Orange France- LTE ON
c- JB SFR France- LTE ON
d- JB Retail Brazilian
Currently running JB O2 Germany
2- tired the service menu to switch to LTE and that didn't work.
3- Attempted to change the band but unable to select or change.
4- the SIM card work fine on the Iphone, so no sim issue
5- The service is activated

Sorry i think i posted in the wrong section. please move to the correct area

4G isn't really LTE. Since you said it uses the same band as used the other 2 providers you should be able to access LTE by flashing the correct radios or the whole rom & using an LTE sim
Sent from my XT925

Also O2 Germany has 800/2600 bands. From which carrier did you purchase your phone?

Roger/Fido Canada. the device is not branded

This phone don't have the 1800 MHZ band ... only 700/1700 mhz band There are two different phone ! One for north america ! One for the rest of the world ! This is just not a baseband question or rom problem... i have post it on many topic but many people think this is the same phone the Fido/Rogers support LTE in 700/1700 band .. and support only hspa to 21mbits ( no DC-HSPA up to 42mbits like others country ! )
Sorry ! You never get LTE !

Well. this just sucks big time!!!!! :crying: im glad someone have an answer after all

Just a quick thought. Did you check with your provider for a separate LTE APN?
I would probably be running the Telestra ROM to check this. Make sure your service menu reads "LTE/GSM/WCDMA". You can't select bands, but make sure it is "Automatic (2G/3G/4G)".
Looks like your phone should have the one that looks like "action.wataniya.com" (http://10.wataniya.com/customercare/configure/default_en_gb.aspx). Perhaps, also give them a call to check whether their site is up-to-date and this is the correct APN for their LTE network. Also, check your wife's phone. Is she using the same APN?
Just trying to help you troubleshoot.

Can you provide documentation? Motorola's site seems to suggest there is only one version based on their technical certifications. Which "model" are you using if I may ask. If you're using the "800/1800/2600" version, would you mind giving me the information on the back of your phone so I can dig up some info (FCC ID, Type, and IC ID). This will help look up documents in their technical specifications to confirm two models or more, if they exist.
It seems weird that Motorola would issue a XT926 just for a CDMA and only ONE XT925 number for multiple models (some of which do run CDMA)? It doesn't make sense from a business perspective either. Why produce many different GSM models, when you can produce one and alter the firmware (if for example it doesn't sell in Australia, flash a new ROM, repackage it, and ship it to Canada).
Just my two cents. If you have any of that info, PM me. I'd love to look into it.

Sir- I want to point out that wataniya is not the provider for the LTE in Kuwait. I had I different SIM card when I took the screenshots. In fact it’s a US AT&T sim that roaming on Wataniya Telcom in Kuwait. The LTE provider in question is Zain Kuwait https://www.kw.zain.com/kw/af/home.do?lang=en . plus I have tried the Telestra firmware and used the correct APN for zain; the same APN I used on the iPhone 5 and the USB dongle. To add, I tried using the LTE/GSM/WCDMA, LTE/WCDMA, and LTE alone options and had it at automatic (2G/3G/4G When I set it at only LTE I lose single completely. The other options allow me 3G H+ only.
UserDemos makes a lot of sense! There are only two modles out there. The 926 and 925. I believed that 925 can run on LTE 700 / 800 / 1700 / 1800 / 2600 as advertised by Moto. She I don’t know where the problem is? Anyways the info as showen in the back of the phone are Model XT925 FCCID: IHDT56NG9 TYPE:M0D46 IC ID:109O-T56NG9 . and the BIG CE number is CE0168.
Thanks for not giving up :good:

Yes I confirmed that you bought the wrong phone.
This what happened to me. I'm in Etisalat 4G, so if you want razr hd with enabled 4G lte you should buy it from Australia or UK.
I recommend Clove or Handtec the release date after 2 days.

Were able to figure this mastery out?

In many cases such as Milestone, Milestone 2 etc. there was a Canada / Latin American version and Europe / Asia version with different 3G bands - yet, the phone was called the same for all these versions (MS1 -> A853). Verizon's CDMA Droid (A855) was called differently and other CDMA carriers also had different name (such as MS A854).
This is the same thing, only about 4G bands.

There are 3 version of Razr Hd
XT926 for Verizon
XT925 for Canada, 4G band 700/1700/2100
XT925 for UK & Australia 4G bands 800/1800/2600

We understand what you're saying, but if you don't supply PROOF to back up your claims, then it's going to be hard for anyone to acknowledge you're right.
Which version are you using? Provide us with the info on the bottom, so we can see what it looks like compared to the other version.

No where in Moto website this info is listed. where are you getting this from?

There are 3 version of Razr Hd
XT926 for Verizon WITH LTE BAND FOR VERIZON ONLY ( BUT WORK IN HSPA WORLDWIDE TOO)
XT925 for Canada (and some others LATAM ) , 4G band 700/AWS ( no dual Channel HSPA up to 21 mbits )
XT925 for EUROPE & Australia 4G bands 800/1800/2600 ( and some LATAM country) ( Have Dual Channel HSPA up TO 42 mbits )
Is just not a baseband problem like many people say ... if the hardware don't support ... the hardware don't support ! Yes some phone have hidden band ! but not the case in the moto hd
I confirm again and again...
Proof is very difficult to find... but Motorola have made a bad move

If you want best battery go with the xt926 ... but you never get LTE . only 21mbits HSPA around the world !
if you want DC HSPA because no LTE ... buy the Europe Asia Version ... ( My carrier telus in canada have great DC HSPA coverage and speed are great near 25 mbits in download - i have sold my rogers version for the europeen version ... i never get LTE but my baterry is really good ... and have DC hspa in many many place )
if you want LTE choose the right phone before buying...
and oh yes ... the Motorola phone from U.S ... you can't unlock the bootloader !
and again don't listen people who claim is the same phone and this is just a baseband file problem !

motorola brazil razr hd has 2600mhz band.
I have one and all carriers here use this band...

[Q] Will Nexus 5 support T-Mobile USA HSPA+? [Answered] Yes it will.

On the Nexus 5 page it states the bands as
Network
2G/3G/4G LTE
GSM: 850/900/1800/1900 MHz
CDMA: Band Class: 0/1/10
WCDMA: Bands: 1/2/4/5/6/8/19
LTE: Bands: 1/2/4/5/17/19/25/26/41
Click to expand...
Click to collapse
Since I don't see 1700 MHz does that mean it won't support T-Mobile's HSPA+ speeds?
I'm currently on an iPhone 4 on T-Mobile and not having that band makes it kind of useless half the time. I'm not sure if my area has good LTE coverage some I don't know anyone with an T-Mobile capable LTE device.

I was getting ready to ask the same question, but I believe you'll need to have 1700 to play with HSPA+. That's what was true for my HTC One at least -- hence the reason I had to cancel my developer edition HTC One order.
Although I didn't give you a full answer, I hope this helps a bit.

If the phone doesn't support AWS HSPA+ then this is bad news for Canadians on Wind or Mobilicity. LTE support doesn't help when your provider has no LTE network.

Would tmobile really sell this phone if it didn't work with their HSPA+?

Major fail if this is true. Where is my N4?

I think it will work since it has WCDMA Band 4
http://www.rfcafe.com/references/electrical/wcdma-band-frequency.htm

They're using channels, not frequencies. It has the channels T-Mobile uses for AWS HSPA+.
T-Mobile is using channels 2 and 4 for HSPA+, as far as I know, and those are supported: WCDMA: Bands: 1/2/4/5/6/8/19

FYI - HSPA = WCDMA, not GSM, so looking at the GSM frequencies isn't going to tell you anything for HSPA+ connectivity.

Cool. Thanks for the info.

WCDMA Bands 4 and 2 is T-Mobiles HSPA+ so this supports all bands for T-Mo and then some!
It even supports Sprint.

It wouldn't be the first time that band / frequency jargon confused the end user, even when the end user hopes to be relatively technically apt.
But I think the answers given are correct for the reasons given.
It's all the more confusing because different manufacturers advertise bands/frequencies in different ways - for example, look at how Apple advertises their band/frequency support vs how Google/LG does.

My guess is that it doesn't support LTE because they are using Band IV 1700/2100Mhz, which N5 doesn't support.

yes it will support T-Mobile's LTE. As you stated Tmo uses band 4, the N5 has band 4 support.

From my understanding the Nexus 5 does support HSPA+.
My question/concern would be, does it support HSPA+ 42Mbps or 21Mbps?
I only ask because of a chart I saw posted on G+ stating that the Nexus 5 supports 21Mbps HSPA+. Thanks.

Yes. I believe the difference is that the US version has the 1700AWS band for T-Mobile. Global has the 2100 band that works better overseas.

Ok thanks I don't have TMobile or one of their subsidiaries anyway and tend to travel over seas in the summer so looks like I made the right choice anyway

Thanks for the help guys

I'm thinking of getting the G. I will use it in Germany for 3 wks next year, and use it once (2-3 wks) in Taiwan when I visit my friends and family. I will mostly use it in the US trying out different prepaid plans. I think I'd better get a US version, but is there any chance to get 3G in Europe or Taiwan with a US version?
Thanks.

No with the US version you will NOT get 3G in Europe or Taiwan. You will get 2G however. If you want 3G overseas you need to the global version but you lose T-mobiles AWS band support.

thanks. Is there a phone (moto x, nexus 5, or anything) that support 3G band of all carriers in all regions?

A thing that I've noticed in the reviews is that the US versions of the phone, the cases (at least the black one) has a "metallic" look on that M on the back while the Global / European version that M it's only glossy.

Just got my US 16gb model yesterday via Amazon. Back cover has a glossy black "M" logo, nothing metallic about it.
Bummer to hear this phone won't do 3G in Europe, I went with the USA model since I just moved over to T-mobile, and a lot of the 3G signal in my area is still on 1700 mhz. My AT&T phone was getting 3G in a lot of areas, but just enough EDGE data to annoy me and make me buy the G.

Frequency check

Hello all. Considering a move from the current phone to this, but wanted to check this first. As I read the specs for this phone, it appears that it supports *both* CDMA and GSM at this same time, meaning it truly is carrier agnostic. If this is the case, it would then outweigh the major drawback of not having expandable storage. (Owncloud is being planned to take care of that shortcoming).
So, can someone verify bandwise if this is the case? Looking to jump from AT&T to T-Mobile if this turns out to be the case. (Looking for the inclusion of Cdma as then Sprint and Verizon become available)

I had a broken phone so I bought this nexus 5 thinking that regardless of the difference between the two, the radio should still be compatible with it since it is supposed to be a world phone. I just recently realized that the radios are different (apparently the D821 isn't allowed to use CDMA bands).
I know there is the Nexus Field Test APK, but I don't think that would enable those CDMA bands.
I won't be back in the states for another three months, and at that point, my service contract would end with Sprint, so I could either buy a new phone, or go to another carrier (maybe T-mobile, or any pre-paid provider) and shop around.
But, as for my question, is there any way to get the D821 to use the Sprint Network?

See below.

GSM networks are the exact same on either device
Some NA carriers use CDMA instead of GSM for 2G. A D821 won't be able to get 2G from those NA carriers that use CDMA, a D820 will get 2G anywhere in the world on either GSM or CDMA.
D820's extra band 19 on WCDMA is pretty much negligible
Some LTE bands are shared, but most are different. If you're lucky/pre-searched before choosing a carrier, you can get a D820 to work elsewhere/D821 to work in NA on LTE if the carrier happens to use one of the LTE bands that are shared between the D820 and D821.
D820:
GSM: 850/900/1800/1900 MHz
CDMA: Band Class: 0/1/10
WCDMA: Bands: 1/2/4/5/6/8/19
LTE: Bands: 1/2/4/5/17/19/25/26/41
D821:
GSM: 850/900/1800/1900 MHz
WCDMA: Bands: 1/2/4/5/6/8
LTE: Bands: 1/3/5/7/8/20
Also, it has been proven possible to enable LTE band 3 & 8 on the D820, as well as band 2 & 4 on the D821 with modifications, which could make your D820 work on more non-NA carriers, and your D821 work on more NA carriers.

So there is no software enabled modification that I can use that will enable the CDMA bands (not the LTE bands) to be used on a D821?
I know of that forum link at the bottom of the post, but, as far as I know, CDMA is required before the use of LTE on Sprint.

The D821 lacks CDMA support completely.
As far as I know, Sprint uses bands 25, 26 and 41 for LTE so the D821 has no way to get LTE either.
