TL;DR at the bottom..
Hello,
So I have had the OnePlus one for just over 3 months now, and I'm currently running 100% stock OxygenOS (even thought that doesn't change the outcome of the question)..
Here in Australia we like to make things so much more confusing than they actually are, and this is truly the case when it comes to mobile phone network names. We currently have 2G, NextG, 3G, "4G" (HSPDA), 4G LTE, 4GX LTE, 4G Plus LTE, 4G+ LTE, and this makes things incredibly confusing when trying to work out if your phone is compatible with a service plan. Currently, I am with "Amaysim", who offered "4G" (HSPDA) plans only, until 3-ish weeks ago when they changed all their plans to 4G. I have already upgraded my line to 4G (free of charge), but Amaysim uses Optus' cell towers. Optus offers 2G, 3G, 4G (HSPDA), 4G LTE and 4G Plus LTE, my phone is working on everything but the latter two (as I don't get the chance to see if they are working till the 1st of May).
Now that we have the backstory out of the way, my question is, will my phone work with the 4G Plus network. From Optus' site:
OPTUS 4G PLUS NETWORK SPECTRUM FREQUENCY COMPATIBILITY
The frequencies we use on our 4G plus network to deliver superfast 4G include LTE 700MHz, LTE 1800MHz, 2100MHz, 2300MHz, and 2600MHz. Depending on your device compatibility, you can access some, or all, of the 4G Plus network. We're using the 700MHz spectrum to expand our network nationally, so If you want to future-proof your device, choose one with the "4G in more places" symbol to access our 4G Plus network wherever it expands. You'll be able to enjoy faster downloads and Internet browsing in loads of new places.
So while I will have LTE as the OnePlus One Supports LTE band 1(2100), 3(1800), 4(1700/2100), 7(2600), 17(700), 38(2600), 40(2300), Optus advertises elsewhere; If your device supports 700MHz/Band 28 – it’s a 4G Plus device.. So while the OnePlus One does support 700mhz, Optus says it's band 28, while on the OPO 700mhz is band 17..
TL;DR: My network advertises that their "4G Plus" is on the 700mhz/band 28 frequency, but the OPO supports 700mhz/band 17 frequency. Is this the same thing, but because of North America to Australia differences or whatever it's different?
I checked the Wikipedia article for the technical specifications of the different bands. Link: http://en.wikipedia.org/wiki/E-UTRA#Frequency_bands_and_channel_bandwidths
Band 28 uses wider spectrum range for transmitting data. Band 17 uplink is from 704 to 716 MHz and downlink is 734 to 746 MHz, whereas band 28 is 703 to 748 and 758 to 803 respectively. Band 28 has wider range of channel bandwidths (3, 5, 10, 15, 20 versus 5, 10). Duplex spacing is also different (30 MHz on Band 17, 55 on Band 28).
In theory my conclusion is that it will not work.

Hmmm alrighty. Cheers, I guess if I decide that I really do need 4G "Plus" that I will unlock band 28 using the band unlocker guide.
Thanks!
Hi,
my name is Andrea and first of all thanks to give me your attention.
I'm in europe, italy, and was watching Z3 model d6683, it's for chinese market i guess, particular version of dual sim model. Now, i've two sim, the operator is "3 italia", and its signal is from 3g to 4g (if the area is covered by 2g signal only, i go in roaming signal, and can't surf etc). Now, i'm looking for a dual sim phone, and both sim have to get at least 3g signal at the same time. I'm not asking to surf with both sim at the same time, and i'm not asking "dual active", not interested if when i call, the other sim goes airplane mode. I'm asking if Sony Xperia Z3 model d6683 has two sim can get both at least in 3g mode during standby and always in general, cause i surf with one sim, i call with the other one, but this last don't want to go roaming all the time. Hope it's clear.
I can get this particular model because an Eshop has it online, but first need to know this problem.
Hope it can, and battery can last in any case.
Or if you know some other phones...
Thanks
None has it?
Help please, if you know this model can do what im looking for, or just another phone..
Thanks
Bro i also have D6683 in which one sim will work as 4G and other as 2G.
Hope i have helped you

So the second one can't get higher than 2g? Are you sure, could be the operator..or is just the phone? And if you put sim 1 to 3g, the second always max 2g?
Thanks a lot, some people told me this phone could be the only one to do what i'm looking for, but i guess it doesn't exist.

D6683 is designed specifically for the Chinese market. It uses bands that are incompatible with rest of the world, therefore, it would be mostly useless anywhere else.
The following is from xperiablog.net:
Sony Xperia Z3 Dual TD (D6683) network support
– Dual SIM version which supports TD-LTE in China
– 4G FDD LTE: Band 1 (2100), Band 3 (1800), Band 7 (2600)
– 4G TD-LTE: Band 28 (2600 CMCC),Band 39 (1900), Band 40 (2300), Band 41 (2600 Unicom)

Fdd are here in europe, my operator cover 1800 and 2600 lte. Maybe Tdd too.
But could be enough the fact to support just 3g, but the important would be both sim can get up to that at the same time. I'm just asking this.

The only way to make sure is to test it. When I went to China last month my Z3 Dual worked nicely on Unicom's 2600 band. The first time I've read about D6683, I've got really excited until I've found out that it does not support bands used on North American continent wich makes is useless as a world phone to me. If you plan to use it in Europe only, there is a chance that it will work for you. I was not able to find out what 3G bands D6683 supports because the situation there is quite messy. Chinese 3G network is 80% incompatible for rest of the world, the only network that works with foreign phones is Unicom. It's very similar in Japan as well. Understanding that this phone is targeted for the Chinese market, I am pretty sure that it would be useless in North America (and most likely in Europe as well) on 3G bands. Luckily, with the proliferation of LTE networks while 2G is being slowly phased out, we are going to see more phones supporting simultaneous LTE on both SIMs soon.

Of course stay in Europe lol.
But i do not care the fact could not work here, as the fact I want it to support 3g at least at same time.
I guess user niks answerd the question, but i asked to check a few things via mp. But probaly he's right, the phone could show if, after you set connection on sim 1, could support 3g signal on second one. It's impossibile, i have to admit

Thank you. Maybe we re not understanding each other.
I think it can support 3g and even 4g here. My question is when one sim is on 3g/4g,the other one goes 3g? Not to connect data to surf, just about quality, frequency.. at least..
I'm looking one phone it can do it. Seems does not exist.

I do understand what you mean. It would have to be tested, however, there is a very good chance that it might since D6683 can simultaneously run on LTE bands using both SIMs which no Z3 Dual (D6633) can do. Most of the networks in Canada where I live use 3G for voice (same in Australia) and regular Z3 Dual is useless in such scenario, however, there is a chance it would work fine with D6683 which would become a dual SIM phone to go to except LTE bands.
Hope it can. Maybe will buy one to test it,directly.
Ok, Sony America and Sony China say it can't, as user niks wrote.
A Shop wrote on the sony z3 product crearly it can.
Will write to that Shop and to sony hong kong for the last time.
I don't know where to find my D6683 stock rom HELPPPP...!!!

I'm in the UK,
Will a Phone SIM from Three UK network work in the HUAWEI Honor X2 GEM-702L 4G ?
the reason I ask here rather than Three support is because those guys previously steered me wrong,
any advice appreciated before I order this phone from China, thanks guys.

In the UK the bands used are bands 1,3,7,8 and 20. The Gem-702L has bands 1,3,7 and 8 but not band 20. I'm pretty sure band 20 is the lower mhz (800 MHz) band for in building coverage (similar to T-Mobile's band 12 here in the US) You should get LTE just fine but in buildings where LTE coverage isn't the greatest you may only get 3G as the X2 doesn't utilize band 20 in the UK. From what I see for Three is that they use 2100mhz for 3G and 800mhz and 1800mhz for 4G. The X2 doesn't have 800mhz but has 1800 mhz so 4G should work.
Sorry. Posted on the wrong thread.
I am on Three in Austria here use "3" LTE 2600 and 1800 MHz perfect for Mediapad X2 703L and 702L,since the two have no Band20
But Three in UK use LTE Bands 1800 and 800MHz,only Mediapad X2 701L supports 800MHz (Band 20)
But LTE 800 is used only in rural areas and in the city the 1800MHz
Hiya, I'm on the 3 network in the uk, GEM 702L and I have no problem with 4g or any other network issues.
Bought the phone from 'Oxford Street' on amazon, not directly from china.
many thanks guys,
it turns out the phone I have ordered is the GEM 703L version, according to the Huawei web site it uses the following 4G bands
1800MHz (Band 3)
2100MHz (Band 1)
2600MHz (Band 7)
UK Three network uses 4G on
1800MHz (Band 3)
800MHz (Band 20)
and 3G on
2100MHz (Band 1)
it should be OK.
.
I can't seem to find the list of CA bands. I saw it before but can't seem to find it again.
FRD-L04 supports the following bands
GSM
850
900 (E-GSM)
1800 (DCS)
1900 (PCS)
UMTS
B1 (2100)
B2 (1900 PCS)

B4 (1700/2100 AWS 1)

B7 (2600)
B12 (700 ac)
B17 (700 bc)
and since its an LTE-A device, Carrier aggregation is possible.

Where did you get this information from? There's a site called FrequencyCheck claiming this, but it contradicts the information from Huawei/Honor - and Honor's live chat confirms it is incorrect. I'm not going to have my Honor 8 for a few weeks, but I sincerely hope this information is incorrect.
The official information (from https://store.hihonor.com/us/honor-8/specification ) is:

Interband CA: B2-B17,B5-B4,B5-B2,B2-B12,B2-B4 Intraband Continuous CA: B2
Given I plan to use this phone in the UK, I'm obviously seriously hoping that this is the correct set of info...

Oh. Got that info from that FrequencyCheck website only.
According to the Official website it has B8 and B20 in addition to the bands I mentioned in my post.
If confusion over sources is the problem, why not take a look at the FCC's tests? https://apps.fcc.gov/oetcf/eas/repo...id=RVnBofSaGkQDhYOqmiLX/A==&fcc_id=QISFRD-L04
The RFExposure document says that only the downlink of Release 10 CA is supported, with a max of two carriers. It does not have R10 uplink CA, ESC-FDMA or Uplink MIMO, or any other R10 features. Uplink comms are R8 specs. (Sect 1.3.3)
(7.1.17 has some more info on CA.)
In that same document, there's a power reduction specsheet showing the distribution of each band over various antennas. From there, it looks like these are the supported bands:
GSM:
- 850
- 1900
UMTS:
- II
- IV
- V
LTE:
- 2
- 4
- 5
- 7
- 12
- 17
(Sect 1.3.2)
Section 1.3 has a really clear listing, since it's the EUT (Equipment Under Test) Description. It lines up with the above information.
So @AllieKitty, the FCC doesn't mention anything about LTE/UMTS B1, B3, B8 or B20, not does it say GSM900 and GSM1800 are supported. It's possible they just didn't test those bands, since they aren't really used here, but I think they'd still be listed in the Device Configuration.

The FRD-L09 doesn't support bands 2, 4, and 12 though. Also, it costs a LOT more - got my L04 (in my friend's possession in the US right now) for $259.99 on Amazon.
As for the FCC... that means nothing... the L14 has the same FCC tests. ONLY bands used in the US get tested by the FCC. Which makes the band 7 tests odd, as band 7 isn't used in the US yet - but it is used in Canada. My understanding is that band 7 is a possibility for future use in the US, which is probably why this needed testing.
PS thanks for the FCC link, I found the correct list under the description of equipment in the RF test report:
FRD-L04 is subscriber equipment in the GSM/WCDMA/LTE system. The GSM frequency band includes GSM850 and
GSM900 and DCS1800 and PCS1900. The UMTS frequency band is B1 and B2 and B4 and B5 and B8. The LTE
frequency band is B1 and B2 and B3 and B4 and B5 and B7 and B8 and B12 and B17 and B20. But only GSM850 and
GSM1900MHz，UMTS frequency B2 and B4 and B5，LTE frequency B2 and B4 and B5 and B7 and B12 and B17
bands test data included in this report. The Mobile Phone implements such functions as RF signal receiving
/transmitting, LTE/HSPA/UMTS and GSM/GPRS/EDGE protocol processing, voice, video MMS service, GPS, AGPS,
NFC and WIFI etc. Externally it provides one micro SD card interface (it can also used as SIM card interface),
earphone port (to provide voice service) and one SIM card interface. FRD-L04 is single SIM smart phone. It also
provides Bluetooth module to synchronize data between a PC and the phone, or to use the built-in modem of the phone
to access the Internet with a PC, or to exchange data with other Bluetooth devices.

Me too! The band 7 testing is odd. Those frequencies are used in the US for TD-LTE (as band 41). Band 7 is a theoretical possibility from my understanding but unlikely. Sprint would be in the best position to try to get their spectrum paired to use as band 7, but why? TD-LTE offers benefits FDD-LTE doesn't in efficiency. Canada uses B7 tho, so that may explain it.
Anyway, to reiterate for OP's sake in case it got lost in the crowd:
Interband CA: B2-B17,B5-B4,B5-B2,B2-B12,B2-B4 Intraband Continuous CA: B2
I have confirmed EU-version (FRD-L09) CA Combos: https://cacombos.com/device?model=FRD-L09 - only Contiguous CA seems support.
Does the XT1541 model supports the following network frequency range?
LTE (4G)
FDD band 3 (1700~1800 MHz)
FDD band 8 (900~960 MHz)
I have checked gsmarena.com/motorola_moto_g_(3rd_gen)-7247.php though I prefer to be 110 % sure.

The XT1541 supports LTE Bands 1, 3, 7, 8, and 20, according to multiple sources... all we are going to do is Google it just like you, but when all sources agree I don't think there is much chance it is wrong.
FrequencyCheck, GSM Arena, and Wikipedia all agree... If you are still in doubt, use https://willmyphonework.net/ and check your specific situation.
