[Q] Will this work on Three's 3G network?

I am thinking about buying this phone, I am on a contract with Three so want to use that sim. Can I use that sim in this phone as I am concerned about the different bands, according to GSMArena the LTE version does not have the 1900mhz band. What band does Three use for it's 3G? It's all very confusing and I want to know before I purchase. I heard from somewhere it uses the 2100mhz band, which will be ok.
Many thanks!

3 uses 1800 for 2G and 2100 for 3G. Both of which are supported by both varients of the S3.

Lost Reception+Data Connection on Rogers Network

Hey guys
I got XZ C6603 today from handtec. I activated brand new LTE simcard at rogers store and set up lte apn.
Soon as I did that data connection rapidly changing from h+ to 3g for a while then drop the data connection and phone reception as well.
Seems like lot of ppl here in Canada having trouble getting LTE connection but I am having hard time getting my phone reception and H+ connection.
I'm not sure either XZ is defect or this phone is simply wont work with Rogers.
Any solutions?? or should I just return the phone back to handtec?

LTE doesn't seem to work with the Z on Rogers.
Go into network settings and network mode and change it to only WCDMA(preferred)/GSM.
3G and HSPA+ work flawlessly so keep it on those instead.
Basically the phone keeps searching for an LTE network but can't connect so it'll keep switching between the network modes.
I'm hoping there's a solution to this soon, because the Z can actually find the Rogers LTE network but can't connect for some reason.
Probably a work around fix that can be done. :good:

HSPA+ will probably be unpredictable on a regional basis - many North American carriers use UMTS1900 and the 6603 does not support that band for HSPA+ operation.
6603 will not operate on LTE in any band in North America I'm aware of.

You are wrong,
Rogers does support LTE 2600

I would not use a phone on Rogers that can't get 1900Mhz but ... You should be able to use 2600 LTE. Have you entered the LTE APN ?

HSPA+ works fine where I am on my 6603.
People have been able to get LTE on theirs as well, depending on the region.

My LTE worked for an hour the other. I've read the 2600 band is a higher speed band, but it has weaker penetration and more sensitive.
Im beginning to think that you need both 2100 and 2600 bands for LTE to properly work in Canada since Rogers have both deployed simultaneously. Maybe Rogers need to improve their 2600 deployement in order for the XZ to work.

You need band 4 and band 10. Each frequency is used for different reasons (upstream/downstream). Just having 2,600 Mhz won't do anything. It's already been confirmed by multiple users that LTE doesn't work in North America (AT&T, Rogers, etc.)
That's why the C6603 wasn't released in North America.
The leaked C6606 model should support it, as well as the ZL. (http://playstation.com/psm/certified.html)

Then how does the optimus g on rogers use lte 2600? The optimus g 2600 on rogers only have lte band 700/2600 according to rogers website. This is the first carrier phone to use the 2600 network I believe

Because it uses 2,600 Mhz (band 7) for the downlink and 1,700 Mhz (band 4) for the uplink (even though it doesn't list it in the specs).
(Going into the Service Menu on the Optimus G shows off its full band support.)
Without the appropriate uplink AND downlink support, LTE will not work.
Rogers has LTE deployed on bands 4, 7, and 10.
The C6603 supports bands 1, 3, 5, 7, 8, and 20.

Hi, can you tell me how to get the lte band menu?

Has anyone tried enabling bands with QPST?

I have a question for all the lucky ones of you who have a Mi Mix.
With most of the Xiaomi phones which are released, people are unhappy about the lack of band support for regions outside of China. I know many people in Europe are unhappy about not having Band 20, those of us in Japan would really like to have UMTS Band 6/19 (among others), Australians want LTE Band 28, and people in the US would like Band 12/17.
As you may know, with some phones, it's possible to unlock these bands by putting the phone into diag mode and using Qualcomm tools like QPST. Here in Japan, it was possible to enable the UMTS Bands 6 and 19 on the Mi5 and the Mi Max, but not possible on the Redmi Note 3 or the Mi5S, so it's really case by case.
Seeing as that the Mi Mix is a concept phone people are crazy about all over the world, I am very curious whether it's possible to enable LTE bands and WCMDA bands on the Mi Mix. I don't want to spend the big money to buy one without first having confidence that I can get it to work on my carrier's bands.
So I'd like to start this discussion. Has anyone tried anything? Successes, failures, please post them all!

This (QPST) is something I have no experience with,but,interested in the subject:
I'm good with the band support (for now) as what's available in my area,with my carrier,is supported (Bands 2 &4 on T-Mobile US,no Band 12 or 66 yet),definitely would be nice for at least Band 12,if possible,as I believe my area will get it eventually.
One side note & a positive one at that:
My MiMix locks-in on a signal & has better/stronger connections than any phone I've used to date. This was really noticeable while commuting back & forth to work today,unbelieveable signal quality.
IDK if the ceramic body is better vs other materials,but,recent flagships from HTC/Samsung/LG pale in comparison vs this phone.

i have MI MIX in hand.
I think we need MIX Diag Driver to make it recognize from pc. MI5 Diag drivers are not the same

I've heard the Mi5 diag drivers were usable on the Mi5S, which is the same SD 821, so that's strange. What happens when you put it in diag mode and plug it in? Can I see a screenshot from device manager, or some evidence of what the device is?

I've got one in hand in the states (where I actually do need to unlock band 12 for T-mobile) and a patch cable I made handy in case this thing goes brick mode from us trying stuff, I'm game to be the guinea pig for science.
Fair warning though, while I'm a web developer that's very comfy with terminal, I'm new to the android ADB world, so pretty detailed instructions / links to guides will be needed ha!

Good luck Ken, I hope you are able to crack this bad boy.

Is that band 4 only on LTE? I've seen many spec sheets and the carrier I'm on only has band 4 for 3g.

this is what I have gathered from various sources (so yes Band 4 is both LTE and 3g)
Tmobile
LTE Frequencies:
1700 MHz & 2100 MHz AWS band 4
1900 MHz PCS band 2
Lower 700 MHz band 12
3G/4G Frequencies (WCDMA):
1700 MHz & 2100 MHz AWS band 4
1900 MHz PCS band 2
2G Frequencies (GSM/GPRS/EDGE):
1900 MHz PCS band 2
ATT
AT&T 4G HSPA and HSPA+ use 850Mhz(Band 5) and 1900Mhz(Band 2) bands
LTE uses Band 17(700Mhz), Band 5(850Mhz), Band 2(1900Mhz),
Band 4(1700/2100Mhz)
LTE B29 (700)
LTE B30 (2300 WCS)

Yes....was just giving the bands and frequencies I know for two GSM carriers in the US. Monitoring the bands at various locations by something like signal check lite (much easier to use/read than lte discovery IMO) would be only way to tell.. If I recall correctly this device has 3g at 850,900,1800,1900 so there is no band 4 on 3g it seems... Although band 4 (1700/2100) COULD be a 3g band too for some devices. Someone with better knowledge can chime in here. I might be wrong.

Update: I have actually successfully forced band twelve with NV values (I can see it stick and unwind the value to see that band 12 is allowed after a reboot). I followed about 10 diff guides to get my bearing on working with the Qualcomm editors and maintenance programs.
Sad to say: the modem in the Mix simply won't do band 12. I talked with a few folks from the Xiaomi Reddit Discord and they confirmed my suspicions that with Xiaomi (with a few exceptions) it is usually hardware that's keeping you off of a band.
I don't personally think there's any amount of software hackery we can do to get bands unlocked.
Edit: I am quite comfortable in ADB / SU and am happy to try any and all suggestions out on my phone in addition to what I've tried already btw. Please do let me know if there's something you think I may have missed following the various unlock threads.

Sorry to hear that the band could not be tapped into...
yes most likely a hardware thing-like Samsung (some of their models exclusively for Latin america have u.s bands but the 'international' variants of the same models will not do the U.S bands no matter what...
I actually opened one of them (got a damaged T239M) and found indeed that the motherboard is different...(so much speculation and folks asking/trying to flash S. American firmware on like the T705, T239 etc, myself included (not possible anyway even if going through TWRP and flashing modem files etc...bootloader and pit all different..so nothing would change with the other parts of the firmware)
so it is highly likely in this case that the modem will not do bands 12, 17 (ATT) and 29, 30 (ATT). However, it is impressive that for a China phone this will even do bands 2, 4 and 5. Huawei models (again supposedly international) except for some variants of the smaller 5-5.2 inch models (not p9, p8, P8 max, x2, t3, t3 pro, or m3 (some of these are the tablet phone types) and numerous other Chinese phones will not do anything more than 1, 3, 7 and then maybe 8 and 20 or a 28. (all useless for North America). Huawei has an M2 variant that has US bands and also on their smaller phones (certain versions)
so for the Mix, you at least have LTE 2, 4 and 5 (though of lesser importance).

So far my experience is that if the band isn't listed in those spec sheet it isn't there in the hardware (apparently a very Xiaomi thing to do). I'm finding that they rarely software lock you out of the bands, it's usually that their hardware simply doesn't support the band.

Will the A3010 work well in Europe?

I'm about to buy a OnePlus 3T.
I live in Sweden and travel in Europe from time to time.
Will the A3010 work well for me (even with 4G)?
I have already looked at willmyphonework.net/ but it only says:
"Device is compatible with some of the network carriers frequencies. It may work."
What practical advantages would I notice with a A3003(European version) vs the A3010(China version)?

The main difference between OnePlus 3T A3003 and A3010 is the A3003 supports LTE band 1/3/5/7/8/20/38/40, which is the international model while A3010 supports LTE band 1/3/5/7/8/38/39/40/41, which is the China model.
basically you wont have support for this bands on 4G

The only LTE band that is missing on A3010 is Band20. Most of Sweden network carriers are using Band7 so you are good to go. When you go aboard is a different story. But you are also more flexible because you can chose the roaming network. All you have to do is to chose a supported network carrier.

I'm confused by this. By those numbers it seems that the China model covers all the numbers as the Europe mode,l plus a few more. If so, then what bands are missing?
Or doesn't it work that way? Please help me understand
Edit: Oh... I missed to see band 20. But what does it mean practically that the China model misses band 20? How will I notice it?

On a network that is using Band20 you'll have only HSDPA connectivity. Basically the phone will work just fine except the fact you won't have LTE connectivity. You'd have only 2G/3G/H+

Thank you. It's getting somewhat clearer. Okay, but how likely am I to run in to Band20? Is that band (the only one missing from China model) more likely to be used than any of all of the other bands that are listed?

I'll give you the UK example. In UK there's 3 LTE bands in use: 3,7 and 20. Other put 2600Mhz, 1800Mhz and 800Mhz (that's Band20 btw...). Only O2 is using only Band 20. All other providers are using at least one extra LTE band. EE is using all three LTE bands, Vodafone is using band 3 and band 20 and Three is using band 7 and band 20.
Now here is the thing... Those network checkers are telling that your device might work. But is not always the case. Here is the Vodafone UK example. As I said they are using Band 3 and Band 20. Now let's take a phone with Band3 but not Band 20 (for example my former Xiaomi Mi5). Will work on LTE but only in urban areas. Why? Because in rural areas the band used are band 7 and 20. Why? Lower frequencies are better at travelling long distances so are more suitable for rural areas where there are fewer masts. Also Band 20 provide better indoor coverage. But if you live in an urban area Band 3 and 7 are more likely to be used. The higher the frequency means higher capacity and therefore the ability to deal with more users which is a must in an urban area.
All in all the best way is to call your provider and ask what frequency they are using in YOUR area. If they are using 1800Mhz or 2600Mhz you are good to go. If not...I'm sorry.

Just for my curiosity why are interested on a China version and not on a Europe one?

Here is the list of LTE bands used by Sweden network carriers. Take a look at it and you'll see if China version is good to go on your provider.

If you're primarily going to use it in Sweden, I would go with the A3003 (that's what I did, but then I seldom leave Jämtland ?).

Wow. Now that was a good response! You really seem to know your stuff! Cool. :good:
Okay. Now I understand things a lot better too.
I use Telenor (and spend quite some time in Jämtland (rural) like another poster here:good.
Well I plan to buy my phone on ebay and the annoying thing is that the A3003 is about $100 more expensive than the A3010. I still think it is hard to decide if it will be worth an extra $100 for the Europe version...

You should not only consider LTE Bands, but also consider LTE CA.
Hong Kong/ Europe Model (A3003)
FDD-LTE/ 4G: Bands 1/3/5/7/8/20
TDD-LTE/ 4G: Bands 38/40
LTE CA / 4G+:
B3+B7, B3+B8, B3+B20, B7+B20, B3+B3, B3C, B7+B7, B7C, B40C
China Model (A3010)
FDD-LTE/ 4G : Bands 1/3/5/7/8
TDD-LTE/ 4G: Bands 38/39/40/41
LTE CA/ 4G+:
B1+B3, B39+B41, B39C, B40C, B41+B41, B41C，B38C
American Model (A3000)
FDD-LTE: Bands 1/2/4/5/7/8/12/17/30
LTE CA/ 4G+:
B2+B12, B2+B17, B4+B7, B4+B17, B12+B30,B2+B2, B2C, B4+B4, B4+B12, B4+B5, B2+B5

Ok. I ended up buying the EU-version as I found one that was just $40 more expensive.
Many thanks for making this more understandable guys! *thumbs up*

India 3T - 4G/LTE not working in US

Hi,
I bought an one plus 3T in india and brought it to US. I'm getting only E not even 3G. When I enquired in T mobile/lyca store, i was told that india unlocked mobile won't support the US bands. Network upgraded. It was big surprise to me. Please suggest me how to unblock additional LTE bands in my 3T mobile.

That's not possible, you should trade your 3t A3003 for a 3t A3000 American band-unlocked model.
Check the specifications for each model under connectivity.
https://oneplus.net/us/3t/specs

Wait, what?
I live in Sri Lanka (Tiny country below India) and my 3T is the Indian device. I toured Europe for 2 weeks, and I used an O2 Sim, and used LTE in Europe for the whole time I was there. Have you tried going to Settings, and selecting "LTE/3G Only"? That may fix your issue.
I swear, there should be no issue with the bands.

India uses FDD 850, 1800 and TDD 2400. Most of the Europe uses TDD 1800. So you getting LTE in Europe is not a surprise.
USA uses 700, 1700, 1900, 2100, 2300
Varies with MSP
You will at least get 3G with T-Mobile and AT&T

Europe and india uses the same bands. I lived in uk and used the uk phones in india and indian phones over there. Its the states that uses different frequencies so most of phones don't work properly outside states.

Ah, thanks for clearing that up for me. I had no clue that it uses the same bands.

Compatibility of phones with the cell networks in the US are a total pain in the you-know-what. We have 4 different major carriers, all using different bands (a little bit of band sharing, but most completely different) for 3G and LTE (GSM is a little more standardized thankfully). Basically, as a general rule if a device not intended/designed to work on US (and depends on which exact US carrier), you are probably going to run into some incompatibilities (no 3G or no LTE, or limited connectivity).

Talk about synchronicity eh? But do the difference in bands give any speed differences, or call clarity? In the blind about these stuff, coming from a country that has only one carrier out of five who is still beta testing VoLTE.

Not an expert, and had to Google that. From what I'm reading, lower frequency (MHz) has better penetration (through buildings, etc.) while higher frequency bands have higher data capacity.

There are steps on how to unlock additional bands. There are like 50 steps. I dont remember where I've seen it but if you google how to unlock bands on OnePlus you will find it. Also try to flash Oxygen OS from US web site which I see no reason to work but just a suggestion lol

There are no region specific versions of OxygenOS, so this will do nothing but reflash the latest update.

There are no steps at all. You cannot "unlock" bands, as they're hardware related. There's no way to switch bands out of the blue.

No you can't switch but you can unlock some bands which might help

At one time that was true. But for Qualcomm SoCs, the band support stopped being set in hardware (at least for the most part) some 3 years ago with Snapdragon 801 (or maybe earlier, but definitely with 801). Support for all or most bands (might be some exceptions) used worldwide is there, but the specific bands are enabled in firmware.
https://www.qualcomm.com/products/rf
That said, enabling bands is a long process as noted; and has the risk of resulting in a radio brick. So it's best to buy the correct region version OP3T (which supports the needed bands out of the box) when possible.

Why aren't all bands just enabled by default then? I don't understand why there are different models for different regions.
I have a US OP3T and I'm visiting India. It''s working with Jio in India (although it supports only only of the 3 bands used by Jio) but VoLTE doesn't work for some reason.
