jiayu g2 - General Questions and Answers

Purchased a Jiayu g2 to play with so far the phone is very nice. It is suppose to work with 850/900/1900/2100mhz wcdma however I cannot get it to work on 3g with att I only get edge and have tried just about every apn setting I can. Does anyone else in the US have this phone working on 3g? I have it rooted. Funny never thought I would say this but it is a very nice phone.

A lot of these Chinese phones state they're quadband GSM, but only have 2100 for 3G. Correct me if I am wrong.
Also, do you accidentally have GSM Only set?

here is the link for google translate.

this is the manufactures website and in the product parameters tab it shows 850/900/1900/2100 wcdma 3g and even in the engineermode menu it has them listed. i only paid 160 for it but to be honest it is a real nice phone and i was completely shocked at how well it was constructed. i even have it rooted. if there is anyone else out there that has this phone in the US or anywhere i would be interested to find out what bands you are on.

Take a look at the specshere
It shows 2100MHz for 3G
Don't be fooled by Engineering mode. It may show the options for specific MHz, but if the phone doesn't support it then the options pointless and misleading.

i hear what you are saying. but the fact that the manufacture website shows the bands. i understand that the selling sites are all diff some show 2100 some show 850/2100. but for 160 it was worth a shot.

So no one else in north America has this phone?

Hi,
I have heard that MTK6575 SoC does support 3G on 850MHz/1900MHz. Two things might prevent it from working.
1. Your cellular provider maynot be providing 3G on both 850 and 1900 where you live. It could just be on 1900MHz where you live. Could you go to some other part of the city and test it?
2. I have read that the antennae required for 850/1900MHz is different from 2100MHz. So, even if the SoC supports it, the signal strength is not strong enough to make it work.
I would be very interested in your test results since I am thinking of buying one.

Hi! Did you insert your 3G SIM on the SIM 1 slot? It is the only SIM slot capable of 3G (WCDMA). There are two slots in Jiayu G2 and only SIM 1 will work with 3G. SIM 2 is for GSM only.

yes i did. i have even tried to get help from Ejiayu.com and no one replies. the spec on the their website show is is 850/900/1900/2100 mhz wdma and it shows in the engineering menu as well but i think it is a lie i can not get it to work at all in 3g. My sim works fine in my Pantech Burst 4g LTE. i have not given u completely but i need someone who has an in depth knowledge of this phone to help

I actually rooted my Inspire, loaded the Euro DHD ROM and tried it on T-Mobile this morning. It worked, but no 3G, much less 4G.
So what would need to be done to get that type of thing to work fully? Something with the baseband or something right?
Sent from my HTC Vision using XDA App
It can't be done, the hardware is different, you won't get anything better that edge
i really need my inspire unlocked?
just wait a few months, the htc incredible S is supposed to coming to Tmobile and that device has same specs as the inspire except smaller screen and has FFC.
Unlock it and you're good to go! That is, if you don't care for 3G/4G
The Inspire's 3G radio is incompatible with the bands used by T-Mobile unfortunately
i want the big screen though lol. I have a g2 right now and I'm really just craving one of those huge screens. What about the Desire HD? would that work on TMO? or is there any other options out there?

your option is an hd2 on android
I don't get it. One of the reason I pick Inspire because it has the same 2G/3G band frequency like the Desire Z (G2). If Desire Z works then why not the Inspire?
Quote from GSMArena:
HTC Desire Z
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 900 / 2100, HSDPA 850 / 1900 - North America
HTC Inspire 4G
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 1900
Even the Incredible S is not 1700 band
HTC Incredible S
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 900 / 2100
The desire z looks like it does not work on t-mobile either. T-mobile needs 1700/2100 for 3g, which are not listed in the specs yet posted.
Can I use T-Mobile 3G devices on another carrier’s 3G networks?
You will not be able to roam with your T-Mobile 3G device on another carrier's 3G network. T-Mobile devices use the 1700Mhz/2100Mhz frequency band (for 3G) and it is specific to T-Mobile. You can however roam on another carrier's 1900Mhz frequency band using GSM. Likewise, another carrier’s 3G devices will not be able to roam on our 3G network.

But his question is specifically asking to use 3g on other carriers. Which the answer is no, even rooting won't help. It's a hardware limitation.
its something i have thought bout but why would you pay that much for a phone tht will only run on the Edge. Wait for the Pyramid to come out or get a Desire HD from ebay. its just the European version and has the bands ability. or like what has been mentioned before about the HD2 and load it with Android. Thats what Im using which is awesome becasue you can use the HSDPA speeds and 3G speeds and have that huge 4.3 inch display and still have a 1ghz snapdragon processor.. another awesome thing about it is that there is SOOO many roms you can load to customize your phone like if you wanted the basic Sense Rom like the inspire or the Evo there are plenty of roms for it, if yo wanted the MyTouch 4G rom then you can load it, if you wanted a Nexus Rom then you can load it, and its much faster with updates so you can even have Gingerbread already on your phone and they are even already gettting the bugs worked out of having Honeycomb on the good ole HD2. its overall a very under rated phone but thats because it had tons of issues with WinMo 6.5 but with ANdroid loaded on it I havent had problem one with it.. Im sure others have thier opinion but thats mine for it.. hopefully any info helps...

AT&T to Buy T-Mobile for $39 Billion USD
AT&T to Buy T-Mobile for $39 Billion USD
T-Mobile 3G (i think 4G also) Phones Will Require Replacement After AT&T Merger
SO buying this phone and unlocking it will give u a little while to use T-Mobiles services (maybe 2 years AT MOST) after that u will need an AT&T phone
but the trade off to being able to use T-Mobile for a while is that u will be at slower speeds for a while BEFORE AT&T destroys this grate service provider
can you say "Cingular" ?
so this is the best GSM phone as it will be merger proof !!
Internet settings?
hey guys i realize this is an older post but i rooted and unlocked my htc inspire and put in a Tmobile sim card and calls work fine and text messages too the phone automatically detected apn and everything but i cant get it to connect to the internet what should i do is there a way to set to 2g networks only? is that even required?

[Q] Samsung Vibrant 4G SPECIFICATIONS

I know the original vibrant was a pentaband phone, supporting AT&T's 850/1900 networks as well as t-mobiles 3g networks....
Can anyone confirm the 3g bands on the new Vibrant 4g?
Will there be fast 3g 21mbps for 850/1900 on the modem chip also? ( or 4g whatever you want to call it, in my book its just faster 3g..)
someone enter the debug screen and check which bands are available...
cheers!

HSPA+ 21 only works with T-mobile, AT&T doesn't use an AWS band, in this case is 1700/2100Mhz.
Someone may have been able to 'trick' the vibrant into using a basic UMTS band on AT&T, but I never heard of it, let alone heard that the Vibrant supported AT&T 3G. The Vibrant has GSM.support for them (2G), I haven't seen anything else.
Where's the supporting documents that people have been getting At&t 3G with a T-Mobile Vibrant?

Trust me.... I'm using a vibrant on at&t with 3g. It does support the wcdma 1900 band. There is alot of evidence of this...heck engadget made a post about this... google it!
Edit: What I was trying to ask is if the galaxy s 4g supports the 1900 wcdma that the original vibrant supported....

That would work....hopefully the galaxy s 4g can be unlocked the same way the previous galaxy s phones could.
In my research I have found that 4G is not backwards compatable with 3G. Someware I read that companys are putting 3G and 4G chips on the new 4G phones to bridge the gap between the 3G chip ability to handle voice and the 4G chip being able to handle data. I can't say for sure if SGS4G has both chips. It's a know issue that the 3G SGS misses calls when connected to a laptop because It does not handle data well in combination with voice. That's why I upgraded to the 4G. I don't think Its going to make a lot of difference until TM gets their HW in place with a backbone that can support it.
Samsung Galaxy S 4G 1900 MHz WCDMA
I bought my Samsung Galaxy S 4G at a T-Mobile store in San Francisco. I subsequently upgraded it to the latest firmware provided by T-Mobile using Samsung Kies.
I usually use WCDMA only mode because GSM causes awful buzzing sound when I use it in my car (I have a FM transmitter connected to my phone).
Anyways, I was curious to see if I'd see AT&T, so I searched for network (still under WCDMA Only mode), and it found both AT&T and T-Mobile.
I pressed *#197328640# in the dialer, and then went to the debug screen/band selection to look at available bands, and it actually does have 1900 WCDMA.
It shows
GSM 850, 900, 1800, 1900, WCDMA 2100 (FDD I), WCDMA 1700 (FDD IV), WCDMA 1900(FDD II).
I don't know if AT&T SIM would work since my phone is locked but I can report back once I get it unlocked.
EDIT: Reading an old post of mine, I realized that my memory played a bad trick on me. My tests DID work on 1900 WCDMA and DID NOT work on 850 WCDMA, just opposite to what I wrote earlier in this post. --sorry

I don't think it would work. For reference, here is a side by side band comparison between my Vibrant (tested 3G on AT&T) and my coworker's SGS 4G (locked, untested).
The essential band here is the 850 1900 WCDMA, but the "overflow" 850 WCDMA is missing and I couldn't make it work anyways (I'm in Houston, maybe it is not switched on here).
My understanding is that AT&T usually uses 1900MHz for 3G, and in certain cities where they don't have enough bandwidth in 1900 MHz like NYC and SF, they use 850MHz.. so you could still get by with only 1900 MHz, no?

Yep, thats what I have heard as well. Now one thing of note. When I tested my Vibe, it only worked on the 850 1900 WCDMA band. Could not make it work on the 850 no matter how hard I tried. I'm in Houston for that matter and maybe this 850 WCDMA is not enabled here.

I'm currently unlocked on AT&T and i'm on 3G. I ALWAYS have an issue with upload speeds, but otherwise download speeds are just fine.
I attached four photos, of the available bands with my CURRENT galaxy S 4G unlocked on AT&T.
Also, a speed test I ran. That download speed is WAY higher than average because it was taken when the network was under the lightest usage possible, late at night.
Oh wow, over 5Mbps download on AT&T?
Are you on AT&T's 4G (HSPA+) or 3G?
I'm supposedly on T-Mobile 4G (my phone shows 4G when I download/upload), but I don't ever get 5Mbps. I get usually something around 2~3Mbps down and 1Mbps upload. I'm in the Bay Area.
I went into phone debug page, and one of the screens says HSDPA[0], HSUPA[0]. It also says network status: HSDPA (sorry I don't have the exact info on me right now).
Am I really just on HSDPA, not HSPA+? Is there a definite way to find out what my phone is using? Thank you.

Technically I'm on HSPA+, though this phone doesn't even cover all of the "necessary" bands.
Look, to edit what bands you're on go into the market and download SGS Tools.
Then, go into the first line (Secret Codes) and hit Band Selection.
I'm on AT&T so I'm not sure what bands you need, but you can manually select them in there.
To check the band you're on, go to GSM Status in the "Secret Codes" page again.

Oh I know I'm on 1700/2100 MHz because that's the only frequency (AWS) that T-Mobile uses for WCDMA/UMTS/4G/3G.
I downloaded Phono, and it says Network Type is HSDPA. Shouldn't it say HSPA+? I'm just wondering if there's an easy way to tell if I'm really on 4G (aka HSPA+) as opposed to 3G.
I actually messed around with debug settings last night so I'm worried that I screwed it up....

Which debug settings did you change?
And as for Phono (which I've never even heard of/used until now), my phone says HSDPA as well, which, quite frankly, makes no sense. I guess you can technically get speeds of around 5MBPS on HSDPA but it's not typical.
You should easily be able to tell whether you're on HSDPA or HSPA+ with the 4G/3G connectivity icon. in your status bar.
Now, I'm no expert, but hopefully that answers your question.
I played around with GCF settings. When I go into debug mode, there was something about choosing Rel.6 or Rel.5 or cancel settings.. And then also, if you do *#3214789#, you can enable/disable GCF Mode.. which I have no idea what it is about....
Thanks!

Hmm...that's awfully strange.....
I can't find anything about it anywhere....
Try restoring using ODIN yet?
I mean, if the phone is that messed up since you messed with that setting.
I put my friends att sim in my unlocked sgs4g to test and the 3g sign came up by the bars as well as the att operator logo didn't really test out speeds but im guessing that the 3g sign wouldn't have came up unless it was really picking up that frequency.

Will the T-mobile version work on AT&T?

The Tmobile version looks like it has the 850/1900 bands to work on ATT's network? Does it in practice?
I know one problem might be the micro sim card idk if att uses those at all. I guesse u could probably just cut a regular one

I agree the att one x will have the same awesome krait prossecor and it might have the same internals maybe making it possible to flash one s roms with the art one x. Because the att one x and international one x won't be able to flash each others Roms

ATT uses micro sim, that's not an issue.
Frankly I find these LTE just getting to be ridiculously big. The HTC One S is the perfect size imo.
According to the FCC document for the t-mobile version, it's supports WCDMA 850 (ATT), 1700 (T-mobile) and 1900 (ATT,T-mobile). So I should fine on ATT's network as long as I put in the correct APN right?
Also looking for clarification on this...
It probably will, but it has to be unlocked and for that to happen, we need S-Off which could very well be a few months away. Why don't you buy the international, unlocked version outright? You also get your choice of colors (red/black as well instead of just blue/grey).
Wow, not a straight answer yet, YES and unlocked HTC One S will work on ATT 3G (1900mhz). No ATT LTE support. Contrary to above micro-sim is not a problem, att iphones use them and of course you can always cut it as well.

p.s. that band might not be available on some areas and 4g might not work, but works where i live (boulder,co)
Ok so... the T-mobile version will work with AT&T... will the international version work any less? As far as I can tell they both use the same bands (with exception to AWS of course).. but I very well could be missing something.

i am sure it works with att hspa plus. i have persoanlly tried unlocking and using it and it works plus check this video: http://www.youtube.com/watch?v=odaS8tcxa0A this dude does the same thing and you can see it working on att along with the galaxy note
p.s. that band might not be available on some areas and 4g might not work, but works where i live (boulder,co)

I unlocked it through ebay. just search in ebay "htc one s unlock" its about 8USD. you pay and then you leave a message with your IMEI number
I unlocked mine by calling T Mobile and asking nicely. I popped in my ATT SIM and got HSPA plus nicely. It works perfectly on ATT

I live in India where I can't get it
Can I try Cellunlocker.net
There it is for $10
I thought it had the 850 band for 3G only. I don't see any specs that say it has the 1900 band for 3G. This tells me it will only work in places that AT&T has 3G on the 850 band. Does ATT use 1900 at all for 3G?

ATT uses 1900, in some markets, ATT uses the mixture of both, 850 has better penetration in urban areas (tall buildings ...)
I'm interested in the phone, but i'm going to be using it on ATT. Can somebody that has the device tell us what is the FCC ID?
Quick trip to Phone Scoop website, i can see that there are two FCC ID's associated with the phone. NM8PJ40110 passed the tests using ATT WCDMA bands (band II 1900 and band V 850) and T-Mobile bands (band IV 1700/2100). NM8PJ40100 passed only ATT bands. Both doesn't show any reference to any test on WCDMA 2100 (band I), which probably means that the phone doesn't support the international 3G band.
In short, theoretically, the T-Mobile's version of HTC One S should work on ATT 3G bands (WCDMA band II and WCDMA band V), however, the phone would not support ATT LTE.
Since the hardware is there (FCC website proves it, unless if the official T-Mobile USA version got pushed with different FCC ID that i do not know), the phone should work on ATT 3G, but nothing prevents T-Mobile to disable the ATT 3G radios in their ROM. I think that S-OFF would give opportunity to enable the ATT radios (if they are blocked)
We will see ...
Take care,
From my experience, the ATT radio is not blocked and works fine.

Verizon GS3 "World", "GSM", or ???

The GS3 Verizon is a CDMA device. Supposedly it has GSM compatible radios too. It's supposed to be able to work on GSM networks after a software update coming soon. Does this thing have a sim card slot? I don't see how it would work on GSM networks without it. Does anyone know how this works?
I'm hoping to use it on Verizon in USA, but on Telcel while in Mexico BUT with my Telcel sim. I realize my hopes are slim but if there's a sim card slot maybe it's possible???
Thanks.

It has a SIM card slot for the LTE. Unsure about compatibility though.

Actually, I have an old Verizon Motorola Z6c World Phone here that I bought in 2008. It has a Verizon sim card inside.
Z6c Specs say:
2G Network GSM 900 / 1800
3G Network CDMA 1xEVDO (800 / 1900 MHz)
Anyway, there's no LTE involved on the Z6c back then. SO apparently the GS3 will need the sim on non CDMA networks. I just wonder if the software experts here can make it possible to use the sim only at certain times and at the same time unlock the phone.
A lot to ask but will be a huge feature if done.

I said earlier that I wasn't sure about compatibility, but I'm starting to believe that this is not possible, as the Verizon version lacks the proper GSM/HSPA+ radios. There's a model comparison chart that you can expand on the Wikipedia page. Software probably won't be able to pull the miracle you're asking for. Sorry

Maybe this will help? http://androidcommunity.com/verizon-may-enable-global-roaming-on-lte-phones-soon-20120518/ from what I gather LTE is based off of GSM and its just a matter of unlocking the GSM bands on the phones.

The SCH-i535 did recieve GSM certification for bands 850 and 1900. No HSPA+ though.

Yeah, I don't think the current specs out on the GS3 are totally complete. If the phone is admittedly needing a software update to allow the GSM roaming then they can't just put those bands in the specs with no caveats.

Does this unlocked LG G2 from Expansys work with AT&T LTE?

Please help me check out this http://www.expansys-usa.com/lg-g2-smartphone-32gb-black-unlocked-255286/? I'm looking to get it to use with AT&T. The specs doesn't talk about AT&T nor LTE. $499.99 is a great price if it can work with AT&T LTE. Thanks

It says D802 right on the page, so use that to see how it'll work on ATT.
Don't think D802 will work well on AT&T.. Doesn't have the 700MHz frequency which is the main LTE one on AT&T.. Should have no issues at all on T Mobile LTE..

If you aren't hung up on new, check out your local craigslist for a Verizon branded G2. They are usually listed pretty cheap where I am at (in the $225-325 range on average in excellent condition). They are unlocked, you can flash AT&T firmware on it, LTE works and best of all it has wireless charging built in as a bonus. I have been very happy with mine.
It says under Technical Details:
Network: 4G: 800/900/1800/2100/2600 MHz / 3G: 850/900/1900/2100 MHz / GSM: 850/900/1800/1900 MHz
So on AT&T you'll get 3G only. It's missing the 700 (primarily) and 1700 MHz (a few markets) bands for 4G.
On T-Mobile you'd get 2G and 3G only where T-Mobile has refarmed the 1700 MHz spectrum for LTE and moved the 3G to 1900 MHz.
I have a Net10 sim which runs on the AT&T network and I have HSPA+ only, no LTE, which is good enough for me

Of course I know what the thread is, but perhaps mentioning you were using the same phone would have been good. Just mentioning using a different MNVO made it sound like you were just using Net10, not necessarily the same phone.
My bad..
