Hi, i have a big problem with my LG G3 bought on january of this year. the version is the D855, italian warranty (as i am italian). from the moment which i put my SIM into the cell phone i noticed that it doesn't connect to 4G network (as just it found a 4G connectivity it started to search another network till it'd have found a 3G/H+ connectivity), delivered twice to the customer service (so i staied two months without mobile), LG wasn't able to solve the issue said that their test on the network was all right, now i found the only one provider that works with my device (i'm talking about H3G, before,when i bought it, i had Vodafone, but i have tried Wind and Tim though), but now i want to change it because it costs an arm and a leg, and i want to solve this problem by myself (as LG do nothing to solve it) and it seems there is no one with my same issue in the world wide, so what it would be a probably solution??? ask for other infos if you need!!!

If LG found nothing wrong with your device, and and only one operator has 4G working on that phone, it means that your phone doesn't support the bands other carriers are offering.
LTE bands for this phone (855) are 700 Mhz,800 Mhz, 900Mhz, 1800 Mhz, 2100Mhz, 2300 Mhz and 2600 Mhz.
Also, worth noticing is that the coverage differs from carrier to carrier.

i don't think that the problem is that, here are the LTE bands of the main italian carriers (included H3G):
-Telecom Italia: 800 MHz, 1800 MHz, 2600 MHz;
-Vodafone Italia: 800 MHz, 1800 MHz, 2600 MHz;
-Wind Telecomunicazioni: 800 MHz, 2600 MHz;
-H3G (3 Italia): 1800 MHz, 2600 MHz.
i have tried each one of these but the only one that works is H3G indeed and besides is the only one that doesn't own the 800 MHz band, so maybe the problem is that my mobile is not able to connect on this band (although it is available as you mentioned in your specs ). so is there a solution? p.s. on my old G2 work all four of them so it is undeniable that my G3 has a problem, i want just know if this problem is resolvable by myself and how!
whatever thank you for the help

hi guys,
check this out..
http://personaldigital.com.au/p171/HTC-Touch-PRO-2-T7373-850-Mhz-NEXTG-%21%21-PRO2/buy.html
It has those frequencies selectable out of the box on any version I believe.
no, you are taking about the GSM bands
i was talking about the UMTS/ WCDMA 850/2100
Most versions WORLDWIDE are 900/2100
850 is the AT&T (USA) and Telstra (Australia) 3G Bands
I am under the impression AT&T and Rogers/Fido also use the 1900mhz for downloads. The 850 bands is only the "upload" band.
Yeah, but paying around 400 dollars more for an 850mhz band you must REALLY want it.
Wait a second
I know att uses the 850 and 1900 bands for 3g but I never heard that the 1900 band is for downloading and the 850 band is for uploading. Is this true? Can anyone confirm this 100%?
I was holding off buying the samsung omnia II because it only had the 1900.
Unless I am mistaken, when do you really need to upload anything on a mobile phone?
I hope someone can confirm this asap because then I can get an omnia now instead of waiting for att to release the tp2.
I have a hard time finding a credible source that explains the use of the two separate Bands but I saw it mentioned more then one time.
Anyone got a source with Provider/Bands/Usage, it would be a great tool.
If the bands really serve separate function it's a problem because upload is essential to downloading because you need to tell the server what you want to received hehe.
So 3G band are the following: T-Mo uses 1700/2100, this phone would be a 850/2100, ATT would be 850/1900, Europe would mostly be 900/2100, etc.
at&t has two separate 3G bands; 850 and 1900 mhz. these two bands are independent of each other and each one does upload/download. (this is unlike tmobile which uses 1700 for download and 2100 for upload i believe). So the best thing is to figure out what area you are in; most areas are mixed with 850 and 1900 and some areas are only one or the other. At&t is making a move towards more 850mhz because it is the better penetrating band. I know in south florida it is mostly 850mhz with a little bit of 1900 in miami. Hence why my old Nokia E51 (has 850 and 2100 mhz 3G, like the Telus TP2) worked perfectly down here on 3G. hope this clarifies it
Thanks for the input.
I gotta see what`s the deal with Rogers/Fido in Montreal!

I have a Touch HD from Telstra, i am using it on ATT in CA, it only has 850 for 3g, and it works for both, up and download. My area has mostly 850 and some 1900, I get 3g almost everywhere. works great.
Not worth it. I'm sure the AT&T version will be out within 2 months.
You will end up paying $500-$600 just to have a half-working one up to 2 months early. Its not even unbranded.
That's wrong. According to that page (and others), the Telstra version is a bit over a thousand dollars, not just 400-500 US. And you're right, seems the AT&T version will be out in October.
I mean $500-$600 more than the AT&T version.
your missing the worth
the point is you'll get the original HTC device included with the front facing camera the original keyboard none of the filler apps (that slow down the phone) and the sleeker look with out posibly loosing the straight talk technology. who knows what att will remove to save on cost.
Its already been shown. It loses the front camera and the keyboard arrangement is different. And it has an AT&T logo. Do you really want to pay $500 more just to not have that little logo? The front camera is useless in the U.S. and the keyboard is just different, not worst. Flash the original ROM or any cooked ROM and all your software issues (and lockouts) are gone. Plus with the AT&T version, you have access to super fast replacements if anything were to happen.
Heck, for that price you could possibly buy both the US and the European version, getting coverage basically everywhere in the world
Well, it's just as the title of this thread says... I have a Tmobile's G2 (A.K.A. HTC Vision), which its 3g default bands are under 1700 / 2100. Here on my country, all the providers have their 3g services on 900 / 2100.... soo... Is it possible to Flash T-mobile G2's Radio, an set it to work on 3g 900/2100 mhz, so I can use the phone on 3G, instead of that annoying and extremely slow EDGE??
Or, is there a Custom ROM that has these settings on it? (I mean, a rom that automatically turns the 3g band to 900 instead of 1700)
Thanx.
No you can't, the radio bands are set in hardware (e.g. the physical antennae in the phone), not just in the radio software.
Why would you need to, the phone would use the 2100 band for it's 3G in your country? I took mine to Russia and it worked fine.
I don't think it's that simple. I only get edge on my T-mobile G2 using the Rogers network.

Rogers doesnt use 1700 or 2100 so that is to be expected. The original posters country has a 2100 3G, I would suspect he just isn't in a coverage area.

I don't think it works like that, I think it needs both bands to work. If it was that simple then surely they wouldn't bother making different phones for different markets (e.g. T-Mobile US vs Europe/Asia)
That may be...I'm only speaking of my experience in Russia, they have 2100 only 3G and mine worked without the second band.
Just to add, T-Mobile US use the 1700 MHz band for the uplink, and 2100 MHz for the downlink. So presumably the phones (i.e. G2, as opposed to the Desire Z) are physically setup like that too.
Oh I thought Rogers uses 2100. Either way, no worky.... sad.
Sent from my HTC Vision using XDA app.
Ah, I think I'm following you, because Russia exclusively uses 2100 for up and down my phone worked, but since his county has a seperate uplink and a downlink band it won't?

Yeah I think that's it. I don't know *that* much about this myself, just picked up on a few discussions about the G2/DZ on here over time.
Have a look at this - http://en.wikipedia.org/wiki/UMTS_frequency_bands
I think the "problem" is that the G2 uses exclusively "Band IV" for 3G (i.e. 1700/2100 split), but somewhere like the OP's Dominican Republic uses Band VIII (900).
What the OP needs is a Desire Z, which operates on Band I (2100) and Band VIII (900).
Russia appears to use Band I (2100) as well. Maybe a G2 can partially work there then ?
Rogers uses something else, Band II (1900) and Band V (850).
As I say, I'm don't know that much about this myself, so if anyone else can help clarify/confirm/deny, then that'd be great.
Much appreciated.
Sent from my HTC Vision using XDA app.
Via Google, I dug up another interesting piece of info.
Although it's not on HTC's official spec list on their site, on T-Mobile's support pages it says that the G2 does Band I as well. Which would explain how it would have worked in Russia. That's not going to help the OP's problem though.
http://support.t-mobile.com/doc/tm24233.xml?&A2L.SERVICE=FeatureSummary
Wow mega confusing, but you helped clear it up, thanks!!
Mine worked very well in Moscow, I was pleasantly suprised, it was kind of a bonus to be able to get on the web, I wasn't expecting much.
I don't understand why the manufactures don't provide phones with penta-band 3G support like the Nokia N8. Maximize profit when producing 2-3 same phones with different frequencies maybe? I mean quad-band GSM has been supported for pretty much all of the current phones, why not 3G bands as well?
Has anyone tried this option?
bring up the dial pad and dial
*#*#info#*#* (aka *#*#4636#*#*)
press "Phone Info"
you'll get the screen with the imei, phone no, network and a button that says "Run Ping Test" at the top
press your "menu" button
when the menu pops up, it'll have 6 options, select radio band, view sim address book, view fixed dialling numbers, view service dialling numbers, get PDP list, and More.
Choose the first one "Select Radio Band" then select the appropriate band.
Not sure if it helps in this situation, but I found it in a thread about gaining 3G in Europe on the N1
hey bro.. I read from one topic in TMo's official G2 forum that the G2 will work on a country with only a UMTS band of 2100 both for up and down (the answer is from TMo employee, an engineer)... hope you'll be enlightened. I bought an unlocked G2 and I researched extensively before purchase. Im from the Philippines which only supports the 2100 band for 3G. I Know and Im 100% positive that the phone will support the 3G band here in my country. cant wait for my G2 (arriving tomorrow)
btw... coverage is vital. if the 3G signal is weak or non-existent in your area, you'll be switched to edge for data on your phone (naturally).. good luck
sorry.. cant post the link. would've loved to have posted it.

That's the Band I thing that I was talking about, that T-Mo shows on their spec sheets (but HTC doesn't seem to list, for some reason).
I think the G2 will do 3G if any one of the two bands are supported by the country. Correct me if Im wrong

There is nowhere in the world that uses 2100 in both directions. Band 1 is 1900 UP, 2100 DOWN.
In all cases, your phone must be able to upload on the frequencies that the towers listen on, and download on the frequencies that the towers transmit on.
I.e., north america vision transmits on 1700 or 1900, receives on 2100.
OK...the Desire Z only supports 900 and 2100 MHz which is European and Asian 3G bands. Is there any way that it can be made to operate on any North American 3G bands (like 850, 1700/2100, or 1900) or the issue is entirely hardware related, in which case nothing can be done. I should note that the phone has already been upgraded to 2.3.3 so the rooting options are rather limited.
Any contribution will be highly appreciated!!!
Its hardware limited to the bands you have. My understanding (correct me if I'm wrong) is that with that device (if it is unlocked) you will be able to use a T-mobile SIM to get 3G in the US. I'm not 100% sure with this though, as I don't think the DZ has 1700mhz which is needed for T-mobile.
You don't have the correct bands for AT&T 3G. There is a Canadian version of the DZ that will work on AT&T in the US on 850/1900, however.
The device is completely unlocked and unbranded but its specifications clearly state that its 3G frequencies are 900 and 2100.T-Mobile's 3G is 1700/2100 (together) and it's different from the European 2100. Unless the North American bands can be activated via a secret menu, or by flashing a different radio (impossible with 2.3.4), the phone, as is, can't connect to American 3G networks...only GSM 850 and 1900.
So, a miraculous secret menu appears to be my only hope, which, of course, is impossible to implement if the hardware doesn't support it!
Thanks for your concern!
Well, with you phone, you can use only half of tmo's 3g service since they reserve one band for uploads and the other band for downloads. So technically you kinda get 3g, but just 1 way.
Sent from my Desire Z via XDA App
I'm afraid that i can't do that either because the TMO's 2100 3G frequency spectrum is not the same as the European one!
I think I'll exchange it with a friend's European Nexus S which is tri-band 3G and, besides 900 and 2100, it supports TMO's 1700/2100 band! It is an excellent phone but I slightly prefer the metal and the weight of the Desire Z despite the fact that I do not particularly care about the physical keyboard!
Thanks anyway guys!

yea. i think mputtr brought up the correct point. The way T-mo uses 3G is 1700 and 2100 separately for down/up, so like you said its different than the Euro 2100 spectrum.
Sorry it didn't work out.
I purchased the newly released UMI X2 Android phone. I am unable to use the TMobile 3G network. I am only able to use 2G/EDGE.
Voice and data quality are very bad, almost the phone is unusable. I spoke with T-Mobile and was informed that my modem does not support 1700 MHz and there are effort to re-farm TMobile network to support 3G on 1900Mhz but not set date yet. When I scan for available network I get three networks were available
T-Mobile 2G
AT&T 3G
AT&T 2G

Did you make any progress with this? I recently purchased UMI X2, for use with T-Mobile UK. But have the same problem of not being able to connect to 3G networks - it works okay on 2G/EDGE.
I know the phone supports 3G on 2100MHz, and there's been some debate whether it supports 850/900MHz as well, but I've not found a definitive answer to that.
There's an operator in the UK (Hutchinson 3G UK Ltd) that only have a license for 2100MHz. So I was expecting the phone to work fine on their network- but no go... phone won't register on network at all - even though it shows in the available networks list.
I'm now searching to see if anyone else has been having problems - as it's beginning to look like faulty phone hardware - rather than trying to use unsupported frequencies...
acid meaand
I am still in the same situation, I am unable to use the 3G network for T-Mobile.
I am looking into getting 4G Wireless Hotspot modem $50 from the same carrier, use my SIM card on the modem, and use my UMI X2 as pure IP phone. There are many issues, but it looks promising.
Please keep me updated with any progress you make.
Regards;
I have the same problem...
I have this same problem with a operator here in Brazil. Every 3G operator in Brazil, using 2.1GHz band, works fine except one: VIVO.
I can see the network when I click on "manual search", but the phone can't connect. My baseband is:
moly.wr8.w1248.md.wg.mp.v7.p1 2013/04/10 00:39
How can change this baseband to another? I tried to update firmware but unfortunately the newest firmware has the same baseband version.
firmware update will not solve the problem
Firmware update will not solve the problem. Until the manufacture identifies the problem and provides a solution, the problem is outstanding.
Beside the hardware has to be compatible and can support more frequencies which no one can confirm for the UMI or any other chines unlocked phones.
But, this is just my humble opinion.
I Found a solution (at least for me)
I think I found a solution for my problem. I flashed this very new (2013/07/17) rom, with a new baseband MOLY.WR8.W1248.MD.WG.MP.V7.F2.P1, 2013/07/10 23:14 that corrects 3G dropouts and disconnects. Now my 3g works find, with H and sometimes H+. Fast and reliable like it should be. The link for this new ROM is:

I have two questions.
1- There are two files in the link you provided UMI-X2-basedon_Official_250613.zip and UPDATE_UMI-X2-THB-ROM-based_on_Official_170713.zip. Which do use?
2- You mentioned the updated corrected 3G dropouts and disconnects, but do you know if the update have these frequencies to get 3G?
3G (850, 900, 1700, 1900, 2100 MHz)
HSPA+ 42
P.S
GSM/EDGE/GPRS (850, 900, 1800, 1900 MHz) original specs

I used the file UPDATE_UMI-X2-THB-ROM-based_on_Official_170713.zip. It was based on the Official ROM from 07/17/2013, but I was unable to find the official stock version. This version has a very new bandbase that, supposedly, fixed the problem with 3G on some operators.
3G on Brazil is on 2100 MHz, sometimes on 850MHz but in my case the problem was on 2.1GHz band. Three WCDMA operators in Brazil, all in the same 2.1GHz frequency, work fine, but VIVO doesn't. Now, with the new rom, it works with no drop outs for over a day now.
no changes or additional frequencies
I successfully applied the update but no changes or additional frequencies
I have serious issues with HSDPA, t-mobile uk works but only on GPRS and it keeps dropping out. GiffGaff seems to work without dropping out. It has worked for a minute on HSDPA today but only once. Other than that t-mobile has been dropping out badly. GPRS works for a bit then it drops out. I have took an MTK modem log with MobileUncle Tools to see what it says but haven't looked at it yet. Trying to work out if it is a hardware issue or Baseband.

Hey everyone,
I'm on bell mobility in canada and bell does have 2600 mhz support. When I use the Lenovo Vibe shot, I only get 3G connection, NO LTE.
Is there a way to change this??? Is there a way to fix this? Hardware wise, it SHOULD be able to connect to 2600 mhz on bell mobility LTE but it doesn't. It goes only as far as 3g.
Please help me!! I'm trying to deal with this for weeks and I can't find any solution.
I'm wondering if you don't have the Chinese version vs the European version... Another member reported that even though the specs were listed as the same, some bands were not present in the Chinese variant.
http://forum.xda-developers.com/showpost.php?p=62737607&postcount=17
FML! It is the chinese version! but i bought it from etotalk.com! It listed 2600 mhz frequency explicitly....
is there anyway to select the LTE band?
