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.

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.

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.

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.
Hi,
Does anyone have any info on how to tell what 3G frequency band Im using on the Galaxy Nexus?
Prior to ICS, you could use *#*#0000#*#* to see what 3G band you were on, but this doesnt work anymore.
Also using *#*#4636#*#* doesnt give any info.
Thanks

Stock Android has never had a feature to show which band you're using. Let us know if you find anything but I am pretty sure it is not available.
I am curious about this too. I always simply Googled the provider to learn the band I was using.

There's no way to see the band on stock android.
One of the things I want to find out as well. I am surprised there is no way to find this out on a phone like the Galaxy Nexus..

AFAIK stock android never had any diag menu .
For those looking for my question - skip to the end - I have a bit of background waffle in the middle.
I was also looking for something like this (the iPhone has this feature in its "field test app" *3001#12345# or something like that).
I suspect Google hadn't thought about putting something like this in, because it's only really useful in countries like Australia, where all three major carriers run out multiple bands for 3G/UMTS:
Telstra: 850MHz (Band V), 2100MHz (Band I)
Optus: 900MHz (Band VIII), 2100MHz (Band I)
Vodafone: 850MHz (Band V), 900MHz (Band VIII) and 2100MHz (Band I)
Each carrier operates those frequencies in different regions, with Band I typically in cities (with Telstra starting to install their own network in Metro areas for load balancing for their nationwide 850MHz network), Band VIII typically in regional/rural areas (although Optus is bringing it in parts of Metro Australia), and Band V nationwide (with Voda prioritising Metro regions at the moment).
Seeing as all carriers are currently installing new equipment in the cities (Telstra on 2100MHz, Optus on 900MHz, Voda primarily on 850MHz, but also 2100MHz), it would be handy to see which band my phone is using at the moment to identify when network upgrades have been completed for our area.
Finally, getting to my question - I notice most of the replies say that "stock Android" doesn't have this feature. Does this imply that custom ROMs have this feature, and if so, could someone point me to a custom ROM that has this capability? Thanks
I don't know of any customizations for phones that did not ship with this ability in the firmware.
Some non-stock phones with vendor firmware, notably LG and (NON-Nexus) Samsung, have a proper band select menu. These additions to the OS are closed-source to my knowledge and not available to adapt to other devices.
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

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 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.

Hola folks!
After finding enough screenshots/video reviews, I am beginning to think that from a hardware perspective the S and L variants are identical (including supported bands), whereas the K is only slightly different from S/L.
Any images of the back cover off on the K models (Olleh) will show "F400 0425 K" indicating the hardware is the "K" variant. (If you watch the review video http://www.androidcentral.com/lg-g3-review, you will notice this info up at the top on the backside, right above the camera.) UPDATE: Here is another link with an image http://arstechnica.com/gadgets/2014/06/lg-g3-review-a-great-phone-with-way-too-many-pixels/#image-4
On the S/L (SK Telecom, LG U+) models, they say "F400 0423 S/L" on the SK Telecom model ("S" variant), and "F400 0425 S/L" on the LG U+ model ("L" variant). You can find images of the "S" model with engadget's review (http://www.engadget.com/gallery/lg-g3-review/2676959/#!slide=2676963), and images of the "L" model with ubreakifix's F400L teardown (http://www.ubreakifix.com/blog/wp-content/uploads/2014/05/ubif-g3-21.jpg).
(Thanks and kudos to the review sites and teardown site for the images.)
As an owner of the F400S, I can tell you that all 3 variants will run on AT&T LTE (as a lot of our LTE is on Band 17 - 700 MHz spectrum). I was able to load my F400S with the TOT and DLL files of all 3 variants (currently waiting on getting it back to the "S" variant once the DLL is posted), and all 3 variants will connect to AT&T with no issues (for those of you that plan on importing like I did).
So for those of you who managed to brick your new G3, as long as you can ADB into it, you can edit your build.prop file with the corresponding korean variant model info, and load any stock image. As @wolfgart has posted a great thread with the TOTs and DLLs, I recommend swinging through there for more info. If you have a K variant, load the K TOT and DLL, and you are fine.
For those of us with S/L variants--with the above info and enough tinkering in the hidden menus of all 3 variants, I can tell you that from a hardware perspective these two models are nearly identical. From a modem/supported frequencies perspective, the S and L variants support the exact same frequencies--meaning, if you bricked your S or L version, you can restore it with an S or L TOT and DLL (after editing build.prop if needed) and you will still get all of your original hardware supported bands/frequencies. This is critical for those of you using LTE Band 5 to connect to your data... (should not be the case for any US AT&T users...).
UPDATE: in the 'Android Development' section, wolfgart's thread with the TOTs and DLLs have been updated to now include the files for all 3 models. So unless you know what you are doing with a build.prop edit, probably best to stick with what came with the phones for those who are new to this stuff.
The main difference between the S/L and K phones in frequency/band support is that LTE Band 8 is supported on the K model only, whereas you will get LTE Band 5 support on the S/L models. All other bands and frequencies (WCDMA/GSM) are the same across all 3 models. All 3 also support LTE Band 17, and will connect to AT&T in the US.
Took me a while to figure this out, but I had a long weekend
Cool! nice to know, thanks for the well explained post

Unfortunately, I don't connect to LTE with band 7 so I can't say much on that. However, just based on the hidden menus in both (I am using the L version on my S variant phone at the moment), they both have the same listings of 1,3,5,7 for supported bands.
LTE 700, 850, 1800, 2100, 2600 (Band 17, Band 5, Band 3, Band 1, and Band 7 respectively)
UMTS 850, 1900, 2100
GSM 800, 900, 1800, 1900
The above are the fully supported bands on the S and L variants.
The below are the fully supported bands on the K variant.
LTE 700, 900, 1800, 2100, 2600 (Band 17, Band 8, Band 3, Band 1, and Band 7 respectively)
UMTS 850, 1900, 2100
GSM 800, 900, 1800, 1900
I don't have the K variant on my device now, but I recall the only band difference is that it supports LTE band 8 (900 MHz) instead of LTE band 5 (850 MHz), but other supported bands are the same. LTE Band 5 is one of the primary bands for both SK Telecom and LG U+ (which partially explains why the two phones have nearly identical hardware, including modem support).
Hope this answers your question. As support for those frequencies are built in (and it makes sense on LG as a mass manufacturer--They can use the same modem and just rebrand it like they did in Korea for the S and L variants).
Why is the S one more expensive than the L?

That, my friend, is a question you will have to ask LG and SK Telecom. We sorta see that in the US every so often with "special editions" that aren't really that special and they will add an extra 100ish.
Off-contract, LG U+ is the most affordable right now, with SK Telecom right around $700 USD. With markup and shipping, etc. eBayers are selling it for $750-800.
Also, you have to remember the G3 is a hot commodity even in Korea right now. Had some friends who thought it was funny I got a phone overseas before they even bothered joining the bandwagon.
So though I can't say for sure why exactly it's more expensive, I can definitely say it has to do with the fact that the phone is still only 3 weeks old
And none of those 3 will work on T-Mobile LTE which needs 1700 and 2100Mhz most of time.
There are some spots with 900Mhz support though.
But as much as I want G3, I'll wait for the T-Mo version.
Yeah...I'm a proud owner of a Htc One M7...I have been thinking a lot and decided that it's time to change. I'm comparing the M8, the Z2, the G3 for a long time and finally think that this last one will be the one...unfortunately it's still very soon to easily find information regarding this phone online...

It looks like you are planning on doing the same upgrade I did. I still have my M7 as my backup , but definitely gotta say I am loving my G3.
That's amazing man...I've been a HTC fan since the Sensation...but currently I feel that they are been left behind...
I'm really sorry, but other brands are offering a lot more for the same price.
The HTC will always win in design and the quality of the phone's body, screen and, of course, sound!...but they are losing in the rest...UI, camera, battery life definitely...it's just sad
Nice to know that you're enjoying your G3...I hope I'll be as happy as you are in a few weeks...and judging by how much I've researched about it...I'm sure I'll love it!!!

From my research, none of the korean models (F400 S/K/L) support FM radio. Instead of an FM radio tuner, they are offered with Korea's DMB tuner, for korean DMB support.
I have only seen DMB function while in Korea and Japan. Anywhere else in the world, you will have to check with local providers, as some countries will charge for DMB as a service (just like satellite television).
Hope this helps

The only frequencies it can support is anything broadcasted as DMB. Certain countries offer DMB subscription services, but you will have to research if it is offered where you live.
In the US, DMB is unavailable so I just have a nice long antenna that people crack up at in the year 2014, but completely unusable where I am. I just tell them its for better service as a side joke lol

Any of them will do. I would say go for the one that gives you the best price. At this point, enough AT&T users have gotten their hands on all 3 variants. Most can get LTE through band 17 (700 MHz) which is available on all 3 phones.
Will the D855 variant (with LTE 700MHz) be able to use on AT&T (band class 17) or Verizon (band class 13)?
Or to be more specific, will the D855 cover all 700MHz US band class (12, 13, 14, and 17)?
Thanks!

You would have to check which specific band class of 700 MHz the D855 would be capable of connecting to. As I do not have the D855, and specs are varied on the internet right now, I cannot say for sure.
The FCC had ruled four separate band classes to operate on the 700 MHz spectrum in America--Band 17 700 MHz capable modems cannot connect to any of the other 700 MHz band classes and vice versa. (It was claimed that they did not want to have any network interference issues. Carriers purchased the rights to access certain chunks of the 700 MHz spectrum, and they are isolated to those carriers only.)
I am seeing 700MHz (B28) support on D855 models, but I believe that might be related to certain LTE-A rollouts in Europe (meaning it may not be able to connect to current 700 MHz bands in the US (as the US does not have LTE-A networks at the moment) and new band classes are issued for LTE-A (i.e. Band 28).

In the US, DMB is unavailable so I just have a nice long antenna that people crack up at in the year 2014, but completely unusable where I am. I just tell them its for better service as a side joke lol

Does the antenna stand out much? Or is it hidden? Thanks
Hi - I got a killer deal on an international (Asian model) HTC One M8x on eBay so I jumped on it... After receiving it, I noticed LTE is not working with T Mobile. The phone supports LTE 700 / 900 / 1800 / 2100 / 2600... Before purchasing, I didn't notice AWS/Band 4 wasn't listed. Oh well, still a great device.
I did some research and saw that T-Mo just bought Verizon's 700mhz; but 'Block A' only..? my phone supports 700mhz, but I'm not sure which block it will work with.
I live in a pretty populated area in Southern California, so I would assume that this area will be covered when T-Mo rolls out 700mhz on their network around early 2015.
Will my phone work on Block A? What is the difference between blocks? I just recently learned about the different frequencies, and now I'm hearing 'block A, B, C,' etc.. I'm officially confused.
Anyone with extended knowledge of LTE - your responses are greatly appreciated.
thanks!!!
According to the following Wiki, the 700 MHz bands used in North America are also called Bands 12, 13, and 17. These seem to correspond with the blocks you mentioned (A, B, C) with "700 a" (presumably Block A) corresponding to Band 12.
http://en.wikipedia.org/wiki/List_of_LTE_networks
Of the countries and carriers in Europe, Middle East, and Asia (the "international" M8 is actually called the EMEA version) only Taiwan seems to use 700 MHz, and its Band 28. So presumably, this is the band that is supported by your version.
Not sure, but you might be out of luck (your phone supports Band 28, but T-Mobile bought Band 12?).
It is confusing, I agree. My main takeaway is that there sure a lot of different bands that make up 700 MHz!

Thanks for the info and the link!! After reading the wiki page I did some more Googling.. It seems as though the 700mhz is available through bands 12, 13, 14, 44, 17 and 28. It's crazy that my phone only supports one of them. Too bad I won't have LTE....HSPA+ is horribly slow where I live. (unless it's about 3am, then I get a few MB up and down)
I noticed you have AT&T...are you aware if this phone will pick up LTE on an AT&T gophone? I will consider their $60/month prepaid if it will.
Or maybe another GSM carrier that my phone is compatible with? I would really hate to leave T-Mo but I miss LTE.
thanks again for your help!

T-mobile's AWS platform is mostly going to be a 1900 and 1700 setup if i remember correctly. they have purchased the 700mhz spectrum from verizon but no one is really using it yet. Only Verizon has even started to populate that spectrum with their new X-LTE which no one can really take advantage of. and really the HSDPA isnt that bad. i mean i have a tmobile M8 and i get LTE like 70% of the time but the rest of the time i'm on HSPAP and its fine i get like anywhere between 5-10mbps...

you can look further down the page it shows you every band that they use or own.

Its not really that crazy. When they say "700 Mhz" I think what they really mean is that the actually frequencies used are somewhere around 700-799 MHz. And this can be divided up to many different distinct "bands". If you refer to the Wiki page I linked, you will see in the notes under the North America section, for example:
700 Block B
(↓) 734 – 740 MHz / (↑) 704 – 710 MHz
So the MHz number can be misleading; and its really the Band (12, 13, etc.) that you need to pay attention to. Or both the Band/block and MHz in conjunction really, as its often the MHz that is listed.

Don't think it work on AT&T's LTE network. AT&T uses Bands 4 and 17 for LTE. None of these are supported on the EMEA version based on what we've discussed.
Buying phones from 3rd party sources can be very tricky. US carriers in particular use very particular and often proprietary bands. This was true with 3G, and seems to be even more so with LTE. The bands used by even foreign markets has become increasingly less standardized with LTE (there was a good amount of standardization in foreign regions with 2G and 3G). One has to be very careful and resource thoroughly before buying a phone from any source aside from your carrier.
