[Q] HTC Vivid on Tmobile 3G/4G? - HTC Vivid, Raider, Velocity

Hi all,
I was wondering whether there would be any way to flash a custom modem or a ROM that would unlock the LTE bands so that the Vivid can access HSPA on Tmobile's network?
From what Ive read, the AT&T GS2 Skyrocket and the AT&T Galaxy Note have been unlocked through this method and Im not sure why the Vivid cant be since it shares much of the same specs between it and the Skyrocket & G-Note
Thanks

No that isn't possible, tmobile and att have different bands. I know that you could use a sim card on the vivid, but you wouldn't get the same speed.

IIRC you can use a T-Mobile phone on ATT and get 2G but can't use ATT on TMO.

The LTE band can be used on Tmobile to get 4G download speeds. As visible here:

OP is asking if this is possible for the Vivid, need a Tmobile radio to flash. Would be great if someone could work on it.

No. The LTE Band will never work on T-Mobile's GSM. What allows the Note and Skyrocket to work is that they have the pentaband hardware GSM modem and flashing a different software modem enables access to those frequencies on GSM.

Uh yeah, it's going to be hard to get the LTE bands on the LTE radio on the phone to pick up UMTS/HSPA signal.
There's a reason why phones are usually advertised like:
GSM/EDGE 850/900/1800/1900MHz
UMTS/HSPA 850/1900/2100MHz
LTE AWS700MHz
They kiiiinda aren't interoperable. Note how you can't connect to UMTS 900MHz or use a Telstra LTE phone and get 1800MHz 2G service if the phone doesn't have that band in its 2G spectrum.
I remember reading about the pentaband radios having UMTS/HSPA 850/900/1700/1900/2100MHz. That's still pretty different than your standard quad-band GSM radio.

It is absolutely possible...given that the specs on GSM Arena and Phonescoop are right...
700 MHz Class 17, 1700/2100 MHz
It has the correct pair for Tmobile.
The only thing is whether or not you can flash the radio with a Tmobile equivalent (Amaze?) radio.
What happened to all the hardware hackers on this forum? It seems as if no one knows ANYthing about the interworkings of a network anymore.
Anyhow, the phone having the bands and knowing what to do with them are 2 different things. For example. Stereo FM 101.9 Mhz vs. HD(Digital)-FM 101.9...they're both on the same band/frequency but are utilized differently...
The signals are still transmitted on the same frequency, however the radio itself doesn't know how to decode/interpret the HD (Digital) signal...unless it is told how to do so.
The only place that this analogy differs is when it comes to actual comparison of FM receivers and Cellular phones. With FM receivers it actually requires a decoder to understand the digital signal being broadcasted...Cellular however just needs to be flashed and voila, you've got HSPA...
So. Yes. It is %100 possible.

NO NO NO NO.
LTE bands do NOT equal GSM. Not going to happen. They are physically different receivers for lack of a better phrase. There is no way to do this without physically changing hardware. Also, you realize T-Mobile's "1700" frequency does not actually mean 1700 on the dot. They use a different subset of actual radio bands than AT&T's 1700 LTE. As in 1721-1727 or some such vs 1781-1793 or something. I don't know the actual frequencies, but you get the drift.

It is absolutely possible. No question about it.

Then do it. For one, there is no compatible modem to flash. Two, it isn't possible.

Hand is hitting my face so hard right now.
RavenII, if it's so possible, then why don't you do it? If you can't, give a large donation to one of our developers and tell them to do it.
I, and many others here are blatantly telling you it's not possible for clear reasons.
The Galaxy Nexus has a PENTABAND UMTS/HSPA "3G" radio. 850/900/1700/1900/2100. That's why it can access TMobile's 3G and faux-G. We here, on the HTC Holiday, have a tri-band 3G radio.
DIRECTLY from your sources at GSM ARENA and PHONESCOOP. I've added HTC.com for good measure:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 1900 / 2100
4G Network LTE 700 MHz Class 17 / 1700 / 2100
GSM 850 / 900 / 1800 / 1900
LTE 700 / 1700
WCDMA 850 / 1900 / 2100
LTE (AWS/700), HSPA+/UMTS Tri-band (850/1900/2100MHz), and tri-band GSM/GPRS/EDGE (850/900/1800/1900MHz)
What? I'm sorry, I couldn't hear you over the fact that "3G network/WCDMA/HSPA+/UMTS" doesn't have 1700MHz. Oh wait, I couldn't hear you over the fact that TMobile's faux-G is not based on LTE, nor is it 4G (big hint: it's 3G HSPA-based service ).
GSM Arena and Phonescoop also do not account for the of LTE bands supported by the Vivid. Each region of the Holiday pretty much only supports the LTE band in that region. Rogers and ATT only supports AWS700, Telstra only supports 1800, etc.

I'm glad I'm not the only one to retain my senses about this. Leave it to a fellow Saab fan to explain it correctly.

Ok...I really didn't want to do this since I HATE spoon feeding people on forums...but here goes. And try to keep up because I'm only going to dumb it down so much.
What you guys are mistaking for "Bands"...really ARE NOT BANDS....there is NO SUCH THING as an LTE band...or HSPA+ band...
There are Network types ...LTE, HSPA+, -Insert other modulation/channeling scheme here-, etc.
There are Frequencies (which are actually specific ranges but for the sake of confusion, they're referred to as the following 700, 800, 850, 900, 1700, 1900, 2100...etc.) By the way...all those frequencies fall under the UHF band...
So far we've established that there are Network types...and different frequencies...are you still with me? Any questions?
Ok, onward.
There exists something called an SDR or Software Defined Rado...it has the ability to receive and transmit on certain frequencies...It's the software that defines how much of that frequency to use per channel (1Mhz, 25khz, etc.), what range of frequencies to use, how to use them, how much power to use while transmitting, among MANY other things (what frequency to send on, which to receive on, etc.)...That's how they came up with "Software defined radio"
If you look at the Product Brief for the MSM8X60/APQ8060 you should notice all of the frequencies that these specific chips support...
I really don't want to lose you guys, still following?
You might notice that the APQ8060 doesn't have a WWAN modem...but what does THAT mean? It means that it needs something like ohhhhh let's say the MDM9200...FINE! Here's one more spoon full
Reader to me: But RavenII...you're being a condescending ****, and we still don't know what the hell your point is...you're spewing all this **** like you're some know it all...
Me to Reader: There there grasshopper. I will get straight to it...
With all of the information I've given you...you should be able to see that when you see something like "LTE (AWS/700), HSPA+/UMTS Tri-band (850/1900/2100MHz), and tri-band GSM/GPRS/EDGE (850/900/1800/1900MHz)"...it means the radio is...
Being told to use LTE Standards (modulation, channeling, frequency steps, etc.) on AWS/700 (which if they're using AWS to signify Band IV...it would in turn mean 1700/2100), HSPA+/UMTS Standards on 850/1900/2100MHz...etc.
Still reading?
When I say that it is %100 possible...I'm saying that with software or "flashing the radio"...you can effectively change/tell what the chip should do (in this case either an MSM or MDM) with the frequencies it's capable of transmitting/receiving on. That's it.
Aus_Azn: I really hope you didn't leave a hand print on your face...
Thank you, good night.
One last thought: I never said that I would do it, I said that it's possible...

Here's the real simple way to explain it: it is theoretically possible to do but no one outside of HTC has the skill or proprietary code to do it.
So for all intents and purposes, impossible. It will not now nor ever happen.
Also, while the chip may support all bands from the factory that initially fabricated the chip, it may be locked at a firmware level (not a software radio, but actual ROM on the physical chip) that a software based radio cannot affect. This is why you can't just flash a T-Mobile software radio on another AT&T s-off device and have it work. The physical chip itself DOES NOT SUPPORT THE FREQUENCY NEEDED due to changed firmware configuration.
Is that condescending enough for you?

Let's see, how can I put this...You're still wrong. It's still possible.
I don't even own a Vivid so I'm no longer going to post to this thread...but I will tell you this...everyone once told me that blackberrys could not have data without having the BIS (Blackberry specific plan)...and guess what. I'M the reason that people are hacking them away. I was the first one to figure it out and prove everyone wrong. While I don't have a phone that I need to convert for T-Mobile, you can bet, that once there's a phone that I want to use on T-Mobile's network...I'll more than likely find a way.
Farewell.

@totally off topic
RavenII I think you're going on the right track here. I'm already convinced by what your saying.
peaceout

What RavenII is saying does have a good base logically because it has been done before for a very similar set of hardware to the raider. The ATT Galaxy S2 Skyrocket and the ATT Note LTE are both phones featuring very similar processor and modem as the Raider. The APQ8060 and MDM9200 (i think).
Samsung released devices with this modem running on all sorts of bands 1700, 850, 1900, 2100 and even LTE on 1700 and 700.
The ATT Versions of the devices do not feature UMTS in AWS range however people have simply flashed the modem from the T-Mobile version of the device which doesn't have LTE and the ATT LTE devices actually started working on UMTS AWS bands. Various modems give various degrees of success but it is possible and has been confirmed many many times over.
Here is the thread for the ATT Skyrocket. You will find people doing the same thing on ATT Galaxy Note LTE.

You guys are funny, now I can't wait to get my Vivid which I just received today running on T-Mobiles "4g". The funny thing about this is when i very first started reading this thread and saw Mr. buknastys' reply, I was thinking "That is absolutely not true". Now I'm not going to go into detail or try and prove any points, as Raven has done a perfectly fine job proving his point and answering the OPs question. Bottom line; the two readers are absolutely wrong and Raven is absolutely right. Also one last thing, I love how suddenly a firmware "lock" is something of an obstacle, yet we have gained S-Off on nearly every HTC bootloader out there. Just sayin..

...I encourage you to try, but do so with a lot of caution...because the fact of the matter is...you can brick your device...

I would just like to say thank you to Raven as I now have a AT&T Vivid and have successfully placed it on the T-mobile 3G network working 100% of the time. I will be putting together a full tutorial on how to do this shortly as it was indeed a challenge. I have been reading these forums for awhile and Raven your post has by far been one of the most beneficial and inspiring ones...thanks for sticking it out on these forums...few do these days. I actually just joined this forum after months of reading because of this post. I figure i too will provide feedback. I am actually a Tech Manager w/ Sprint. I work on these things everyday in other words....hints why I actually have a T-mobile phone lol. Not saying T-mobile is the best but you at least get exactly what you pay for and they are honest about coverage haha. Anyways..back on topic...the HTC Vivid is an interesting phone to root even and get the S-off. It is needed in order to get the sim unlocked. You have to do a combo of the rooting kit "Vivid_All_in_One_kit_v2.2" posted on another section and the "ControlBearRelease_holiday_ICS_WIN" (if your running Win 7). After you do what they call the "wire trick" (basically short the sim reader temporarily to allow temp access to flash) you can get the sim lock off. After that it is simple trial and error with modem flashes from various tmobile devices onto the HTC Vivid to get the 3G up and going. Mine actually kicked on with the AT&T radio flashed at first but I only had coverage in certain areas. Basicly it will depend alot on your local towers. Believe it or not...ALL CELL TOWERS ARE LEASED FROM VARIOUS COMPANIES LIKE SONY ERICSON WHICH MAINTAIN THEM ALL ALMOST!!...therefore it is very dependent on the towers in your area which radios are likely to work if not the stock modem on the device. It depends on what lease and roaming agreements are in place in your region....again...I WORK ON PHONES EVERYDAY FOR SPRINT...know a little about all that stuff...trust me...i have people yelling everyday about not having this or that when most of it is the carrier hasnt signed an agreement with Kyocera or whom ever to support that device or the lease contract has expired and will be resigned in a few days....bottom line is ....if the phone has a radio chipset that supports multibands and frequencies it is almost always possible to do what ever you would like with it. As far as firmware lock....too funny...those do not work on Android devices as the chipsets were intentionally designed to be unviersal to all carriers to cut manufacturing costs...much like in automotives where Mazdas and Fords use the same parts...just a reference. Anywho....It really is possible...it just takes research and a TON of time sometimes but that is the point of hacking....most would have said the Xbox Kinect wouldnt have been able to been hacked or the Wii remote seeing as both those use internal chips that range in the thousands if sold for other purposes. Long story short....happy hacking and Thanks to all of you for a great discussion forum.

Diamond & ATT

I couldn't help myself. This phone seems perfect so i ordered a diamond that will arrive tommorow. Now my question is if anyone thinks the bands for US are present and need to be unlocked or if this will end up on ebay . Thanks!
There's several topics about it there.
You won't get any 3G in the US with it, and you'll only be able to use the 1900 band for voice/GPRS/EDGE.
Actually you are incorrect. 1900 Mhz is supported w/3G w/AT&T in certain areas. Unfortunately my Diamond is not even getting an EDGE connection. From what I am hearing the Diamond is only supporting 2100Mhz frequency w/3G according to HTC. Which to me makes no sense.. I am blogging my experience with it as it is the first production unit in the USA.
You just said i was incorrect and correct in the same paragraph lol
This is where all the confusion starts.. For GSM/GPRS/EDGE it does 900/1800/1900 MHz - only 1900 would work in the US. For UMTS (3G) it only does 900/2100 - neither of these frequencies are used in the US.
The protocols and modulation used are completly different for GSM/GPRS/EDGE vs UMTS. The dispersal of uplink and downlink frequencies is completly different. Just because it can do 1900 for GSM doesnt mean it should do 1900 UMTS.

You should get edge. Edge is an extention of GPRS but requires a different BTS (radio tower) setup. Its possible you don't have a strong enough signal, but it sounds like your confident you should have edge in that area.
The only thing i can suggest it to try in a different area - like the centre of town. Also, confirm your APN is setup corectly, the [G] may just be telling you GPRS is available, but not that you can attach.
I know with my elfin it takes a little stronger signal to initiate the Edge icon the first time (ie. after a hard reset). I can't get an edge signal inside my office but once I walk outside for a minute or two, bam I have it. Then when I go inside I still have it.

Diamond had UMTS(2100)+GSM(900+1800),UMTS(850+1900)+GSM(850+1900),UMTS(800+2100),UMTS(850+2100)+GSM(900+1800),UMTS(850)+GSM(900+1800) and UMTS(1700) depend what rom you had in your Diamond and where you bought your Diamond , At&T should be show 3G in US and T-mobile used 3G (1700 Mhz) in New York area
The platform in the phone can support all those bands, so you might be able to see them (like in the test rom) but the antennas are not there. So you won't actually be able to pick up a signal.

I guess all of us US early adopters must hope the hardware is there and can be enabled with a future flash.
T-mobile in the US uses 1900mhz for GSM/Edge and only has 3g in NYC, so I'm figuring that it's a cool stop-gap device until something is available for T-mobile 3G.
so anyone have the rom that had thoose bands....
confused
so im a little confused.... If I buy a diamond on ebay, it wont work in the US? or 3g just wont work? does the diamond accept a sim card?
On AT&T it will give you only GPRS! On Tmobile (NEW) it shows EDGE!! I dont understand this at all!

Voice and EDGE will work just fine as long as you are in a major area that uses 1900 band. You might have weak or no signal when you are in smaller rural areas since those usually extend into the 850 band.
You will not be able to use 3G since the Diamond only supports 900/2100, neither of which are used by AT&T
It looks like if you have ATT you are hosed for both voice and data, as most of ATT voice and data (Edge) is 850mhz. Most if not all of T-mobile voice-data-Edge is 1900mhz so you will have at least Edge. If you're looking for 3g data you're SOL until the US version of the diamond is released.

I don't think HTC cares about America too much any more because it's iPhone territory. As they haven't used their own branding until recently, I think HTC are looking to gain market control and loyalty, and that's easiest where the iPhone hasn't been a huge success.

Again, HTC seem to like doing exactly what Apple are not doing, so they may go for multiple carriers. As far as I'm aware the Touch Diamond, and its branded versions, are launching on every network in the UK. That's the complete opposite of Apple's 'one network per country' policy, and they consequently seem to have dropped it (for example, in Italy).
AGREED 100%!! I have been saying this on my podcast for quite a while.. It is a huge mistake. I am now saying since I just received my Diamond that I took one for the team.. I will post my review as the days go by...

is the USA 3g band going to be a software or hardware update?

My understanding is that there are people who have the TP2 activated here in the US...
but 3g doesn't work since it uses a different band in EU
so...the million dollar question...
is this hardware or software issue and eventually fixable with a rom upgrade in the future?
thanks for your input

Since the hardware is very much like the Raphael hardware I would guess that the correct hardware needs to be in place for US 3G. I hope I am wrong since I have a euro version TP2 here in the states.
yeah...its looking like hardware...
It is a hardware thing. They are on different bands (Quad band and tri-band).

I dont think it is even bands...my TP2 is quad band I believe and can not get 3G with AT&T.
Bands for my phone Quad Band 850/900/1800/1900
yah plenty of US ppl have them but the euro models only have 3g on 2100mhz (basically wifi???)
usa 3g is on different band...
the quad bands are for phone use (i think...but i'm a noob)
att 3g is 850.1900 tibble is 1700 and telstra is 850/1900
so if i understand it right...to gain 3g on different band besides 2100 (wifi/eu) you are looking at hardware

forgive my crude interpretation
some of it is sticking though...lol
If you purchased a quadband unlocked TP2, you will never be able to get US 3G on it unless you can get the hardware modified (which in all likelihood, you can't).
If you have a TP2 with triband then it will either support AT&T (850/1900/2100) or T-mobile USA (850/1700/2100). A phone model will probably not come out that supports both T-mobile and AT&T 3G frequencies. This would require a quadband phone with (850/1700/1900/2100). A phone with all four of those frequencies has never been made.
EDGE will work on almost all carriers, world-wide, on a quadband phone EDGE will work on most carriers world-wide on a triband phone.
850 is mostly used for EDGE (both up and downlink). 1700/1900 are commonly used for uplink 3G. 2100 is commonly used for downlink 3G.
I hope that this clears things up.
As mentioned above, internal hardware is almost identical as the Raphael.
This thread gathered the most information for 3G Raphael in the US.

So probably hardware and no go although LTxda mentioned bricking his Raphael trying to get 3G working with Elite's team and cmonex, so maybe she as something to add !? =Þ

If you purchased a quadband unlocked TP2, you will never be able to get US 3G on it unless you can get the hardware modified (which in all likelihood, you can't).
If you have a TP2 with triband then it will either support AT&T (850/1900/2100) or T-mobile USA (850/1700/2100). A phone model will probably not come out that supports both T-mobile and AT&T 3G frequencies. This would require a quadband phone with (850/1700/1900/2100). A phone with all four of those frequencies has never been made.
EDGE will work on almost all carriers, world-wide, on a quadband phone EDGE will work on most carriers world-wide on a triband phone.
850 is mostly used for EDGE (both up and downlink). 1700/1900 are commonly used for uplink 3G. 2100 is commonly used for downlink 3G.
I hope that this clears things up.

Incredible s with 850/1900 3g bands?

I wanted to get an inspire 4g but the crappy battery life and almost impossible to remove battery cover (for using an extra battery) turns me off so i was thinking of getting the incredible s but my provider uses 850/1900 3g bands , has a model with those working bands been announced?
well gsmarena suggests that this phone already has the ability to use those 3g bands
http://www.gsmarena.com/htc_incredible_s-3788.php
Rather unhelpfully HTC's own website only lists "AWS" as a band rather than specifying the frequencies used (though i think they may be).
http://www.htc.com/uk/product/incredibles/specification.html
Best option is probably to ask someone who's out there though i think there's been success in using this in the USA.

what the hell is aws? i checked gsm and looks like it could work, it says
3G Network HSDPA 900 / 2100
HSDPA 850 / 1900 - North America
I hope someone in the us can confirm this!
Just got this off my INC s:
the radio freq bands mine is allowing
"8.GSM_DCS_1800"
"9.GSM_EGSM_900"
"24.GSM_850"
"26.GSM_PCS_1900"
"27.WCDMA_I_IMT_2000"
"30.WCDMA_IV_1700"
"34.WCDMA_VIII_900"
The specs for the Incredible S says basically it won't work for the provider that your using. The Bell is rumored to receive the device which means if that happened, that specific model will have the 3G bands you desire. It's supposed to be released on April 4th. It's a rumor though so don't get your hopes up.

As an employee of one of Bell's dealer stores I can certify that it's in our system but there's no release date yet.
Bell uses 3G 850/1900 HSPA bands only for their service.
Yes Bell does release this model for sure on April 4

Replacement phone with TMO bands also?

Ok, I know this is an odd question but I am confident it can be answered here.
I want to buy another android phone, it needs to be something fairly recent that ATT still stocks at least online if not at the stores so I can use an upgrade.
And I want to be able to also use the TMO 3G system/frequencies with it.
I know the unlocked Captivate won't work on the TMO 3G system but does anyone know if any other phones have the proper radios to support both ATT and TMO frequencies when I swap out the sim card?
Just to reply to my own thread, after an hour or so of searching its looking like ATT phones currently available do not have the required 1700hz band that is needed for TMO 3G speeds.
I am hopingIi am wrong here and that someone knows otherwise.
I did find a few references to some TMO phones working on ATT bands but those obviously wont help me if I am trying to use an upgrade discount.
I was only searching current ATT phones so if someone knows of an older version let me know too.
Well I would recommend finding more concrete evidence on what freq Tmo has in your area and try this before buying but for example (acording to phonearena) Tmobile's Galaxy S 2 runs GSM 850, 900, 1800, 1900 same as ATT"s Galaxy S 2 (not skyrocket). TMO's Galaxy S runs UMTS 1700/2100, 2100 mhz. ATT's Galaxy S 2 (not skyrocket) runs umts 850, 1900, 2100 mhz. Meaning its possible to get edge, 3g and HSPA+ on att's Galaxy S 2 (not skyrocket) on Tmo. But That would depend on your area and how Tmo uses the different freq.
Edit: Its just an example but you can check more phones to see if any of them have overlapping frequencies.
So maybe there is hope.
I was under the impression that TMO needed 1700/2100 for 3G in my area as one was an upload and the other a download frequency.
What I did was pull up all the Android ATT phones I was currently eligible for and then typed the name into the xda search bar followed by 'tmobile'. That would usually take me to a thread in which someone was asking if that phone would also work on TMO 3G and it was invariably replied that they would only work on Edge with a TMO sim card.
I didnt check the GS2 or the Skyrocket though. I will do that today. Thanks for the reply. I knew there would be xda members out there that would have a better idea than me of how to find out.
I will do you a favor and check both of my gs2's with my wife's T-Mobile sim tonight.

Cool! Thank you.
A bit more research on xda says that there are some TMO phones ( Defy and Amaze 4G ) that work on the ATT 3G bands. That doesn't really help me much though. LOL.

i wouldnt put much hope into it. you might get lucky in that the skyrocket works on TMo, but its doubtful. i have never seen an AT&T phone work on Tmo's 3g

Skyrocket won't work. It doesn't have UMTS 2100 (Skyrocket runs on 850, 1900). The "Attain" (none lte) might because it has 2100.
http://forum.xda-developers.com/showthread.php?t=1299211
This thread says we are out off luck on this quest.
What I said. It might depending on the area. If where the OP lives Tmo uses the UMTS 2100mhz then he is lucky else he is SOL.
Edit: after finishing reading IF the phone uses 1700 for dl and 2100 for ul then ya tough luck D=

[Q] Local carrier has one phone using LTE, am I able to utilize it with the One?

Hello everyone,
I have a question I am hoping can be answered.
I used to own an HTC Dinc with that device I was able to watch YouTube no problem, however I can't watch any videos at all with this new phone.
I am thinking it's just slow connectivity*this is prolly it* but what's so different with my old phone to this?
My local carrier sells this particular model so I bought it second hand, it's a great device don't get me wrong but this one thing is killing it for me.
Is there a way to bring it back to the carrier and have them set it up to use the data like on my Dinc or am I just stuck with crappy connection?
Now with that all said, my local carrier markets 4G LTE but it has only one device which is an LG AS840, I actually asked if I can implement this to my One. They said they can't, I am wondering why wouldn't it work? Is it because the frequencies don't correspond with each other? Or am I missing something entirely?
All I want to do is be able to watch videos when I am not using WiFi*no internet at home atm, I have WiFi at work though*.
Another thing to add as well is, my girlfriend has an S3 which is AT&T branded, well to say it frankly her phone has much better connection than my One. I am also wondering about SIM unlocking, if I SIM unlock will I be able to use a SIM card from her carrier? Currently the carrier she uses is DoCoMo Pacific which uses AT&T branded devices while mine uses Sprint.
If anyone can enlighten me on this subject or even shoot down all my hopes I would appreciate it!!

Who is your carrier, specifically? If your girlfriend is on DoCoMo Pacific, I’m guessing you live in Guam. The Sprint One can only use LTE on the 1900 MHz G-block (Band 25). Currently, I believe that Sprint is the only carrier in the world that uses that frequency/block, meaning the Sprint One will only be able to use Sprint’s LTE network. Since this is part of the physical design of the radio/antenna, it cannot be changed.
Here is the full list of frequencies that the Sprint One can access:
2G/2.5G - GSM/GPRS/EDGE: 850/900/1800/1900 MHz
3G - UMTS/HSPA: 1900/2100 MHz with HSPA+ up to 14.4 Mbps
3G - CDMA: 800/1900 MHz for Sprint
4G - LTE: Sprint: 1900 MHz

In order to access the UMTS/HSPA bands, you would have to SIM-unlock. You would have to find out if there’s a carrier in Guam that transmits on those 3G frequencies (1900/2100 MHz) if you want to do things like stream video because the 2G/2.5G is very likely not fast enough.

My carrier is IT&E.
So doing a SIM unlock will help me at least switch to a different carrier, I was actually thinking about doing it just to switch. But as I was reading the various SIM unlock threads here, it's still pretty sketchy.
How about that LG AS840 using LTE on my carrier, or should I throw that thought out the window?
I will look around and see what kind of prices the carrier's offer, I dont want to be on contract so maybe prepaid is the way to go*I'm actually off contract but still pay my contracted amount.
This device is exceptional but the data speeds here locally suck.
