Hi there,
I've got a Verizon HTC One Max. I rooted and put CM12 on my device, and it seems that some of the network bands aren't compatible with this device. After doing a bit of research, I noticed that the LTE Bands supported by this device are the ones used on my Canadian cellular carrier; However, when I select those types of networks to be used on the device, I get no signal picked up. I'm currently using "WCDMA only" as my selected network band for the device, as none of the GSM, LTE, or CDMA options work. It seems that it only picks up the 3G and 4G bands, but no LTE or GSM.
Now I don't know if this is because of the type of device I purchased (like I said, I found a way to get service to the phone through WCDMA), but I was hoping that maybe I could utilize the LTE network in the area instead of using the awful 3G and 4G speeds.
I'm on Virgin Mobile's network, which is a partner network of Bell Mobility Canada. Their supported network bands are:
"Although both are different and independent from one another, both the CDMA and HSPA+ networks use the 850 and 1900 MHz frequencies. Bell's LTE network uses Band 4 Advanced Wireless Services (AWS 1700/2100 MHz) in most coverage areas and Band 7 (2600 MHz) in a few areas."
The Verizon HTC One Max is compatible with the following:
Verizon: 850/900/1900/2100 MHz with HSPA+ up to 14.4 Mbps and LTE: 700 MHz
So looking at this, I might be an idiot - it looks like on second observation, maybe they're not compatible. I figured I'd post this just to double check anyway for good measure. Anyway, if you've got anything to provide, that'd be great.
Thanks.

Hello All,
I am on tmobile and had samsung galaxy s before i got SGS2 from at&t (my wife upgraded). i unlocked/rooted the phone after reading through the posts and it worked like a charm!
My concern right now is that I am always on edge data network with tmobile. can anyone help me on this. Tethering is also not much of use when i am on the slowest connection. Please help.
Can't do much about it since AT&T version doesn't support the 3g/4g band for T-mobile.
At&t gs2 doesn't support t-mobile frequency for 3 g.
Sent from my SAMSUNG-SGH-I777 using xda premium
I thought this phone has all the bands to support all networks.

No only AT&T.
My guess is that international version supports all the bands not the carrier branded sgII
^Even international version doesn't support T-Mobile 3g/4g (HSPA+) network.. Not many phones support their network. Or maybe it will.. but not everywhere
AT&T SGSII
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 1900 / 2100
T-Mobile SGSII
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 1700 / 2100
International SGSII
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1900 / 2100
I am following another post that lets says HOW TO: "Enable 850Mhz 3G Network Frequency on your Samsung i9000 Galaxy S''. will update how it goes... fingers crossed..

No luck. i read somewhere that i may need to install another modem?
Is there anyone out there with the same issue as mine?
any experts out there?

The AWS (1700) bands are supported only by a handful of carriers. It doesn't exist at all in Europe and Asia. There's little reason for manufacturers to include it on their global phones as so few people use it. It's the reason the T-Mobile SGS2 has a Qualcomm chip instead of Exynos like the rest of them. After the merger, it won't even exist in the U.S. any longer as AT&T plans on using it (1700) for LTE. If you want versatility and the ability to use unlocked phones, change to AT&T.

In order to get T-mo 3G, a phone must support HSPA on 1700MHz AWS band, not 850MHz. As such, only phones from T-Mo or some Candadian carrier support 1700 band. Rest of the world use 900/2100 for 3G and AT&T uses 850/1900 for 3G/4G.
You are never going to get 3G on T-Mo on any phones from AT&T. Period. Give it up.

thanks. i give up
TMobile uses 1700 up, 2100 down. If the handset doesn't support 1700, you are out of luck.
Correct. Many phones support the 2100 MHz International band.
T-Mobile's network is weird though, and uses both 1700 and 2100 MHz at the same time.
My guess is that UMTS1700 support and not 42 Mbps HSPA+ is why the T-Mobile variant of the GS2 is such an oddball phone.
NO AT&T phone and only a small handful of international phones support T-Mobile's 1700 MHz band.
Similarly, only one or two T-Mobile phones (The Vibrant being one of them) support any of AT&T's 3G bands, but none support all of AT&T's 3G bands to my knowledge.
The interesting thing about this entire thing is that if you go into the modem band selection it lists 5 different wcdma bands including the aws 1700. I enabled those bands and tried using a tmo sim but alas it still only worked on edge. It may have just been there cosmetically rather then actually supporting aws bands. use dialer code *#2263# to access the band selection menu. Maybe there is a way to get it to work.

I agree with you and have tried exactly what you did (along with other bands) but still not working.

Typically, the s/w supports multiple versions of h/w. Just because an option's in the menu doesn't mean the h/w's available to support it. The same thing happened with the T-Mobile G2X. It was supposed to be quad-band, the option was in the ROM, but the radio wasn't there to support all the bands.
Ok guys I have an atrix 4g running on t-mobile. My question is why cant I get 4g/3g on this phone ? T-mobile runs on the 2100 band and the phone does support that band so why no 4g or 3g? common sense would tell me that if t-mo runs 4g on 2100 and the phone is capable of running on 2100 that it would work. have searched for a total of about 4 hours or so over the past couple days and cant find a straight answer only thing i can find is that att doesnt run on 2100 band yet the phone does. thanks in advance to anybody that can answer and taking the time to read.
are you getting H+ or H? (This is "3.5g") The Atrix 4g is not a true 4g phone.
Because the 2100 spectrum that you're using the phone on now is part of the quad-band gsm which is edge/2g. The difference lies in the bands used for 3g/4g, in which case AT&T only uses 850/1900 and tmobile only uses 1700/2100.
There is also a bunch of things that include HSPA, AWS, WCDMA, and so on and so on but I don't know enough about that to comment.
EDIT: Also, the only phones I know that can be used on both AT&T and Tmobile 3g/4g are "penta-band" phones like some European Nokia phones and the unlocked Galaxy Nexus that needs to be imported as well.

Wcdma=utms=3g
Yes, WCDMA and AWS(1700), as far as I know, are both from UMTS and the differences in regards to 3G between AT&T and Tmobile lie in the spectrum use (850&1900 vs 1700&2100). And both AT&T and Tmobile use HSPA(+) based off their respected UMTS frequencies.
I just don't understand the "leap" in GSM technology that breaks the quad-band compatibility, that's all.

Also I've read 850 is att's main spectrum for large areas and 900 for T-Mobile. All higher spectrums are for smaller, rural areas.
If your looking for 3g maybe find a town or, buy a dual band amplifier? That's IF they have 2100 MHz band working where you are located.
Lower bands ie 850/900 are the download streams. 1700/1900/2100 are upload streams. If I'm not mistaken
Also a T-Mobile vibrant supports att, it also has our main band, 850mhz. Again which is the main large areas, like T-Mobile 900mhz. 1700-2100mhz for att/T-Mobile range is only as good as the towns that still has that band currently operating for hspa/3g data. I've seen alot of T-Mobile phones that have 850/1900/2100, and work on att. If they were 1600/1900/2100 did not for me.
You need that lower frequencies to ensure it to work. Then....
Also for regional based frequencies...
http://en.m.wikipedia.org/wiki/Universal_Mobile_Telecommunications_System
That link will let you know what that all really means.
I think you are mixing up gsm and umts.
GSM = 2G/Edge
UMTS (HSPA, HSPA+, HSDPA/HSUPA, WCDMA, AWS) = 3G
Have a look here. You will see they label "3G" as "UMTS" which is HSPA/WCDMA. A little more down you can see they label their data as "HSDPA", which is download, and "HSUPA" which is upload. Further delineating the speeds they label either one as UMTS for down and Edge as up, which to me tells me they use gsm for the upload and only use UMTS for download. Either way, there is not a T-mobile phone available that can be unlocked and used on AT&T's 3G, just 2G and vice versa. As I have previously mentioned, you will need a penta-band phone for that.

And don't get me wrong, I'm not trying to give anyone a hard time but it's misinformation to tell anyone that a T-mobile phone can work on AT&T 3G.
And I'll say it again, I'm not an expert so if anyone can better explain then I'm all ears (eyes).

I am just merely stating that I have a motorola defy on ATT, and it worked great for a long time with great speeds before I got a motorola atrix and infuse.
Im not saying that every tmobile phone will have working talk/text, or data for that matter. I have just posted an idea, or atleast what to look for when you are cruising for phones not labeled for your carrier.
I was getting my motorola defy with the att "grand fathered internet" for 10 dollars a month and it was about 160-420KB/s down, and 80-190KB/s up. but some phones are capable of this, others arent. I have a general idea, and have played with several different carrier cellphones and used them with att and att's 3g data.
Rogers HTC Dream (x2 of them)
Telus Milestone
Tmobile Defy
Rogers Atrix
ATT Atrix (x2 of them)
ATT Infuse
Rogers and Telus actually use the same 3G bands as AT&T so as long as those are unlocked they will work. And I'm not saying an unlocked T-mobile can't work on AT&T, because they can (they both use quad-band gsm) but you can not use an unlocked T-mobile phone an AT&T 3G. That's all I'm saying.
Now, they did make an European version of the Defy that uses the 850 3G band but not the T-mobile "branded" one.
I'm going to stick to my guns on this one because I don't want to give anyone the wrong idea about interchanging AT&T and T-mobile phones and expecting 3G service. I'm fairly certain about this and unless someone can prove otherwise that's how I will think.

Upon further research, I have found this article, where under certain circumstances, you can use an unlocked AT&T iPhone with T-mobile 3G:
http://www.gsmarena.com/tmobile_usa_running_1900mhz_3g_in_some_areas_iphones_invited-news-3537.php
Now, this shows that an AT&T phone can maybe use T-mobile 3G but not the other way around. Again, I'm always up for learning something new but I need references/proof.
Well I do get att 3g on the defy and vibrant. I am currently getting about 300ish KB/s on them and 600+KB/s on my attic, I'm just going with the facts. Those facts are that certain T-Mobile phones will work with Att, provided they have 850mhz band. That allows you in most towns (near me) to get 3g
False.
300KB/s is Edge speed, which is only 2G.
http://en.wikipedia.org/wiki/2G
http://www.phonescoop.com/glossary/term.php?gid=107
That's why you get faster speeds on the Atrix because it actually uses 3G.
Again, both AT&T and T-mobile use quad-band GSM. Which is why you can unlock a T-mobile phone and use it on AT&T, and vice versa, but it is only 2G/Edge and NOT 3G.
http://www.phonescoop.com/glossary/term.php?gid=139
http://www.phonescoop.com/glossary/term.php?gid=3
Furthermore, here are the wiki pages for AT&T and T-mobile which both inlcude frequency charts outlining the technology (2G or 3G) each one uses:
http://en.wikipedia.org/wiki/AT&T_Wireless
http://en.wikipedia.org/wiki/T-Mobile_USA
Here are the charts:
AT&T:
Frequency Protocol Class
Frequencies used on the AT&T Network
850 MHz GSM/GPRS/EDGE 2G
1900 MHz GSM/GPRS/EDGE 2G
850 MHz UMTS/HSPA 3G
1900 MHz UMTS/HSPA 3G
700 MHz LTE 4G
T-mobile:
Frequency Band Protocol
850 MHz GSM/GPRS/EDGE 2G
1900 MHz GSM/GPRS/EDGE 2G
1700 MHz UMTS (W-CDMA)/HSPA/HSPA+ 4G (formerly 3G[34])
1900 MHz UMTS (W-CDMA)/HSPA/HSPA+ 4G
I check for facts and references, I'm only saying what I find in research.
Again, when unlocked, a T-mobile phone can use AT&T 2G/Edge, not 3G

hello all,
I was wondering whether it is possible to unlock the LTE radio on the Eu retail version. I think the chipset is the same and hence it does have the capability.
Thanks in advance,
Santanu Dey
Are you saying that your razr never gets 4G / HSDPA signal?
Don't you ever get the little 'H' on your connection indicator?

Not even LTE is 4G. It is called such for pure marketing speculation since LTE is still part of UMTS... it is its 8th revision, actually.
Cheesy, you should first ask your provider if they reach ~325Mbps. Vodafone, the european carrier with the best network, sells 48Mbps (HSPA++) as LTE, which isn't really.
LTE isn't yet fully ratified, actually.
Anyway, it works
For general information:
LTE is Long Term Evolution.
HSPA or High speed packet access and its derivatives are not LTE...
The modulation scheme is different as well as the coding and spectrum and Bandwidth. LTE works in 2 variations TDD and FDD, whereas HSPA/UMTS is purely FDD. Secondly, LTE works in 1.4Mhz, 5 MHz, 10Mhz , 20Mhz Bandwidth whereas HSPA/UMTS is only 5 Mhz.
Basically HSPA is a evolution of data access on UMTS network, as EDGE was in GSM network.
So , returning back to the same question..... Can we unlock LTE radio on the Razr? My operator Telia is already having commercial LTE network (300/100 Mbps DL)..
Beg my pardon I was not aware ( haven't done quite as much research as you guys it would seem ;D )
Can I just ask briefly, is LTE a cdma standard as opposed to gsm or is it something viable on both platforms?
LTE is basically a convergent network between the CDMA and the GSM domains. The radio standard has been designed in such a way that it shares the backward compatibility towards CDMA and GSM domains..."BUT".. LTE is much more bent toward the GSM/WCDMA domain than CDMA/EVDO domains,since it shares the same spectral characteristics of the UMTS networks.
WIMAX on the other hand is more bent towards CDMA/EVDO domains...
I know the Jetstream was designed to be run on AT&T and Rogers, but I am curious if it is possible to flash a radio to enable usage of T-Mobile's HSPA network, much like the Samsung Galaxy Note has been enabled to, as seen here.
Can any of the amazing Devs out there shed some light on this?

jdavis08, Simple answer is yes. It is a standard 2G / 3G / LTE (AT&T / AWS band) phone. So you can use it on ANY 2G / 3G / LTE network with a SIM. But you may need to break the SIM Lock on any handset.
Just wanted to clarify. The Jetstream is 2G/3G/LTE /capable, 2G (GSM): 850/900/1800/1900MHz, 3G (UMTS/HSPA): 850/1900/2100, and LTE: 700mhz & AWS-1700/2100.
Currently, T-Mobile only uses the AWS for their HSPA+ network, not LTE (from what I understand, AWS will be transitioned for LTE and 1900mhz refarmed for 3G/4G early 2013) - and if I'm not mistaken, the HSPA+ is only supported by the "3G" band of this device, not the "LTE"
So - to make a long story short. I am a T-Mobile subscriber with various "4G" phones from T-Mobile. Their 4G only works if the phone has a radio with AWS for HSPA as T-Mobile (unlike AT&T) does not use the 1900mhz for their HSPA (yet). I own this tablet.. It has been SIM unlocked and it simply does not get anything above EDGE... and I live near and visit major cities in Washington State, Seattle/Bellevue/Tacoma, which definitely have TMo's 4G coverage.
I know I should just cool my jets until TMo rolls out the network upgrades, as I have no interest in joining AT&T. I was just curious if there was some way to "trick" the phone to use the AWS frequencies for HSPA, like the Galaxy Note has been made to do as the radio specs are identical.
I know that the Note was enabled to do this by flashing another radio. Support is minimal for the Jetstream these days... so I was just reaching out.
Thanks guys
I have looked for days now across multiple forums to get some insight on this issue:
I want to use my Thunderbolt in Thailand. Haven't found any threads that speak of success, only conjecture that it won't work.
Homework I've done (unless i understand it incorrectly):
- Verizon 3G operates on the 850 / 1900 mhz cdma band. Radio Frequency Summary
" The following is a list of known frequencies which Verizon employs in the United States:
Frequencies used on the Verizon Network
Frequency Protocol Class
850 MHz 1xRTT/EV-DO/eHRPD 3G
1900 MHz 1xRTT/EV-DO/eHRPD 3G
700 MHz LTE 4G
1700/2100 MHz(AWS) LTE 4G"
- Truemove, a popular mobile company in Thailand has early links to Verizon and their 3G service operates on the 850mhz wcdma band
"What should I do if I want to use TrueMove 3G service but I don’t have a 3G 850 MHz mobile phone?
Basically, it’s not that all mobile phones work on any band. Each 3G compatible mobile phone supports different bands. For example, if you have a 3G 2.1 GHz or 900 MHz or 2G mobile phone, you will not be able to use TrueMove 3G service because TrueMove offers 3G service on 850 MHz band.
If you want to enjoy TrueMove 3G service, it is recommended that you buy a 3G WCDMA 850 MHz mobile phone or visit any True Shops and ask for a 3G compatible mobile phone. True Shops also sell different smartphones that support different mobile platforms e.g. iPhone 3G/3GS, BlackBerry Bold 900/Bold 9700 and Motorola Milestone."
- I spoke with verizon after reading other forums about 'unlocking' thunderbolts and was told that the thunderbolt comes unlocked, so unlocking wouldn't be necessary anyway.
- Lastly, it seems that many people have successfully put a 3G SIM into a 4G SIM slot on there phone and received 3G service.
....So what am I missing? What would prevent me from being able to use my Thunderbolt in Thailand for simple 3G service if the carrier (Truemove) works on cdma based bands? What extra might I have to do to get it to work?
PS: Sorry I can't insert the links directly in the post. Not allowed since this is my first post.
Thanks for any help
