are at&t and rogers use same band freq? for 3g and 4g ...lte(this probably not the same)
so...let's say I have a rogers HOX flashed ATT RUU (i know, i have a s-off device)
is it ok to run rogers with att radio, or it's prefer to flash the rogers radio?
...
answer please thanks.
Rogers and AT&T use the same 3G (850 and 1900 MHz) and Googling around, they seem to use the same LTE frequency as well (1700 and 2100 MHz). Also seems that the company was a part of (or associated with) AT&T in the past.
Its often said that the two versions are virtually identical. Hard to say what will happen if you flash an AT&T radio. AT&T, Bell, and Rogers at times seem interchangeable.

thanks man, the 1.82 ruu works perfectly on rogers hox. the radio seems to work for 3g and 4g, not sure or lte since I don't have a lte sim (yet). probably I'm not gonna flash the rogers radio since everything I have it working, When I get my lte sim and data plan arranged with rogers. I will see if the lte is working with att radio if not then i will flash the rogers radio see if it's gonna work.
Any update I will update here.
The question of what radio version is optimal is always a bit of a trial-and-error proposition. A carrier-specific version, in theory, may have some network-specific tweaks. But on the other hand, newer radios can also have some overall improvements.
Add to the fact that (from my completely non-technical standpoint) the Rogers and Canada Bell networks seem to have so much in common with AT&T (possibly due to their past and/or continued association with each other?) its completely possible that there is very little differences in the radios, anyway.
If your reception is good, I'd leave well enough alone.

Hello,
I am a noob at this so please bear with me.
I have a Telus TP2 and I have unlocked it using the software provided by Olipro.
My objective is to switch my network over to Telus' new UMTS network, using one of their sim cards. Right now it is functioning on Telus' CDMA network.
My question is: Do I need to flash a new Radio to accomplish this? My phone still has the 2.05.00 WV radio on it now. I just need to know if I need to go get a WU radio in order to use Telus' new network.
Thanks in advance.

The Telus TP2 supports UMTS 2100.
Telus uses UMTS 850/1900 for its 3G network.
In order to get the TP2 running on the UMTS network you'll want to grab a ATT GSM variant from the states and unlock that.
IIRC, Telus is jumping straight to WCDMA/UMTS so it won't be supporting the standard GSM bands. If that's the case, then your Telus TP2 variant won't have anything to lock onto when it is in "GSM Mode."
Ah dang, I guess I didn't really need to unlock the sim on my phone then because it won't work on Telus' UMTS network...
Oh well, if I decide to go back to Rogers I believe that the Telus TP2 will operate on their GSM network.
Follow up question:
Do I need to get an unlocked Radio to use the Telus TP2 on Rogers' GSM network or will the 2.05.00WV one that I have on now work?
yes, you'll need a WU unlocked radio in order to access GSM radios in the states, and canada as well, i believe.

It depends on the specific radio firmware in the device.
If it is like the Sprint TP2, then yes, you would need a separate radio. Sprint does not SIM lock its TP2, however it ships them with crippled radio software which has the 850/1900 GSM bands disabled so that it won't work with US GSM carriers (it simply doesn't see the network).
If it is like the Verizon TP2, then no, you would not need a separate radio, though you would need a SIM unlock. Verizon doesn't cripple the radio software in its TP2. It simply uses a traditional SIM lock.
I've heard that the Telus TP2 is like the Sprint model, but I've not seen one to verify.
If you're not sure, then you can always flash the unlocked radio (assuming you're using the unlock software from Oli) and it'll work.
Hey thanks for the information gamescan. I scoured the Telus Mobility website and tried to find information about their new netowork but they just call it HSPA+. No where does it mention that it is UMTS or GSM. Oh well, now I know a little bit more about cell phone tech.
I don't even know if theres any real benefit to being on Telus' UMTS network compared to their CDMA. Im sure there has to be something....

Quick 3G primer:
W-CDMA and UMTS are the name of the tech. It's also referred to as FOMA in Japan. Phones generally standardize on the UMTS name, so when you're poking around in your phone and see UMTS followed by a number, that indicates the frequency band that the phone will run on in 3G.
HSDPA, HSUPA and HSPA+ are all further revisions to UMTS. They allow for greater speeds on existing infrastructure so long as both the handset and tower support it.
A rough CDMA equivalent would be EVDO and EVDO Rev A. Older UMTS handsets will still work on a HSPA+ network, they just won't run on HSPA+ speeds the same as a EVDO handset will work on a Rev A network, just not at Rev A speeds.
UMTS is often referred to as "GSM" though that is a misnomer. GSM and UMTS are two separate (but concurrent) technologies. While they often exist together on networks that have been GSM and upgraded, they do not have to exist together. You can have a situation where a UMTS network exists but an underlying GSM "2G" network does not.
The most well known example of this is in Japan where GSM never rolled out, but in your case, where Telus is adding UMTS to an existing CDMA2000 network, is similar.
From a user perspective, there is no real reason for you to want to run UMTS over EVDO on Telus. Telus should have greater EVDO coverage so that's what you'll be wanting.
If you really want to run on the Telus UMTS network, look for an ATT branded Touch Pro 2 and get that. Of course that will not run on the Telus EVDO network.
Thank you again sir! I appreciate the replies.
Just curious about one thing, if Telus' new UMTS network isn't really any better than their CDMA right now, then why do they promote it as such a big deal?
I think I read that in order to evolve into the next big cellphone phase (forget the name) that this UTMS network was necessary but why would anyone care what network they are on as of today?
Also, do you know why CDMA is not the "way of the future" so to speak? I know Telus spent millions upgrading and putting in new towers all over...maybe I should go google this stuff lol.
The future is LTE (which is neither CDMA or GSM).
As for why Telus made a hop to UMTS before going to LTE, I couldn't tell you.
All I can envision is that Telus is looking to be more compatible globally with Europe and Japanese business travellers. It may also be a strategic decision to open up compatibility with more possible phone manufacturers.
Putting 1XRTT CDMA + EVDO + UMTS into a phone is an engineering pain. Adding in multiple frequency support (and properly tuning the antenna) is also a pain. HTC aside, many manufacturers are supporting GSM/UMTS because that's what carriers have. The biggest CDMA markets are the US, Canda and South Korea. While it is a lot of people, it also requires another phone variant.
By overlaying a UMTS network, Telus can suddenly work with any handset that supports UMTS 850/1900. That's what's used by ATT in the US. UMTS 850 is also popular in Australia while Europe and Japan use UMTS 2100. T-Mobile US uses UMTS 1700. Many UMTS phones offer tri-band UMTS 850/1900/2100 support. With one of those phones you can run on just about any current UMTS network in the world (excepting T-Mobile US).
Again, this is just conjecture on my part, but they are possible reasons.
I know this sounds like an utter newb question but Bell and all the resources I've checked are very ambiguous as to which bands it supports. I haven't been with them for a while and the resources online about Bell's network are ancient and unreliable. Just can't get a straight answer.
If so, I'm highly interested in getting a Sensation. Anyone wanna trade for an AT&T Atrix?
Unfortunately, it wont. Just like AT&T/Rogers, Bell uses 850/1900 frequencies for 3g, and this phone uses 1700/AWS. And for 2g, correct me if I'm wrong, but Bell uses CDMA technology for 2g, while AT&T, Rogers, And T-mobile use GSM for 2g, and this phone is a GSM phone.
This phone would work on Rogers, but from what I understand, it won't work on Telus or Bell.

Thank you. I thought I read something about Bell having rights to the 1700/AWS band but that it may only be used for their 2G network. So little accurate information about our ****ty Canadian providers.
I have two Atrix's because of an issue I had with the first one, but it's fixed now. AT&T and Bell Atrix.... maybe I'll switch back to Rogers and just foot the ETF. I don't know...
Hey guys,
I am a little lost on this. I was looking on the Infuse and thought about getting it and unlocking it to use with tmobile and was wondering if i would get 4g speeds on it. Here is the bands i pulled off on AT&T's website for the phone:
GSM/EDGE:GSM/EDGE 850/900/1800/1900 3G - UMTS/HSDPAHSPA 850/1900/2100 4G*HSPA+ with enhanced backhaul
According to this, it should work. Am i mistaken?
Thanks

Um, why would you think it would work? Do you see UMTS1700 in there? I don't.
I thought it used 2100? I don't know much about the bands. Just started reading on who supported what.
tmobile uses mainly the 1700 band for 3g/4g. they also own the 700 band but i dont believe they use it. att is mostly on the 850 and 1900 bands. european and asian bands are typically 900 and 2100 so they dont really use those bands to keep unlocked phones off the network. the infuse does not work for 3g and 4g on tmobiles network, sorry.
ahh ok. that makes sense now. I've mainly stuck with tmobile phones, except tried an iphone a couple of times. but att has some cooler phones that i thougth i might want to try, but guess that won't happen now . I use the net on my phone alot, so it would be an issue.
Actually AT&T's weird bands have nothing to do with keeping unlocked phones off their network, just the fact that 2100 MHz wasn't available in the US for any carrier.
UMTS2100 is for international roaming, as it's the standard UMTS band in almost every other country.
T-Mobile uses 1700 and 2100, and you NEED both for 3G/4G to work.
i though the att bands were the same as rogers, bell, and telus use in canada? and the same as used in some other countries in the americas and in places like new zealand. i wouldnt exactly say att has the weird bands in this case.
maybe in a year or two att will merge networks with t-mo and you will have a huge selection of compatable phones.
its the same as rogers in canada, and telstra in australia. i belive bell and telus are cdma.

the bell vibrant is an i9000 and the telus fascinate is a t-mo vibrant, the modems all work on the captivate. trust me they are all gsm networks and fully compatable with att phones.
Forgive me if this is a trivial question, but since European carriers such as Vodafone and O2 Germany also have the dual-core version of the HOX, is it possible to flash a european radio and use the European LTE frequencies? Or are the frequency bands hard-coded into the chipset?
It was my assumption that the US and European LTE variants used the same hardware components, but were just set up to use different LTE bands.
Frequency support is set in hardware.

Thinking more about this, I'm still not convinced it's impossible to flash a european radio on the HOX to swap LTE bands. Unless the physical antenna is different, I'd think that it's a possibility.
With my other phone, the Samsung Skyrocket, we can flash T-Mobile radios to gain support for the 1700 AWS band. The chipset supports it, and it just took a radio flash to activate it. AFAIK, you can't use 1700 and LTE though - that or a radio with support for both doesn't exist.
I guess it depends on what chipset the German One XL uses..but I'll wait to see if someone has luck before I risk my own One X.
The hardware is different, as I already said.
The Skyrocket (and a few other AT&T phones, like the Galaxy Note) included the AWS band in hardware (likely due to the now defunct merger with T-Mobile that was going on at the time). The hardware was there, but AWS was simply not enabled in software. Hacks to make AWS work on these phones just enabled the software side for what is already supported in hardware. Without the hardware already being there, no amount of radio flashing will create support for frequencies not already there.
Its possible that some bands are "hidden" in the same way that AWS was for the Skyrocket. Lots of folks here on T-Mobile are hoping the same AWS support is possible on our phone. But if the hardware is not already there (such as for different LTE bands, as you are asking for), you can't make it happen by flashing radios. In the case of AWS, AT&T had a reason for including support (T-Mobile merger). They don't have a reason for including support for LTE bands willy-nilly, just for the sake of doing so, without any tangible (monetary) reason.
Hi,
Blaze 4G is one of the few phone whose radio supports both AWS and PCS bands (1700/2100 and 1900, respectively). Currently, I am using AT&T network with StraightTalk (PCS band). Here is my question, will new modem version for this phone support the same UMTS frequency bands as the original one? There is a new UVLH5 radio available for ICS. What is practical difference between UVLB7 and UVLH5? I really need my phone to support American PCS, AWS as well as European IMT, as I use my phone there too.
Thanks!
Well, seems like the new UVLH5 modem support same frequency bands as the original one. I tried swapping AT&T sim with T-mobile sim, and they both worked fine (HSPA). I still do not know what is different between the old and new modems - I did not notice any difference. BTW, new ICS modem works fine with GB rom.

i've noticed this as well. they seem completey cross compatable and i havent actually noticed ANY difference at all between any of the 3 versions.
im also using mine on straight talk, att sim, and it work great. maybe even better then the at&t moto atrix i have on straight talks att sim.
as for working in europe, i couldnt say, but if you are willing to provide the plane tickets i will gladly fly over there with my blaze and check for you.
They fixed 911 and call echo issues between the first two, as for the uvlh5 it was just minor bug fixes. I was wondering myself if there was any way to use the radios in the t989 list. They can use ours, so shouldn't it go both ways?
