IS it possible to change the band of a phone? - General Questions and Answers

i have a Samsung Epix (i907). all i need to know is, if it's possible to change the band in this phone, or any phone for that matter? this phone lists tri band (850/1900/2100) and quad band (850/900/1800/1900). i know that this phone as-is, isnt usable on t-mobiles US network, as tmobile's 3G uses 1700mhz uplink and 2100mhz downlink. so its missing the vital 1700mhz feature. so can i download a radio for this phone? or would i have to actually physically change hardware out of the phone? and if i were to physically change hardware out of the phone what would be compatable so that it would be usable on tmobiles 3G network? any info will be greatly appreciated thanks!!

3G HSPA 2100 band hardware based or software? Can it be changed...

Hello,
I'm curious to know is the 3G HSPA 2100/1700 frequency hardware based or software?
For example can one change the frequency to point say at 850MHz?
I'm currently with Rogers, and their 3G network is not on the same band.
Thanks
Nah, its a hardware restriction. Tmobile did this because 2100-1700 are dedicated 3G pipelines. They device does not have 850 or 1900 wcdma only 21-1700
http://www.phonescoop.com/phones/phone.php?p=1763
this is so it can not be used on at&t 3g.
if i remember correctly 1700 is for d/l and 2100 is for u/l
i dont know much about phones....or the various cellphone network types.
But isn't a frequency a frequency? Wouldn't it be the softwares job to interpret the data on the various frequencies?

True, software could interprete the singnal, it just wouldn't be as efficient.
The easiest comparison I could make would be video enconding on a PC. You can have your PC encode a video in h.264 it will just take a while. Meanwhile your HD-DVR is doing the same thing in real time. The difference is the dedicated chip in the HD-DVR that only does h.264 encoding.
I have no idea if there's a way to get the raw signal from one of the other radios, let alone if there's enough power in the G1 to interpret it without the chip. I'd guess not on both cases.

Nice comparison... but I think it is more like a wireless router. A 802.11b router can't use 802.11g... why not they run on the same frequency? Because it isn't just the frequency you have to look at. G takes a different amount of power than B. Same with the different bands. 2100 take a different amount than 850.
If you really want to see a comparison wiki radio frequencies and you will see why cb radios and those little walkie talkies don't work on all frequencies too. There is a lot more to it than just telling the radio to go up or down a couple numbers.
Nope
Qualcomm 7201 Chipset and Baseband is fully Compatible with 850 / 1700 / 2100 / 1900 Bands
You just have to have additional Component on the Board to have additional Support
Please see the motherboard Diagram its Self Sufficient i think.

I thought it was GSM 850 / GSM 900 / GSM 1800 / GSM 1900 WCDMA 1700 / WCDMA 2100
Is GSM 850 the same as WCDMA 850?
But it looks like you answered two questions with that post... someone else was looking for pics of the phones insides. Good job finding those.
Its all hardware based and will not work on at&t 3G. The phone does not have the hardware to pick up 850/1900mhz frequency. Tmobile did this not to screw people over but because they have no need to. The phone was made for T-mobile there is no reason to support at&t bands.
Just like everyone said, it is a hardware thing. As far as I know, since T-Mobile got the short straw and got the 1700MHz band, there really isn't a "universal" phone now that can operate on all GSM and all 3G frequencies worldwide yet. Manufacturers would have to have like 9 total bands supported and with the trend towards smaller and smaller phones, it's something that gets cut early. So the short of it is this: expecting the G1 to work on AT&T's 3G band is a lot like expecting an FM-only radio to pick up AM signals.....or exactly like expecting an American FM radio to pick up all the FM stations in Japan (which uses a wider FM band.)
But keep in mind that the 1700/2100 numbers don't refer to a specific frequency, but a band of frequencies at or around the number. If you've ever used a shortwave radio, you know that they use terms like "the 11-meter band," which is a range of frequencies with a wavelength of around 11m. Luckily, the range of the 2100MHz band that T-Mobile USA uses overlaps the European band enough to make the phone work over there.

If I'm not mistaken, the Tilt was released before the 1700MHz band was a reality.

Once created, you will have a shortcut on your desktop for "Phone Info". Click the "Phone Info" Shortcut and press the menu key. Then click the menu option "Select radio b..." From here you will have the option to change your radio band:

My phone is locked. I can't use my AT&T SIM. Sorry. But when I switch to different bands, I do loose my signal until I switch back.
I have a friend who builds small electronic devices. If I had a damaged tilt would it be possible to remove the 3G antenna and a few resistors and replace the ones in the G1 to make it work on the ATT 3G bands?
Does anyone know enough about the board construction to know what would need to be replaced?
I did use that activity to change the band to get it to work with my provider here in the United Arab Emirates. The thing is I honestly don't know what they are using, publishing reliable info is not a strong point of the operators around here. I grabbed that of a web-site:
The Middle East operators are using the primary 2.1 GHz band for the UMTS/HSDPA operation. Not too precise eh.
I used the Japan labeled band.(?)
sim unlock GI via 611
I was on the horn with CS anyway and figured it would be worth a try to ask for an unlock code request for my G1, they dont have the magic keygens at the Tmob secret base, they have to request it from the OEM, back in the day they gave them out but after many public keygens they got a bit pickier about who get the keys to the liquor cabnet.
when mine comes Ill get an at&T prepay bump sim and mess about a bit just to prove it wont work, and to everybody else ...CALL 611!! ask them for the unlock code tell um you go back and forth to Europe or Iraq or Pagopago, I may not be necessarry but I always have a bit of fun with the story, it used to be a email system send imei to "[email protected]" and get your code in a few days, the good ole dayz

The Menu is shown as the Chipset Qualcomm 7201 actually supports These Bands, But it Require Radio RF/TS Unit to Actually Push Radio Frequcny via Internal antenna. Seeing the Board Picture it only have 1700 and 2100 RF Units. So even is Chipset is compatible it can not Push the Signal or Received Signal other then it is made for. I think in Future then can alter some Hardware and make it more compatible.
So, I'm wondering if I had a broken tilt with the 850 transmit antenna chip in it if I could have that antenna module removed and put in the G1 would that be all that is needed to work on the ATT 3G network?
Anybody, know if that might work since the chipset seems to support the frequency?
I can't afford to pay more than $175 for my phone. I'm a long time ATT customer and can't/won't change carriers. So, I'm trying to get one off of Craigslist or Ebay for about $250.00 or $275.00.
If anyone knows where I can get one for that price please let me know. If I can get one I'll try the antenna replacement idea.

Telus TP2 Radio Question

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.

US Cellular TP2 works with ATT 3G?

As the title reads out, I was wanting to know if the USCC TP2 will ever work on 3G because Edge is getting a little slow... I have seen the "G" up on my bar before but quickly goes away, so that leads me to believe that it could be possible.
Also, I heard that hardware is compatible with the 3G network. So please, could someone that knows more into this tell me if anything will work or even MIGHT work?
Thank you so much!

i would also like to know because i just unlocked the us cellular touch pro 2 for use on att. but when i try the internet it just says dialed 777 failed
Hey, in order for that dialed 7777 error to go away, you need to add ATT internet settings instead of the original carrier settings.
So do this...
Go to your Data Connection options
Add New Connection
Then Put this in for the info:
wap.cingular for the APN
[email protected] - username
CINGULAR1 - password
That should work, of course there is an ATT data cab somewhere, but thats how you set it up manually, I hope this helped!

thanks man i really appreciate. kinda new to this but not really. last windows mobikle phone i had was a touch pro. and i bought an iphone after. BIGGEST MISTAKE EVER. now ive forgotten everything
for some reason it wont go E to G and i cant use certain att features like being on the phone and internet please help

G = Slower than EDGE and nothing to do with 3G.
You're not going to get that phone to work on ATT 3G/UMTS. The band support simply isn't there.

Based on phonearena's tech specs though the TP2 cant even reach full 3g on verizon's network. Here is the link to some verizon phones:

The phone has 3g capability, it is not accessing the full power of the network due to hardware though. If AT&T nerfs their non-iPhones to EDGE then that is what you will max at. If you look at the palm pixi or pre it has faster data speeds because of the hardware. In other words i'm not really sure if faster speeds are capable (due to hardware restrictions) and on AT&T i'm even more unsure because of how their apple contract is structured.
Ah that sounds really crazy! Lol, I wish things were simple. And now, I am noticing my Multimedia Messages aren't going though, I am not sure what that is from though. Anyone have a clue on that?

What are you talking about? The CDMA TP2 can very well reach 3G speed (EVDO Rev A) on Sprint and Verizon. It'll also reach 3G speed on European WCDMA/UMTS networks. The ATT TP will reach 3G speed on ATT and European WCDMA/UMTS networks.
The statement above doesn't make any sense.

All that's required is that you use a version of the phone on a network with a compatible band. The ATT, TMO, Sprint, VZW, etc. TP2s will all reach 3G ontheir respective networks with no problem. When used on other networks the phones may or may not have support for the 3G band used by the network. If it doesn't have the band support then it's not going to work.

Please stop making stuff up. This is absolutely not true. The TP2 is not "nerfed." You just need to use the correct model (ie ATT version) on ATT if you want 3G on ATT.

It is simple. Stupid simple.
If you want 3G you buy the version of the phone that supports the 3G band that your carrier is using.
As far as MMS, you need to make sure that your account is data enabled and that your phone has the data settings for your carrier loaded.
I found a cab that worked for my ATT MMS settings, that was no problem, but like I stated, I have a US Cellular TP2, so it is not a Tilt 2 (ATT) or I would not be posting in the CDMA section of the TP2 forums.
As far as I know the US Cellular device (TP2) has the hardware requirements of ATT 3G network, and I am asking why will it not work up to 3G speeds? Only thing I could think of is that there is not a specific radio for this yet, or something... because the specs of the USC TP2 does in fact work with the 3G bands of ATT.
So what is stopping the device from connecting to it?

According to all of the hardware specs, none of the TP2 CDMA variants support the 3G bands used by ATT. It will not work because it is simply not compatible.
If you want to use it in Europe or Japan, you'll get 3G. But as far as using it in the US on ATT or TMO, you're only going to get EDGE speeds because those are the only US bands that it supports.
The only versions of the TP2 that support ATT's 3G bands are the ATT version and (if launched) the Australian GSM version. The CDMA versions, the Euro version and the TMO US version will not support ATT 3G.

All the specs I read, the Verizon CDMA phone supports Quad band GSM
GSM Quad-band phone capable of global roaming (850/900/1800/1900 MHz)
CDMA dual band (1900/800 MHz)
UMTS European/Asian 3G (2100 MHz)
Does this not cover the 3G bands ATT uses? I thought it was 1900?

GSM = GPRS (2G) and EDGE (2.5G)
UMTS = 3G
ATT uses GSM 850/1900 for 2G/2.5G and UMTS/WCDMA 850/1900 for 3G.
If you use a CDMA Touch Pro 2 on ATT it'll work on 2G/2.5G (since it is compatible) but it won't work on 3G since the band support isn't there.
If ATT used UMTS 2100 it would work.
so will the US Cellular TP2 ever be able to get 3G from ATT network? or will it always be limited to Edge?

So no, the Sprint TP2 won't use UMTS 2100 on TMO US. It'll just use Edge. Now TMO UK (or anywhere in Europe) it'll get 3G because there they use UMTS 2100.
so there is no way???
i was checking ht cell and in the bands it says umts 850 but nothing happens thats too bad. it lloks like im gonna have to buy a at&t one to be able to work

Changing Radio Frequencies

I know I've asked this before but i've never got a solid answer. Can I change the Radio frequency or add it to what the phone is capable of doing so I can hook onto Telus's new HSPA network and not worry about them catching on to what i'm doing?
No, you can only use a phone on frequencies which it has hardware for. If it is not equipped for the HSPA radio frequencies...... you cannot use it.

Then explain to me this. The frequencies this phone is capable of doing according to the telus website are:
3G EVDO Rev A (800/1900 MHz)
UMTS/HSPA (2100 MHz)
GSM/ EDGE (850/900/1800/1900 MHz)
This means my phone is capable of doing it. That means the frequency control is completely software. That being said I should be able to change it so the frequency can include the 2100 MHz as well. The only reason my phone doesn't right now is cause it's about 6 months older than the hspa network and on the CDMA system.
But if it is all software controlled I should be able to do both. Is my logic wrong on this??
Is this against the rules or something is that why people won't talk about it? Cause it's can't be impossible. If no one wants to talk about it, PM or point me in the right direction so I can know where to start looking.
The HSPA network is gsm not cdma as far as I know. So that means you would have to use a telus sim card to get that network.

If you got any info on that I would really appreciate bought mine like 2 month before HSPA launch
according to telus's website they dont support 3G on the TP2, so if its blocked on their end there isnt much you can do on yours

I'm not 100% sure if thats true. But I'd still like to try and see if it's possible. If not least I tried. If it works...

well either way youd need a sim card, and youll probably have to get that from telus, so call them up and ask
Exactly what I said. You need a correctly programmed Telus sim card since their 3g network is gsm

[Q] Touch Pro on T-Mobile 4G

I've got the Touch Pro (T7272-unlocked not t-Mobile branded) and am a T-Mobile customer.
Does anyone know if this device works on the T-Mobile 4G network?
If so, what setting, if any, need to be changed?
The package says the phone supports HSPA network, but T-Mobile's is HSPA+.
The phone will work, but I believe only on EDGE. The radio bands are wrong to get 3G or I guess 4G. There's nothing you can do about it.
Thanks for your reply.
I've used it for years with EDGE, which is brutally sloooooow.
I was wondering what spec determines if a phone will work on T-Mobile 4G network?
that is correct. att's 3/4g opperates arround 1800hmz while tmobiles 3/4g opperates around 1700mhz to no matter what you do (outside of switching carriers) there is no way you can opperate outside of edge

Rastin,
Thanks for your reply.
Is there any possibility that a software solution could change the Band Frequency?
Unfortunately it`s imposible.
