Changing the CDMA Radio

I just got off the phone with Telus and what they told me is that they are releasing ANOTHER TP2 on the GSM network and that I would have to buy another phone TP2 just to get onto the GSM network.
This being said, is there any way to modify the radio signal in my CDMA phone to read both CDMA and GSM, or atleast get more speed out of my phone for connectivity to the net?
*update
I just got off the phone with HTC and the lady I spoke with told me, that to change the radio frequency I just had to change the ROM. That being said IF, I put a Telus HSPA ROM on there the phone should be capable of working on the network. Now that being said. If this is possible would it not be possible to run on both networks, CDMA and HSPA, making the signal control software dependent, meaning I have CDMA controls for standard phone calls and HSPA for running the highspeed network?

Update in previous post.

Eazy, just HardSPL and security unlock your radio bro...Only then you can use the GSM networks in your country (I'm guessing it's US)
But you can only activate one at a time. Either GSM only or CDMA only..CMIIW..
Just my 2 cents

Actually it's Canada
Right but if I unlock the phone, and switch it back and forth on and off the networks, how would that affect my account, could I hide the fact i was doing this?

I have this phone on Telus...I got it unlocked and I put my work sim card in this phone and it's on rogers. I switch networks when necessary....If you get a Telus sim card you would be able to use it GSM.

You should be able to pick which network you use. I saw it in phone settings, I think.

TELUS does not provide GSM at all. They are CDMA and UMTS.

So does this mean its possible. If i have a CDMA Sprint HTC Touch pro 2. That i have the potential of using it on At&t in the US?? All i have to do is unlock it?? Any information would be greatly appreciated.. Thanks!!

And if one does unlock a radio on said Telus phone, can one use both radio frequencies, thus enabling both CDMA and HSPA frequencies?

So Telus new 3G network is not GSM? It does have drop down menu showing "Send SMS over" GMS and CDMA. GSM is selected by default.

Web Surfing while Talking

I know this is an odd request, but is there anyway to use the internet while talking on the phone. Normally I wouldn't care but I'm tired of the iPhone goons hassling me about it since those new commercials.
If not would there be a way if I unlocked my phone for GSM so I could talk on one frequency and surf on another?
Please direct me to a link if this has already been answered, I searched and didn't find anything.

Whoo boy, the old GSM vs. CDMA debate. No to your first question; it's a technology limitation of CDMA, which is why AT&T loves flaunting that fact. GSM also has the leg up in the number of simultaneous connections for conference calling. If you're looking for ammunition, CDMA generally enjoys better penetration of structures, and I know that I have found my service on Sprint to be stronger and much more reliable than my old plan with AT&T. Some people would even say that CDMA offers better call quality than GSM, but that's a huge debate with opinions on both sides. Also, GSM's encryption method was cracked recently, making calls potentially more vulnerable to eavesdropping. Finally, even when I had my old Tilt on AT&T I don't think I did too much surfing while talking on the phone; I really don't think it's as amazing a feature as they make it out to be.
For your second question, the CDMA Worldphone edition Touch Pro 2 used by Verizon and Sprint does have a GSM radio, but the question has been asked before if both networks can be used simultaneously and I believe the answer is always no. Anyone else feel free to correct me if I'm wrong.

last I checked in order to use cdma/gsm phone networks at the same time can't you just pop in a sim card!!!!!

one word IMPOSSIBLE!!!!!!!!!! GSM and CDMA are hardware radios an unlock is IMPOSSIBLE unless the phone is a world phone with both CDMA and GSM but your phone doesn't qualify so try getting a GSM/CDMA hybrid and then come back to me. However verizon will upgrade to LTE which is GSM based!!!!!!!! watch em LTE will allow voice and data at the same time. When LTE upgrade is complete say goodbye and good riddance to CDMA it will be shut down soon!!!!!

qjsmartphone - I thought that the TP2 was a world phone and thus held both antennas for cdma and gsm?
trogdor1138 -thanks for the input.
now I'm with sprint, and they offer 4G. This may be an ignorant comment, but can't a world phone with both antenna's say call on cdma and use the 4G provided by sprint? Or am I missing something? I kind of new at this so forgive the question if it is stupid. If there is a wiki on it please give me the link and I will be glad to read up. Thanks

I'm not sure what you are talking about, but CDMA variant of Touch Pro 2 does have both GSM and CDMA hardware in them.
Also, LTE and WiMAX is a two new 4G technologies that will eventually replace 3G data.
LTE is not based on GSM, they are two different communication technologies.
Back to OP's question, if you are using CDMA branded TP2 you cannot surf and talk at a same time. It is limitation on CDMA technology.
4G and 3G is not compatible, is your grandparent's old 2G phone do 3G? no.
How about your 3G phone accesing 2G? yes. Usually when newer technology is being deployed, they make sure that it is backward compatible, so that they can lower battery consumption and remain accessible to area where new technology is not yet available.

Just be near wifi and then show them you can surf while talking.

I like the way you think

Or pop in a ATT or T-mobile SIM card and switch to GSM mode. The phone IS capable of voice and data when using GSM.

I'll jump in here...
I thought Sprint/Verizon phones with both GSM/CDMA radios cannot use AT&T nor T-Mo SIM cards. I thought they only accepted the GSM SIM cards of countries outside the US.
Wait... HardSPL fixes that, doesn't it?... Oh well, I think I should stop stalking the CDMA forums when I have almost no idea on anything CDMA-related!
But, I'm still in favor of the WiFi suggestion!

mac people live in their own little world. don't let them bother you. sure, they can talk and surf the web at the same time...if they have 3g coverage. but there are areas where they have no coverage at all let alone 3g. then they can use the 'paper weight mode'. i also love how they tout their app store meanwhile we've had multiple wm app stores for years already. also i get to choose what apps i want to use without htc or sprint telling me what i'm allowed to.

i think you can use any SIM card you want if you phone is SIM Unlocked

yes you can use any sim card if your phone is sim unlock buy the Sprint TP2 is not working with us 3G

unlock
I called up VZW and told them I was going to Europe and wanted to use prepaid SIM cards instead of paying Big Red the $$. They gave me the SIM unlock code and now I can use T-Mo or AT&T SIM cards with no problem. Only downside is that their GSM frequencies are slightly off from the rest of the world so no high-speed data when using VZW on GSM carrier in the states...

The Verizon TP2 has a simple SIM lock on it which is similar to standard GSM SIM locks. Remove the SIM lock and you can use any SIM card with a compatible network, including US networks.
The Sprint TP2 doesn't have a standard SIM lock, but instead has the US frequency bands disabled. Hence the need for a new radio.

Telus Milestone problem with 3G

Hi,
I just bought a Telus Milestone while in Canada las week, I bought it from a Best Buy store in Toronto.
I live in Costa Rica and we use 850mhz 3G band but for some reason is not picking up 3G band only GSM with EDGE data connection.
I already try the "WCDMA only" option but still not working it goes out of service.
Is there anything different in Telus 3G network that could be not compatible here?. All of the iPhones 3G and 3GS work here with no problems, same as some other ATT phones.
According to the FCC my phone supports 850mhz 3G band.
Behind the battery it says: FCC IHDP56KC5
And according to FCC documentation it supports WCDMA 850/1900/2100 plus HSDPA 10.2 mbps
So, I don't know what's going on...
Hope somebody can help me, I heard there is a Field Test hidden option on the phone that can show some troubleshooting information, but I don't know how to access it.
Thanks for the help,
Luis

Planning to buy one too, so it'd be handy to know what's going on there. I take it you bought it unlocked? Also, is the APN and all that setup correctly? How do you have it setup, is it one of the new 3G phone lines or an old GSM one (which are capable of 3G as well)?

I have the exact same problem down in Mexico, I just received an unlocked Telus Milestone and all I get is edge. I am using the same APN configuration that I have on my Rogers Dream (G1) and I do get 3G on that one.
Also, I believe this forums are for HTC phones only, I'm not sure we'll get lots of help here on a Moto issue.

Mine does work on HSPA+ here on Telus.
Just a hypothesis would be: Since it has only been released on HSDPA/HSPA+ network in Canada, they haven't done proper testing on 3G mode and there is a bug in 3G only mode.
Like I said, I can't say for sure since the only other GSM network we have here is rogers which is mixed 3G and HSPA+.
On second thought, I do have a Fido/Rogers SIM lying around so I'll give it a shot over the weekend and let you guys know.

Thanks Ady, it does sound like a compatibility issue. I have tried Telcel, I should be able to try ATT in the US next week.
Other than the 3G issue, this phone very darn nice... way faster than the dream, Multitouch work's great ont the browser.

yeah, its really good.
Update: I gave fido a try and it seems to be working, but on HSPA.

I bought it locked to Telus, and got the unlock code from "UnlockMotoDroid"
My SIM card is one of the old GSM ones, but I already try the new 3G SIM Cards (kolby3g) and same problem, only EDGE data connection. APN and all that is correct.
pasker17, I'll love to hear if you find a solution. Keep me posted.
Ady, agree with you, other than the 3G issue, this phone is pretty awesome..!!! Hope I can find a fix soon. I'm wondering if this could be related to the HSPA+ advanced technology that might not be compatible here, but as far as I know it should be backwards compatible with any other 3G technology.
And also, I heard people is using it with AT&T no problems, 3G data speed. Do they have HSPA+ ?
Thanks for your help guys

AllI can tell you guys is ther eis something diffrent with Radio signal we are using here ( Canada ) and the one in South America, I been tryin to use Latam f/w on my stone and no signal aty all whatsoever , so th eother way around doesnt work , they must be something we are missing about network compatibility , 1 thing I am sure Telus 's 3g network is the new HSPA .

double post sry .

DAG,
Yes, maybe there is some sort of advanced HSPA+ network in Canada, and that might be the reason is not working in some other places.
But as far as I know, all those HSPA+ flavors, should be backwards compatible.
Now I wish Motorola frees the bootloeader and I can try it with some other custom ROM.

That wouldn't be it. If you the iPhone works in Costa Rica the Milestone should work.
Have you called ICE? From the very brief info I can find on how to get the iPhone to work in Costa Rica it almost appears that ICE itself has to approved the devices on its network. Apparently they have approved the iPhone. I assume they'd do it via IMEI

Yes and no, you do need to provide an IMEI to get your data plan working, but it should work with any device. I did it when I had a 3GS and have used my SIM on other phones and 3G works normally when setting my old apn. This is indeed bizarre

I called ICE, and went to their offices. Milestone is not
in the "approved list" so they won't even take a look. Same with the iPhones they work fine but are not "approved".
They already got my Milestone's IMEI registered on the system.
At the end they told me that this could be a software incompatibility but since the phone is not "in the approve list" there is nothing else to do or test for them.
Since this phone for sure supports 850mhz 3g band, I'm starting to think that it could be a software thing.
I'll be in the US in a couple of week and will try to test it on ATT, I heard a lot of people are using Canadian Milestone there with full 3G speeds

I take it you've tested known-working SIM cards and all (not only Kolbi ones), I know for a fact that mine works with APN: icecelular, if you care to give it a try with mine, let me know and we can arrange something. I really want to buy a Milestone and want to know if it works with 3g here or not

I've tested GSM Sim Cards (green and pink) and kolbi3g SIM cards, all of them with data enabled, not of them works with 3G data speed only EDGE.

I just applied the Barazilian update to 2.0.1 and my radio baseband was changed. And now I can get full 3g data speeds and I have an "H" symbol on top

not getting a signal abroad

I am currently in Japan with my htc inspire and I am not getting any signal at all. I tried resetting and going into the settings menu to change the "network operator" but its greyed out.
does anyone know what I am doing wrong? I desperately need it to work here and I have the international plan activated on my account.

Well in Japan you wont get 3g due to Japan using 2100mhz and The Inspire does not have that freq built in. You should get a call signal. Make sure you enable international roaming on your account. Or if your phone is unlocked buy a local sim card and pop it in.

I enabled international roaming on my account and have the $6 plan added for cheaper international roaming service.
I don't need 3g, just a phone signal to make calls and receive texts. but all I get is a "x |on top.
I have travelled to countless countries with my other unlocked phones and have never had a problem with my phone not picking up a signal.
is it possible that because I changed to a 3g sim card, it doesn't work abroad?

japan does not have gsm EDGE coverage i dont believe. they do have 3G HSDPA, but on 2100mHz, which the inspire does not have. so you are kinda out of luck i'm afraid.

Verified with AT&T's tool here
http://www.wireless.att.com/travelguide/coverage/roaming/step1.jsp
The Inspire doesn't get voice or data in Japan

Had the same problem in Korea last week - sucked big time. How can they call it a world phone and leave out 2100!!!!

That is absolutely terrible and false advertising since Japan and Korea re left out which are huge territories. I also have an unlocked samsung vibrant that I need to charge to see if it works.
Does anyone know if the vibrant has the right frequencies for Japan?

According to the same tool I previously posted, the Captivate will work in Japan and South Korea
Edit: Oh, Vibrant... hold on
Don't know about the Vibrant, does it have the 2100 frequency? If so, then probably yes

Yeah I still can't believe this phone left out the 2100 frequency. I posted about this a few weeks ago and still can't believe I didn't notice that it didn't have the 2100 when I bought it, as I travel to Japan quite often.
I don't like the Atrix and the Infuse 4G isn't out yet so I'm just waiting it out until some better phones come out and will just use a older phone in the interim. Those both support 2100 apparently. Kind of ridiculous that HTC left it out of this phone.
Just did a quick search and it looks like the Vibrant does have 2100 UMTS support.
Sprint CDMA works in Tokyo (and possibly Verizon). Not sure what carrier it uses but it does work for voice only. Probably not much help though.

[Q] stuck on 2g...wont go 3g...why?

So I I've searched for an answer or a problem similar only to come out with no luck...do what's going on right now is that I got my inspire unlocked from att and came to India because I now have to live here because in going to college here..anyway its unlocked and I purchased a prepaid plan from company Vodafone.
So I've been running with 2g for some time now and now I just sick off it and need 3g so I can also use mylaptop and connect to hotspot. Anyway I've got 3g plan however my phone is constantly staying on EDGE....which is pretty annoying because its so slow and I paid a bit to get 3g upgrade. I've tried the *%*#4636#*#* phone setting and switched to GSM/cdma auto. Also got the smsc and updated. Also I set up a new APN suited for the company with no luck..still on 2B.C. So my question is..how do you switch on 3g on inspire? Haven't been able to find that also been searching it. My Android is still 2.2.1 if that makes any difference. I've also called they company and HTC to no success...so please help me out. How do I initiate 3g on my inspire?
apparently I just need the option to turn on 3g and the phone info thing won't work...keeps me on edge.
Thanks

If you have tried going to your settings then to you mobile network settings. There should be an option to use only 2g networks. If that is checked, then you need to uncheck that.

But that's the problem...I can't find that option.I go into mobile network settings and see data roaming...apn..network operators..and always on mobile network option. I've been trying o find a option to set which to put..for instance 3g only or 2 g only or 3g preferred..no avail. still have Droid 2.2.1 if that makes any difference..

Their is no way to get 3g. India uses a different frequency for 3g. No way to change it outside of getting a different phone with compatible bands

The Inspire radio utilizes the 850/1900 3G bands. India uses the 900/1800 bands for 3G. If you use the phone in a market where the 3G is on a different frequency than the radio in the phone, the best you'll get is Edge. This is hardware related. There is no setting you can change or ROM you can flash that will allow it to operate on 3G in your market.

So no absolute way of getting 3g on my inspire in India?

Nope
..........

Huh...so best bet would be to get a new phone? What should I look for in order for this problem not to happen again?

Get the correct version, The Desire HD.

Is it company -problem or a country -problem? If I switch providrs, will it work?

Doubt it. Pretty much everyone except the US uses 900/1800, and att uses 850/1900 on it's phones (the inspire) - as previously stated this is in the phones hardware. So unless you can find a provider that uses 850/1900 for 3G your SOL - best bet is to get a new phone (DHD uses 900/1800 for 3G and is the same device as the Inspire, very minor differences)

Even i too have the same problem and I am from India.I have tried with my network operators many times but nothing works,i have to pay for 3g data and use 2g.Is there no fix for this issue?

omg, SEARCH. its what you agreed to do before posting.
ill put it simply for you. your inspire will never get 3g outside of the united states.
