[Q] got a question - EVO 4G Q&A, Help & Troubleshooting

i know this is the wrong section, but the guys in the ATT section aren't as smart as you guys.
i have a motorola atrix from ATT which is gsm, but motorolas web site says phone is ===
NETWORKS4
WCDMA 850/1900/2100, GSM 850/900/1800/1900, HSDPA 14Mbps (Category 10) Edge Class 12, GPRS Class 12, eCompass, AGPS
and sprint is wcdma so is there a way i can use this phone on sprint, if so what will i need to do ?

No, ATT is a gsm network, sprint is a cdma network. Cannot cross the two.

but specs. says it's dual network, what does that mean ?

WCDMA is the 3G technology used in the US by AT&T and T-Mobile.
WCDMA defined
But the term "CDMA" is also commonly used to refer to one specific family of technologies (IS-95 and CDMA2000) used in the US by Sprint and Verizon Wireless.
CDMA defined

Meaning you could possibly have usage of it overseas, on other gsm carriers on different bands.
You could use the phone on t-mobile because they are gsm, but not sprint, as they're cdma.

ok i knew i'd get the answers i needed in here, thanks guys.

Unlocked TELUS PRO2 does not work on FIDO 3G network?

I bought HTC PRO2 (RHOD500) from Telus. I just noticed that it does not work on fido 3G network. GSM is fine.
If the Hard-SPL for world phone is released, can I use 3G fido network at that time?
Thanks
You can pay to get it sim unlocked now and it will work. Search for tmobile unlock on ebay. I am on Telus and it works perfect.

I knew that, and my phone has been unlocked. I can make phone call without any problem.
However, I can not use it with fido 3G network.
It does not work at all
Hey,
I don’t think its the phone . I have seen this issue many times in the past All your data settings are still set up for TELUS and the CDMA network, It’s not as simple as just unlocking the SIM card to get the data to work you have to go in an re-program the phone. I would suggest finding the Data setting on a Windows mobile device Fido has and just copying those into you Touch Pro 2. (you will most likely need to do this by hand)
Can’t promise it will work as I know some Carriers have certain fields added and removed to fit their needs which messes up the phone when you unlock it to use on other networks.
Wait!!
does this mean the RHOD500 has GSM and CDMA??
--- Does this mean?
1. Buy Telus TP2
2. Unlock
3. Switch to Fido/Rogers
4. Flash 6.1 GSM rom
5. Use 3g?
I think the issue here is that the Telus TP2 has had the 850/1900MHz UMTS bands disabled for some retarded reason. (Seems especially retarded seeing as how they are rolling out a UMTS network running on those bands in a couple of months).
There is speculation that the bands physically exist on the Telus TP2 but they have been software disabled. The other possibility is that the hardware is not physically present to utilize the 850/1900MHz bands that Fido/Rogers use for their 3G data and that the Telus TP2 will never work on their 3G networks (as well as its own upcoming one) but I think that would be a seriously regretful move on Telus' part.
The spec sheet for the MSM7600 indicates that the phone may or may not be capable of using the 850/1900MHz bands, but according to HTC and Telus' specifications it definitely is able to use the 2100MHz bands (which makes zero sense in Canada since nobody will be using those bands for a long time).

This isn't extremely helpful, but
http://web.archive.org/web/20071025232258/www.cdmatech.com/download_library/pdf/msm7600_chipset.pdf
according to that (if I'm reading right) there has to be at least 1 other UMTS band, no configuration is ONLY 2100MHz (the chipset that does only that doesnt do the 1900MHz PCS band for CDMA). But really, I'm pretty much guessing.
Hi I am using the unlocked Telus version on Fido. It's true that you can't use 3G because the phone does not support the required bands. But I still use EDGE. It's slower but better than nothing. Create a new connection and name it Fido. APN is : internet.fido.ca
Username: fido
PW: fido
Hope this helps.

Go to this site, click on the Details button and you'll see that the TP2 supports all of the above mentioned Bands. The bands are all software locked and once Telus initializes the new network (along with WinMo 6.5) they will offer the firmware upgrade to open ALL the GSM bands. It'll just be the question of unlocking the simlock on the device!

I think that maybe you are confusing GSM bands with the UMTS/HSPA bands.
There's a big difference between the GSM/Edge bands and WCDMA/UMTS.
I have been following the subject and there`s no concrete evidence that the 850/1900 WCDMA/UMTS bands are only software.
Where the hell did you get your firmware upgrade information? I've only seen this info given as pure speculation!
If the TouchPro 1 is any indication, the phone might be missing some key components to make it work. In the case of the TP1 it was the amplifier that was missing so it couldn't work even chipset and everything could support it.
(see: http://forum.xda-developers.com/showthread.php?t=420865&page=40)
So while it's possible, until someone does a teardown of the phone and we see all the required component it's simply not possible to say that 3G on a GSM network is possible.
The ONLY indication I have seen that it might support 850/1900 HSPA network is the fact that telus stated that the Tour and Storm will not work on the HSPA network. They failed to mention the TP2 so maybe we can read between the lines:

I have been following this debate on multiple forums.
Based on some information from RileyFreeman, I do think Telus will enable the TouchPro2 for new HSPA network.
Granted, today, you can unlock and use on Rogers, Fido or ATT networks using EDGE, it would be a real poor move for Telus to not have an upgrade path to HSPA.
This is Telus's non Blackberry flagship business device, today, Telus has Enterprise customers testing the HSPA network (likely either PC cards or USB modems). Once HTC releases Windows Mobile 6.5, this would be an ideal time to upgrade the radio's and unlock the 850/1900 UMTS bands.
I can see the 850/1900 bands today, not 100% if they are actually there, also wondering if Telus is also waiting for ATT to release TP2 so ATT can test ROM, Sprint nor Verizon would not have any need to do any regression testing on ROM that supports UMTS bands. Tell tale sign will be if ATT TP2 has same chipset as Telus TP2.
I am crossing my fingers that TP2 will support Telus Canadian SIM.
I agree with you points. By seing the bands you mean in windows mobile band selction settings? If so these are always there.
I highly doubt ATT will use the same chipset as Telus since they use the MSM7600 to support both GSM and CDMA. ATT as no need for CDMA.
Also to support my claim:
ATT is RHOD300 device.
I think Telus is RHOD500 and Sprint is RHOD400 (can't find this info but I know 400/500 are both world phone, so it might be the opposit or something)
Different RHODXXX indicates differents innards.
Bottom line I want a TP2 with 3G on Fido so Im crossing my finders too!
Edit:
http://www.engadget.com/2009/06/04/atandts-htc-touch-pro2-hits-the-fcc/
So that's Rhodium 100 for T-Mobile, 400/500 for Sprint and Verizon (or vice-versa) and 300 for AT&T
Noob mistake on my part I think the Rhodium XXX is FCC ...so why did I think Telus was in there =\
Sprint is RHOD400, Verizon and Telus both are RHOD500.

Well yes, it's down to the cellular network used, codecs used to transmit the data, different frequency and network structure. But in the most absolute laymans terms, GSM has a removable SIM card and CDMA doesn't.
He wanted to know what file to download for his Desire, not a comparative on the different standards adoped by each technology. So I gave him the most basic answer so he could go ahead and install the program to his phone, makes sense don't you think?

2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 900 / 1700 / 2100
here is a little about it
In cellular service there are two main competing network technologies: Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA). Cellular carriers including Sprint PCS, Cingular Wireless, Verizon and T-Mobile use one or the other. Understanding the difference between GSM and CDMA will allow you to choose a carrier that uses the preferable network technology for your needs.
The GSM Association is an international organization founded in 1987, dedicated to providing, developing, and overseeing the worldwide wireless standard of GSM. CDMA, a proprietary standard designed by Qualcomm in the United States, has been the dominant network standard for North America and parts of Asia. However, GSM networks continue to make inroads in the United States, as CDMA networks make progress in other parts of the world. There are camps on both sides that firmly believe either GSM or CDMA architecture is superior to the other. That said, to the non-invested consumer who simply wants bottom line information to make a choice, the following considerations may be helpful.
Coverage: The most important factor is getting service in the areas you will be using your phone. Upon viewing competitors' coverage maps you may discover that only GSM or CDMA carriers offer cellular service in your area. If so, there is no decision to be made, but most people will find that they do have a choice.
Data Transfer Speed: With the advent of cellular phones doing double and triple duty as streaming video devices, podcast receivers and email devices, speed is important to those who use the phone for more than making calls. CDMA has been traditionally faster than GSM, though both technologies continue to rapidly leapfrog along this path. Both boast "3G" standards, or 3rd generation technologies
also known as CDMA2000, is CDMA's answer to the need for speed with a downstream rate of about 2 megabits per second, though some reports suggest real world speeds are closer to 300-700 kilobits per second (kbps). This is comparable to basic DSL. As of fall 2005, EVDO is in the process of being deployed. It is not available everywhere and requires a phone that is CDMA2000 ready.
GSM's answer is EDGE (Enhanced Data Rates for GSM Evolution), which boasts data rates of up to 384 kbps with real world speeds reported closer to 70-140 kbps. With added technologies still in the works that include UMTS (Universal Mobile Telephone Standard) and HSDPA (High Speed Downlink Packet Access), speeds reportedly increase to about 275—380 kbps. This technology is also known as W-CDMA, but is incompatible with CDMA networks. An EDGE-ready phone is required.
In the case of EVDO, theoretical high traffic can degrade speed and performance, while the EDGE network is more susceptible to interference. Both require being within close range of a cell to get the best speeds, while performance decreases with distance.
Subscriber Identity Module (SIM) cards: In the United States only GSM phones use SIM cards. The removable SIM card allows phones to be instantly activated, interchanged, swapped out and upgraded, all without carrier intervention. The SIM itself is tied to the network, rather than the actual phone. Phones that are card-enabled can be used with any GSM carri
The CDMA equivalent, a R-UIM card, is only available in parts of Asia but remains on the horizon for the U.S. market. CDMA carriers in the U.S. require proprietary handsets that are linked to one carrier only and are not card-enabled. To upgrade a CDMA phone, the carrier must deactivate the old phone then activate the new one. The old phone becomes useless.
Roaming: For the most part, both networks have fairly concentrated coverage in major cities and along major highways. GSM carriers, however, have roaming contracts with other GSM carriers, allowing wider coverage of more rural areas, generally speaking, often without roaming charges to the customer. CDMA networks may not cover rural areas as well as GSM carriers, and though they may contract with GSM cells for roaming in more rural areas, the charge to the customer will generally be significantly higher.
International Roaming: If you need to make calls to other countries, a GSM carrier can offer international roaming, as GSM networks dominate the world market. If you travel to other countries you can even use your GSM cell phone abroad, providing it is a quad-band phone (850/900/1800/1900 MHz). By purchasing a SIM card with minutes and a local number in the country you are visiting, you can make calls against the card to save yourself international roaming charges from your carrier back home. CDMA phones that are not card-enabled do not have this capability, however there are several countries that use CDMA networks. Check with your CDMA provider for your specific requirements.
According CDG.org, CDMA networks support over 270 million subscribers worldwide, while GSM.org tallies up their score at over 1 billion. As CDMA phones become R-UIM enabled and roaming contracts between networks improve, integration of the standards might eventually make differences all but transparent to the consumer.
The chief GSM carriers in the United States are Cingular Wireless, recently merged with AT&T Wireless, and T-Mobile USA. Major CDMA carriers are Sprint PCS, Verizon and Virgin Mobile. There are also several smaller cellular companies on both networks.

Exactly right. And to my understanding, EVDO has theoretical lower data speeds than GSM 3G.
So does this go for all CDMA phones...Sprint and Verizon? Do they use the same 3G bands so (theorectically) a Verizon 3G phone should work on Sprint 3G?

Yeah, but you have to know someone that works at sprint.
if you know someone at sprint get them to activate your phone's serial number on the sprint network. Something sprint frowns upon, and most local stores wont do it for you. But yeah its possible, just not worth the effort.
It would be easier to get on metro pc's network then sprints

Thanks for the help!
Yeah, when I used to work for [well-known retailer redacted], it was really easy for us to do with the automated system--but that was back in olden days, when a tri-mode phone (on VZW) was a Feature. When I later worked for [different well-known retailer redacted], it was still possible for us to do it if we could get in touch with cooperative sprint reps, but it wasn't nearly as trivial.
More recently, talking to one of my acquaintances who currently works in mobile retail (ha!), I got the impression that it was sort of like the iPhone on T-mo was--they've been hurting for so long that they're willing to look the other way, even if it's officially frowned upon.

Is my Galaxy Nexus SIM Unlocked?

Sorry, this question has probably been beat to death.
Is there a way I can verify if my Galaxy Nexus is SIM unlocked without putting in another SIM card? I don't have any other SIM available to test.
I got my phone from Telus with a new contract. The model shows GT-I9250TSDTLS and UPC is 629018066749.
I've read numerous reports that Galaxy Nexus in Canada comes factory unlocked. I was hoping I could verify before heading off on my trip, and making an unfortunate discovery.
Cheers,
jasphair
I'm not familiar with the Telus network as I do not live in Canada but it is my understanding that pretty much all carriers around the world lock the phone to their own network. This of course can be corrected by rooting then flashing 'universal' firmware on it.

I think it may be unlocked to Canadian carriers - I put a Rogers SIM in my Bell device and there was no request for a network unlock code - but when I went into fastboot mode the screen indicated my device was locked so I unlocked it using the Galaxy Nexus Toolkit. By the time I got drivers installed on a computer I was so frustrated that I chose the easy way.
you guys are confusing the locked bootloader to sim lock. they are two different things. unlocked bootloader allows you to flash roms, unlocked sim allows you to use sim cards from other carriers.
correct me of im wrong here but all north american gnex are sim unlocked. I've read here some people that have the UK gnex are carrier sim locked.
I'm pretty sure my Nexus is unlocked so yours should be too
All CDN carriers have unlocked GNs. A few countries abroad have SIM-locked GNs.
I don't know about Canada since i'm living in Norway, but if you get a new contract which subsidize the phone to make it a little cheaper they usually sim lock the phone.

HSPA is a UMTS technology. UMTS networks are designed to be compatible for mode-switching with GSM, but they are fundamentally different technologies.
If you take a phone that has all GSM bands and no 3G support, and you insert a Bell or Telus SIM, you will get no signal. Therefore they are not GSM networks.

To put the argument to rest, 3GPP Sepcification:
The term "3GPP specification" covers all GSM (including GPRS and EDGE), W-CDMA and LTE (including LTE-Advanced) specifications. The following terms are also used to describe networks using the 3G specifications: UTRAN, UMTS (in Europe) and FOMA (in Japan).

Bell and Telus do not have GPRS/EDGE networks created, hence phones are not backwards compatible on those networks, you *must* have UMTS coverage to have a phone conversation if you have one of their SIMs. This however does not change the fact, UMTS is a third generation GSM technology.

To put the argument to rest, 3GPP Sepcification:
The term "3GPP specification" covers all GSM (including GPRS and EDGE), W-CDMA and LTE (including LTE-Advanced) specifications. The following terms are also used to describe networks using the 3G specifications: UTRAN, UMTS (in Europe) and FOMA (in Japan).

The quote says nothing of the sort. The paragraph you have quoted says that GSM and UMTS are both 3GPP specified technologies. It does not mean that UMTS is a "GSM technology". It is needlessly confusing to refer to UMTS-only networks as GSM. If a network does not support a GSM-only device, it should not be described as GSM, end of story.

Feels like an academia perspective.
To the average consumer GSM means that that it uses a SIM. Another example is the use of 4G to mean a certain speed, yet none of today's phones are 4g phones.
I guess the question is, are we discussing real world or academia?

If you like, I can keep finding references:

What you are confusing is GPRS with GSM.
GSM is an umbrella standard that incorporates many different techs, INCLUDING GPRS/EDGE (2G) and UMTS/HSPA(3G).
It's the difference between saying that all poodles are dogs vs all dogs are poodles.
What you are trying to say is that Telus and Bell do not support GPRS/EDGE which is correct. They DO support HSPA/UMTS which is in the GSM standard.

[Q] Spring LG G2 or GSM G2

Hi All,
I bought a Spring LG G2 and planning to use my AT&T SIM Card on it. I have gone through lot of threads in this forum (Great info and detailed explanation) and it looks like i can SIM Unlock this Phone and make the AT&T / T-Mobile SIM working with out any Issues.
How ever as the hardware bands are not there it's not possible to get LTE on this Phone with GSM Carriers. (Please correct me if i am wrong). If that's the case why SIM Unlock this phone and use a GSM SIM Card instaed of getting AT&T or T-Mobile version of the same Phone ? (It it because of the price difference ? Sorry for asking this as i am not sure what i am missing here).
Does Spring version of G2 has additional benefits that are not available in GSM version of G2.
Thanks

The sprint verzion supports these bands "GSM 850/900/1800/1900 MHz" and other umts and lte bands
The unlocked supports these bands "GSM 850/900/1800/1900 MHz" and other cdma lte umts bands
The difference is you get more bands on the unlocked version. The sprint version is the gsm model and it does support lte. Look up the technical specs on the lg site. look on xda more and see how people fair with lte. if you want to be safe just get an unlocked phone and scrap your sprint model.
Thanks a lot ..
