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.

What rom, tmo tp2?

I really don't get it. Was wondering what rom goes with USA t-mo tp2? cdma or gsm ones.
I know that t-mo tp2 is gsm but I just dont want to brick my phone.
Going to use it in Europe. And what rom to use as well ?
Thank you

If you have the T-Mobile USA TP2 it's a GSM phone, and if you want to flash a custom rom it should be chosen from the GSM ones.
As for which ROM is best for use in Europe, it doesn't matter.
Edit: I assumed you're talking about an OS-ROM...but if you're talking about a radio-ROM then maybe some work better than others in different locations.
But, as far as I know, the TMo USA rom won't be able to access 3G signal in Europe because its radio hardware uses different frequency/bands for 3G than is used in Europe. It will work with regular GSM bands, though.

A T-MoUSA-branded TP2 in Europe and using a 3G data connection? If that's true, I'd be glad. I'd like the option of high-speed data on my TMoUSA phone while over there...

getting euro hero to work with telus

so are the telus and euro hero the same hard ware wise?
could i install the telus ruu and get hspa on the 1900/850 bands? cuz my antenna can get it, it just takes gsm/egde/gprs instead of hsdpa...
does anyone know where i can find a link to this ruu?
if its not for sure, will i be able to just use my recovery image after?
if not because its an ruu, could someone package the ruu into an update.zip so i dont loose the recovery image in case it goes wrong?
thank you so much!
also to be sure
i thought i could use my phone as it is on telus! In which case,
1. is it possible to be partially unlocked?
cuz i can use rogers but not telus
2. why would telus site say my phone works when it doesnt?
3. how do i check if my phone is unlocked when i stick in a telus card and it doesnt ask for an unlock code!?
4. maybe they havnt worked out their kinks yet?
thanks again

The cpu controlls the radio bands, these are preset, one chip for us radio bands and one for euro, so your radio problem is hardware not software and your stuck with what you got ...... sorry

It's not 100% confirmed about the hardware. But at this time, no quad HSDAP band unlocks

you just got me super stoked... are you saying that the phone might be capable... it just has to be unlocked or something?

you posted this in another forums.. we told you it wont work.. youll be stuck with a 2G phone.
European Hero = Hero100
Telus Hero = Hero130
2 different product numbers, which means.. different hardware. The radios are not software locked, they physically non existant in the phone you have

Switching to Rogers won't help with the frequency issue.
Rogers and Telus use identical bands for 3G/HSPA

Except that he will get GPRS/EDGE on Rogers, whereas he gets nothing on Telus. because apparently they don't have a 2G network, and haven't signed a roaming agreement with a carrier that does.

Yup. GPRS/Edge works on Rogers. And to be honest, 3G data transmission seems as slow as Edge (I've got both a European and North American Hero) at times (a lot of the time). Must be those darn iPhone users sucking up all the bandwidth.

i dont use data anyways so not having 3g doesnt effect mee (using pay as you go)
and whoa they sell sim cards for $40! but i found for 15 just gotta wait like three days for it in the mail :\

Depends where you live, im a tester for Ericsson and i work everynight on Rogers sites, devices are all capped at 7.2mbit and the max you can get out of the connection is close to 3mbit.. its not network congestion its just a softcap set by Rogers to not cause congesting.
i dont know if they are made available to the public, but i use a 21mbit usb aircard for my tests and on Rogers i get 15mbit in montreal.

HTC MAGIC on TELUS.
if i purchase an htc magic unlocked originally from rogers will it work with telus hspa data + phone?

Here's a thought!
If you've a question about the Magic, why not go to the Magic forums and ask it there, instead of posting on the Hero forums where it is just spam?

Ha on rogers maybe, but on Bell 3G speeds on my phone are 4MB/s down, and 1MB/s up.

[Q] Are any other N7 2013 LTE users having issues with specific carrier SIM cards?

Hi all,
While back in the USA, I was lucky enough to get a new Nexus 7 (2103) 32GB LTE model which shipped with a T-Mobile micro SIM card good for prepaid data access plans. However, I live in the Netherlands and when I tried to use my Nexus with a micro SIM from my provider Vodafone, it was not able to properly list the mobile network operators.
I opened a technical support incident with Google Play services who lead me through several diagnostic steps which included verifying that the tablet is not SIM or carrier locked, it properly recognizes the available networks with other carriers SIM cards (worked with T-Mobile USA, Telecom DE, MTN NG, Rogers CA) it also can list the mobile networks with no SIM in the device. But when a Vodafone SIM is added, it simply doesn't recognize any network operators. It's not a matter of APN settings, as we have verified these are correct, but the problem occurs at a very early level in preventing the mobile networks from being listed.
I believe this to be somehow related to the SIM card/middleware used to communicate with the SIM to the hardware. I see this behavior with the LTE Factory Image JLS36C as well as the Cyanogen Mod 10.2 unofficial deb builds.
Are there any other LTE users that are having a similar problem? Without mobile network access, my LTE model is effectively a WiFi only model and I'd really like to get this fixed.

As has been posted quite a few times already, the US and Europe use different channels for LTE. So a US N7 will not work with all European providers and vice versa. Most probably Vodafone uses one of the LTE channels not supported on the US N7. So you have two choices:
1. Find a different provider that uses the channels supported by the US N7.
2. Replace your current US N7 with an European N7 model.

While the US and Europe do have some variance in LTE bands - we confirmed that the bands used by Vodafone NL are as listed below:
Nexus 7 (2013) Tech Specs (LTE)
Network
North America and Japan:
GSM: 850/900/1800/1900 MHz
HSPA+: 850/900/1900/2100/AWS (1700/2100) MHz (Bands: 1/2/4/5/8)
LTE: 700/850/1700/1800/1900/2100 MHZ (Bands: 1/2/3/4/5/13/17)
Rest of World:
GSM: 850/900/1800/1900 MHz
HSPA+: 850/900/1900/2100/AWS (1700/2100) MHz (Bands: 1/2/4/5/8)
LTE: 800/850/1700/1800/1900/2100/2600 MHz (Bands: 1/2/3/4/5/7/20)
Wireless
Dual-band Wi-Fi (2.4G/5G) 802.11 a/b/g/n
We confirmed that Vodafone NL use 4G data enabled in a combination of the 800MHz and 1800MHz bands which are listed as supported.
The fact that my N7 can connect to other mobile networks in Europe with other carrier SIM cards also disproves the need to get a "European" model to connect to a network. There clearly is a problem with the Vodafone SIM and the NA Nexus, but simply blaming it on the channel or bands is not correct. Addittionally, even if the LTE connection is not possible 3G connection via HSPA+ or 2G GSM connection should be possible. The same Vodafone SIM worked with my N7 2013 3G model, which was also from NA, so it is clearly not an issue with the bands & channels.

Have you tried manually changing your prefered network type in testing menu *#*#4636#*#*
Since there is no dialler on N7 deb, I use https://play.google.com/store/apps/details?id=org.freespirit.hms&hl=en
From tablet info submenu, u can also use settings button (3 dots) to manually select radio band

Thanks for the tips regarding the Hidden Menus application. I've installed it and set the GSM/UMTS band to EURO Band (GSM-900/DCS-1800/WCDMA-IMT-2000) but still not had any luck detecting mobile networks with the Vodafone SIM inserted. After removing the SIM and restarting, performing the same operation to search for available networks shows the four network operators in this region. I'm currently in Germany and in this area it shows
E-Plus
o2- de
Telekom.de
Vodafone.de
If I replace the Vodafone NL sim and try the same operation again, Settings | Mobile Networks | Network Operators - it searches for only a second or two (compared to the 15 or so it takes with no SIM installed) then does not show any networks.
All signs point to the issue being with the SIM chip OS or incompatability of the SIM chip profiles with the Nexus 7 (2013) LTE model. I didn't have any issues with this and my Nexus 7 (2012) 3G version.
In another strange hardware related issue, I have noticed that the Nexus 7 (2013) uses a different NFC stack and does not recognize all of the NFC tags that the 2012 model recognizes. A co-worker with the 2013 Wifi only version ordered some NFC tiles but they don't work with either his or my 2013 model, but work with the 2012 model. Very curious if this is somehow related to the issue that I see with the SIM card problem I am having.
Any other ideas?

Did you find a solution?

Unfortunately, I have not been successful in getting this resolved. I've visited Vodafone several times, but none of their in store personnel have been able to give me any other answer than "it doesn't work" and we also see this with North American Nexus 5 handsets. I've done some addditional testing with other MNO SIM cards with American, Dutch, and German T-mobile SIMs and they work flawlessly and with 4G LTE speed, so it isn't a question of network or band.
The issue is definitely related to the SIM card OS and version. However, Vodafone have been unable to tell me what the SIM vendor is and what the chip operating system is.

Vodafone promised a solution
I have AGAIN asked Vodafone for help and they promised me a solution. I have my doubts ad will post an update next week once i hear back from them.

Did you hear anything back from Vodafone? They have simply told me they don't support the device and explain that it is due to a North American device, which is simply not true. I've tested with T-Mobile data card from The Netherlands and also from Telekom in Germany and the Nexus 7 2013 gets 40+ Mbps download speeds on those networks. So the issue is clearly related to the Vodafone SIM cards, but no one has been able to give me any insight as to what card OS they are using, so it is very hard to troublehsoot the problem any further.
Two big thumbs down for Vodafone service & support!

Any news on this problem yet? I have exactly the same problem, I can use a KPN sim but my Vodafone sim simply won't work in my US Nexus 7. This sucks, I upgraded to a multisim Red Super subscription to be able to use my new tablet anywhere without having to tether.
I made sure to check which bands the US Nexus supports and figured in a worst case scenario I would simply use 3G instead of 4G. But it won't connect to 3G either

I have the issue as well. openend a ticket with Vodafone and directed them to this thread. unfortunately they were thus far also not able to solve it yet. hopefully something will happen, as otherwise I will need to drop Vodafone....
I also tested it with a KPN sim which worked perfectly. two Vodafone sims and a duo sim all had the same issue. Real strange thing is that with the KPN sim I was able to see the Vodafone network. But on the Vodafone sim I wasn't able to see any network. They assured my it was not a 4G only sim card, thus it was also strange the nexus did not pick a 2G or 3G network. In the settings though I could not change the 4G perferred setting to either 2G or 3G. it immediately reverted back to the 4G setting....
All in all, no realy help yet, only confirmation of what is being seen above.

In the settings though I could not change the 4G perferred setting to either 2G or 3G. it immediately reverted back to the 4G setting....
All in all, no realy help yet, only confirmation of what is being seen above.

I wouldn't hold your breath waiting on the response from Vodafone. I've had a ticket open for months with them, and it supposedly has been escalated. I've inquired in person with the so called "specialists" and they simply say it doesn't work with their SIMs. Yet nobody can tell me anything about the SIM, like manufacturer card OS, etc. It is really frustrating to hear this as I work with smart card and SIM middleware developers and if we had a bit to work with we might be able to fix the problem on our own.
I was at the end of my rope and extreme frustrated with them and wanted to cancel my contract, but they said that despite me paying for months of service that I haven't been able to use, that I would have to pay the remaining duration of my contract before I could switch to T-Mobile, which I think is total crap.

dual sim same problem with vodafone NL
I have the same issue. I use a dual sim from Vodafone in my Nexus 5 and Nexus 7. The Nexus 5 does not show these problems, but the 7 does. When I buy prepay mobile data abroad (Europe, Asia, US, Australia), the Nexus 7 2013 C works great with e.g. Orange, t-Mobile, Vodafone etc. But as my cellular subscription is a corporate one, at home I have to stick to wifi, for almost 2 years now! (I bought the 7 in Australia about 2 years ago). And yes exchanging sims between the devices does not make a difference. The combination vodafone NL sim + nexus 7 does not provide mobile data.

Not enough info. Need the phone's CID, and what 3G (UMTS) bands used by your carrier.

I Google and found this CID for my phone spcs_001. I got to know this from terminal emulator. Sorry but I don't know what band is used by my carrier.but I recently took 4g sim from my carrier which is working great on my brothers phone but not on my phone。I am using Airtel's 4g SIM and not able to use even 3g on it .

Call your carrier and ask them, they can answer this.
Nobody here can help you, if you don't give this simple information.

Thanks, I have called my carrier and they advised that 2100 for UMTS (3G) and 2300 LTE (4g) band is used by Airtel.

You have the Sprint version of the phone (based on CID) which should be compatible with 2100 MHz (UMTS). This phone does not support 2300 LTE, but you may already be aware of that.
Are you sure your carrier's APN info is entered correctly?
You sure 3G worked for a week? Any changes that happened that could have have changed that?

Thanks for sharing this detail, I was not aware about the 4g which you mentioned. Yes my APN is correct and i have crossed checked with my carrier as well. And yes i have used 3g for a week and after that I took another SIM from my carrier(Airtel) 4g sim and just after that my 3g stopped working.
And I have checked my new sim in another phone so it's working fantastic but not in my phone. and I have checked my brother SIM in my phone so even that sim's 3g is not working on my phone. I could not understand all of sudden what went wrong which it stopped working.

Check the APN again, and that is the currently selected, active APN. All I can think, is that inserting another SIM changed the APN.

I checked again, but still same issue. What should I do any suggestion. Or could this be a software or hardware issue how to know this. Any idea
