euro hero on telus problem!

so, i tried my mothers rogers sim card and my EURO hero works fine. I could not get my newly activated telus sim card to work in my hero though, it has the right bands, there site says it should work too!
does anyone else have a euro hero on telus?
how did you get it working!?
I appreciate any and all help! thank you!
ps i had a rooted hero with modaco 2.9 and my own theme.. but i thought updating to the latest ruu from htc would fix it but apparently it didnt!
also when i go into menu - settings-wireless controls-mobile network settings-network operators-search networks... i only get rogers wireless and no telus.. so i went driving (passsenger seat lol) to see if i just wasnt getting reception... but no matter where i went i did not get service...
also i called telus and they said there network is fine and that my sim card is activated..
my phone has popped up a few times "telus : temp. me error" or something like that too

urghh, i bought an unlocked phone... but i never tried a sim card till after i updated to the newest ruu from htc... maybe its not totally unlocked?
although it works on rogers! but arnt they roaming partners? maybe thats why it works on rogers?
idk im pretty sure bell has the new network too, and they dont show up on my phone either:\
please helpp!

k now i have used flash rec to get the recovery image, installed t-mobile image because the telus check to see if my phone will work said it was from there even though it was "unbranded and unlocked" but when i pop my telus sim there is nothing saying that the network is locked or anything :s
urgh i will try a replacement sim tomorrow hopefully!
still would appreciate any info anyone has!

Does anyone have the europen hero on TELUS or bell?

I hate to be the bearer of bad news, but unfortunately the Euro HTC Hero will not work on Telus or Bell. Telus and Bell's new HSPA networks only work with phones that can support HSPA 850/1900. The North American HTC Hero (sold by Telus) has these bands. The Euro HTC Hero only supports HSPA 900/2100 (i.e. any 3G networks outside of North America). The reason you can see Rogers is because Rogers has GSM support (the Euro HTC Hero can only work on GSM networks in Canada - Rogers or Fido only).
I wish I had better news, but I'm afraid you'll need to purchase a North American HTC Hero (if you wish to use Bell or Telus' HSPA network), or alternatively, another cell phone that supports HSPA 850/1900.

but i read from htc site
HSPA/WCDMA:
*
900/2100 MHz
*
Up to 2 Mbps up-link and 7.2 Mbps down-link speeds
Quad-band GSM/GPRS/EDGE:
*
850/900/1800/1900 MHz
and telus site
Runs on 1900/850 MHz frequency bands and uses standard 3GPP SIM cards
so techinically i just cant get 3g, but i cant even get voice/text working
and im on pay as you go anyways

wait so your saying telus doesnt have anything but hspa and 3g going to their sim cards?
there website even says my phone is compatible! (after referencing my imei!)
it has to woork! i dont wanna use rogers.. even though thats who i originally planned on using before knowing telus was getting this network

It wont work.
timmacnaughton is right.
The euro Hero only has 2100 HSPA bands, which are not used in North America, Bellus uses 850/1900 (same as Rogers) for the HSPA network, however, the reason your phone is working on Rogers is because its on Edge (2G). Bellus doesnt have 2G to fallback on, only a 3G network.
2G bands are considered world frequencies, anywhere you go, if the carrier is GSM your phone will work with 2G, they use different bands but GSM phone are all quad-band 2G ready
So in all in all.. the european Hero will work on Rogers but Edge only and wont work at all on Bellus (Bell & Telus)
The best way to know if another device will work on Bellus, if you come from Rogers is just to see if you can use 3G on it. If your device cannot use 3G on Rogers, it wont work on Bellus.

ohh thats wierd, i thought telus was doing this because of the olympics, and if most people work on 2100, then they wont be able to use telus in which case they wont get the traffic from the olypmics :s

Lol, no.
Roaming contracts have been signed and delt with for a long time. Besides, Bellus's network cant even be used by a euro phone so yeah.
Anything that is roaming GSM will be on Rogers. even US phones, AT&T has a contract with Rogers for roaming.. in fact every GSM carrier has a contract with Rogers, they own roaming in canada for GSM. bling bling?!

HD2 on Verizon?

I'm just curious if there's anyone out there with an HD2 on Verizon? If not, is it possible to do it? The HD2 is a quad band device, so doesn't it have the hardware capable to be on a CDMA network? I was thinking that if I bought an unlocked HD2, I would be able to put it on my account with Verizon. I guess I would have to be running a different radio in order to do that though.
Anyone have any thoughts, comments, suggestions? I really want one of these phones, but I can't switch from Verizon because no other provider gives me 3g in my area. Plus, my Touch Pro 2 is getting dated compared to that 1gz Snapdragon!

HD2 is a GSM phone. Pretty sure it can't be made to work on a CDMA network.

Technology
GSM: 850/900/1800/1900 MHz
WCDMA/HSPA: 1700 MHz (AWS) / 2100 MHz
Taken from the HD2 tech specs on HTC's website.
If it has a CDMA radio, why couldn't it work if it were unlocked?

Does Verizon have a sim card to put in the phone? If not, how can they make it work on their network.

Verizon does have sim cards, they use them in the Blackberry Storm, which is both GSM/CDMA ...
But It may be like the storm if it is activated via the IMEI that it may not require a sim card ...

rly? i never thought verizon would use sim cards...can we bring non verizon phones them from lets say ATT to their network?

Verizon has SIM cards for their GSM/CDMA world phones. Sprint also has world edition blackberries with a SIM card. The SIM card is there so the phone is able to roam onto a GSM network outside of the USA. As far as I know this SIM card will not allow it to roam onto a USA GSM network, since there are no roaming agreements in place between VZ and ATT/TMO
The WCDMA on the HD2 is not the same as CDMA that VZ/Sprint use.
WCDMA is the 3G standard that GSM providers use. CDMA is well as far as i know the same old CDMA network that VZ/Sprint have used for ages with whatever "bolt on" enables 3G on their network. I dont follow the CDMA standard so i dont know all the specifics about the tech.
Edit:
I just did a small amount of wikipedia research. What Verizon/Sprint use is CDMA2000/EV-DO
http://en.wikipedia.org/wiki/CDMA2000
http://en.wikipedia.org/wiki/Evolution-Data_Optimized
This is not compatible with WCDMA,
Even though they both use "CDMA" family of technology http://en.wikipedia.org/wiki/Code_division_multiple_access
WCDMA is a wideband version http://en.wikipedia.org/wiki/WCDMA

Thanks for the replies guys. This is a bummer though. I was really hoping to be able to get an HD2 to use with Verizon. Oh well, guess I'll wait for the Droid X to release, even though I'd like to stick with WiMo.

3G international compatibility

Hi there guys! Now that the phones are finally shipping, can anyone please test the real band compatibility? I want to buy an unlocked G2 and use it here in Italy, but only if I can get at least a fully working 3G connection.
Please fellas, I badly need this info..
Thanks

No such luck chief. The only 3G band on the G2 is AWS. It will only work on carriers like T-Mobile (USA), and Wind (Canada).
The stock Desire Z, however, has HSDPA 900 / 2100 and should work in most non-US countries on 3G, but check your carriers bands first. The downside, Desire Z has 1.5 GB storage, the G2 has 4 GB.

Unfortunately I think you are going to be disappointed. I posted a buzz about this a while back. You can look at page 3 of the test report in the FCC submission. The nutshell summary is that the device will only support Band IV for 3G, or in other words T-Mo US' UMTS 1700. This is unfortunate since I used my unlocked G1 quite a lot overseas, thanks to its UMTS 900/2100.
You'll probably have to go with a Desire Z if you want this device with European radios.

Can't believe it's for real...I mean, the 2-year-old G1 does that...and what about people working overseas?
That's a MAJOR fault from T-Mobile, and it's totally weird to say the least.

Perhaps tmo figures that frequent int'l travelers are a small enough percentage of their userbase that omitting the Band I poweramp was worth the cost savings?

Oh, it gets better. I only paid attention to the UMTS bands when I read the report, assuming that any modern smartphone would be a quad-band GSM device. Turns out the G2 is only GSM 850/1900, which means this device is truly unusable in Europe and Asia.

Wait a minute, what GSM bands are used in Asia?
The HTC site says otherwise : http://www.htc.com/us/products/t-mobile-g2#tech-specs

According to T-Mobile and HTC sites specs, the phone is GSM quad band (850, 900, 1800, 1900).
The HTC site says "UMTS: Yes"

Europe and Asia are GSM 900/1800, generally. What is interesting is that the HTC page claims the G2 is quadband, but the FCC testing documents don't show any 900/1800 data at all. The phone cannot legally operate in the U.S. in that band unless testing data has been submitted to the FCC. I'm wondering if HTC marketing just c&p from the Desire Z specs and forgot to edit the GSM infos. We'll see soon enough I suppose.

it doesn't make sense why they would release a phone that wasnt quad band. it must be a mistake. it is like power seats on a luxury car. it's just there lol.

So a unlocked G2 could be used on WINDs network here in Canada (because they use the same frequency), can some one confirm this please

Wind uses AWS (UMTS Band IV)... So, yes. But if they do not have HSPA+ enhancements you won't get the famed and promised super speed. The phone should be able to be used on USA (T-Mobile, Cincinnati Bell Wireless), Canada (WIND Mobile, Mobilicity, Videotron)

Based on the G1 test reports...
... the bands listed in the FCC test reports are not at all definitive.
I pulled the FCC exhibits for the G1 and they listed:
GSM 850
GSM 1900
WCDMA Band IV
(plus 802.11 etc)
In other words, no Band I.
However, I've been successfully using my G1 on 3G in both Europe and Asia for over a year now, so it actually has Band I.
I suspect the FCC tests only cover the frequencies that the device is going to be used on *in the US*. Frequencies the device may or may not be capable of using outside the US just aren't relevant.
That being said, the more significant detail is that the T-mobile site lists the G2 as only having Band IV, even though it lists the Vibrant as having Bands I and IV. Looking at other phones, it seems that T-mobile isn't terribly consistent in how they list their frequencies, but that's a (relatively) slim thread to hang onto.

It is quad-band -- for GSM -- as all (most?) modern non-CDMA phones (and some of those) are. But the OP question is about 3G.

I wouldn't put it past T-mo to have just messed up the detail.
I suppose the easiest way to determine would be for someone with an unlocked G2 (or even a locked unit) to take it to Europe or Asia and see if the system status shows UMTS signal or not.

Unlocked G2 Australian user
Hey Guys,
I actually received my G2 a few days ago. Yesterday i purchased an unlock code and entered this in to the phone which it advised was accepted.
The device then rebooted, however once the system loaded i noticed my signal bar had an "x" through it.
Browsed to Network Operators and tried selecting to search for networks and also to select automatically. Both of these selections returned an error "error searching for network" or every second try it would say "unable to connect to network".
I tried a factory reset of my phone but still the same issue.
I tried dialing *#*#4636#*#* which opens a testing screen. I noticed on this screen i can see i have a signal of -85 dBm which is similar to on my galaxy s.
Tried playing with the settings on this screen, i had the option to select network band to which i alternated between all options including auto and AUS, AUS2.
I can confirm this is a Vodafone simcard and it works perfectly in other phones.
I tried a Telstra, 3 and a friends Vodafone simacard all of which produced the same error.
I noticed there are several Australian sites selling unlocked Tmobile G2's.
At this point i would like to try flashing the stock rom on again however i am not sure on the button combo to access the recovery screen.
Last thing to note is yes i have spoke with Vodafone, HTC AU and HTC US, none of the techs were able to help me. =(

Would a G2 work on Softbank (Japanese Carrier) They use the 2100 band IV I believe. I know my T-Mobile Nexus One worked fine on there 3G.
I could care less if the HSPA+ worked just 3G would be fine.

Band IV is commonly referred to as AWS 1700. From the gsmworld entry, it looks like Softbank is running on Band I ("UMTS 2100"). The G1 and Nexus One both had UMTS 900 & UMTS 2100 (the global bands) in addition to T-Mo specific AWS 1700. We're trying to determine if the G2 also has 900&2100 radios, but right now it's not looking very good.

What does "Global Ready" mean for the Verizon Note 3?

I am a little confused about some information I found on Verizon's Note 3 Page. It says that the Note 3 will be a CDMA phone but then lists the following bands:
CDMA Data – 1x and EVDO Rev0/RevA
LTE: B13 (700MHz)
Global Ready (GSM/EDGE: 850/900/1800/1900; HSPA/UMTS: 850/900/1900/2100 MHz)
(original link: http://www.verizonwireless.com/b2c/...t&action=viewPhoneDetail&selectedPhoneId=7194)
Does it mean that if sim-unlocked, it can be used internationally, and how, if it doesn't take a sim card? If it can be used internationally, I would much rather buy a Verizon (for the US) instead of AT&T. I use AT&T only because it's a GSM carrier.

I don't have the answer but I can recommend you to contact Samsung wireless. They certainly have much more credibility.
Good luck

All Verizon 4G LTE devices take SIM cards. They have to, since LTE is based on GSM. Also, historically, Verizon doesn't carrier-lock the LTE/HSPA/GSM part of their 4G LTE phones, so SIM cards from other carriers will work in a Verizon LTE phone out of the box.

I found the answer here, by the Answerer #2. The 4G/Data part of a global ready phone is GSM compatible, and only that part can be locked for data internationally; the calling part will still depend on CDMA in other countries. If that information is accurate, I will stick to an AT&T Note 3.

Truth be told. LTE has more in command with CDMA in terms of radio/air interfaces. It covered within 3GPP standards (GSM then EDGE, the UMTS, HSDPA, etc). Rather than 3GPP2 for CDMA1x and EVDO. That's why Alcatel Lucent had a leg up on LTE since its deployment is more akin (specterally) to CDMA. But they dropped the ball, and except for the US and Some Asian markets, the rest of the world has 3GPP based networks deployed.
the Simple version, is LTE is not directly compatible with any 2G/3G technology, but since its covered in 3GPP, the standards evolved quicker to ensure GSM/EDGE/HSDPA interworking.
And beyond that.. what most people dont know, that interworking doesnt really work that widespread yet. In the US most mobile handsets operate on dual frequencies (especially all VzW models, ATT models are catching up) so they effectively talk CDMA1x and LTE at the same time. iPhones do not support that capability, but GSM has work arounds to allow talk+data.
i'll go back to me hole now
(btw.. anyone with iOS7 and ATT.. what out you've got problems you dont know about when going back forth from 3G to 4G.. I know since at work we talked about how to fix it..

I believe a rumor was that it has the same LTE baseband chip as the iphone 5s so that you could potentially use the Verizon version on AT&T and T-mobile...any truth to that?

Global-ready is basically verizon's way of saying that it has a GSM 3G radio as well as a CDMA radio. That allows the phone to operate in Europe where there is no CDMA service. You can purchase international service from Verizon, or purchase a SIM from a European carrier while overseas. All verizon 4G phones have a GSM 4G radio anyway, because LTE is GSM.
(This means that with an LTE carrier in Europe, any 4G Verizon phone can get data in Europe even if they can't place voice calls (VoIP still possible)).

If I am not wrong with what I am saying, Verizon LTE phones only support LTE BAND: 13, which means that IF you are willing to use 4G with different carrier, they have to support LTE band 13. I have tried to use my Verizon Galaxy Note 2 in South Korea, I was only able to use 3G network via WCDMA, I wasn't able to get LTE service at all. Correct me if I am wrong.

the different N3 variants due in fact support different LTE bands, so you are correct. Minor point not worth nitpicking from earlier post, GSM is not LTE. they both evolved from the same 3GPP standards body, but portions spread spectrum nature of LTE is more similar to CDMA than GSM.

I went to Korea last October, and they wouldn't allow prepaid 4g LTE. They would only allow 3G for prepaid service.
I had a note 2 rooted and custom rom when I went. I'm a US citizen and you have to wait about 2-3 days before you are allowed to sign up for any plan on what they told me.

Unlock S8 from Xfinity Mobile and Used in AT&T GSM network

Say I got a Samsung S8 from Xfinity Mobile(Verizon Network), get unlock code from XM, can I use this phone in Cricket (AT&T GSM network). Samsung support said it is ok, but from some threads it mentioned XM Samsung phone, even after unlock, some band will be locked, may not be used on other carrier. Any one tried before?

I don't see any reason why it wouldn't work just fine. The only thing I can see would be certain carrier features not working. But otherwise should be fine

Verizon and anything related to it uses CDMA technology. Whereas Cricket uses GSM.
GSM phones can be unlocked and switch carriers, whereas CDMA carriers use network-based white lists to verify their subscribers. That means you can only switch CDMA phones with your carrier’s permission.
A list of CDMA and GSM devices can be found here
Mod Edit
However, your phone might be compatible with a GSM network as cricket.
You need to check your phone's version and bands on GSMarena https://www.gsmarena.com/samsung_galaxy_s8-8161.php
And also you need to check Cricket's bands on frequency check https://www.frequencycheck.com/carriers/cricket-wireless-united-states
However, if your phone is already unlocked, you can simply insert a Cricket sim card and try to place a call and use the data to see if it works.

Thanks, understood difference between GSM & CDMA, I read other place saying all the Samsung S8 sold in US are same hardware with different firware, as long as I got unlock code from Xfinity Mobile, then I can flash phone to the new carrier specific firmware(AT&T or Cricket - which is using ATT network), can anyone confirm?

You are correct.

Don't think Xfinity SGS8 will work with GSM.
I believe it will only work with other carriers on CDMA like Sprint.

I can't guarantee it as in the past phones have been difficult to switch between Sprint and Verizon. Verizon's will work on all but Sprint based. And vice versa. But by in all theory yes all the us based models have exact hardware. And should be able to be flashed to each carrier with the csc change thread. The if anything a byop. But the best bet would be to take it once unlocked to which ever carrier and have them Install one of there active Sims and see off it works for sure.
Again shouldn't be any issues other than a few change

what's are CSs that need to be changed?

Depends on sub-model you get. If your phone is the N950U it has the following 2G bands: GSM 850 / 900 / 1800 / 1900 & 3G bands: HSDPA 850 / 900 / 1700(AWS) / 1900 / 2100 & CDMA2000 1xEV-DO. So theoretically a Galaxy Note 8 model N950U WILL work on ALL networks provided that your phone is unlocked from the carrier branded N950U. Check this webpage for the N950U specs: gsmarena.com/samsung_galaxy_note8-8505.php#n950u
If you look at the model of the phone on the back cover it will say N950U on it. N950F does not do CDMA (Verizon & Sprint), The N950FD is the same as the N950F but the "D" means dual nano sim capable (one for each girl/guy).
