Hi I am looking into getting a Hero. I was wondering what version of the Hero would work with the US 3G network on TMobile or AT&T. I have both services but would prefer to use this on TMobile. And how hard is it to get the phone working on the US carriers?
No 3G on both networks; EDGE only. Take a SIM, put it into the phone, voila.
Edit: I apologize for my bluntness. It's just this question has been asked ten thousand times too many :[
Not quite correct!
The Telus Hero (available in Canada) uses the correct bands for AT&T. You are still SOL on T-Mobile US though!
Regards,
Dave
As I’m sure most of us already know Bell and Telus (formerly CDMA-only carriers in Canada) have launched a new HSPA network. Both the iPhone 3G and the iPhone 3GS now work on the new network.
I understand that HSPA is a GSM based technology. Bell is now issuing SIM cards with new activations. I was wondering if anyone would know if the HTC StarTrek (specifically the Cingular 3125) can be made to work with this network. I am willing to do firmware updates obviously.
Best regards,
The Fish
If you mean 3G/3.5G then yes and then again no. If its like the networks in the UK then the StarTrek will work on the GSM portion of the Bell network, but as I dont think it has a 3G chipset it will not be able to access 3G/3.5G services.
I may of course be wrong but that is my understanding of the situation.
I have a question... when I go overseas w\ my old Infuse, I always had to flash a non-AT&T radio to truly "unlock" the device. The radio ATT had on the firmware made it so you can ONLY roam on the partners AT&T wanted you to be able to, even if you had a SIM from say Thailand.
For example, if I go to Thailand, there are about 5 GSM carriers. AT&T partners with 1 of them. If I put in a SIM from the UK who partners with 4 of them, the ONLY carrier the radio will let me latch onto is the ONE overlapping carrier that AT&T also partners with. Flashing a non-ATT radio resolves the issue, but it's quite frustrating to have had to deal with on the ATT Infuse, so I always used the Rogers radio, which didn't have the limitation.
I assume that's going to be the case with the AT&T SGSII that I just bought as well. Does anyone have any radio suggestions? And since we don't yet have ROM Manager, am I going to have to flash with my PC or what?
Thanks as always!

Interesting - I've never seen any indication that Rogers radios in the Infuse had this positive effect. Especially since the Indian users on the Infuse forums had no problems with any Indian carrier that had frequency bands the Infuse supported. Of course, maybe that's because they always used a local-carrier SIM, and not something a little wacky like a UK sim in Thailand with a US phone...
I9100 radios will not work on the I777.

HEHE, yeah. AT&T has several roaming partners in India, so odds are they'd be able to use it just fine with any SIM even if a non-Indian SIM.
UK sims are not as uncommon as you think. MOST global travel sims are registered in the UK or Eastern Europe. Mine is a Tru SIM. Tru is from the UK (you may have heard of their VOIP service, TruPhone). The SIM has a US number, it's just UK-based, since their carriers are far ahead of the US in terms of EU roaming, so it gives the most beneficial rates of any SIM.
It's really the most noticeable in countries where AT&T only has 1 or 2 roaming partners, but the country has 4-5 GSM carriers. Most southeast asian countries like Philippines, Thailand, Malaysia, Singapore fall into this category, so it can be a bit annoying be limited by my phone. Even in Japan last month I had issues because the roaming carrier Tru will allow (almost any) didn't jive with what AT&T's radio wanted to attach to (it had weak signal). Flashing the rogers radio solved, but hopefully there will be radio updates out for GSII.
EDIT: it's likely that it's not less of a restriction, but just a better roaming relationship with more countries. Canadian Carriers are a bit more "traveled" and progressive than Ma Bell. AT&T loves to advertise that you can use your phone in many countries, but they don't say that in many countries the one and only provider they roam on has TERRIBLE coverage or only a tiny part of the country covered and just gives them a good deal to boost their roaming count.
BTW, good to see you again Entropy! I missed you the couple weeks I had Infuse while you were away, hehe. Glad to be back w\ a phone you have so I can enjoy the great things you put out!
I could be wrong, but i thought it was the SIM card that told the phone what towers were roaming and not roaming. The only way an AT&T phone would keep you from going on another providers towers in another country is if you were still using your AT&T SIM card, or if your phone simply didn't work on the band of the carrier you were trying to use.

Well a SIM is just like an ID, and the carriers will either let you register with that ID, or not let you register. However, AT&T in all of their glory modified the radio so when you go to a country, the radio will disallow access to a carrier. I am not quite sure how they do it. For example, if you go to Thailand w\ an ATT sim card you'll likely roam on DTAC or AIS. You can't roam on Tru w\ an AT&T sim card because they don't have a roaming agreement, but the phone fully works fine if you put a Tru sim into it. Where the radio also limits you somehow, is if you have a SIM from say O2 in the UK, and you pop it into an unlocked Infuse 4G, you can't roam onto Tru, even though Tru is a roaming partner of O2, and the phone fully supports the frequencies and everything works just fine.
Weird right? Now flash the Rogers radio. Since Rogers has Tru as a roaming partner, it works if you put in a Rogers SIM, Tru SIM, O2, etc.... that's where the mystery and misery lie. I'm really hoping they didn't do the same to the SGSII's radio.
My girlfriend wants to include me on her new Sprint account. Sprint doesn't have an equal to my Amaze. Is this possible? Will everything be functional (except T-Mo's add-ons, of course)? Please shed some light. Thanks!
How do you plan to connect a GSM phone to Sprint's CDMA network?
no not possible, 2 different technologies. Sprint uses cdma and tmobile uses gsm.

The Amaze is GSM meaning it REQUIRES a sim card as do all T-Mobile and AT&T phones in the US. Sprint is on a CDMA network which works with the antenna inside the device, an internal "sim"card if you will. There is NO WAY to use a GSM device on a CDMA network. There are ways to flash Verizon, Metro, Alltel and other CDMA device to Sprint's network but not any GSM phones. Take a look into flashing the HTC rezound from Verizon to Sprint's network. That device has essentially the same specs but is CDMA. Hope this helps.
Why not ad her to yours? it will be way cheaper than Sprint.
Id be glad to do it for ya
Any who currently have this phone with Tmobile USA can confirm to me if it gonna working on their network. As far I knew this phone, it definitely not support the 3G/4G bands from TMO USA, but what if roaming and spectrum agreement with AT&T go through FCC, will I be able to use call with TMO and use 3G service of AT&T if possible?
