Sim Unlock HTC Dream - G1 Android Development

Can remove simlock from HTC Dream and from any other HTC device.
This service is not free.
You will get unlock code in 5 minutes to 72 hours.
It will costs 50$ = 34EUR = 27GBP by donation to xda-developers.com - http://forum.xda-developers.com/donations.php
Please send me a Private Message for details.
P.S. you do not need to reflash, disassembly, hard reset your device!

How is this better then just asking T-Mobile for the unlock code?

I believe they will only unlock it after 6 months of service

90 days... But with the ETF, it's not like you're going to buy from T-Mobile then cancel and use it elsewhere after unlocking it through this guy. It's much easier to buy it off of a current T-Mobile subscriber if you plan on using it with another network.

you can just buy it from somewhere else. e.g. eBay and you might want to use it on other carriers. or you might just want to have an unlocked phone in case you travel and put different sim card on it.

Right, I understand the reason for having an unlocked phone... I don't think I'd pay that much for an unlock, but whatevs.

It seems like the XDA Dev team will probably have a way to unlock it in a couple weeks anyway especially if the OS is open.

You have to remember, it's only on T-Mobile in the US for now... I don't know if I should expect the developers of SIM unlocks (olipro/cmonex have done most of the work in that department) to get their hands on one... Maybe they'll grab one just for development, but for all we know their only plans could be to stay with the Touch Diamond/Pro/HD.

I dunno. We still don't really know how "open" the Android OS is yet. Although the kernel is open and freely available, it handles low-level hardware functions. SIM functions seem to be handled higher up in the Android stack and not all the Android source code has been released yet. Unless I'm missing something, it's a wait-and-see situation as far as SIM unlocking goes.
Even if I were to want an unlocked G1 (which I don't) I'd be wary of shelling out $50 for an unlocker to a phone that hasn't been released yet. And honestly, tmo's unlocking policy is very liberal as it is.

i am not a t-mobile customer, but the rest of my family is. i buy t-mobile phones all the time and i get the unlock code no problems. i'm not sure on if they are gonna give the unlock code right away, but if not i can always get the unlock code through my family. i hope we get a free unlocker before i get around to getting the phone

i work for t-mobile UK and on a contract you only have to have the phone for a month then you can buy an unlock code for £15
so you save yourself alot of money doing it via T-mobile UK plus they now issue most unlock codes on the spot unlike their old 28days in the post way

T-Mobile USA's policy is one, free unlock code every 90 days.
And I don't understand why you'd care about SIM-unlocking it, as the US version is really only good on T-Mobile's 3G network. T-Mobile uses different 3G frequencies than AT&T and the rest of the world. As I understood it, the European version will have a different radio set inside. I'd like to hope I'm wrong, but I understood that to be the case.

You're confusing GSM frequencies with 3G frequencies. No phone maker yet has made a phone containing all the GSM frequencies, all the 3G frequencies, *and* the new tmo USA 3G frequencies. You can use the phone anywhere, but the 3G data would be crippled on anything but tmo-USA...and even tmo has said that the phone would pretty much suck without 3G.

ok you may be right about the frequencies
but the spec dose say that
HSDPA/WCDMA:
Europe: 2100 MHz
so it may not work with at&t 3g
but it might work in EU on 3g

Again, that's not what I'm hearing. The G1 in the US is configured for download on tmo's 1700MHz spectrum and upload only on 2100MHz. If I recall correctly, Europe does it all on 2100. That's the part I hope I'm wrong on, but just having "2100" on it doesn't mean it's configured for the particular part of the band that the Europhones use.

90 days of continued satisfactory service will do.

what you all forget is that he is doing it non profit.
all the time he has been doing these unlocks, its probably helped a lot to the upkeep of the site.

Euro/Asia 3G (WCDMA Band I) uses 1900 for UL and 2100 for DL while T-Mobile AWS (WCDMA Band IV) uses 1700 for UL and 2100 for DL. However, WCDMA Band I was called UMTS 2100 therefore the confusion.
BTW the T-Mobile G1 is a dual-band HSDPA phone (T-Mobile AWS and UMTS 2100)

OK - So does this work on Next G

Alright, I know this has probably been covered some where, and I know that this is a "world wide site", and I know this is all going to sound stupid given the answer is in my own post, but a question:
I am really liking the look of this phone, and I want to get one (when ever it comes out), but in Australia, our largest HSDPA network is Telstra NextG, which is 850 band. Looking at the specifications for the machine (this site had everything well laid out):
http://www.gsmarena.com/htc_touch_pro-2413.php
It states the European/Asian version will be HSDPA 900/2100. So I am going to guess that I can not use it on the Next G network with this version of the phone. Correct?
Also, the site states that the Americas (US) version is 850/1900.
So, I assume I have to get a phone from the US to use it on Telstra's Next G. Is this correct, or is there some other quirk that I do not know (like some CDMA difference or something)?
Thank you for homouring me
Correct, the NextG network will not work on this phone at present. Also correct, it will work on the US version. Here's the nice part though...
One of our members was nice enough to leak a version of the new AT&T ROM for the upcoming Raphael in the US, and since the hardware is all the same, HOPEFULLY flashing with that ROM will enable the 850mhz HSDPA band you and I both need. I'll be testing this on a Raphael when it releases in Europe, and I'll have a post up very quickly in this section letting people know how it went. If it works, you can buy any version and flash it (only takes 5 mins) for it to work in AUS.
Edit: Don't listen to GSMArena, HTC lists this phone as quad-band although they say it's tri-band.
Cheers and Beers

The above sounds good. I really do not want to go down the road of a Telstra locked phone (not that Telstra will release this one). I await your tests with anticipation.
Cheers and beers
Yeah, well, I figure if it doesn't work (hoping it doesn't brick it) I'll just resell it for like $25 less and it's not much of a loss for trying.
I don't know much about Australian telephone networks, but I've always wanted to go there and see what it feels like to be upside down all the time.

Haha, seems like one of the nicest vacation spots in the world. Can't wait to go there someday.
Here is a photo of the Australian system:
http://www.flickr.com/photos/jeffwerner/278050267/
The Australian networks arent too bad. We have a choice of frequencies here. Telstra have the 850mhz 3G band and Optus and Vodafone are each expanding their exisiting 2100 3G network using 900mhz which will be launched over the next few months. The good thing about Raphael is that it will work on the 2100 and 900 3G bands and given that Telstra's voice and data plans are ridiculous many of those who want to use data on it wont care about the absence of 850...this is good news. However if the device can be flashed to work for everyone...even better.
As for the photo of the Australian networks that was a network similar to what I built in Sydney in the early 80's. A large carrier paid me a small fortune to decommision it as it was making them look bad!!
I'm also in Australia and plan to get this phone from one of the UK stores as I can't wait for 3 odd months for it to be released here. Now I'm sure there might be a few aussies here who have ordered from online stores outside Aus. What I wanna know is if I might have to pay any import duty on my purchase? If I buy from expansys uk, the unit will cost me roughly AU$920, but with bank fees and shipping charges, I would have paid $1010. I know that import duties are applicable if the cost of the unit is $1000. So does this count for me as well?
I just want to avoid paying more that I should.
However, I need Next G
Thanks all for your input on this. I was pretty sure that the phone would not work on the NExt G nextwork if I bought one (from say an internet dealer in Sydney or Melbourne), but as you can see from my "location", I need Next G. There is not 3G nextwork in the Top End except Telstra Next G (Or at least none that cover all of Darwin and its area adequately. Anyway I don't knock Telstra too much).
Further to that, I work away a lot and once again, Next G is OK (note I only said OK) for outside of major cities, and Telstra GSM is good for most rural townships also.
Anyway, I suppose my upgrade will be to a TyTN II to replace my old phone, at least it has the 850 band that I need for Next G.

The Diamonds were listed as Tri-Band too, but now every Diamond is quad-band since they came out with the newer ROM. Same with the Touch Pro, some ROMs (apparently that nation's) don't support quad-band, but in time (or with a quick reflash) they will.

Thnx finally some clarification...
But still strange that our countries HTC would not enable that bandwith. They state it's a business phone. But business often means travelling arround the globe. Quadband would then be preffered above tri-band....
But black you know for sure the bandwith can be activated by just software? Some people say you need a different antenna. (I'm a noob in that area...).
Thnx anyway!

The GSM antennas are all in every Diamond, the problem is with the UMTS radio. To keep the Diamonds so small, HTC had to remove the American UMTS radio, making it so you can't use a European Diamond to get 3G in the US ever. Likewise, the American Diamond will only have the US bands of 3G (850 and 1900). As for the GSM bands, though, EVERY Diamond has the capability to be quad-band, so you'll at least get EDGE wherever you go. Hope this clears things up.

Just wondering if anyone had n update as to the effect of the new radio rom in the touch pro. I understand the US issue was different with a release of GSM only touch pros (Booo Hissss) but would realy like to confirm if we are able to reflash to expand on the UMTS frequencies here in Aus making the touch pro UMTS tri or quad band.
Thanks for all the info in this post too.
I'm wondering if someone has worked out how to get the extra band to work in Australia as well. I am on Next G and my brand new phone simply sucks right now and I'm hoping I don't have to go over to a different carrier when my contract is up. I kinda like Telstra Next G, dare I say it.

As far as I know it works fine with an ATT Fuze with a regular touch pro you'll never get NextG on the 850 band, it's a hardware limitation.

will Verizon or Sprint TP2 work on TMO

Just curious if possible when you unlocked the GSM radio on the Sprint or Verizon TP2. Is it possible to get all features i.e. 3G..etc to work on Tmobile?
sorry if this is a dumb question but considering the price difference between the TMO TP2 and Verizon it would be much cheaper to buy it and just get it unlocked for TMO.
The Verizon version is as easy to unlock as calling Verizon and asking for the unlock code (they'll redirect you to another department that deals with that type of thing).
After that, you should be able to use it on both AT&T and TMobile, or any other GSM provider.. but you won't get 3G speeds, only 2G/EDGE, since the TP2 doesn't include the 2100Mhz band that TMobile and AT&T use for their 3G.

Actually, AT&T uses 850 and 1900 for 3G, T-Mobile uses 1700 and 2100.

Really? My bad, I was taught that they both utilized 2100Mhz.. if you're correct, and I believe you are, then the TP2 (and even the storm, which supports 850/1900Mhz) can utilize 3G on AT&T?
The CDMA Touch Pro2 will get 3G in Europe:
HSPA/WCDMA:
Europe/Asia: 900/2100 MHz
Up to 2 Mbps up-link and 7.2 Mbps down-link speeds
(found it here: http://www.htcwiki.com/page/HTC+Touch+Pro2+(CDMA))
T-Mobile has some weird-ass thing going on with their 3G that you need 1700 and 2100 on your phone, so you can count that out.
Basically, you can unlock it. The only problem you'll have is no 3G. The big question... will you be able to make it roam on Sprint?

It is that easy to get the code....but you need to be a Verizon customer for 60 days or more (probably to stop stuff like this, if I had to guess). I really don't know what they would do if you bought it outright though. If worst comes to worst, you can get it unlocked somewhere for like $10.

[Q] Droid 2 Global 3G Bands outside the US

Hi all. I've just found out about this brilliant phone. Had no idea it existed. I've always liked the Motorola Milestone (qwerty physical keyboards are a must to me) however i ended up getting the wrong version of the milestone (european) with the wrong 3G bands for my carrier so i could only get Edge speeds.
Anyways, it seems like the Droid 2 Global version uses simcards. I live in the Dominican Republic, Claro (my carrier) runs on the 850/1900 bands and it seems like the D2G can work with them, in theory. I've been reading a couple of threads regarding this though, it seems like those bands have been locked out by verizon so people don't use it on other US carriers such as AT&T which happens to run on the same bands i need (850/1900). But others say its the carrier ID that has been locked out. I read something about a user being able to get 3G speeds on Chile, but i've no idea what bands he was using.
What i want to know is, if i ordered a Droid 2 Global phone, would i be getting 3G speeds using my Claro simcard here after having it sim-unlocked?
There's also the Milestone 2 of course, but they seem to cost $500+ plus they dont specify which bands the phone works with. I dont want to end up buying the wrong phone version again. Also, It seemsl ike the droid 2 global is being sold for a less ($300-400).

read the spec
I am using my SIM-unlocked D2G fine here, on a carrier that uses 850MHz UMTS.
The Milestone 2, as far as I know, is still only available in a 900/2100 UMTS variant so far.
From what I gather, the lock Verizon put on the radio to prevent use on US GSM carriers is based on the MCC (mobile country code) number associated with networks based in the USA, and not the frequencies themselves. In effect, once unlocked the phone will work with any GSM provider (on a supported frequency), except those based in the U.S. This would explain why the AT&T 850MHz network (MCC 301) doesn't work, whereas the Telstra 850MHz network I use (MCC 505) does.
One complication about buying a Droid 2 Global now, is that from various reports on this forum, some devices don't respond to their SIM unlock codes (!) and are effectively unlockable. If I were buying a D2G now for use on a GSM carrier, I'd only buy one that has already been unlocked - wouldn't want to take the chance on getting a phone that is unlockable. This might be why some are being listed for dirt cheap!

Wow thats not good is it. Thanks for the advice, i'll make sure the phone is unlocked. I've never really understood how phones are unlocked by third party anyways. But I understand you can have them unlocked by giving verizon a call and under certain conditions, they'll provide the unlock code for free.
I was in the Dominican Republic last week with my D2G and it worked perfectly (unlocked using Rogers Canada service). Claro service sucked a bit (coverage wise) but worked fine (3G), Orange (EDGE) seemed a bit better where I was.
I am pretty sure you will be fine AS LONG AS you get unlockable/unlocked D2G.
ok one last question,
does anyone know if a droid with bad esn will work ok with a different carrier's simcard if unlocked?
I would assume droids with bad esn will be going for cheaper on ebay
bas esn mean d phone could be stolen so it will b a hassle to clear the esn
How can one know if the phone has a bad ESN? Just wondering.

Obtain the esn from whomever you are purchasing from. Then ask Verizon regarding the esn you were provided.
Sent from my DROID2 GLOBAL using Tapatalk
but wouldnt you only need a clear ESN if you're going to use the phone with CDMA? or would that affect GSM usage as well ? (simcards)
According to the eBay listing I bought mine from, it has a bad ESN (at least, it explicitly stated "will not activate on Verizon") - but the GSM/UMTS radio works fine.

Bad ESN will only affect use on Verizon and its MNVOs (possibly). GSM networks will work fine. Just remember though if it's not already unlocked, and the ebay unlocker codes don't work, it will probably be near impossible getting verizon to give you the code for a phone with bad esn.
thanks for the info. I''ll look for unlocked plus bad ESN phones on ebay and see if theyre any cheaper

[Q] Factory unlocks, ebay and international carriers.

Hello gents, I'll start with a short story to get you into the thread:
Me and my girlfriend live in Venezuela, our service providers are not up to par with american or european carriers in terms of available devices, so we bought an HTC Magic for each of us last year to try out Android, everything was fine, I learned how to root it, install roms and such, and we had a pretty good run with the phone and the OS.
Last week we got robbed and they took away our phones, I decided to get a Nexus S for her and I found one at a good price on eBay(270$+shipping) however this one is branded for Sprint, will I be able to go to my service provider and just tell them to attach my account to the phone I bought on ebay? or are the Sprint and Verizon Nexus S locked to those carriers exclusively?
If the answer to the second question is yes, then a third question is raised, can I in any way unlock this phone to use it on my non-american service provider?
I have seen other threads and the replies are always "the Nexus S is factory unlocked." but I dont know if this refers exclusively to the ones sold in the UK or retail stores in the US.
I apologize for any noobish behaviour, I'm a big fan of devices and gadgets yet I lack a lot of the technical skills you all seem to demonstrate.
Thanks in advance.

There is no such thing as a Verizon Nexus S. Sprint Nexus S have different radio bands than the regular Nexus S (I9020T/I9020A/I9023) and features a 4G radio with it. You have to make sure that the phone is compatible with your carrier's bands. Another thing to note is that the Sprint Nexus S is CDMA (No SIM card) as well.
All Nexus S models come unlocked regardless if you're on the contract or not. Sorry to hear about your incident
The model I bought is GT-I9020T, according to people on the internet(random links on google) this model works on GSM frequencies of 850, 900, 1800, & 1900. It supports UMTS 900, 1700, and 2100 frequencies.
My current provider works on 850 and 1900 for GSM and 850 for CDMA.
Do you think I will have trouble using the phone I bought for my girl?
I feel terribly dumb when I ask this, I cant explain why, hehe.
Oh, I think I figured it out, I bought for her the non branded GSM version, so yes, it will probably work on my provider.
But what happens if I buy a Sprint CDMA one for myself? Those are definitely cheaper, and CDMA seems to be better down here, at least more stable.
Thanks for your replies, and simpathy, it's been a rough week without a smartphone for both of us.

I'm not sure and I wouldn't say the CDMA version is more stable. I personally never used the Nexus S 4G but from what I can tell from threads is that there are problems with WiFi or something of that sort.
You might want to ask the carrier yourself via phone to see if it would be compatible or so. Just let them know about the bands the phone supports.
And that's interesting if your carrier supports CDMA and GSM.
CDMA = No SIM card
GSM = SIM card
GSM is more popular around the world. Just including that just incase!
Alright, so I talked to my carrier they said the following:
-If I buy a CDMA phone with no contract on the US I will be able to register it on their network.
-If I buy an unlocked GSM phone I can register it on their network.
I guess I'll have to buy a couple of GSMs just to be sure... even tho they are about 100$ more expensive.
Thanks for all the replies, catch you later!

HTC 7 Pro network options?

I friend offered me the opportunity to buy an HTC Arrive/7 Pro for a very attractive price, without contract, naturally.
Now, I love WP7, and I like my T-Mobile family plan (in the United States). Unfortunately, I'm a totally newbie in the area of using phones on different carriers. From what I understand, I think it's possible to use an HTC Arrive with a T-Mobile sim card, and make calls, but you cannot modify/unlock it to get 3G support, which I do kind of need.
Am I correct? Or am I way off? It'd be great if I could get it working, complete with 3G, with a little work, on the T-Mobile network, but it's just as possible that I couldn't even make basic calls.
3G worked fine (here in Europe) on tested HTC 7 Pro...
if you want use different mobile carriers, your device must be SIM free (SIM unlocked)
So, it would be possible to use my T-Mobile 3G, provided the phone was unlocked?
I've always been a bit fuzzy on the distinction between a normal non-contract phone, and one that is actually unlocked. I do know, of course, that unlocked phones go for a much steeper price then their locked counterparts...I've seen some websites detailing instructions how to do this, allegedly, is this something I could do myself to a non-contract phone (albiet with paying for a code)?
Phone must be unlock (no branding and no simlock). You nothng write about simlock that phone. When device not have simlock you can use everything simcard and everything frequency, but I don't know how work T-Mobile in your country (not from where you wrote) maybe operator locking 3G but i don't think. You must plug in sim card to phone and check that.
Ah, I'm starting to understand, I think. The HTC 7 Pro is, unlike a lot of Sprint's phones, GSM, HSDPA, WiFi, CDMA compatible--T-Mobile's phones are all GSM. I'm in the USA myself.
However, I can't say anything about frequencieis or anything like that. Has anyone ever tried? If not, I may have to just break down and try on the phone first (with an unlocking code).
I'm not sure but I think that HTC 7 Pro and HTC Arrive is the same only difference to Arrive not supported pre-NoDo. You must try plug in sim card and you learn.
On the page HTC specifications wrote that 7 Pro and Arrive frequency is the same:
Network
AT&T:
HSDPA/WCDMA: 850/1900/2100 MHz
GSM: 850/900/1800/1900 MHz
Telus:
HSPA/WCDMA: 850/1900/2100 MHz
GSM: 850/900/1800/1900 MHz

You must try.
Thank you, I think my only option will be to try.
I was able to find some information on T-Mobile's frequencies, but not Sprint's, at the moment.
I'll be able to return the phone, so the cost would be, potentially, the cost for the unlock code (assuming HTC won't give me one for free). I may have to try this out myself.
Sprint is CDMA and the Arrive doesn't have a SIM card (I have the Arrive and know this for a fact). You won't be able to use it on T-Mobile or AT&T.

I was about to say this, but I'll add my hat to the ring and also say there is no SIM card slot on the 7 Pro (Like there was on the TP2).
Though I wish there was. It makes the Photon look really compelling. :/
Really? That's extremely strange, there's a thread on this site showing how to access the SIM card slot and MicroSD slot.

Maybe this is only for HTC 7 Pros outside the US, which are not CMDA?

The guy who made that thread is from Prague, to that's probably the Euro version of the 7 Pro. Europe is mostly GSM. So if you got the unlocked Euro version, it would work on T-Mob, but only EDGE data, not 3G/4G. T-Mobile uses an oddball 3G frequency (UMTS 1700/2100 MHz, also called Band IV), that is not shared by many other networks in the world.
