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.

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

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.

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)
He guys
Here is the question straight forward, I bought a used US Cellular HTC Touch Pro 2 from someone who uses the phone on a CDMA network while i will have to use it on a GSM network the seller said that there is a SIM slot underneath the battery which he never used, Will this phone work on my GSM network outside U.S. and will that phone be unlockable?
thanks in advace
HTC website
HTC website doesn't say anything about GSM support for this phone "US Celleular Touch Pro 2"
any ideas guys???
The touch pro 2 is a world phone and yes it has a sim slot (at least the sprint/verizon models do). I unlocked my phone in the U.S. and used it on AT&T with my buddies sim card, the only problem was that the radio is does not have the 3G frequencies for the U.S. you might have to research if this holds true out side the U.S. since every other country uses a different frequency set for 3G access.
Also plz tone down the font size
ya the seller satated that the phone has a SIM slot then i should assume that it can be used hopefully, and the 3G is frequinces is supported by this phone over here in Egypt and i should be fine.
sorry about the font

i cannot seem to find a straight answer to whether ALL nexus s' ship carrier unlocked. i live in philippines and the phone is being offered through globe although i plan to use the phone under the smart network. i was under the impression that google shipped all of these unlocked but i'm hearing from few people that it is PROBABLY locked to globe. i also see unlocking services that offer unlock codes for this particular phone on their websites implying that some of them do come carrier locked. can anyone confirm if these are all unlocked or not? thanks
the nexus s is not "carrier unlocked". it never was advertised as. even though 2g(edge) will probably work on any carrier, 3G(or 4G) is carrier spscific. thats why there are different versions of the nexus s. it will work on other networks as long as the 3G bands are the same. the nexus s is bootloader unlocked(well, you can unlock/lock it yourself).
isnt 3g/4g only carrier specific because of the carrier 3g frequency bands? i'm purchasing the phone here in the philippines which uses 900/2100mhz to connect to 3g as it is the standard operating 3g band for all europe and asia. my main concern is whether i will need an unlock code for the phone to even work with a sim card from a different carrier than the one i originally bought it for. 2g will work on every carrier and 3g will work only if that device supports your carriers 3g frequency band but before connecting to either one, the phone has to be unlocked and pass the "sim check"

None of them have any carrier lock. However you'll likely want the correct phone for your 3g frequencies. You could use the wrong one, you just won't get HSPA

dude! lucky you i found this thread
I bought mine through Globe. I tested officemate#1's Sun sim and had officemate#2 send a text message to that sim while in my Nexus S, and I received it. I also sent a text message back to officemate#2 still using the Sun sim. and she got it back. So I guess we can say it's unlocked
Im not sure if I got lucky getting an unlocked Nexus S (even though there's a small sticker inside the Nexus S that says "this mobile may only be used with a Globe Sim card").
but i've read a lot of forum (since im researching about this because i have plans of using this in Singapore and i hate going through the hassle of unrooting and unlocking) and a lot of them say Nexus S units are unlocked even when a telecom carries it.

Google won't allow any provider to touch the software on the nexus line. So no matter what stickers it has or what the sales rep tells you, the phone is sim unlocked.

Will I be able to use the phone in India.

Is it True?
Does your carrier in India use the same frequencies as the Korean model you bought? Did you at least look that up first?
Sent from my Nexus S 4G
I am not sure about the frequency used in India and Korea.
Before purchasing the product in Korea, I had checked if the phone would be working with the SIM card that I use in India. It was working.
The Nexus S variant that released in India says that it supports the following
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 900 / 1700 / 2100
I am trying to explore more about the frequency related things that you mentioned.
I was told that they all come carrier unlocked.

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!
Got my FIDO Razr HD. Rogers SIM = all is good. AT&T sim = asks for unlock code, which i buy online.
After entering code, phone appears to do a factory reset. During the reboot, a box pops up:
"SIM not allowed MM #3"
Now the phone permits "Emergency Calls Only" with the AT&T sim. Rogers SIM = still good.
When I put AT&T sim into my other phone (HTC desire) it works fine on roaming (rogers network). So I know sim + signal is fine.
Don't understand this error message.
Did I mess up the unlock?

Thanks for the replies everyone. to answer the questions:

2) they were regular sims that were cut down.
3) haven't had a chance to visit USA since posting topic- but when i do, i will test both cards and also visit an AT&T shop to bug them about it.
Is sim corrupted? I don't think so because it works fine in HTC desire. But I guess trying a new one will prove or disprove.
imei is recorded via att and you can t use att on your razr ;( this is a strange things... but is real ... many user report this ! ( not just with the razr ) this is not a phone problem

How do we know this is happening, has someone from AT&T discussed this before?

Thanks for the replies everyone. to answer the questions:
1) i don't have any other sims right now: just rogers + ATT. Next time i am w/ friends I will ask to borrow telus/bell microsim.
2) they were regular sims that were cut down.

I want to let you know that I was able to use a Bell sim card in my phone. That's what I used to unlock it with.

I am using this phone with at&t with no problems, I took my sim out from my iphone 5 and used a adapter to go to micro sim and it works fine, no issues.
I'm receiving a Fido RAZR HD to be used with AT&T this afternoon, I'll let you guys know if there are any issues.
OOI, is AT&T seen as a much better GSM network than T-Mobile in the US?
I was looking at the T-Mo USA site, and there are some amazing "Monthly4G" SIM only plans (e.g. $30/month for 100 minutes, unlimited texts and 5GB of HSPA data).
This seems much better value than AT&T, Verizon and even Sprint! But is their network sketchy compared to the others?

AT&T offers the second largest network coverage behind Verizon. They are also one of the two GSM carriers in the United States, and tend to be more popular with mobile phone enthusiasts because their UMTS bands are more common and used with other regions such as Canada or Australia. T-Mobile does indeed offer excellent value, but they use mainly AWS band in addition to PCS band in selected regions, thus making them the lesser choice for using unlocked phones from outside the country.
Hey,
Just looking on wiki:
http://en.wikipedia.org/wiki/T-Mobile_USA#Radio_frequency_spectrum_chart
http://en.wikipedia.org/wiki/AT&T_Mobility#Radio_Frequency_Summary
It looks like T-Mo mainly use 1900 for 2G and 1700 for 3G, whereas AT&T use 850 and 1900 for both 2G/3G, right?
So if I bought a Canadian Razr HD XT925 and came to the US, would I be able to use T-Mo's 3G network? I am guessing no, since it does not support 3G on 1700MHz.
But then there is a note on that Wiki page saying that they now have a roaming agreement with AT&T after the failed acquisition. So if I forced the phone into "WCDMA only" mode from the test menu, would it then fall back onto the AT&T 3G network?
Sorry for taking the thread slightly off topic
Cheers,
Su

As you have read, T-Mobile did acquire PCS bands from the failed merger with AT&T, but these bands are not as utilized as their 850 MHz band so it's not as widely available as you may think. Some areas might be able to use the 1900 MHz band for T-Mobile 3G, but I would check with fellow T-Mobile users to confirm first before you dive in headfirst. I know that there are T-Mobile users in the Dallas-Fort Worth area that are getting 3G data connectivity with their unlocked AT&T iPhones.
Well T-Mo do daily plays for like 2 bucks right, so I can always try this out before committing to a contract
Do you think AT&T would be the better bet if I am bringing my own device from Europe?
The reason I ask is that I may be coming to a US college for a couple of years, so naturally, I'm planning ahead to see if my phone will work over there

If you're using a device from Europe or Asia, then yes, you have a much higher chance of being able to get 3G connectivity with AT&T. Off the top of my head, Nokia seems to be the only one that tries to actively keep AWS band in their radios.
Hmm, so I did a bit of research on GSM Arena. Seems the Nexus line of devices consistently support 1700MHz 3G (including the Nexus S which I currently have).
Guess who cancelled their Nexus 4 order last week, and opted for a Canadian RAZR HD instead...
Whoops
