I'm so sorry this has to be my first post..

Hey XDA - I've been a browser forever, but I just signed up;
because I am in diiiiiiiiire need of some help.
I'm really sorry this has to be my first thread.
I promise I'm not a troll, and I promise I'll contribute as
much as I possibly can!
I have a situation I am in -
I currently have a Nexus One, on T-Mobile U.S.
It's completely stock, no hacks or roots, mods or anything.
To make a long story short - I'll be switching phones and providers soon (Evo), but I would like to give this phone to my girlfriend, who happens to live in the United Kingdom. She's on the O2 network, and has all the data/plan stuff covered already, I just need to get the phone working for her when she pops in her SIM card.
From what I've gathered, it seems like the Nexus One WILL work on O2 with both 2G and 3G speeds, if this is true; can someone verify?
"O2 use 2100MHz for 3G and 900/1800MHz for GSM (2G - Voice/GPRS).
The Nexus One supports these frequencies for both services."
Also, I've never unlocked, or rooted a phone before. This phone would NEED to be unlocked for her to be able to use it, right? Is it possible to unlock a phone without rooting it? I really am new to all of this. She's not a power user, so I'd like her to keep the stock build and get all the updates. Is that possible? To unlock the phone and keep everything stocked?
Can someone maybe help with that? Or should I just follow one of those guides to "unlock and flash the rom" guides that I've found all over the internet? I really want to just keep everything stock for her, with the exception of the phone being unlocked.
Whatever happens, will the Android market still be working for her?
Does anyone know how Google Maps would work on the phone for her, in the UK?
I'm basically in love with the girl, and we're trying to do everything we can to make the best of a long distance relationship. The main reason I want her to have an android phone (mine) is for her to be able to use Fring with me, and Google Chat - so I'd really hope those apps worked in the UK.
Any help on unlocking this bad boy is much appreciated.
Thank you XDA,
You guys are awesome - and I have all the respect in the world for you.

Hey Dude,
my US Nexus is working fine on O2 here in germany and there are no problems with 3G and 2G, so no worries. And afaik no Nexus One is sim-locked.
Hope this helps.

That actually does help a lot - but,
did you purchase the unlocked Nexus from Google?
I can't confirm, but I've heard that both are different,
the T-Mobile version being sim locked.
I also have the APN settings from O2 U.K already
- I'm aware of that part.

Hi, I am on o2 in the uk and the nexus works Just fine (2g & 3g). Also, I thought the nexus wasn't sim locked, I certainly never had to unlock mine.

Was yours purchased unlocked though?
Thank you

Europe uses the same bands in every country. Its a direction from the European Union so every phone bought in Europe will work in every country in Europe.
Coincidentally, T-MO US uses the same bands so you won't have any trouble with it. I have the T-MO US version here in Romania and works fine on 2G and 3G.
I don't think its sim locked. You should put an att sim in it, although you're only gonna get 2G. But that will show you if its sim locked or not.

I am pretty sure that although Google were selling the Nexus with a T-Mobile option there are no sim- or netlocked Nexus Ones - simply for the fact that Google did not want that. That is also how Vodafone handles the Nexus distribution here in germany: There is an option for a bundle with a contract and the Nexus you get with it is not sim- or netlocked.
Also, to answer another question of you: Yes, your gf will be able to use all functions (market, maps, etc.) without any rooting-action necessary.

That was a genius suggestion.
Popped in a co-workers ATT sim, and it worked
just fine with absolutely zero issues. Thank you!
AHHH I am so relieved. DDDDDDDDDDDDDD!
Siggi : Thank you also for that bit of information, you guys really just took a huge weight off my chest.

1. It will be fully functional on the provider you specified.
2. There is no such thing as SIM-locked Nexus.
3. It's fun using Fring video to show people places.

just for our your clarification: EVERY NEXUS ONE SOLD IS UNLOCKED, and, IT WILL WORK IN THE UK.
Settled.

Exactly.
I also got a Nexus One from Google US and it's working without any problems in germany.

Just remember, even though your Nexus One is unlocked, if you are on contract with T-Mobile and you cancel early, you will have to pay an ETF.

Anyone want to buy me an HD7

I want an HD7 and wondered if any XDA-member could purchase one from o2 and i would pay them through PayPal and they could ship me the phone. I am in the US and on AT&T

Why don't you just go down to Walmart? They have them there already. Besides you'r on ATT and will get no 3g I thought with one from O2? I believe you need one from Telstra (Australian) network and your 3g will work.

I see the rebel sim cards are being developed for wp7 so perhaps 3g is still in the game if i get a tmobile version. I s being on edge versus 3g really that big of a difference anyway?

oh yeah, it's like swimming in tar lol (edge).

Isn't the phone Quad Band? Surely the device will work on all of the GSM networks?
I hope it's that or it's going to be quite a mission finding the right device to work on the right networks int the right countries.

in the u.s., the only 2 big gsm carriers (at$t, t-mo) operate on different bands. the rest of the world is ok lol, the telstra(sp) operates on at$t w/ 3g, any one else on t-mo gets edge.

Ah, ok
So would the T-Mobile HD7 work on standard GSM bands (900MHz and 1800MHz for South Africa)?

Traveling to USA from Europe..

Hi.
This summer I will be traveling in USA(New York and Florida). I have the LG Optimus 2X which according to the specs supports: "GSM (850/900/1800/1900), UMTS (900/2100), HSDPA 7.2/HSUPA 5.76".
1) Will I be able to use my Optimus 2x? I know that the US Nexus S works in Denmark because of the 2100 band..
2) If I can, what kind of pre-paid cards with data can I get? I saw T-Mobile has a Prepaid monthly plan called "Unlimited Talk & Text with 2 GB data" for 70$.
I have been searching but have not been able to get a clear answer. Hope you guys can help me out!
Last year I gave up trying to find any pre paid card with data on, for my HTC Desire. It really sucks to have a phone designed for having internet, when there is none!

GSM won't be a prob, all listed frequencies are used over here i guess the most hassle will be able to find a decent priced 3G prepaid sim; i do wish you luck with your journey; the phone can handle it!
p.s. any change if you can post your prepaid madness with us? Data roaming is a real ***** over here ....

It sure can. I dont mind paying the 70$ for the 2GB T-mobile prepaid that I found, but I cant help but wonder if there are any hidden extra charges(signup or whatever) and if It is possible to return the card if it does not work on 3G.

I had the same one when I was in L.A. But I only got Edge cause the phone I used did not support de band.

T-mobile use 700/2100 band for 3g/4g so it will not work with 3g just edge

I got my O2X from Singapore and it support 900/1900/2100Mhz UMTS and i am using it on AT&T's 3G without a problem.
Check the box of your phone, it should state the accurate frequencies as most online stores advertise the wrong frequencies.
My phone retail box states the 1900hz band and it is indeed working fine on AT&T's 3G.

i9300 3g question

Hello,
I have just purchased an unlocked international version of the Galaxy s3 from newegg.ca
I'm not allowed to post the link to the product as I am a new member.
Before I bought it I noticed that it will work on Rogers (in Canada, where I am from) so I went ahead and ordered it. I went back to the site a few days later and noticed that in the details it says that this phone will only work on the AT&T 3g network. In Canada we don't use AT&T so basically I am stuck with a smart phone that I can't connect to a data network with. A useless phone. I can send it back and get a refund so it's really not a big problem. I am wondering however, if there is a way that I can get the phone to work on a rogers network? Is there anything I can do, or do I just have to send it back? Thanks.

So i am unsure about your carrier networks over there, but usually when a phone is locked to a carrier here in Australia, you really just need to pay an unlocking fee to use the other networks. Sure there might be some difference between their networks, but overall you should be able to get a working phone, maybe just not on the fastest mobile infrastructure.

Hey thanks. It is already unlocked. But for some reason, which I don't understand, the 3g will only work with AT&T networks. I'm sure there is a way to fix it if it's rooted or something like that but I just don't know how.

strange, according to wikipedia both AT&T and Rogers use 850/1900MHz for their 3G, so if you buy a phone for the AT&T network, the 3G should work fine on Rogers..

yeah I wish I could post the link to the product. I even called the company and they said it would be AT&T only. I guess this is why noobs should just stick to carriers and contracts.. I can't sign a contract because I may be headed overseas (hence the international version of the phone) but I am just not knowledgeable enough to navigate this situation without risk, I suppose

[Q] newbie question, AT&T or TMO Moto X outside US

Hey all,
Hope this is in the right place. Saw a few similar questions, but nothing exactly like what I was looking for.
I currently have a VZW Galaxy Nexus, rooted, running Shiny ROM with Xposed and GravityBox. Thinking about dumping VZW and going to a Moto X on AT&T or TMO, both prepaid. Question is, which carrier's phone would I be able to use outside the US? I'll be going to Europe this summer and would like to purchase a local SIM in Europe and use it there, instead of paying roaming fees on AT&T or TMO.
According to Wikipedia (can't post link) and what I've read on here, the TMO version is SIM unlocked. So this means it will work on all GSM carriers, right? In the US, that would be AT&T (if TMO doesn't have good signal where I live), and when I travel, that means I can use a local SIM, correct?
Thanks in advance, any help is appreciated!

Yep, that's correct. T-mo is SIM unlocked. I use mine with AT&T actually too. It should work abroad with no trouble other than tracking down a local nano sim or cutting one down.
If however you want to use LTE abroad I don't think the bands in the T-Mobile version match those used in Europe. HSPA+ should work fine though.
From my experience when traveling abroad a prepaid SIM w/ LTE was way more expensive than something I wanted just for being able to gchat home and look up directions on gmaps so it was a moot point.

Thanks, that's exactly what I was looking for! I figured LTE wouldn't work in Europe, I was fine with settling for HSPA+ or 3G.
Found a thread here explaining the differences between AT&T, TMO, and Dev Edition. From what I can see, the TMO edition is more flexible than the AT&T edition. Only difference compared to Dev Edition is that unlocking the bootloader on TMO voids your warranty.

LTE works in Europe although is not yet as widely spreaded as in the USA. But you'll be fine with 3G which is fast enough and most countries are well covered with that network. More important issue is roaming if you are planning to visit different countries. You must switch between different operators and even using service from the same operator in different states ( e.g. T-mobile) imply roaming charges. In my opinion the best solution is using local sim with best data plan and voip for calling in every country. If you don't want to switch sim cards, you may find the best roaming solution with prepaid Vodafone Italy. You can buy its clone online (http://www.motorhomewifi.com/product/europa-sim-roaming-data-sim-card/) and refill it in any Vodafone shop around Europe.
