SGS2 ATT usuable in Germany with o2?

Hey Guys,
I am situated in Germany and in my opinion, the ATT Versions of the S2 is the most beautiful one. My carrier ist o2.
Is it possible to buy a S2 ATT via the US Ebay and use the phone without any restrictions in Germany?
I guess I need to root it first, then unlock it and then I am good to go? Are these thins easily and safely to achieve? Is it that simple? What about the network, is the american version compatible with the german network? Can I use hsdpa?
Any other restrictions?
Thank you in advance.
the usual problems with US phones in europe... no 3g, but if your only there short term, it may be worth picking up, otherwise just get the euro version with the correct bands.
also i havent checked but there may be a quad band umts unlocked
AT&T version only has tri-band (850/1900/2100) HSPA+ radio. So if your carrier O2 uses 900 band for 3G service, your phone will only work in 2G mode.
International version of GS2 has quad-band HSPA+ and it works everywhere.

[Q] Does 3/4g work in Argentina?

Yes, it will work. Argentina uses the same 3G bands as AT&T on the US.

[Q] tmobile in att area, which sgs3 to get?

I've been wanting an upgrade from my G2x for a while and what I want, which is what everyone else wants, is the Samsung Galaxy S3. I don't know which model to get, being that there are so many models of the S3 depending on the service provider. Here's the situation: I'm on a t-mobile value plan, living in West Virginia (I'm a student) with the only service here is roaming on AT&T, thus I only get edge. Can I use a different model, like an unlocked AT&T, and then be able to use more than 2G? Then be able to get full 4G when I do go to t-mobile service area? (From the chart by forum moderator, it shows AT&T shares 1900 mHz, 2100mHz, HSPA+, so it should technically work with tmobile, correct line of thought?)
*I already know that unlocked international version won't be able to get on anything more than 2G in US, it having different radios.
Also, read somewhere that I could buy the AT&T model and be able to use international LTE networks. Is that true? Could someone here enlighten me about the issues with the radios/frequencies (for US) for S3?
Much appreciated. Tried to find this question answered somewhere, and couldn't so posting now.

[Q] Vodafone EU HTC One not working on T-Mobile US network

I have a vodafone EU HTC ONE phone.
I have now moved to the US and am on T-Mobile.
However I can't get 4G/LTE on the phone no matter what I try (I've manually entered the fast apn)
Does anyone know if this is even possible?
Do I need to unlock the Bootloader, etc flash with the T-Mobile ROM, etc. ? Will this even work?
I do not think the Vodafone One has the T-Mobile LTE band built in. According to Wikipedia, TMo US uses the 1700MHz band for LTE. Your phone doesn't have a 1700MHz radio.

LTE problem

Hi need help please , I have a Galaxy S4 I545 , I can anly connect on 3G and even in the back of the device says s4 verizon 4g lte . When I change the LTE network goes without service. Let alone globally connect on 3G, I wonder if I can enable or install 4G LTE bands . Thank you
The SCH-I545 should have 4G enabled automatically. 4G is already installed on the phone unless it has been messed with (ROM,kernel etc.). Is it possible you are just not in a 4G area or have it on your Sim?
Are you located in the States?
The phone is 4G capable, only in USA. Outside, its only 3G. That is how Verizon did it, locking bands so Verizon users cannot have LTE with other providers like T-Mobile or Sprint or ATT. T-Mobile should work worldwide. For Verizon, you will need to unlock bands.
What country are you in ? Most probably, you need band 3 or band 28 which are deactivated.
I'm from Morocco
