Hello!
I am having the following problem:
I bought a t mobile g2 unlocked and I am using it here in Brazil, but my carrier supports only 850 mhz.
My doubt is: is there any way to change that?
Can I make this happen?
I ask because I saw that it is possible in other phones since it "has the frequency" but it in not enable.
Thanks
Rafael

if your phone dosent support the frequency there is no way to change that. look for the tech specs of the desire z.
The G2 is only compatible with the GSM/EDGE frequency of 850 MHz. The UMTS/3G frequency compatibility on the G2 is only 1700/2100 MHz. Its not compatible with UMTS/3G 850 MHz.
You bought the wrong phone for use on your country's 3G network. This is set in hardware, and cannot be changed. This is why you need to fully understand what you are buying, before buying an unlocked device.
Yeah... Thats a shame...
I will se what I can do.
Thanks

Exactly. He'll only get an EDGE connection.

You can't do anything except return/sell the G2 and buy a DZ with the proper frequencies for 3G (that would more than likely be the 850/1900 models).

It's always been my understanding that it's in the chip. But can someone confirm this for me? I'm using WCDMA 1900MHz atm and the operator sucks. There's another that offers 3G but it's on 850 which my desire doesn't support (only EDGE.) I'm quite frustrated.

It's hardware I'm afraid.
The 900 mhz model is the A8181 and the 850 mhz model is the A8183.
Belated thanks for clarification.

How do you know it's hardware? Is there some place you can check which frequency it's operating on?

check the specs for the different models.
it is DEFINATELY hardware.
think about it - if it was software, why wouldn't HTC just produce one model?
very few carriers run 850mhz 3g, so think of the A8183 as a 'special' build.

Well, actually, if YOU think about it: if they make one model, would they be able to charge an additional premium for it?
Hey guys, I looked on wikipedia at the G2 specs, and it lists
Connectivity: Quad band GSM 850/900/1800/1900 MHz and GPRS/EDGE as well as UMTS 1700 2100 MHz, and HSPA+

I am interested in buying a T-Mobile branded G2 (unlocked of course) from the US, and need to know if it will work in the UK or not. From the specs listed there it will, but wikipedia isn't always accurate of course.
Can anyone please confirm wikipedia is right?

Ah thanks, I didn't see that one when I tried to search.
Hey all. I am looking to purchase a galaxy s 3. Would a t mobile galaxy work over seas or do I need an international one? Thanks.
Yes, it will work. The T-Mobile S III has quad-band GSM/EDGE/HSPA+ support.
So in that case id be better off buying one out of contract and using one of the Korean providers when I go over seas? Do you know if the international one would work?

Either version will work. Both are quad-band GSM/EDGE/HSPA+. The difference is that the T-Mobile version supports 1700 MHz HSPA+, while the international version ditches that, and supports 900 MHz HSPA+ instead.

What exactly does 1700 MHz HSPA+ and 900 MHz HSPA mean??? Everything ive found says GSM phones dont work but those were outdated by a few years. Did GSM phones just start working there recently?

You mean it's penta-band has the extra aws band and it should work in korea if they use the same bands like europe

It's not penta-band. It doesn't have 900 MHz HSPA+ support.

Those are just bands that the phones support. And GSM is a world standard, it should work in Korea, and HSPA+ should work too as it supports the 2100 MHz band.
Wifi calling is an option too.
I recently purchased a galaxy note 2 in Korea and I would like to bring it back and use it in the states with AT&T. I read that 4g would not be compatible with the phone but 3g will work? I plan to use this phone for business and I realized the 1 is not designated as voicemail due to it being a Korean phone. Is there way to add this feature on? Are there any other features that I will not be able to use with AT&T? I realize I won't be able to watch tv on my phone anymore.

I don't want to root it and I prefer to keep it stock. I just need to know if the phone will work with At&t's 3g network. It would also be nice if i could fine a way to check my voicemail.

Frequencies used on the AT&T Network (USA)
Frequency Protocol Class
850 MHz GSM/GPRS/EDGE 2G
1900 MHz GSM/GPRS/EDGE 2G
850 MHz UMTS/HSPA 3G
1900 MHz UMTS/HSPA 3G
700 MHz LTE 4G
1700/2100 MHz(AWS) LTE 4G
T-Mobile (USA)
850 MHz/1900 MHz GSM/GPRS/EDGE/UMTS/HSPA
1900 MHz GSM/GPRS/EDGE 2G (EDGE)
1700 MHz UMTS/HSPA/HSPA+ 3G/4G
1900 MHz UMTS/HSPA/HSPA+ 3G/4G
1700 MHz LTE 4G
If that's the international version Note II check and see what frequency's it supports,and compare to AT&T or T-Mobile's. International devices are not carrier locked
If it's a branded phone meaning you got it from your cellar carrier, It could be locked to that provider only.
If your using the unlocked phone, look up the specs on your device and see what it supports, if it matches up to the above frequencies you should be good

Ok so I got these specs for my svh-250k and looks like 3g will be compatible but it also picks up umts 2100 and att LTE frequency uses 2100 for 4g. Am I wrong? Do I need to look at the secondary cellular network?
SVH-250K
Cellular;Networks: GSM850, GSM900, GSM1800, GSM1900, UMTS1900 (B2), UMTS2100 (B1)

Should I sell my korean note 2 and purchase one in the states? I really would hate to get rid of my brand new amberbrown 32 gig phone and downgrade to a boring white or pebble blue 16gig phone. Decisions decisions.....
I'm in the same situation did you already go back to the states and try it out?

This thread is nearly 5 months old, and the OP only posted 4 times in this thread....total...
You will likely not get an answer from the OP...
Do a general search for info on the Korean note threads...as we have 4 or 5 that may help you in getting your answer....
Good luck to you....g

Just reading the specs I would go with T-Mobile, Faster HSPA speeds if you decide to keep your amber brown. Only downside is T mobile's coverage isnt as good as AT&T but if you re in a major city it shouldnt be a problem.
Good luck!
Hi All,
I bought an Oppo Find 7 x9077 which doesn't support the 1700 MHz band that is used by T-Mobile/ATT and most other major carriers in the US in order to get LTE.
My question is, is there a way to unlock the 1700 MHz band using software or firmware flash or is the limitation on the hardware side?
Thanks,
Colin
The 1700Mhz band is not supported by hardware on the X9077.
I see, thank you for the reply!
