Is the Qualcomm chip on the new TMo SGS2 worth it than the Exynos siblings?

Just as the question say:
TMo SGS2 Qualcomm vs. SGS2 siblings (AT&T/Sprint) Exynos... Is it worth it?
Found this on the other forum that I found interesting, and could be a debatable topic:
The AWS (1700) bands are supported only by a handful of carriers. It doesn't exist at all in Europe and Asia. There's little reason for manufacturers to include it on their global phones as so few people use it. It's the reason the T-Mobile SGS2 has a Qualcomm chip instead of Exynos like the rest of them. After the merger, it won't even exist in the U.S. any longer as AT&T plans on using it (1700) for LTE. If you want versatility and the ability to use unlocked phones, change to AT&T.
^Even international version doesn't support T-Mobile 3g/4g (HSPA+) network.. Not many phones support their network. Or maybe it will.. but not everywhere

Tmobile compatible phone question

So I am keeping my Nexus 4, however I am in the market for a a phone for my wife. It has to work with T-Mobile and I would love to find her a HSPA+ compatible phone, however i am really confused on how to figure this out.
For example I am looking at this phone at GSMArena:
Sony Xperia T and they say these are the bandz:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1700 / 1900 / 2100
How do I know it will work with T-Mobile's HSPA+?
Any help will be appreciated.

Thanks bud, but that doesnt answer my question, I dont need to know what coverage is in my area, but more what phone is capable of using T-Mobile's HSPA+

Yes it will. T-Mobile used 1700 and 2100 for HSDPA.

Thanks EL Daddy! So if a phone lists those bands 1700/2100 that means it'll work with HSPA?
I ask because I am also looking at this phone the Xperia S and those bands are :
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1900 / 2100 - LT26i

That one will probably not work as I believe you need both the 1700 & 2100 to work ( up & downlink connection).

3G or UMTS is as follows;
2100 refers to Band I / IMT and is used in Europe and Asia
1900 refers to Band II / PCS and is used by AT&T in cities, and by T-Mobile (1900 migration).
1700 refers to Band IV / AWS and is used by T-Mobile (most HSPA service is still here).
850 refers to Band V / CLR and is used by AT&T in rural areas.
http://en.wikipedia.org/wiki/UMTS_frequency_bands
T-Mobile is slowly moving HSPA from 1700 to 1900 to support unlocked iPhones and free up 1700 for LTE deployment.
I would look for a phone that supports both (1700 now, 1900 future) or it may have a short life span.

Awesome! I see now, so in order for the phone to work on HSPA it needs both 1700/2100 bandz. AAHHHHHH SWEET! Thanks guys I made sure to hit the thanks button on both of you!

Nexus 4 works great on T-mobiles HSPA+ . I regularly get 20.8 mbps down/2.5 mbps up.. and this is in a 1700/2100 mhz AWS area .. PDX area has not been refarmed to 1900mhz yet - and Nexus 4 supports both 1900 mhz HSPA+ and AWS HSPA+ - so no worries.

Just to clear up one thing. T-Mobile often refers to 2100 as the Download Frequency of AWS (Band IV), while most hardware manufactures reference 2100 as IMT (Band I). See column 2 in the wikipedia link I posted earlier.
I get both bands here in NYC (mostly AWS) and the speed is about the same on both (20 Mbps / 2.5 Mbps), but ping results are quite a bit lower on PCS.

LG-D803 Frequencies

I got an LG-D803 for my girlfriend but won't work on the Canada's WindMobile network which uses AWS 1700.
I saw on this website that apparently the LG-D803 doesn't have this frequency.
The site lists the D803 as:
2G Network Quad Band GSM 850/900/1900/2100
3G Network HSDPA 850 / 900 / 1900 / 2100
LTE Network 700MHz / 850MHz / 1900MHz / 2600MHz
Is it possible to get the phone to work or am I just out of luck?
Thanks!

Bump... Anybody?
If there's no options to enable AWS then I guess I'm going to have to sell this phone. :crying:

[Q] SM-gt900h T-Mobile???

I am about to purchase a Samsung Galaxy S5 GSM unlocked from HSN (the reason from hsn is because i can pay for the phone overtime instead of paying right up front). I am currently on Tmobile with my lg that uses hspa+ 42 and i wanted to know if i would get tmobile "4g" 42 megabit speeds on the S5 considering the fact its international with an octa-core processor?? Or would I be stuck with edge/2g??

Bands:
T-Mobile version: HSDPA 850 / 1700 / 1900 / 2100 - SM-G900T
G900H HSDPA 850 / 900 / 1900 / 2100
The only difference is the 1700 band that is missing from the H variant.
This thread might help, I think that by having the 1900 band you'll be OK for HDSPA if you are in an area that has refarmed towers, but better read it all the way through (I didn't)

You won't have LTE of course.

[Q] Unlocked AT&T s 4/s 4 mini in South Korea

Can anyone confirm if unlocked AT&T models of the Galaxy S 4 and S 4 mini would be compatible with networks in South Korea? Thanks in advance.

You'll have to compare which radio frequencies the phone is compatible with and what the carrier uses. I know the first can be found on Wikipedia, and possibly the carrier frequencies also.

I did that, and then I ran into this chart and kinda freaked out. Do only the frequency bands matter?
The ATT S 4 seems to definitely have 850 MHz for LTE which SK has in Korea. I couldn't find as reliable information for the S 4 Mini though. Wikipedia also lists SK as having a UMTS/HSPA network at 2100 MHz and according to GSM Arena, the S 4 supports HSDPA on 2100 MHz. So does that mean it's compatible?

Wikipedia has the international S4 Mini listed with the same frequency bands, and if the I337 has them then I can only assume the Mini would. So as far as I know it should be compatible. However, if you're talking about SK Telecom, their wikipedia page also says things about CDMA, and I don't know if that'll work at all.

:/ I was hoping for SK since that had the most matches with bands. Also, I don't think that's necessarily true because when I was looking at S4 specs on either Phone Arena or GSM Arena, they had listed some bands that the AT&T model didn't have that the others did. I assume the same would be the case for the S4 Mini but I don't recall seeing AT&T specific specs regarding the bands for it.

and here: http://en.wikipedia.org/wiki/SK_Telecom#Services
GSM Arena has this:
HSDPA 850 / 900 / 1900 / 2100
HSDPA 850 / 1900 / 2100 - SGH-i337
No 900 on AT&T.
and
LTE 800 / 850 / 900 / 1800 / 2100 / 2600
(Bands 1, 3, 5, 7, 8, 20)
LTE 700 / 850 / 1700 / 1900 / 2100 / 2600
(Bands 1, 2, 4, 5, 7, 17) - SGH-i337
No 800, 900, and 1800 on AT&T.
Wikipedia lists SK Telecom as having UMTS/HSPA on 2100 and LTE on 850. Wouldn't that work with the i337?

I suppose it should then, I've just known CDMA and GSM phones not to cross. My friend tried a Verizon SIM in my S4 and it seemed not to work, but I'm not knowledgeable about the differences of GSM and CDMA and whether or not all service will work correctly.
