Att vs tmobile vs international unlocked - Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help &

Which would be better on straight talk in a att area a tmobile phone unlocked, an international version or what? Within a straight talk att area using att sim? Where you have lte actually in the radio? In the i9305. Another words which version allows you to unlock and get hsdpa+ quad band including lte .. 800, 850, 1900, 2100, 1700, 2600 ect I am interested so if i go into an att, tmobile, verizon sprint ect area i can get max out if it lte, hsdpa+, 4g, 3g, ect

[Q] att note i717> lte on tmobile??

I am looking into this question of the att note getting lte speeds on t-mobile once their lte is launched on the 1700 aws band -- after t-mobile refarms their 3g/4g to the 1900 band they won from att in the buy out fiasco.
The att i717 note uses the 700/1700 bands for lte on att service.
The tmobile note uses the 1700 band for wcdma (hspa 42?) - not lte on tmo's service.
When all is said and done, will the att note running on tmobile's network get the lte speeds on the reconfigured 1700 band?? :fingers-crossed:
Sounds logical, but my logic does not match my technical knowledge, which is not so great.:silly:

HTC One have T-Mobile hspa+?

Does the HTC One have hspa+ on T-Mobile? It doesn't have the 1700 band. I live in an area that doesn't have LTE but has hspa+ and hasn't refarmed the 1900 band so I would be stuck on 2g in this case?
Yes, you would be stuck with edge (2g) until the reframed network is live. Purchase the device from T-Mobile, it will have the 1700 band

Yes, that's what I was asking. So the T-Mobile version of HTC One has the 1700 band and will work with hspa+? I can't find the specs for the t-mo version anywhere. I guess we'll know for sure when it actually comes out.

of course the tmobile version will have the 1700 band. why wouldnt they? they dont want people be on 2g speeds now...
You probably looked at the dev edition (which is a att version).
Problem with TMobile phone is the 32gb ;/
I would love to get my hands on 64gb HTC One but it doesn't have the hspa+ aka 1700 band
Now I have been told you might be able to flash a radio but it has yet to be confirmed whether this is really possible or not.
Sadly I will be force to buy a S4 because of this issue. Unless someone can confirm hspa+ radio can be flashed on Dev Edition

I really hope someone creates a mod to Enable the Tmobile AWS band on the Unlocked HTC One, similiar to what they did for the ATT Galaxy Note 2. These high end phones have the hardware to work on the the various gsm frequencies, but they come disabled. Someone was able to figure it out on the galaxy note 2, but I have been searching and I don't see anyone working on a similiar solution for the HTC One. I guess time will tell. I've ordered an unlocked HTC One, and will test to see if I get 4g LTE in Chicago which is listed as a 1900 refarmed area. The consensus seems to be that if i'm in an area that does not have 4g lte i'll be reduced to 2g Edge speeds. This my friends...would suck donkey balls.

Same here. I ordered the unlocked ONE. I live in Houston which is refarmed 1900 also with lte. Had I known my dam phone would be delayed again I would have just waited for the tmobile version.

Your last statement about 4G LTE and 2G Edge speeds isn't necessarily true. I live in LA and we don't have LTE for T-mobile yet, however T-mobile has refarmed many of their towers around here to use the 1900MHz band so that you can get HSPA+ on phones that don't have 1700MHz support (like many AT&T phones and unlocked phones, like the HTC One Developer Edition). I received my HTC One Developer Edition today and drove around a bit here. While my phone doesn't have 1700MHz support, the screen still showed "H" for HSPA+ everywhere I went, and I tested speeds as high as around 9000kbps download. So being able to get 1900MHz HSPA+ is not tied directly to if an area has LTE or not.

[Q] Official Unlocked or Unlocked T-Mobile

I'm considering whether to buy an T-Mobile version and unlock it or a "Officially Unlocked" version on HTC's official website. I have found two differences so far.
(1) The first is that T-Mobile version seems to support more 3G networks while Unlocked supports more 4G networks.
Here is something from HTC official website.
Unlocked version
HSPA/WCDMA: 850/1900/2100 MHz
4G LTE: 700/850/AWS/1900 MHz (US)
T-Mobile version
3G - UMTS/ HSPA: 850/ AWS/1900/2100 MHz with HSDPA up to 42 Mbps
4G - LTE: 700 MHz and AWS band
AT&T version
3G - UMTS/ HSPA: 850/1900/2100 MHz with HSDPA up to 21 Mbps
4G - LTE: 700 MHz and AWS band
So does it mean that both Unlocked and TM versions can completely support AT&T network, TM version can completely support TM network (of course), and Unlocked version partly supports TM network (no 3G AWS support). Am I right?
(2) The second is about S-OFF. Neither Revolutionary nor Moonshine mentions the Unlocked version, but they both support TM version.
PS: Can I use more frequency bands by flashing something into an S-OFF HTC One?
If you're going to use it on T-Mobile, why not just buy the T-Mobile version? The unlocked version doesn't have support for AWS bands.

I'm not quite sure which operator will I use.
if your in the USA the tmobile version will probably serve you the best since it can pick up pretty much every companies 3g and 4g signal without problems. tmobile or ATT.
there is currently no way to flash a radio to support other bands not sure if this is even possible currently

I am on a TMobile branded phone, which I unlocked to use with my AT&T account, on which I previously had an iPhone 4S. I've been having some issues getting on LTE so far. I did talk to AT&T several times to make sure that the One was provisioned on my account, and the account was changed to a "4G LTE" data account. I've driven all over the downtown Los Angeles area (downtown, Chinatown, Dodger Stadium, Commerce, and Hollywood) and have yet to see LTE when I'm on AT&T. I get it fine on Tmobile (I picked up a pre-paid Tmob SIM.) I've tried several different APNs (wap.cingular, phone, and pta (which doesn't even connect)). As of right now, I'm a bit stumped as to where the issue might be (it presents itself in Sense, Android Revolution, and Google Edition ROMs). I may just buy an HTC One from AT&T and will put my SIM card in it to see if I get LTE on there, and then return it.
My belief, and what just about everyone has said, is that the TMob phone should be able to get on AT&T's LTE. For whatever reason, and I can't quite lay blame anywhere yet (I'm new to Android, so it could very well be I'm not getting something), it's not working.

[Q] UMTS/HSPA 900 + LTE Band 20 Flash ATT S5

I was hoping the ATT S5 would get UMTS 900 and LTE Band 20 (Europe Digital Dividend 800 Mhz), I was disappointed to see that it does not.
I live 45 min. North, Northwest of Philly and AT&T is the best carrier in PA - HANDS DOWN! I also travel every week, all over the US for work - and I'm very happy with AT&T in general. One thing I noticed on my S4 is that I could not get LTE in Burlington, VT on it - but I had full bars of LTE on my iPad Air. Side question; What band does ATT use for LTE there that the S4 don't support?
Anyways,
on the S4 I was able to activate AWS freq. for UMTS by flashing it. I need to do this for UMTS 900 and/or (pref. AND LTE Band 20, since I travel to Northern Norway all the time - and there is only UMTS 900 and LTE 20 some places there.... If I cannot have the phone flashed to have the current bands AND the wanted bands - would there be a way to flashing it back and forth from ATT to "Euro/International" mode?
M:good:

AT&T uses bands 2, 4, 5, & 17 for LTE. Band 17 (700mhz) is what most of their LTE is on. That's why the signal is always good. I am starting to see Band 2 (1900mhz) in some areas. I saw Band 4 (AWS) in Chicago in a few areas (probably were capacity is weak).
Yes, with the S4 you could unlock the AWS frequencies. I do not know if you could flash UMTS 900 with an S4. You will not be able to flash anything with frequencies on the S5 as AT&T has locked down the phone entirely. It will follow in the Note 3's footsteps.
I think they discourage people unlocking their devices and using them on other networks. AT&T is forgetting what GSM is all about IMO. If AT&T LTE is not that important to you, you may want to consider the international variant which will support your European frequencies. It will NOT work on AT&T LTE though.
Hope I helped.

AT&T is most important, as I am in the US 95% of the time. At least the S5 will have LTE 1800 and 2600. My hometown in Norway should get LTE 1800 later this year. So at least I will have GSM 900, UMTS 2100 and LTE 1800.
Do you, or anyone else know if AT&T will unlock Phones on the Next plan? I got the S4 full price, but I'm using the Next plan for the S5.

They'll unlock it if its paid off entirely. But that doesn't mean you can't unlock it yourself.

t mobile samsung galaxy s8 + (plus) doesn't run 4g lte from at&t?

Hi every one i got a s8+ from t mobile i switch to at&t and my s8+ is not running the 4g lte of at&t i verified the APN and nothing i called at&t and they say the phone is not compatible with their 4g lte. What can i do?
To my knowledge, and others may chime in differently, the LTE bands are not compatible between ATT and T-Mobile. It would work in reverse, that is taking an ATT phone to T-Mobile, but not the other way around.

This info is from T-Mobile's website: https://support.t-mobile.com/docs/DOC-34266
Network
4G LTE: 2, 4, 12, 66
3G / 4G (HSPA / UMTS / HSPA+): Band I (2100), Band II (1900), Band IV (1700/2100), Band V (850)
2G (GSM, GPRS, and EDGE): 850, 900, 1800, 1900
The hardware is EXACTLY the same. There is absolutely no difference between a T-Mobile S8 and an ATT S8. The only difference is the firmware. And you can install the ATT firmware on your S8, or even better install the Unlocked XAA firmware.
