[Q] I9500 S4 on American Tmobile Network with missing 1700 Frequency - T-Mobile Samsung Galaxy S 4

I live in America and was thinking about ordering the S4 GT-i9500 for Wolfson Audio chip reason. I wanted to use Tmobile because they have the best prices. I saw that the i9500 network is:
Network: 2.5G (GSM/ GPRS/ EDGE): 850 / 900 / 1800 / 1900 MHz; 3G (HSPA+ 42Mbps): 850 / 900 / 1900 / 2100 MHz
And from https://en.wikipedia.org/wiki/T-Mobile_US#HSPA.2FHSPA.2B_.224G.22_upgrade, I see that HSPA+ uses 1700/2100 Mhz. It also saids:
Band IV AWS consists of the 1700 / 2100 MHz band pair. Data is transmitted upstream on 1700 MHz and downstream on 2100 MHz. A device must support both frequencies to access T-Mobile's AWS data services.
I don't understand, but sellers on ebay are claiming i9500 will work with Tmobile's 4G in America. How would the i9500 work on the American Tmobile network if it doesn't use the 1700 frequency? What would be the draw back?

Tmobile is refarming its 1900Mhz band for hspa+. If you're in an area that has it you could get 4G with that and pretty good speeds. You won't get LTE and if you're in an area without the 1900 you'll get 2g speeds.

Here's a more technical explanation.
T-Mobile used to exclusively use the AWS (1700/2100) spectrum for DC-HSPA+42mbps. They are currently refarming this for LTE use.
HSPA+21mbps is being moved to the 1900mhz spectrum. So, in areas that have been refarmed, you will have HSPA+ access (NOTE, no 42mbps). In areas that are not refarmed, you'll be limited to EDGE service.
I have a Galaxy S2 GT-i9100, so I have the same limitation. I signed up with T-Mobile about 2 months ago and on a weekly basis, I'm seeing towers refarmed. They intend to have it nearly completed by end of 2013, thus limiting the areas you'll be on Edge only. Eventually, their entire 1900mhz network will be HSPA+ 21, with their AWS network being LTE.

If not 42mbps, what speed?

Their HSPA+ network on 1900mhz is limited to 21mbps.
Basically, their network prior to refarming was:
1900mhz (PCS) - EDGE
1700/2100mhz (AWS) - DC-HSPA+ 42mbps
They have since acquired a TON of PCS and AWS spectrum from; failed AT&T merger, Verizon spectrum swap, and MetroPCS merger.
This will allow them to expand to new markets currently not served, as well as expand bandwidth in existing markets. So, their current plans are to refarm the network to;
1900mhz (PCS) - HSPA+ 21mbps
1700/2100mhz (AWS) - LTE
There will be some limited spectrum for the old EDGE (PCS) and DC-HSPA+ 42 (AWS) available for legacy devices, but that will eventually (at least 2020, most likely) go away. The goal is to have LTE over their core network by mid-2014, and HSPA+ 21mbps being the expanded fallback network. T-Mobile will also be taking part in the 600mhz auction in mid-2014. Their network plans will be made more clear (VoLTE, LTE-A) after that auction. Lower frequencies allow for better building penetration. T-Mobile is currently silently lobbying the FCC (through other groups) to remove Verizon and AT&T from that spectrum auction for the sake of competition.

so eventually you'll be able to access the 21mb range? Thus, if in a refarmed area, you could get 21mb with a i9500?

For explanatory purposes: Ever noticed how, if connected to a 100mbps LAN, you don't ever see 100mbps? That's link speed, not real world.
Applied here, HSPA+ has a top link speed of 21mbps (assuming both ends are compatible). DC-HSDPA has a top link speed of 42mbps. Real world performance will be 3-8mbps on the former, and 5-15mbps on the latter. I've seen spikes up around 12mbps and 25mbps, but those are incredibly rare. Bottom line is, do not expect LTE speeds. I currently have a phone that has 21mbps HSPA support on PCS (1900mhz), and on T-Mobile, I get 6-7mbps in most HSPA areas.
I hope that helps.

Shouldn't it be more? Are you using the Snapdragon version on the American Tmobile network?

Wow, kind of considering the I9500 again. I live in Austin, Texas. How will I know if Tmobile converted here and if I can get the 6-7mpbs in HSPA where ever I am here? Also, right now I have a Nexus S with 3G. I have to admit that I only am able to get 3G(Tmobile) about 50% of the time and the rest is edge speed. Would HSPA consistency be this bad?

If you got the Nexus S model sold for T-Mobile, that has AWS support. That means that switching to a PCS 3G phone like the i9500 means that AT BEST you will have the same Edge/3G coverage ratio you have now, and at worse you'll have mostly Edge coverage. Your 3G data speeds will be faster in the areas you get it though. It will be a tradeoff.
EDIT: Here's a user-generated map of areas that have had 3G and HSPA+ refarmed to PCS. Looks like a few rowers directly in Austin have been refarmed. This is a massive project by T-Mobile and is nowhere near being complete. However, an areas HAS to be refarmed in order for them to launch LTE, so refarmed markets (that already offered 3G/4G AWS service) are the ones that are getting LTE eventually.

Can I use unlocked ATT S3 on tmobile $30 monthly 4g?

I am reading it might work on edge only is that true?
Different Bands... no 4g, just E... Maybe someone know more than me but IMO you cant use 4g
You can use the phone but you will be restricted to Edge data speeds. ATT and Tmo use different freq bands for 3G/HSPA.
ATT uses 850/1900
Tmo uses 1700/2100
You may be able to get 3G/HSPA speeds once Tmo refarms its 2G bands as 3G, but who know when that will be.
You will only get EDGE in MOST areas, T-Mobile is "re-farming" the 1900mhz spectrum from 2g to 3g/HSPA. They are doing this in order to be able to use the iPhone on their network, but it would have the same effect for any unlocked phone. They say they'll have their entire network re-farmed by the end of next year. I haven't found an official map, but this has places where it has been sighted: http://www.airportal.de/

Looks like there are many spots in Bay Area, CA.
I tried this on my att S3 and got the sim card and was on the phone with tmobile tech for hours...it never worked and he was trying to tell me it was my phone....not...my phone works great with straight talk.
It definitely works on the AT&T phones. I unlocked mine and bought a tmobile prepaid sim the other day. Able to get 3g in San Jose but still only Edge where I live. Will be switching and dropping at&T once the refarm hits my area.

AT&T version HSPA+ 21 or HSPA+ 42?

I'm confused on which version of HSPA+ the AT&T version will have. The T-Mobile version has 42mbps plus LTE support. Many have reported the two versions are identical. I always thought AT&T's 3G network maxed out at 21mbps? So if it does have HSPA+ 42 support does that mean we'll get faster 3G speeds, despite the fact that the network tops out at 21mbps?
at&t version maxes out at 21Mbps HSPA+
T-Mobile's has DC-HSPA 42Mbps

Thanks. That's what I thought.
I hope someone finds a way to unlock the LTE on the Tmobile version. That would be SUPER. You'll get great DC-HSPA speeds (which also saves battery life) and ludicrous LTE speeds (which has limited coverage)

In my area it's maxed out at 1Mbps...go figure
same hardware?
I'm trying to separate the hardware from the carrier's network. Are the two phones hardware identical, but the AT&T can't use the dual-cell speed because their network doesn't support HSPA+ 42 (which uses two simultaneous 21mbps streams)? Can the T-mobile version do LTE 100 except that T-mobile just doesn't have that technology in their cell towers?
The reason I ask is because I wonder if I buy one phone can I use it on the other network? If it is all just which firmware I use, then it wouldn't matter.
It might also be relevant because if I was roaming in Europe I would want the more capable phone, assuming one is better.
But if both actually have the same hardware, then it wouldn't matter.
Yeah all hardware is the same. AT&T's network only supports HSPA+ 21.

[Q] Should I get ATT or TMobile GS3

So I am looking to switch to T-Mobile from sprint and want to get the S3. I understand the T-Mobile GS3 works on HSPA+ and operates on the 1700 Band. I also see that the T-Mobile version does not have LTE. Now the ATT version operates on the 1900 Band and will only work on slower speeds until T-Mobile activates the 1900 Band here. Spoke to several reps and they state sometime this month. Will the ATT GS3 have the LTE that will work on T-Mobile when they activate it? So would it be better for me to get an ATT GS3 so that I have LTE when it becomes available? Thanks in advanced

I have Tmobile and it works ok, It depends on the service coverage cause where I live I don't get 4G on any carrier lol.
That's a tough question to answer. Is it a matter of want or need LTE on your mobile device?
Arguably, at&t has better service than t mobile. But since t mobile is still at the stage of refarming their antennas/towers, Tmo could be just the same as their counterpart after its done. I have t mobile and coverage has been excellent. Data speeds are speedy but not quite as fast as at&t's LTE.
On HSPA+, i get great to decent speeds that can get all of my mobile needs online. It would be a plus to have LTE but i don't need it.
Do you get what i trying to get at?
Sorry i had to write this quickly.

I say go for the Tmobile S3. T-mobile's LTE rollout won't be for a long while, and even when it does become available we don't know if it uses the same LTE band as ATT. My guess is that it won't. Tmobile's HSPA+ is plenty fast where I live for all my needs. You will only get EDGE (2G) speeds with TMobile on the ATT version of the S3 until Tmobile refarms their network. But even if they do refarm where you live by the end of the month, the many other places will still only be covered with the 1700 spectrum.
S3 on Edge is a pointless phone. Even with the 1900 mhz bands rolling out, your data will be spotty at BEST. Even in NYC Manhattan, the 1900 mhz bands are probably 20% complete. Go with the TMO version and you won't regret it.
I get up to 25mbps I average about 7-12 who cares about LTE? Go with T-Mo its cheaper and you will get faster speeds. At my home I get faster data speeds than my baby mama on ATT with her HoX soon to be OG Note
sent from my Samsung Gangster S III on the T-Mobile network
I also have the same dilemma.
If T-Mobile will use LTE on the same frequency as ATT currently does, won't using the ATT SGS3 future proof it for LTE on T-Mobile network?
Am I missing something or do these devices have same specs (except T-Mo having 1700) once 3G moves to 1900 on T-Mo?
OP, I suggest you test T-Mo's network for coverage and speed in your area. I will be doing the same.
Get the T-Mobile version if you value fast data speed.
Don't buy a phone and hoping that it will have the correct technology to work on a network that has not even start to build yet.

[PSA] You may be able to use HSPA+ on T-Mobile

Sorry if this is old news, I searched the forums and couldn't find a thread where this was explained.
Until recently, it wasn't possible to use HSPA+ with the Glide on T-Mobile, because T-Mo used to use different frequencies (1700/2100) than AT&T (850/1900) for it's HSPA+ service.
However, T-Mobile is migrating its HSPA+ network over to the 1900mhz band. So apparently that means that IF you are in an area where T-Mobile has already made the switch (and your phone is not carrier locked to AT&T), then you can use HSPA+ on T-Mobile.
One thing to note is- since the phone is only operating at 1900mhz and not 850mhz, the speed is cut in half (at least that is how I understand it).
So instead of getting 42Mbps you'll only be able to get 21Mbps (max). Still, it's way better than 2g. Source

Sorry, am I missing something? The Captivate Glide specs show it as having UMTS 850/1900/2100, so shouldn't it work both with 1900 and 2100?

The way I understand it, the older T-Mo towers use both 1700mhz and 2100mhz for their HSPA+, using 1710-1755mhz for uploads and 2110-2155 for downloads. The radio's in the Glide are missing the 1700mhz band so it won't work in the areas where they haven't rolled out the switch to 1900 yet.
I am only going by what I have read on the net, so this may not be completely accurate.

[Q] Verizon- High Frequency LTE- Weak in Buildings?

I am thinking about switching from Tmobile to Verizon in the USA and getting a Note 4.
I can't stand how Tmobile operates on a high frequency- My signal is always inconsistent and unless I am standing outside away from a wall or roof, it will be at 1 bar.
I read where Verizon is rolling out thier 4G LTE on high-frequency AWS airwaves with 1700 MHz/2100. Since these are high frequencies, does this mean I would get the same signal drop from buildings and walls?
indoors you will mostly be on band 13. that band could be congested in the area.
most phones capable of band 4 do seem to jump to band 4 pretty quickly when it's available
Indoor lte penetration has not been working as expected
What us band 13 comparable to in terms of bar strength and speed?
After doing some research Tmobile is using 1700/2100 frequencies also. Since I get bad reception with Tmobile currently, does this mean I will get bad reception with Verizon?

Verizon main LTE network uses band 13
and is about 750 download and 780 upload. This works well indoors.
Verizon XLTE is Band 4 and is only in some markets and I think uses 1700/2100 which completely blows indoors.
