Has anybody been able to use the Xperia Ion LT28H or LT28I on Tmobile's 3G/4G? Some spec sheets list the AWS band and some don't.

The LT28H might be alright, but the LT28i will not be, due to that it only has one bandwidth it can use and not the other one. It is the missing the 850Mhz band,
LT28i barely works on T-mobile. I tried that and it dropped out of network very often.
I have an LT28i and it worked fine on T-Mobile's 3G when I was over there for a month. Their coverage is patchy in some places, but I got good speeds when I actually had 3G coverage...
xperia ion lt28i
i ran into this dilemma before and started a thread as specs conflicts
after some research and getting a hold of sony , the unlocked lt28i does work on t-mobile 3g, which i currently have right now and am very happy with it, am in phoenix area which is one of the better spots for t-mobile
many websites had the specs wrong, i had gsm arena semi fix it but they havent recognized the 3 versions for the ion, there is the lt28i which is the international version(t-mobile compatible) , lt28at which is at&t locked and lacks the frequency needed for t-mobile 3g as of now, the lt28h should work also on tmobile and is capable of 4g speeds on paper but sellers that i came across couldnt distinguish which international version they had so i went with the lt28i, which is future proof for lte and t mobile reframe to 1900mhz for 3g in the coming months
my brother has the galaxy s3, synthetic benchmarks aside, when i have 3g and the s3 has 4g web browsing is almost the same speed, even though he has ics but its not a polished experiance like the ion
the phone is loud enough contrary to web reviews that dont know anything about the XLoud
screen is great, battery isnt the greatest but sufficient for a whole day
hope this helps
if you google any sony model followed by "white paper" you will get the accurate specs for it

I've got LT28i and it works perfectly well in Charlotte, NC where we have 1700 AWS. My average speeds are 7-9 mbps. I flashed Rogers Radio right after ICS upgrade. Unfortunately it does not support HSPA 42 only 21. Also when scanning for available networks I get AT&T 2G, 3G, LTE besides T-Mobile 2G, 3G.
2g, 3g, 4g, etc
From the White Papers on each phone.
LT28i: UMTS HSPA+ 850 (Band V), 1700 (Band IV), 1900 (Band II), 2100 (Band I)
GSM EDGE 850, 900, 1800, 1900
LTE Band IV and Band XVII
LT28h: UMTS HSPA+ 850 (Band V), 900 (Band VIII), 1700 (Band IV), 1900 (Band II), 2100 (Band I)
GSM EDGE 850, 900, 1800, 1900
LT28at: UMTS HSPA+ 850 (Band V), 1900 (Band II), 2100 (Band I)
GSM EDGE 850, 900, 1800, 1900
LTE Band IV and Band XVII
So, they all work 2g and 3g on AT&T which uses 850 and 1900 for both. Only the LT28at will not work on T-mobile 3g, which usually needs 1700. However, they do lease 850 from AT&T and have started reallocating 1900 in some areas for 3g- according to wikipedia's T-Mobile page. So, you may be able to get it to work in some places 3g for T-mobile, but what's the point if you can buy the LT28i and have the best possible 3g coverage through T-mobile? And in 2013 then, both the LT28i and LT28at will work on AT&T and T-mobile for LTE/4g, which T-mobile has not yet deployed.
Personally, I thought the LT28h was the international version because it will work 3g in any country. That said, the other two will work in most countries 3g, you would just not have all the operators to choose from. Japan and Some of Europe may be questionable for 3g on these phones. Look up List_of_UMTS_networks on wikipedia. I can't post the link, but it lists all the UMTS operators and the frequencies they use.
The Xperia V (LT25i) soon to be release will be tri band UMTS and pentaband LTE. Not sure it will work on AT&T and T-mobile without band IV, but the other bands contain all of the band IV uplink and downlink frequencies, so I would think it could be used. LTE is not widely used yet if you travel to off-the-beaten-path places like I do though. Until LTE is more widely deployed, I'm more comfortable with a pentaband UMTS.
From what I have read t-mobile does not have any 4g technologies implemented at this current time. They do call hspa/hsdpa "4g" although it is only a slightly modified 3g tech. I have the lt28h which fully works without issues on the higher speed h+ tmobile networks. I think the soon to be released sony TL will work on tmobile for there hspa/hsdpa networks and depending on how they use lte it may work in some markets once they enable lte which could come as soon as january in some markets but probably not until 2014. Either way by the time that tmobile implements LTE sony will probably have 20 more variants of the sony xperia s. But if you want a fast high speed phone for today's tmobile network the lt28h will work what you need to look for is a phone that has hsdpa 1700/2100 this is how to get tmobiles full speed. The sony t , sony tx and the sony tl should also work.
After reading this entire thread now I'm more confused. Ruling everything out, the LT28H is the perfect model for use on Tmo's faux "4G" until they deploy LTE? I need a decent replacement phone that runs on something other than EDGE using Tmobile. My Samsung Galaxy S 4G is slow and needs to be cut loose. Advice?
In the long run I want the Z or ZL but the LT28H will have to do for now.

Question I forgot to ask. Are all these the same phone? LT28H and LT28i are the factory unlocked versions correct? And the LT28at is just the AT&T branded version?

lt28i and lt28at has lte, lt28at does not have 1700 (band 4) spectrum for t-mobile 3g/4g.

So in theory those of us wanting the max speed while on T-Mobile would require us to get the LT28H? Just checking and asking tons of Q's before I drop 400 clams for a phone...

I have a Xperia SL lt26ii and a couple months ago it was only picking edge up, but as of recently in So Cal it's been picking up HSPA and when I went to florida it was getting 3g. Their high speed coverage is still pretty patchy around here though, their restructuring is taking forever.

Wow! But it is a nice phone. I'm also looking at the LT30a but can't find any online retailers that sell it.

Hi,
I have a Xperia Ion, Firmware .68 LT28i, rooted, I can't seem to get LTE working... I have tried using *#*#INFO#*#* and changing it to LTE but my carrier defaults to 3G (H symbol) I am in HK, and i know LTE is available, because i went into the carrier's shop and they tried putting my sim card in a Samsung phone and it showed up as 4G. So, are their any settings i need to change to get LTE? The download speeds are slow so i i don't think i am on LTE.
Thanks
Bolo

Feck. It seems LTE Band 4 and 17 are not actually supported by any of the networks in HK, What a waste of time this is then. LTE seems to be a bit of a mess with so many different versions of the same phone required to support LTE!
From what I know, T-mobile's 1900MHz UMTS Band II is around in my area, but I'm stuck on EDGE. Scanning for networks when I was running the stock firmware that came with the LT26i showed T-mobile 3G along with 2G (and AT&T 2G/3G), but clicking 3G never worked for me. Now I'm running FreeXperia CM10 and it only shows T-mobile and AT&T without a 2G/3G distinction in any of them. Is anyone actually able to get on T-mobile 3G on a non-stock ROM? If yes, then how?
Bump as I would also like to know. I'm torn between getting this phone or the LT28H.
I am wanting to know this too... I am on Straight talk in Dallas TX and really want this phone, but not if I cant use it on T-Mobile's 3G.

I got one on loan from Sony and it works on T-Moble's HSPA network but obviously not at it's HSPA+ which is 3.5G AKA: Faux 4G.

This is EXACTLY what I am looking for.
So I just flash Hong Kong ROM (to debrand), and LT28i radio to get AWS HSPA + LTE?????
If so, how?
I have obtained required ROMs.
LT28a is SIM unlocked.
I need it to work on T-Mobile USA

Hey, I picked up an LT28at not too long ago. It's on JB LT28h with LT28at bands on the T-Mobile network (so AWS 3G/4G, and 4G-LTE). I've noticed in areas where my signals might be weak, I'm stuck on edge. My wife's Lumia 521 (only has 3G/4G AWS) will show 4G reception and download speeds in these areas verify that speed.
Is the reception not that great with the LT28at or might it be something with flashing the radio form ICS LT28at to JB LT28h? Thanks!

That's because AT&T suppresses T-Mobile HSPA frequency, which is 1700. You only have LTE and 2g. In order to have T-Mobile 3-3.5G, you must flash LT28i baseband. You can flash Roger JB LT28i baseband or the same from ICS.
Regards.
Like has been said you need to flash a LT28i baseband. I know I read in this section or the Z section that the generic baseband is the one your after as I think Rogers still has the 1700 locked.
Hah... ****, I feel like an idiot, lol. Thanks you two. For some reason I thought the LT28at had AWS 3G as well. I wish *#*#service would give me the bands being used, but I think AWS 3G is up. I'll update when i find out for sure.
