Question on purchasing a Tilt

Ok well I am considering purchasing a unlocked AT&T Tilt, but I have been reading a bit about the 3G. Currently I am a T-Mobile customer and have read they will be operating on a different band frequency for their 3G. T-Mobile will be using 1700/2100MHZ while AT&T operates on 1900/2100MHZ. Will the 3G on the phone still be compatible?
Please someone clear this up
Appreciate it

Kaiser uses (under the Band options for the phone settings)
GSM (So gprs, edge) 850, 900, 1800, 1900.
UMTS (3G, HSPDA where available) 800, 850, 1900, 2100.
So it would be partially compatible, but only on 1900 cells, not the 1700 ones. These might co-exist like in the UK where some operators use all the frequencies for better bandwidth, or they might not. I'd check with T-Mobile what frequencies are operating in the areas you'll use the phone.

Well I live in the US and they still have not rolled out the 3G network here, they said sometime by summer. So if they use 2100 then the 3G still should be able to work? Since they still will be using the frequency except the 1900.

T-Mobile 3G Los Angeles Oct. 23rd launch

So good news for all Diamond euro owners in LA (and other places of course)...the tmobile network supports the 2100mhz band for 3G so no need for a US version!!

Sorry if this is old news, but i just realized it =)

this is great if true?
T-Mobile devices use the 1700Mhz/2100Mhz frequency band (for 3G) and I thought Europe 3G devices use 900Mhz/2100Mhz. Could U clarify further...

you said it correct...tmobile does use 1700mhz/2100mhz, and the euro diamond supports 2100mhz which should work since tmobile will be using it...i spoke to a tmobile tier 2 rep, he confirmed it as well...

That can't be right. T-Mobile AWS 3G uses the 1700 MHz band for uplink and 2100 MHz for downlink. I doubt T-Mobile US set up aside any channels in the 2100 MHz band as uplink channels.
It's kind of academic, as I can't get 3G on T-Mobile USA using a Euro Diamond in NYC, where we've had 3G deployed for a few months now. I've never heard of anyone else doing it either. Oddly, there's a "UMTS(1700)" selection in the band settings in the phone control panel, but if I try selecting that, it just jumps back to using T-Mobile's normal PCS band with EDGE for data.
If that tier 2 tech can get you onto AWS 3G with your Diamond, definitely let us all know about it, but don't get your hopes up too high.

AWS?? well the tier 2 tech did say it...i dont know if he was just talking out of his ass or not...but we'll see in the coming weeks...ill try to get tmobile rep on the phone again to ask them how i can get it...or if i can, even though its supported..

As I understand it, if a phone says it supports 2100 it is referring to the UMTS Band 1 used in Europe which is 1920-1980MHz Uplink & 2110-2170Mhz Downlink (see UMTS Frequency Bands - Wikipedia). The 1700AWS Band (UMTS Band 4) uses 1710-1755MHz Uplink and 2110-2155MHz Downlink. So, while they do overlap some they are not identical (A Visual Guide to AWS - PhoneScoop)
So, I don't believe that a phone with 2100 EU support will work with T-Mobile 3G because it doesn't support the 'right' 2100 nor the 1700. Likewise, I don't believe that a phone with 1700 support will work for 2100 EU.

If you want to get technical the "US" Diamond won't work for 3g on T-Mobile either. The 3g band is only for 850/1900. (so i guess we're screwed either way) I'm in Salt Lake City and I don't believe Utah is slated to get 3g until 2009 at this point. I bought the diamond knowing full well that 3g was going to be a slim possibility on this phone. However, a user with a DIAM100 is claming that he's been getting 3g service on T-Mobile in NJ. He said that he'd post screenshots.. I don't know if he's done that or not. I guess all we can do is wait and see.

Do you know who this user is? maybe i can PM him and get some details...i knew i wasn't going to get 3G with the diamond, but after talking to the rep. i kind of want to look into it more since there may be a possibility.

Honestly I'm gonna go ahead and call BS on him for that, I've never heard of anyone getting T-Mobile 3G and I know quite a few people with the Diamond/Raphael on T-Mobile in 3G areas.

I have the USA sold "quad band" euro diamond distributed by htc USA. This is essentially re-flashed euro diamond hardware sold to support american networks, not the 850/1900 newest USA 3G diamond compatable with AT&T. I have looked into this issue and also talked to T-mobile and there seems to be alot of confusion regarding T-mobile's AWS USA 3G network (or maybe they have simply confused me). Here is what I have found out: Assuming they are correct, they are telling me 3G voice for T-mobile usa runs in both the 1700 AND 1900 mhz band, and therefore my euro diamond shoud be supported at 1900mhz for voice 3g support. This 1900mhz is part of the "quad band" voice radio hardware on the euro diamond. Data (AWS 3G for USA) "HSDPA" , which T-mobile has not yet released, runs in the 2100mhz bandwidth, and Data AWS "HSUPA 3g" runs in the 1700mhz bandwidth. Therefore my hardware would not support HSUPA @ 1700mhz, but would support the HSDPA @ 2100mhz. As to the idea that euro bandwidths are different than USA bandwidths, well apparently they are. For example "2100mhz" networks in europe might be actually using 2110mhz-2170mhz, whereas in the USA T-mobile's network may use 2100-2140mhz actual bands. However because these are close and still in the 2100mhz band, there should still be compatability with 2100mhz hardware radios regardless of networks varying the bandwidth slightly.
Of course this may be too optimistic, but it would be very cool if true and I am hoping for the best .

Unfortunately, they've provided you some bad information. Each frequency band/range has a pair of uplink and downlink frequencies - you can't use one without the other - you have to use both. Generally, the uplink and downlink frequencies are relatively close to each other however, the 1700 AWS band has uplink and downlink spread quite a distance apart. Uplink is in the 1700MHz range, downlink is in the 2100MHz range and both have to be used. In the US, 1700 & 2100 is essentially one band.
1900MHz (the PCS band) isn't 3G for T-Mobile (although they technically could put it there at some point.) Right now, 1900MHz for T-Mobile is EDGE voice and data. Most other carriers do have 3G on the 1900MHz band, T-Mobile just doesn't have enough spectrum available in that band.
In short: A phone that supports UMTS 2100 will not work for T-Mobile US 3G. A phone that supports AWS/UMTS 1700 will work for T-Mobile US 3G but not for European 2100 3G. (And 1900MHz PCS will give you traditional EDGE on T-Mobile US.)

LG Thrill is same as LG Optimus 3D?

I have been posting in the optimus forum for help. I just noticed last night in a topic yesterday that LG Thrill and LG Optimus 3D are the same, except Thrill is 4G.
My phone is called LG Optimus 3D p925g, it's from rogers and I got it October 2011. It's 4G.
is mine the same as Thrill?
What happens if I use LG Optimus 3D 3G roms on a 4G?

Nothing happens. It's the same.

ok Thrill must be an american brand name or something.
when I flashed cyanogen mod ROM I remember seeing my 4G turn into 3G icon. Does it actually change to 3G or no?
also is this forum more active for help? I wonder why they have 2 forums if 4G/3G is only difference.

It's not even real 4G though. So it's all good.
The other difference is that the basebands are different.
One is international, the other is not.

not real 4G? What are you talking about.
I don't know what basebands are so okay.

Well if it says 4G, you're getting almost the same speed as 4G. There's a detailed explanation somewhere. I gotta find it.

Its 3.5g the way i have it my p925g. Always says 4g i dont know why even if i dont havr 4g speeds

4G implies 4th generation technology and standards. Ignoring the fact our '4G' is actually HSDPA+ (which is pretty much what 3G was supposed to be, but they did the same marketing BS with 3G)... we are nowhere close to the simple basic, no BS 4G standards of 100MBPS+ data speeds, with true multi-tower connections.
As well, all 4G means for most GSM carriers is that the phone has the HSPDA+ protocol enabled, and the towers in that region have the same... which is a simple software upgrade. You could be on a 500Kb connection, but they call it 4G simply because it has HSPDA+ protocol delivering those 2G speeds with a 3G technology.
The closest thing to true 4G on the market is LTE, which is totally new radio technology and tower technology, not simply a software upgrade that increases speedo's top speed from 5Mbps to 45Mbps, even though the motor is still only capable of 2Mbps.
The motor, btw, is the tower backhaul, and that is the real bottleneck in all of this and is what will determine your actual speeds. As it stands, there isn't enough hard line bandwidth out there to give true 4G speeds, and likely will be 5+ years before there is.
By then we will be on "6G" and some will still be running sub 1Mbps connections despite the hype.

ya we got lte phones hear now system isnt even up but rogers is claming its going to be 150mbps downloads

The Only difference
Thrill 4G Networks GSM 850 / 900 / 1800 / 1900
HSDPA 850 / 1900 / 2100
Optimus 3D networks GSM 850 / 900 / 1800 / 1900
HSDPA 900 / 1900 / 2100
HSDPA 850 / 1700 / 2100

maybe it is
HSDPA 900 / 1900 / 2100
OR
HSDPA 850 / 1700 / 2100
because 1700 / 2100 mean AWS and i don't think this phone (p925g) is aws

don't know what to do.
Hi,
someone offer me a Lg p925G from rogers which is unlocked. the problem: I live in france, when I put a french sim in the phone didn't find no network at all even a simple GSM; I tried to register manually to my network (the phone find it) but say that 's impossible to connect it. The phone is under the last V20C rom from rogers.
My question is simple: is that a hardware problem with the frequencies? or just a problem from the rom?
thanks a lot!

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.

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] 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?

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.
