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.

how do i get my 3g connection to work?

so i bought a unlocked phone on ebay bout a few months from now. i live in canada, also im in rogers network and everything works fine except my connection. i can only go 2g/edge speed but not 3g!! i have a t-mobile phone unlocked.. anybody know what i can do to get a 3g connection? do i need to install a new image or rom!!!!? please help

You may be out of luck on 3G. To the best of my knowledge, I believe Roger's 3G network runs on the 850 and 1900 MHz bands. However, the G1 runs on T-Mobile's 1700 and 2100 MHz bands. So Edge is the best you'll get (speed-wise).

T-Mobile's rollout of UMTS in the US will focus on the 2100/1700 MHz bands, whereas UMTS coverage in Canada is being provided on the 850 MHz band of the Rogers Wireless network. I think 1900 was added later as well.
My HTC HD is edge (2G only). But I use a lot of WiFi when ever possible.

Xperia V Download Speeds (US)

I recently acquired a Sony Xperia V (LT25i) that I am presently using on AT&T's prepaid mobile service in north Las Vegas, NV.
Tests conducted on stock (unrooted) Android 4.0.4 (Ice Cream Sandwich). Build number is stock 9.0.D.0.484.
Signal strength during tests was roughly -75dBm 21asu.
Mobile network type is listed as HSPA (with the status bar indicator occasionally displaying an H+ signal for a few seconds).
APN configured to wap.cingular (AT&T's GoPhone and MediaNet mobile web service).
Servers pinged were Tijuana and Las Vegas.
The attached pictures show internet connection tests using the SpeedTest android app. The first, showing no download speeds, is misleading because I do have data, though apparently the SpeedTest app doesn't like the proxy being set to wireless.cingular.com. The second shows my speeds after removing the proxy setting. Though it seems as though my actual data speeds are the same with and without the proxy. I'll be all right without it, I think.
Either the phone or my SIM card were not capable of picking up AT&T's LTE service, regardless of my service plan. I also don't know whether AT&T uses Band 17 (700 MHz) or Band 4 (AWS) in Las Vegas for LTE.
The Xperia V supports LTE bands 1, 3, 5, 7, and 20. None of which are currently deployed throughout the United States. I've theorized over at howardforums that a device that supports bands 1 and 3 (like the LT25i or the CDMA A1429) would be able to connect to Band 4, but I have no experience in this matter.
If anyone else is using this phone in the United States (especially with LTE service) I'd love to hear from you!

How's your APN looks like?

Is it possible to flash a LT25a firmware on a LT25i device, if so you have no more troubles I think?

If the phone can pick up ATT LTE, which I doubt, you still need a compatible sim card and apn settings.
Also, the ping in those tests are really high, even for the cingular apn.

Let me post external links please, already!

Correct, mrdommike, the apn settings for AT&T's LTE are different than the settings used for their prepaid service. AT&T does not presently support LTE on their prepaid plans.
Also, I agree, that the ping seems rather high. (Say, 3 to 5 times as high as it should be.) Not sure what to do about that, though. Maybe part of the reason is because the phone can't pick up AT&T's 1900 Mhz 3G band, and can only use the 850 Mhz 3G band in the U.S?
The apn settings are the default cingular.wap. I'll post them here:
APN: wap.cingular
Proxy: NOT SET (Ok, so this one's not default, as I mentioned in my original post. I had roughly the same ping with and without the proxy, however.)

Also, datagubben, the Sony Xperia V did not garner a stateside release. There is no AT&T-specific LT25a model, or any other model designed for primary use in the U.S.
That said, though it's still fresh, I have actually been quite pleased with the device's reception and service here in Las Vegas. There was a bit of a kerfuffle during New Year's Eve, but I never lost signal, and I imagine the calls and texts that went through so late were due to the excessive strain on the cellular networks. It remains to be seen how great the service will be at its main base of operation in San Jose.

Over here in the greater NYC and CT area, my V picks up HDSP+ signal pretty well too. Get downstream speeds up to 7mbps. I'm on the GoPhone plan as well, using the APN settings as described above.
LTE will definitely not work on the V, it doesn't support any LTE band used in the US.

Hey gftgy after looking at your apn, I think you should delete port 80 off the apn settings below the proxy setting. I have an unlocked arc s also with the cingular apn and I'm getting around 150-180ms ping. The only difference between yours and my settting is that port 80.

I plan on buying the Xperia V too. Can the users in the U.S verify if the V will pick up anything better than 2g service? I need it to at least be on 3g.
Thanks

AT&T, to my knowledge, runs 3G on 850/1900 MHz bands, where 850 is mostly used in rural areas and is also usually congested. AT&T's LTE network runs on 700 and 1700 MHz bands.
T-Mobile's 3G network uses 1700 and (in some places; a nationwide switch to this frequency is ongoing) 1900 MHz bands. Their LTE network uses 1700 MHz AWS band, replacing their old 1700 MHz 3G service.
Xperia V does not support 1700 and 1900 MHz bands for 3G.
Xperia V does not support 700 and 1700 MHz bands for LTE.
As such, you will probably be able to use it on AT&T's 850 MHz 3G network but the experience will leave a lot to be desired.

Yup. That's the same situation as my Xperia Z (C6603) - the C6603 works reasonably well in areas with solid 850 coverage, but there are places where I know that other devices can get HSPA+ service and I've dropped to EDGE.

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.

Cricket Wireless and Moto X Dev Edition.

The description says the phone uses the following bands:
3G UMTS bands: 850/900/ AWS/1900/2100 MHz with HSPA+ up to 42 Mbps (B5/B8/B4/B2/B1)
4G LTE bands:700/AWS/1900MHz (B17/B4/B2),
I'm looking to use this phone with Cricket, or other similar carriers such as MetroPCS in Jacksonville, Florida.
Before I purchase I can't seem to determine if this phone is compatible with those carriers and will achieve LTE/4G /3G reception. It's important that mostly 4G/LTE is possible as I get signal drops in my area without those bands.
Any help is appreciated. Thank you.

Google says yes.
