AT&T 850 MHz 3G

I've been searching around and I can't get a definite answer...
Can the vibrant pick up the AT&T 850 MHz 3G network? Is there any way to turn on this feature?

Yes. The 1900mhz I believe as well. Idk what you search but Google "Vibrant on at&t 3G"

Use SGS Tools. Select secret codes. Scroll down to band selection and it will give you all the options.

I've turned every band on, but I'm still only on edge...

Are you using the correct APN settings?

Don't really know what mine is set on but im running bionix v and my vibrant is unlocked and it works perfectly on 3g att so it will run on 3g

I can get 3G in other areas, but not here, which leads me to believe it's just a 850 MHz band.
I can take out the SIM and put it in an iPhone and it picks up 3G just fine, whereas the vibrant is stuck on edge. It's frustrating to keep having to reboot the phone to pop out the SIM

Its got to be unlocked doesn't it to work on att 3g network don't it?

Here we go again...
Here we go again. If you are referring to the T-Mobile USA Vibrant, it does not have support for 850Mhz UMTS bands. Period. The FCC says so. That is pretty definitive as far as I am concerned. It does not matter what some piece of software shows you. The hardware is not capable as it sits in the T-Mobile USA Vibrant. Search the FCC database for the Vibrant. GSM 850Mhz ≠ UMTS 850Mhz.

Pretty sure it's just 1900MHz. The FCC documents would have included the 850MHz band if it was really there.
Edit: Lol, yeah what he said.

Thanks for clearing it up now comes the dilemma of deciding whether to use the vibrant or an iPhone that uses the 3G speeds...
Sent from my SGH-T959 using XDA App

Tmobile Vibrant does have capability to operate on ATT 3G network.
I could get it working with iphone sim card.
Specification also includes ATT frequencies.
Att is using two frequencies for 3G.

If it don't run on 3g then why does my vibrant have a 3g data icon and is blazing fast on it?
Sent from my SGH-T959 using XDA Premium App

It runs on 3G in areas where AT&T uses 1900MHz for 3G. It runs on Edge in areas where AT&T only uses 850MHz for 3G.

No. No it can't.
Jesus Christ. Is it really that hard to not respond when you clearly don't know what the hell you're talking about?

Yes yes it can like I said I have a us vibrant and it switches between e witch is edge and 3g don't know how but it has a 3g icon that tells me that its on 3g if it not then why does it say 3g? And it is a beast on 3g on every once in a while it will have a H icon most of the time it SAYS 3G!!!!

Precisely.
The Vibrant does not have 850mhz 3g support. Only AWS(1700)/PCS(1900)/IMT(2100) 3g support.

Wow...just wow. Seriously, the FCC does not generally lie about things like this. And no, I don't think it is a big conspiracy in this case...lol

I'm not sure what this is about. Maybe it's just wishful thinking run amok...seems like most of these people either want to switch to AT&T or bought the phone intending to use it on AT&T, have since found out that it won't work in their area, and are refusing to ultimately admit to themselves that it won't work.
People like to think to themselves, "Well, maybe the FCC screwed up and I DO have a pentaband (or quadband?) 3G phone." The slightest bit of uncertainty encourages such thoughts...there are threads with jokers enabling the fake 850MHz menu selection and exclaiming, "OMG, I have AT&T 3G on 850MHz" when they already had it on 1900MHz. People who bother googling the question ahead of time will no doubt find some older, confusing threads.(Albeit they will hopefully find more and more threads with people like us saying "No, it's not in the FCC docs," etc.)
We should have a sticky or something about this lol.

Yes, I googled it and found conflicting reports which is why I came here to clear it up.
Thanks again

Att 4g or 3g

Is there anyway to run the mytouch 4g on att without it only being on edge network?
Sent from my Inspire 4G using XDA App

Pretty sure thats a no since the radios are built for different frequencies.

Unfortunately no, the radio in the Mytouch 4G only supports At&t's Edge Network.

probably not
iphone supports only EDGE on t-mobile network, so I assume the hardware designed for phones are only available to the network they were originally made for

if you want to run a MT4G on att go buy a desire HD. same unit but the radio's work on ATTs 3g network. thats basically the only way.

thats pretty much true there unless the phone is running quadband HSDPA. which is very rare nowadays. tmobile just kinda sucks cause they are running a rare HSDPA band while ATT runs a more mainstream. i buy phones from taiwan (HTC headquarters) for my family to use on ATT and their 3G is flawless.

Could you elaborate more on the Taiwan connection? I'm using this device now but would rather go back to the mt4g. Yet considering the match level of chess these companies are playing I need a Bobby Fischer type of device, of which seems to not be available in the YouEss
Sent from my LG-P999 using XDA App

It's quite simple. all the phones from Taiwan use the same 3g signal as att here for their smartphones. So you can buy phones from there and they will work perfectly fine on att networks here.

[Q] Information on network for motorola atrix

Please help me. I have a motorola atrix 4g. Unlocked. Rooted. Running on t-mobile network. I have 3g contract but all i am getting is edge (which is fricking slow). I know it possible for you to be able to change atrix automatic custom network (which is at&t) to work with t-mobile. Youtube doesn't help cause all i see is bell, sprint and metro pcs. I know it something with the radio. But i need your help thanks.

Do you have any friends who have tmo that you can ask their apn settings? That's my suggestion.

This is true. Carrier radio frequencies do differ in the USA. Wifi is the only high speed you'll get in the USA if you are not on at&t using the at&t Atrix.

Im so angry. But hope something comes up

If you're not locked into a t-mobile contract I suggest going to straight talk, they have a SIM for AT&T version phones and that should get you 3g. Or go for h20 wireless which should get you full 4g speed.

Lol, despite its name Atrix 4G does not have 4G... You need a carrier working on one or two of 850/1900/2100 3g frequencies.

i'd still consider HSPA plus more 4g than Sprint's so called 4g and that wimax thing the original evo has
and I'd consider verizon's 3G more like 2g hahaha

Man im disappointed u should have never brought this phone cuz a friend said I can hack the Motorola custom radio which was at&t to T-Mobile. But he was wrong.

HTC One Developer Edition

I have one, but I cant connect it to Verizon. Does this phone is working in Verizon CDMA network ?? If so how can I achieve this ?? Phone also missing the IMS (MEID Verizon version). Please help.

VZW generally will only activate a phone they sold you one branded with VERIZON.

Everybody keep saying it, but why ??
When I have purchased phone, I saw the MHz its supporting, which is Verizon range from 800 to 1900.
PS Anybody knows the programming menu code for HTC ONE ?

The developer version is a gsm device and Verizon operates a CDMA network. They are incompatible and the phone will not work.

Its not a cdma phone. Wcdma is NOT the same as cdma. Its a different technology. And even if it were, it ISN'T, Verizon won't activate non Verizon phones on their network. Way to spend some good money on something without knowing how it works....

Better put your One up for sale, while it's still hot. Or, think about changing your wireless provider.

Just switch to t-mobile, it's not worth paying what verizon is charging you. Then you can even keep your HTC One.

Its not a troll, I'm not so smart in this type of technology. In my mind it was very simple WCDMA is Docomo, which goes way ahead of regular CDMA, and Qualcomm made an support from WCDMA to CDMA2000, thats why I cant understand why Verizon CDMA don't want to support it.

Their service, imo, is not worth their prices. T-Mobile is catching up, and catching up fast. Unlimited everything for $70, no throttles, caps, nothing, and LTE is some areas already.

HTC ONE 64GB Developer Edition On Jacksonville Florida T-Mobile

I don't Have 4G or UMTS-3 on HTC One 64GB Developer Edition in the city of Jacksonville Florida on T-Mobile Network. All I see is EDGE. Anyone from JAX having the same issues.

Unless Jacksonville is a reframed network you should expect edge speeds, as the developer edition is missing the 1700 AWS band for T-Mobiles HSPA+ (4G)

Not much you can do unfortunately, you will have to wait for reframing to finish in your area. If the internet speed is important to you than your best bet is to return the device while you still can and opt for the T-Mobile version.

UNLESS... Someone posts the t-mobile radios and we can test to see if it woks on the dev edition phones. At that point all tmobile frequencies will work if successful
btw, no need for s-off. Please see http://forum.xda-developers.com/showthread.php?t=2245615
BUT! we need a Tmobile Radio to flash it with before we can use the thread method above!
