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

T-Mobile and Samsung galaxy s 2

Sorry for posting it in the wrong section.. the only reason why I did that is because our vibrant is on t-mobile and I wanted to ask if someone knows if non us version of galaxy s 2 would work on tmobiles 3g or even 4g? Im not sure if the phone has 4g.
I just love how wide the screen is and how clean and simple the phone looks....
Willing to take other phone recommendations.
Thank you guys

T-mobile 3g/hspa+ bands
1700/2100
Galaxy S II Bands
HSDPA 850 / 900 / 1900 / 2100
it would get 3G on At&T but NOT T-Mobile due to the lack of the 1700 Band.
other then lack of 3G the phone would be fully functional. just stuck using GPRS/Edge for Data.

So in other words it would not be fully functional, and if on T-Mobile a waste of money.

Basicly.... unless u dont need data..

Would it really hurt them just to make it so it would run every frequency?

[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.

That entirely depends on where you are or what market you're in. T-Mo is in the process of moving all their HSPA+ service from the 1700MHZ band over to the 1900MHZ band in order to make way for its future LTE services. Most markets are still on 1700. If you're in one of those markets still, then the Int'l Note 2's HSPA+ will not work (because it does not support 1700MHZ HSPA+). On the other hand, if you're one of the lucky ones in a new 1900MHZ T-Mo service area, then you're all set to go!

Can't u wait a week for one from Tmo that'll work with all their hspa+ networks and future proof for lte with actual warranty for the same price? Heck you waited this long already what's another week for lte and warranty?

I'd wait personally. The T-Mobile one should have LTE too so you can take advantage of that once they start firing up those networks.

[Q] LG G2 D802 on T-Mobile US LTE

Hey everyone, does the LG G2 D802 work on T-Mobile's LTE network in the US? I found a great deal on one and thinking about purchasing today. Any thoughts would be appreciated! Thanks!

I got a great deal in Verizon one. I'm on t mobile $30 plan but I think its only 3g. Got 4mbps d 1.5 up.
Havnt been out yet signal weak.
Sent from my VS980 4G using xda app-developers app

d802 lte radio supports = 800/900/1800/2100/2600 MHz
tmobiles lte = band 4, 1700mhz
So no, only HSPA+
Pretty much the only non tmobile branded g2 that will get lte on tmobiles network is a canadian one iirc.

Have you checked the app settings? If hey are on the fast-tmobile blah blah blah (I know not technical) then I would imagine you getting HSPA+ hopefully

You would only get H+ on Tmobile reformatted 900/2100 and edge for when your not on those towers I would double check the 900 in your area

I'm curious why Verizon's VS980 does not work on T-Mobile's LTE 1700(4)? The phone has the correct bands.
Verizon - VS980
GSM 850/900/1800/1900
CDMA 850/1900
UMTS 850/900/1900/2100
LTE 1700(4)/700(13)

Does the UK D802 have LTE?
