I just figured this out after getting the plan, stupid me
Is their AAAAAANYWAY, i can get 3g on this phone though tmobile?
If not im going back to att
You have to buy a T-mo phone. Only T-Mo phone has 1700Mhz AWS band.
T-mobile phones use the 1700 MHz 3G band, as stated in the previous post. The AT&T Captivate doesn't support that band, it only supports 850 MHz, 900MHz 1900 MHz, and 2100 MHz 3G bands. The reason that you are able to use the Captivate on T-mobile at all is because the Captivate is a quad band GSM phone and that is what it can back down to for voice and 2G data if 3G is not available.
Next time just post in one spot... not 3 to 4 you will get a responce you just have to wait...

I want a 3g enabled smartphone/PDA for t-mobile, not the G1 dont like it. T-mobile 3G uses bands 1700 Mhz and 2100 Mhz right? So if i buy a phone that supports HSDPA 2100 Mhz will it work on the t-mobile 3G data network?
t-mobile is a gsm network though, so i don't know that an hsdpa phone would work with them (first of all no sim slot)
tmobile's 3g is new and not fully released so it would be difficult to find a phone that supports their 3g (you won't find anything but the g1, and you couldn't unlock a phone from att to support there 3g because the bands are different)
This is my understanding, but if i am wrong you guys can correct me
Im thinking of buying an unlocked GSM phone (nokia e55) soon, but im confused by GSM and UMTS because ive never had a GSM phone before. heres what (i think) i know:
Dual band 3g: 900/2100 mhz, will work with tmobile US, but only on the 2100 mhz spectrum, means no roaming.
tri band 3g: 850/1900/2100 mhz, supports tmobile and at&t, the ideal type of GSM for US.
Quad band: not sure.
fortunately ive been able to find quite a few triband e55's, but i just want to make sure i dont buy a phone with no 3g (i would NOT be happy).
btw, tmobile is the carrier im looking to change to soon, so triband is what i think will suit me best. corrections welcome.
I got Nexus S on ATT and I have tried it with a TMobile SIM (got surprised because phone isn't locked...) but it works on 2G only.
I'm wondering if it will work properly (as 3G) in Europe. Does it cover 900 and 2100?
What is ATT's data frequency? Is it 2100?
thanks !
I'm gonna reply to my own topic: according with Wiki ATT uses 850 MHz and 1900 MHz for UMTS (3G) that means ATT (unlocked) phone will work as 2G in Europe (2100 MHz)
On the other hand, T-Mobile's frequencies are 1700 MHz (uplink) and 2100 MHz (downlink).
Does it mean a T-Mobile phone will be able to work properly on Europe's 3G networks (2100 MHz?
I work for Tmous retail sales and we have never really been taught anything about bands. Ive been pretty curious myself since some customers come into the store with AT&t phones asking about tmo service. I have been instructed (by a fellow retail associate) to tell them that no At&t phone will ever have 3G on tmo ( I assume thats just the safe answer though).
real question!
in terms of 3G/4G (hspa+) what bands does tmous use?
same question for AT&t.
To tie that together. ex: If a phone from At&t hypothetically has capabilities to use the same bands as tmous and is unlocked, can it get 3G/4G service on tmous?
i did search around and didnt find a very clear answer so i figured i'd start a thread, im sure other noobs have the same question.
T-Mobile uses 1700 2100 MHz bands for 3G/"4G"
AT&T uses 850 and 1900 MHz bands for 3G/"4G"
Yes if a phone has all those bands for 3G, and it's SIM unlocked you can get 3G on other cell company.
The T-Mobile Vibrant actually has those AT&T bands too, if you SIM unlock the Vibrant, you can get 3G on AT&T.

It's very rare to see a phone that supports both T-Mobile and AT&T 3G bands.

Thanks for the clarification. In hopes that im not being a further nuisance, I was wondering, what about a phone that has 1 of the matching bands?
T-Mobile USA is using the 1700/2100 Mhz bands for 3G (UMTS)
T-Mobile Germany uses 1900/2100 Mhz for 3G (UMTS)
If you couldnt tell, im considering buying an iPhone (to develop on for fun). Will a phone that uses 2100 Mhz only be usable on USA towers (for 3G service)?

No it will not get 3G
So yesterday I flashed this phone to ICS, its great, thanks guys!
However, I have a question about radio (I'm a software guy not a hardware guy).
Apparently, this phone supports Triple band UMTS 1700 1900 2100 MHz.
Rogers Wireless in Canada 'operates on the frequencies of 850/1900 MHz'
So, why can't I connect to Rogers Wireless with 3G speeds on the 1900mhz band? Does the phone require both 850 and 1900 MHz UMTS to operate 3G on a 850/1900MHz network?
The best connection I can get is EDGE and it's painfully slow...I bought this phone before I had a data plan with Rogers, so I never quite realized this issue...I guess I could just switch to WIND I just want to understand why it cant operate 3G over the 1900MHz band
3g needs 2 bands, one for upload and one for download. And that's why most phones, for example, bringing to the T-mo network you won't get 3g/ 4g speeds since it would need both the 1700/2100 bands and not a whole lot of non T-mo phones have these bands. So in your case a phone to run on Rogers with 3g would need both the 850 and 1900 bands.
the hardware should be able to operate at those frequencies but its software locked to 1700/2100 or 2100 mhz, so if you want 3g/hspa you must be on an operator which uses one of those 2 frequencies

how do i software unlock it? Does cid uunlocking do this?
Although I haven't use it, I often see 4G Rogers data connection when I'm in Wind's "away" zone. Assuming there are no other models of MT4GS (with different radios) I'm rather sure this phone can use Rogers 3G network.
