Stupid Question - Tmobile TP2 radio on ATT 3G

I'm actually a little embarrassed to even have to ask this question, I'm also pretty sure I know the answer but better safe than sorry. Can anyone confirm that the Tmobile version of the TP2 is able to access the ATT 3G network? I'm 99% sure it will but that weird Tmob band makes me nervous, any input would be appreciated.

No, it will not. However the ATT version shouldn't be too far behind the Tmo launch so don't worry too much

no offense but what is the basis for your statement, the Tmob version will have
850/900/1700/1800/1900/2100 bands which are basically the ATT bands plus 1700, why would the Wing II not work on the ATT network?

Please show me where you found this data? Tmobile USA 3g network doesn't use the 1900 band for 3g; they use the 1700 band which is why Tmobile has to have devices specifically made for their network and why the Tmobile USA version won't work on ATT USA.
Again to clarify:
Tmobile USA = 1700/2100 for upload/download for its 3G
ATT = 850/1900 for upload/download for its 3G
Now Tmobile USA does use the 1900mhz frequency but that its GSM frequency it is not related to the 3g frequency. Confusing i know, but you asked.

One of the images advertising it does state all those bands, but does not differentiate which are for gsm and which for 3G (which can be misleading and confusing, ergo the clarification by jim_0068 ^). Though if they share the 2100 I have no idea whether you can get limited functionality or if you HAVE to have both of them. *shrugs*

actually this is not entirely true either,
AT&T is using 850 and 1900 Mhz for their 3G network,
it was revealed recently that they are pushing the 3G network to the higher frequency (850) and plan to have the 3G completely on 850 by 2010.
if AT&T is using 2100, we would've been able to use the european HTC devices which has the 2100 band.

As far as I'm aware:
GSM: 850/900/1800/1900
UMTS:1700/2100
And therein lies the problem... While it supports all the bands that would be required, only a small subset actually apply to a 3G connection/signal...
Minimally, that would be the specs for it to work on T-Mobile, and quad-band GSM is just standard on 99% of phones these days...

You're correct and i edited my post it is 850/1900 for ATT US 3G

I gaurantee you that the T-Mobile Touch Pro2 will not work on ATT's 3G Network At All... the frequencies for ATT will only support the 2G Network and therefore only phone calls and text messaging will work.

let's not go that far, let's not forget gprs (same speed as dial-up) and more importantly EDGE (for some that's more than enough).

when I go into the phone settings -- band I have these options on the Tmobile TP2:
GSM (900+1800)+UMTS(900+2100)
GSM (1900+850)+UMTS(1900+850)
UMTS(2100+800)

hmm, now I think the T-Mobile Touch Pro2 works on ATT's 3G Network.
It should also work worldwide too.

oooh, European bands, "standard" North American bands (they're not really standardized, neither in the US nor Canada and Mexico is barely getting 3G into place), and no idea what the last one is for, sounds like cdma...

hmmm why is there 800 MHz?
Obviously this is some bull**** because it supports all of the 3G frequencies of worldwide carriers and american carriers.

Sorry for the horrible pictures, using a g1 to take them. I love watching people jump to conclusions.

I think those numbers are for software only, in fact you probably don't have the hardware to support the frequencies of the wrong carrier.

seems that 800mhz is for Japan
and it doesn't allow for all of the North American bands (it's missing the 1700 one).
Could be just a software thing without hardware support, though that might be a tad odd, any way to check if it is?

My Xperia X1a shows UMTS (900) even when I check the settings... IN FACT only the X1i supports
It's very likely that the numbers you are seeing are actually all of the frequencies that are "summed up" and therefore the TP2 for T-mobile does not have the actual hardware.

Those options have been around with the custom ROMs, I have that too on my Fuze, if your hardware doesn't support it then it'll just be an eye candy.
Bottom line is this, if you want to utilize AT&T's 3G, then you'll need to wait for AT&T's Fortress because you need the 850 and 1900 band (UMTS band II). If you want to use T-mobile's 3G you still need a TP2 that has the 1700 and 2100 band (UMTS band IV), and no you cannot use european TP2 to access US T-mobile's 3G band because european's (and asia's) 3G utilizes UMTS band I, they are on a slightly different frequencies even though they are categorized both on 2100Mhz.

[Q] Is the Samsung SII T989 support HSDPA 850 ?

Hi,
I was looking fot the specs at gsmarena and it says that is HSDPA 850/1700/2100 capable, but in another sites, they said that is only 1700/2100.
Can someone confirm me that please.
Thanks.

The phone`s box states it is HSDPA 850/1700/1900/2100 capable. I know data works with At&t, so it has either 850 or 1900 HSDPA frequency but i am not sure if it has both or either one.

The Thing is that Im from Claro Dominican Republic, and is only HSDPA 850, I really need to be sure in order to buy the phone.
Thanks.

Well as long as it is on the box, we should rely on that info. You should not have any problems IMO.

it does work it's been proven already by many that has travelled to Europe on 850

actually most of the Europe is on 2100, of course it depends on the carrier but like 60% of the Europe is on 2100.

Was it a mistake bringing this phone to Israel?

I live in Israel. I used to live in the US. Last time I was in the US I bought this phone and brought it over. I did my research beforehand and knowingly purchased the phone assuming I would have full compatible with Israeli service providers...
Now, I'm not so sure anymore. I just tried the phone today.. maybe 5 hours of use. Still have the default OS installed. No root or anything. The signal seems to fluctuate going between Edge and higher speed networks.
Here's what it says about Cellcom on wikipedia:
Cellcom eventually sought to replace the 850 MHz TDMA frequencies it owns with standard 900 MHz GSM frequencies but Pelephone and Partner (Orange) petitioned the Ministry of Communications to deny this for technical reasons. This put Cellcom at a disadvantage since though most of its users had converted to GSM, they were not able to make use of the lower frequency's better in-building penetration and greater cell reach.
With its entry into 3G wireless services Cellcom demoed the first mobile video call in Israel. Since the beginning of 2006, Cellcom began deploying a 3G UMTS-2100 network nationwide which by the end of 2007 covered than 87% of the population. Cellcom was the first in Israel to launch an HSDPA network (also called "Generation 3.5") nationwide. In 2011, Cellcom began to deploy UMTS services in the 850 MHz band, employing unused capacity in that frequency range since it had very few TDMA customers remaining. The Israeli Ministry of Communications has approved Cellcom's plan to shut down the TDMA-850 network on 31 December 2011.

I just put the SIM card back in my old international Galaxy 2 i9100T and it'll fluctuate between HSDPA: 8 and HSPA+:15. Also it displays an H icon in the status bar (I don't think Resurrection rom is capable of displaying an H+).
Anyway, I'm going to put the SIM back in the Galaxy 3 t999. It now fluctuates between EDGE: 2, HSPAP: 15, HSPA: 11, and UMTS: 3. The signal is shifty and only displays a 3G at the top, no H like the international Galaxy 2.
Here's what wikipedia lists as the differences between the two models of the Galaxy 3 (standard international i9300 and my t-mobile t999):
Model GT-I9300;
2G networks: 850, 900, 1,800, 1,900 MHz GSM / GPRS / EDGE

So what do you think is going on??? Doesn't the t-mobile Galaxy 3 t999 support all the networks that Israel currently has operating???

I took my T999 to Israel about a week after buying it in the States.
While vacationing there, I got an Orange SIM with a local number and a 5GB plan.
Everything was working fine. My phone was on 3G almost everywhere in the country, and it rarely dropped below three bars.
Is your phone unlocked? Could it be a Cellcom problem? Try borrowing a friend's Orange SIM and see if it works any better.

Yea it's unlocked. Even despite the speed issue I'm starting to think maybe I should have gotten the international version, there's nowhere near as much development for this version. Maybe I can trade?

[Q] Can I use a Korean note 2 in the US?

I recently purchased a galaxy note 2 in Korea and I would like to bring it back and use it in the states with AT&T. I read that 4g would not be compatible with the phone but 3g will work? I plan to use this phone for business and I realized the 1 is not designated as voicemail due to it being a Korean phone. Is there way to add this feature on? Are there any other features that I will not be able to use with AT&T? I realize I won't be able to watch tv on my phone anymore.

I don't want to root it and I prefer to keep it stock. I just need to know if the phone will work with At&t's 3g network. It would also be nice if i could fine a way to check my voicemail.

If that's the international version Note II check and see what frequency's it supports,and compare to AT&T or T-Mobile's. International devices are not carrier locked
If it's a branded phone meaning you got it from your cellar carrier, It could be locked to that provider only.
If your using the unlocked phone, look up the specs on your device and see what it supports, if it matches up to the above frequencies you should be good

You will likely not get an answer from the OP...
Do a general search for info on the Korean note threads...as we have 4 or 5 that may help you in getting your answer....

Just reading the specs I would go with T-Mobile, Faster HSPA speeds if you decide to keep your amber brown. Only downside is T mobile's coverage isnt as good as AT&T but if you re in a major city it shouldnt be a problem.

Unlocked HTC One M8 - AT&T Issues?

Hi everyone
Today i just picked up an Unlocked HTC One M8 verizon branded
I took the phone to my carrier AT&T picked up a nano card, left AT&T and installed
I was able to receive calls and text and also call out and text
My internet is not working no 4G LTE. I went back to to AT&T and they told me it will not work with AT&T
When i swapped phones, data plan checked out ok. They installed the right one from my previous phone. AT&T shows up on the phone as the provider
Is there something i am missing that ATT would not tell me about getting internet? Is there a tutorial someone can link me to?
Thanks

APN settings would need to be changed. If I were you I'd just look into getting s-off and flashing a custom rom

Verizon's phones use CDMA, and have different radios than AT&T, which uses GSM phones. While both have LTE support, unfortunately the supported bands don't perfectly overlap:

Unfortunately, the short answer is yes. The slightly longer answer is that it will "sorta work", as long as you are in an area whose towers your phone will work with. I'd sell it and get the GSM version if you are sticking with AT&T.

The phone should work on 3G (WCDMA) as AT&T uses 850 and 1900 MHz bands, which according to the above listed band specs, is supported by the Verizon variant. You will need to manually enter the proper APN info.
Whether LTE will work is questionable. AT&T uses 1700 Blocks A, B, C, D, E; and additionally 1900 (Bands 2, 4, and 17). Verizon uses 1700 Blocks C and F (bands 4 and 13). And its not clear to me what Blocks on 1700 are supported by the Verizon variant. As mentioned above, it might work in certain AT&T regions, but not in others. But again, you will need the proper APN regardless.
http://en.wikipedia.org/wiki/List_of_LTE_networks
Lesson learned: You need to do the proper research before buying a phone from any source other than your carrier in order to guarantee proper band compatibility.
