SK4G on AT&T? - T-Mobile Sidekick 4G

Is anybody using the SK4G on AT&T? Lets not start a carrier discussion other than can it get on ATT 3G bands? I believe the samsung vibrant can. Correct me if Im wrong about that.

I doubt you would find anyone using a Sidekick $G on AT&T
The 3G (UMTS) bands supported by the SK4G are Band I (2100) and Band IV (AWS1, 1700/2100).
AT&T uses Band II (1900) and Band V (850) (at least according to http://en.wikipedia.org/wiki/UMTS_frequency_bands )
So while you could use it with the 2/2.5G (GSM/GPRS/Edge) service of AT&T, you wouldn't be able to use it with their 3G network.

Thanks. I thought that might be the case since t-mobile owns the name sidekick and there is no international version of the phone.

Is it possible to flash the radio with one more compatible with the network the person is interested in using:

It has nothing to do with the radio. Its hardware based.

Nope, not possible. And wrong section.

1. Know your network.
2. www.gsmarena.com or a similar site. Find the specs and compare.
Edit: and if possible, a mod lock or move, preferably both.

i also picked up an at&t samsung infuse 4g...and i am searching for the best possible updates for this phone...will post here if i find something nice
its not that crazy of a question nowadays with carrier branded phones being so close to one another. you can actually flash a tmobile radio onto a skyrocket and have 4g hspa-dc through tmobile. but even if the infuse hardware was capable of tmobile bands (which it probably isnt), theres no tmobile version of the infuse inwhich to pull a radio. so the answer atleast for now is no.

[Q] Can GS 4G do TMo & ATT 3G?

Hi, am leaving Sprint. Looking to get a used phone (no contract), that will work on monthly plans like TMo prepaid, Straight Talk (ATT)) w/out a contract. I'm reading good things about both the older Vibrant (SGH-T959), and the newer 4g (SGH-T959V). It's clear from my research that people are successuflly unlocking and able to go back and forth between TMo and ATT SIMs on the older Vibrant. What isn't clear to me is can this be done on the newer SGH-T959V?
Again, I don't care much about 4g. 3g on AT&T is fine. But while on TMo, the 4G would be nice.
Thanks!

Thanks Brandon. I will then pick up a used, older SGH-T959 (Vibrant), unlock it, and then enjoy the 3g flexibility of both ATT & TMo. It's strange, the T959V is supposed to support the same ATT 3g band as the regular T959, but I can't find proof of this anywhere.

I have SGS4G and am using ATT. I have 3G with no issues...
posted original question here by accident
I am using unlocked 4g on Cincinnati Bell wireless and the 3g works fine.
However I have not been able to get 4g at all on my phone. When I put a Tmobile sim in it works fine one 4g.
I get a little over 2 mbps download on Cincinnati Bell 3g.
You can just unlock it, I'm using mine on att right now. Only thing is you have a backup sync for T-Mobile instead of att.

3G on AT&T will only work one one of the two UMTS bands: 1900 MHz.
Note that the Vibrant 4G doesn't have the 850MHz band (the other band that AT&T uses for 3G data.)
I've seen a posting that there's a way to activate the 850MHz band, but I have not verified that this works. If anyone has got this working so you're working on both bands on AT&T with your Vibrant 4G, let me know.
As an addendum to my own post, looks like the consensus is that while the Vibrant has an option of selecting the 850MHz UMTS band, it actually doesn't enable anything:

I regret to inform you that this isn't going to happen. You said you have an i9020t from WIND right? WIND uses the CDMA network. Rogers, telus, bell, (and many others) use a GSM network. If you put in the Sim your phone won't read it properly. I'm sorry but it looks like you need a new phone unless you want to risk swapping hardware and destroying your phone. Even if you did swap parts I don't think it would work ad well as you think .
As suggested sell your Nexus you'll get a fairly good price for it. You could buy a used i9020a after. Sometimes used ones can have problems though.. I say you should sell it and find a way to get a new one

Sprint is the only carrier that sells the CDMA Nexus. Wind uses AWS, which is 1700 MHz UMTS (3G GSM). The i9020t has AWS, as well as quad-band EDGE (2G GSM) for legacy networks.
As far as i can tell, if you want 3G, your only other choices are Mobilicity and Videotron. If those aren't available, Rogers is the only 2G GSM carrier I could find. Neither Bell nor Telus would be an option. They use CDMA for 2/3G and 1900 MHz for 3/3.5G.
This is, of course, assuming that your phone is SIM-unlocked.

Really? I didn't know that. Many of the employees at WIND told me it was CDMA (of coarse I'm in Canada). People having a hard time with their jobs I guess . I was also pretty sure that telus and such were GSM. Have people began switching over?

P6200 US 3G At&t or T-Mobile?

I'm currently deployed in Afghanistan and ordered the 6200 to work with GPRS out here, sadly enough that's the only reliable data connection available. I googled at&t and T-Mobile frequency bands but I'm not exactly sure what I'm looking at.
Could someone please let me know which carrier I'll be able to use this on with 3G when I return home next year? Thanks!
Sent from my E4GT using xda premium
As long as it is sim unlocked then it should (technically) work with either one on 3G since AT&T uses the 850/1900MHz frequency and T-Mobile uses the 1700/2100MHz. The model you have (P6200) is listed for 900/1900/2100MHz frequencies for 3G.
It will work on both of them under 2G for sure since it is quad-band GSM.

This is just a guess based on what little I know about these things so I can't guarantee this.

I know one problem might be the micro sim card idk if att uses those at all. I guesse u could probably just cut a regular one

ATT uses micro sim, that's not an issue.
Frankly I find these LTE just getting to be ridiculously big. The HTC One S is the perfect size imo.
According to the FCC document for the t-mobile version, it's supports WCDMA 850 (ATT), 1700 (T-mobile) and 1900 (ATT,T-mobile). So I should fine on ATT's network as long as I put in the correct APN right?
Also looking for clarification on this...
It probably will, but it has to be unlocked and for that to happen, we need S-Off which could very well be a few months away. Why don't you buy the international, unlocked version outright? You also get your choice of colors (red/black as well instead of just blue/grey).
Wow, not a straight answer yet, YES and unlocked HTC One S will work on ATT 3G (1900mhz). No ATT LTE support. Contrary to above micro-sim is not a problem, att iphones use them and of course you can always cut it as well.

I thought it had the 850 band for 3G only. I don't see any specs that say it has the 1900 band for 3G. This tells me it will only work in places that AT&T has 3G on the 850 band. Does ATT use 1900 at all for 3G?

ATT uses 1900, in some markets, ATT uses the mixture of both, 850 has better penetration in urban areas (tall buildings ...)
I'm interested in the phone, but i'm going to be using it on ATT. Can somebody that has the device tell us what is the FCC ID?
Quick trip to Phone Scoop website, i can see that there are two FCC ID's associated with the phone. NM8PJ40110 passed the tests using ATT WCDMA bands (band II 1900 and band V 850) and T-Mobile bands (band IV 1700/2100). NM8PJ40100 passed only ATT bands. Both doesn't show any reference to any test on WCDMA 2100 (band I), which probably means that the phone doesn't support the international 3G band.
In short, theoretically, the T-Mobile's version of HTC One S should work on ATT 3G bands (WCDMA band II and WCDMA band V), however, the phone would not support ATT LTE.
Since the hardware is there (FCC website proves it, unless if the official T-Mobile USA version got pushed with different FCC ID that i do not know), the phone should work on ATT 3G, but nothing prevents T-Mobile to disable the ATT 3G radios in their ROM. I think that S-OFF would give opportunity to enable the ATT radios (if they are blocked)
We will see ...
Take care,
From my experience, the ATT radio is not blocked and works fine.
