AT&T s4 on Tmobile - T-Mobile Samsung Galaxy S 4

I am looking to buy s4 but can't find Tmobile variant at cheaper price than compare to att version. I live in Chicago where I guess Tmobile has switched on the 1900 band. I think? If I were to purchase the att version would I get the same data speed as I would with Tmobile version. 4g or lte ? Please advise.

That's assuming you can even unlock it. I tried the other day and AT&T said that samsung hadn't provided the unlock codes yet.

[Q] Can you use this on AT&T network and vice versa when unlocked?

Hi,
I basically want to know if there is any difference between these devices, other than network provider lock.
Can you use the ROMs interchangeably?
I think the tmo model does support att's bands and u can probably interchange roms as well like on the tmo s2 and the skyrocket

We don't know for sure yet that the ROMs will be interchangeable. However, given that most T-Mobile phones support the 850/1900 NAM bands (GSM) needed for AT&T HSPA+, as long as the phone is unlocked it should work fine.

The Galaxy S2 did. Reading the specs page on the Tmobile website, I've come to the conclusion that the bands are identical to the AT&T variant's. I'm going to be doing the same thing.
Will hspa+ work? If so, tmo users who will be paying full price would be better off
Buying from att because its less than tmos full price cost.
Plus wireless tethering would work Because tmo doesn't have imei # of att phone.
Can anyone confim?
i would like to know this as well, paying 549 if a lot better than 639.

FYI only T-MO has HSPA +42 version of the S3 for those looking to buy from At&t.
anyone can confirm this?? does the gs3 from tmo works on att HSPA+ and vice versa and if the tmo gs3 works internationally on 3g networks.
All right,unlocked my T999 galaxy s3, put my AT&T micro sim in phone but I get no data. I can make phone calls no problem.Do I have to do anything with the APN settings?
Thank you!!
You need to make an AT&T APN. Also the AT&T version will not get 3G on T-Mobile without at the very least a modem flash.

O.K. just added a couple ATT apn settings still no data.any other suggestions?
By the way i have a 4g micro sim.Thought Tmobile S3 had ATT hspa+ bands.
Got apn settings from these forums.
Might want to do a lot of research before trying to flash an att ROM on tmo or vice versa. I heard the tmo phones are quad core.

did you flash an AT&T radio? you will probably need to do that.
how did you unlock your phone? did you just buy a code or did you try one of the XDA methods?

[Q] Tmobile or unlocked version? Which one?

I will most likely use this phone on Simple Mobile which uses tmobiles towers so the obvious choice would be the tmobile version, but would i benefit in any way by getting the unlocked version? Who is the unlocked version branded by? I dont want to make a mistake because a month ago i was about to get the unlocked iphone for my girl and run it on simple mobile until thankfully you guys tipped me off that the unlocked iphone was actually an at&t branded phone and will not get 4g speeds on simple mobile.
So, who is the unlocked version of the gs3 branded by? And which one should i get, tmobile gs3 or unlocked gs3?
International Sgs3 is branded by Samsung. I believe you would not get 4g, because of the different frequencies. The other option would be the Korean version of the sgs3. I do not know if that works though.
T-mobile is gonna be updating their 1900mhz which means the international s3 will get 3g data and iPhone users same...

Yes this guys right. Take a look for yourself:
ATT Galaxy Note Specs
T-Mobile Galaxy S3 Specs
ATT Galaxy S3 Specs
Notice how the Note and the T-Mobile Galaxy S3 have that 1700 Mhz frequency? Thats what T-Mobile broadcasts their 3G/4G spectrum on. If the phone doesnt have those frequencies, then it wont work no matter what you do.

That's different. It is a whole different phone with a whole different SoC.

Don't shoot this guy completely down. It will get T-Mobile 3g/4g as soon as T-Mobile refarms their network.

Yes, HSPA+ will be fine. But as you said, no LTE.

[Q] Does T-Mobile note2 work with at&t lte or hspa?

Guys,
I so want to buy the note 2 like today. However T-Mobile has no coverage in my area. If I buy the phone at full price I can get it unlocked. Am just wondering if T-Mobile note will work on at&t lte Or hspa+.

The phone does support HSPA+ on AT&T out the box since the bands are included. The phone also has T-Mobile LTE frequency as well, but is said to be locked down by software since T-Mobile does not have LTE up and running yet. I believe T-Mobile and AT&T do use the same frequency for LTE. Only way to know if someone unlocks their device and puts in an AT&T sim.
According to AnandTech review it WILL support ATT LTE. So how does a non-Tmobile user unlock this phone??? I want to use on ATT.
From the review...
http://www.anandtech.com/show/6386/samsung-galaxy-note-2-review-t-mobile-/9
One of the most interesting things about the Galaxy Note 2 on T-Mobile is that it literally is the same hardware as the AT&T Note 2 with LTE. Sure, the model number is different, but the T-Mobile Note 2 includes support for LTE bands 17 (which AT&T uses) and 4 (AWS, which AT&T has specced devices out for and T-Mobile has confirmed it will deploy LTE on). This is to my knowledge the first T-Mobile handset with overt LTE support, and thus a solid future-proof purchase if you’re determined to have a T-Mobile handset that will work with the carrier’s upcoming LTE on AWS plans.
In addition, if you unlock the handset there’s no reason it shouldn’t work on AT&T’s LTE network that I can see. I managed to unlock the T-Mobile Galaxy Note 2 but not before leaving the AT&T LTE market in Dallas. It does however work as expected on WCDMA 1900 in my own market on AT&T after unlocking.
Will the Note 2 work on streight talk as well?
I'm curious if the note II would work on att's 3g network. I'm with Sprint atm but I'm constantly roaming due to poor coverage so I'm assuming it won't be long till they nix my contract and paying $100+ for limited data is just ridiculous to me so I was going to go with TMobile but they only have.edge coverage around here no 3g so I was hoping if I went with TMobile I could use AT&T towers and actually have a decently priced plan with real service.

Im in the same boat im going thru the same thing I have both simplemobile/tmo and Att for work and i played with the international version and ofourse it was fine with my Att sim i didnt try my simplemoble/tmo sim at the time but im hearing the tmo version is exactly like the att and international one so imma just use my work phone/att to save some money(I use google voice so it doesnt matter what phone i use same number) and plus im suppose to get a discounted price so lets say i can possible be very happy this weekend!! but imma take the chance all the info i read states it will work with Att hspa+network so well see soon! if nobody tries it before me...

Make sure your using the right APN....... if your not using the right APN you won't get lte

Most likely your going to need the At&t radio just how At&t note 1 worked on t-mobile 4g by flashing the radio... maybe even a full on rom from at&t version since all the phones now come with the same hardware

[Q] moving from AT&T

Hi,
I'm thinking moving from AT&T to T-Mobile and was wondering if I can keep my unlocked Skyrocket (Galaxy SII), flash a T-Mobile rom,a modem, change the APN and be good to go.
Will I be able to get 4g?
Thanks for your help.

You still have to run a ROM from the skyrocket forum. You can use T-Mo modems or skyrocket modems
I use the T989 on At&t and get better performance with a T-Mo modem

Going to T-Mobile with their new "non contract" plan will save me $50/month without signing for 2 years, I think it's a really good saving

'Uncarrier' plans, remember? There are no free phones anymore (though there are ones with no down payments, but the SGS2 doesn't qualify). Even the absolute cheapest phones must be fully paid for now as shown on their website.
To the OP, I highly recommend getting a new phone. The i777 is good, but it lacks the 1700 band, so you won't have 3G. Choose whatever phone you like, though, personally, I intend to get the HTC One myself as soon as I can.
