Ok so I understand that by unlocking my phone (I used the SIMlock Remote Client for $20 from sammobile.com) I can now use an AT&T SIM card if I choose, but my question is this: Is it even remotely possible to make my current T-Mobile SIM card work on AT&T's network? Just so I can pick up better 4G speeds in my area because quite frankly, the 4 - 5 Mbps I'm getting with T-Mobile isn't cutting it, especially when I hear of people getting 25+ Mbps. Thanks in advance.
No... same SIM as carrier is a must...plus u might need to change apn's?
Plus if u go to *prepaid att* u won't get 4g speed only 3g......u must be on a plan to get 4G off att^^^

ATT customers can get 4G on a unlocked Tmobile S3. Tmobile customers can only get 2G on ATT's network with a Tmobile unlocked S3.

Umm, not exactly.
A T-Mobile S3 can get 3G on AT&T's network, but not LTE (4G).
An AT&T S3 can get only 2G on T-Mobile's network.

4-5MBPS is probably normal for your area and most of the US. People that are reporting 25mbps+ are in the few HSPA+42 areas that T-Mobile has. There's nothing wrong with your area other than T-Mobile doesn't offer those speeds there.

I think you were confuzzled. ATT unlocked phones will only get 2G on tmobile (Due to lack of frequency) but unlocked Tmo will get everything EXCEPT LTE on ATT network.

Correct, unlocking allows you to use any SIM you want.
AFAIK, there is no way you can use the AT&T network with a T-Mobile SIM.
Does anyone know if i can use an unlocked at&t gs3 on tmobile service??? I heard it will only get edge data.

Looks like Edge only. I just unlocked a GS3 for my dad and he's on Tmobile. Is there a fix to try and get 3G?
I have a T999 unlocked and I'm getting 3g and some times 4g like right now. Called at&t to check they said no lte but yes to hspa.

Unfortunatley no. I had to pay $19.99.
About two days ago me and my friend bought a cheap tmobile phone, cut the sim to fit his att gs3 called att and got them to unlock the phone, popped in the new sim and he was able to get 3g and hspa+ on tmobile's network with his att galaxy s3. we were both pretty surprised that it worked. he's running cm10 if that matters.

That is because tmobile is rolling out there hspa+ data service on the 1900mhz frequency slowly but surely and the att gs3 supports the 1900mhz bands.. The BEST gs3 to buy is the tmobile gs3 if i am not mistaken it suports all of tmobiles aws bands and all of att hspa+ bands. Unlock that one and you can use either network to its fullest minus the LTE.
BTW.. tmobiles aws coverage is pretty damn good in the north east and there data speeds are almost as good as LTE.

I just called ATT today and told them I would be travelling overseas and they gave me the unlock code for my GS3 and GS2. Gonna go get a sim today for the S3 and try out a unlimited monthly no contract plan.
I'm in Warren county and travel throughout northern and central Jersey for work but I know no one with their service. So you think I should be good signalwise? Like I said I know no one with the service but am willing to try it out for a month since they are 20 dollars cheaper than ATT atm

No it will suck because like I said tmobile is rolling out service on 1900 but it's still spotty. Unless you have a tmobile gs3 you will be disappointed . However if you can get a gs3 for tmobile or another phone that supports tmobile aws bands you will be very happy. The tmobile gs3 works fine on att after u unlock it.. But no LTE.

I'm currently on att with a note 2 and i've switched to t-mobile and will be recieving a new phone in the mail soon. Should i return it and just flash a t-mobile rom onto my current phone? or should i just sell my att one on craigslist and keep the new t-mobile phone? Any possible loss of features or functionality by sticking with the phone i have?
Keep the tmo one.
It dosent have lte yet, so hang on to att one too I suggest but tmo has added aws band.

I don't understand your answer to the OP.
I'm in the exact same situation as the OP. I'm with AT&T but they just took my unlimited data plan away so I'm probably going to switch to T-Mobile.
Are there any bands that the T-Mobile Note 2 has that can't be unlocked on the AT&T model? According to Wikipedia both AT&T and T-Mobile version of the Note 2 have AWS. I heard that you can enable the high speed bands on AT&T's model to work with T-Mobile. Is taht not true?

Tmo hasnt released the update to let tmo gnotes2 work on their lte network, because its not up and running most places... Possibly only update customers who are in Kansas City.
Not too clear if att gnotes2 with att specific firmware would work on tmo's network. Theoretically it should work, but their might be some radio issues that give u shoddy service. Unlocking phones is illegal now, so idk if u could sim unlock ur phone through att to work for tmo anyways. Might have to go through ebay or something to do so.

I moved to Charlottesville, VA recently and the Tmobile coverage is really awful. Is it possible to take my rooted Tmobile Note 3 and use it on the Verizon network? I know it works on AT&T as I put my buddy's SIM card in and was able to connect to the network, but Verizon has the best coverage out here.
If I have to flash a new ROM or change the radio that's fine, I just need to know how to do it and if it's even possible.
No, not possible.

It is impssible to use a T-Mobile phone on a Verizon network. T-Mobile and AT&T run on the GSM type of network and Verizon and I believe Sprint run on CDMA which aren't capatible. It doesn't matter if you are rooted or not.

I've seen several instances of Verizon customers using their Note 3 on Tmobile. Just thought it might go the other way.
Verizon LTE devices come SIM unlocked for legal reasons (Verizon made a deal with the FCC not to SIM lock their devices in exchange for being able to use LTE Band 13 700 MHz).
Some of their older/"first-gen" LTE devices don't support GSM at all (e.g. Galaxy Nexus). But all nowadays do. The Galaxy S4 and newer support T-Mobile's LTE band. LTE is a GSM-based technology, and people travel as well. So pretty much all of their phones are GSM-enabled nowadays. Same for Sprint (except their phones will reject any US carrier SIMs specifically).
Anyways, the answer is no. AT&T and T-Mobile devices don't have CDMA enabled. And even if they did, Verizon and Sprint don't allow competitors' phones onto their networks.
Hi,
I am thinking about moving my Galaxy S4 and moto RAZR from Verizon wireless to iwireless (a t-mobile affiliate). I understand that I need to unlock my phone but I am unable to find out if I move it to iwireless if I will still have 4G data. The iwireless sales rep said that I will still have voice and 2.5G service but couldn't tell me if I would still have 4G.
I was looking at this table I found on a site explaining how to unlock the phone but I don't know enough about the subject to make an informed decision.
Samsung Galaxy S4
Can someone confirm whether or not my Verizon S4 or RAZR can be unlocked to work with the iwireless/t-mobile 4G network?

It seems as though your grasp of the subject is strong enough to know that it might work as you'd like - and it might not. You need to call back and ask to speak to a CSR that actually knows what bands their service works on so they can give you accurate information. That's kind of their job...
Also -
Verizon LTE operates on Band 13 while T-Mob operates on Band 17, both of which carry completely different spectrums; this means no LTE on either of your unlocked phones.There's a slim possibility that you will get intermittent 3G but the most likely scenario is that you will get talk, text and 2G / 2.5G only.
Band 17? My Verizon branded S4 is getting T-Mobile LTE. I'm fairly sure its on band 4.
T-mobile is band 4 which is 1700/2100 mhz. The Verizon s4 is not capable of 1700mhz. But if you are getting 4G it may be because your area is using 2100 mhz. I am specifically moving to iwireless and I was told they use the 1700 mhz band.

Yes, I think all Verizon LTE capable phones are unlocked.
The I545 (Verizon S4) can receive LTE on band 4. T-Mobile serves LTE on band 4. The coincidence works well.

My RAZR MAXX HD definitely wasn't SIM unlocked... For the life of me I couldn't get it to work when I moved to ATT from Verizon... Not even GSM would work.
I just need to get some clarification from you guys. Are your VZW phones bought in the US and being in the US on t-mobile's or iwireless's 4g network. Because after I made the first post I went to the phone unlocking place in my local mall and talked to there techs, they said that the VZW S4 will not get 4g. I have also been doing extensive searches online and keep finding half saying it will work and half saying it won't. I have a feeling that the ones that work are working outside of the US as I found posts saying as such.
I read some where that the razr you had to flash the radio FW to get GSM to work properly.

I got my vzw S4 off craigslist but 99% sure it was purchased in the USA. I'm on T-Mobile's $50/mo plan.
Verizon's LTE phones are sim unlocked due to an agreement with the FCC when vzw purchased some bandwidth.
I think there was an update around 03/2014 that enabled band 4 on the I545. Then had to make some apn changes and tell the modem to use gsm/lte on band 4.
The one quirk I have is it will say "no service" after a reboot and until I make or receive a voice call. Then I get the "T-Mobile" instead of "no service" and things work as they should.

I'll have to go to iwireless and have one of the tech put a SIM card in my s4 and razr to give it a try.
The only options I have for the network mode on my s4 is
Global, LTE/CDMA, and GSM/UMTS. Can you post you settings?

I was just at iwireless today and tested my phone with their network and was unable to get it to work. iwireless is a t-mobile affiliate but they do not use 4G LTE in my area. Their system runs on a 3.8G 1700MHz which the VZW S4 does not have. I am told that they will be starting to switch all the 2G radios in the area to 4G LTE later this year, which should work with my VZW S4. So I am just going to have to wait till the end of the year and go back and test it again.

That phone was before VZW bought the band 4 spectrum and cut the deal with the FCC. All VZW LTE phones are SIM unlocked. Any AWS capable VZW phone is SIM unlocked and can use LTE on band 4. The S4 got it with an update last year.
I am probably going to do the $30 plan soon and plan to use my VZW S4. I am not going to port my number right away in case the service in my area sucks (doubtful, live in DFW in dense surburbia).
I went out off town this weekend and went to a t-mobile store and was able to get 4g service after adding the correct APN. But it is too bad that iwireless that is in my area does not use that band yet, they are staring to upgrade to that band later this year. Until then my s4 will only get edge service.

With the announcement of the T Mobile $100 2 line unlimited everything, I'm also interested in bringing my Verizon S4 MDK boot loader phone to T Mobile, but want to do my research first-- is it as simple as signing up for T Mobile and getting one of their SIMs and then-- would I be able to flash any of the ROMs in the S4 T Mobile Dev forum or is the T Mobile S4 a completely different device? Any caveats? Would I have to LokiDoki after the flash? Would I need to flash a T Mobile specific radio too (currently on i545vrufnk1)? Or is that all just overcomplicating things? Would i be able to just adjust the APNs on my current ROM after inserting a T Mobile SIM?

Quick reply to my post and for anyone else interested-- there's a post here that talks about using a 4.4.2 T-Mobile ROM by Fenny on the a Verizon S4: http://forum.xda-developers.com/showthread.php?p=57453019 I've tried it and LTE works great, MMS works properly, phone calls work as well. I'm on the Verizon i545vruamdk bootloader and Verizon i545vrufnk1 radio. The ROM is a T-Mobile m919uvufnb4 by Fenny.
