Buy a new Note 2 or unlock my current one?

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.

[Q] Moving S4 from Verizon to iwireless/t-mobile

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.
Bsliv, how did you unlock you phone?

Many Verizon phones are sim unlocked, so it's most likely unlocked as well

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.

I was able to get H+ on my s4 from Verizon to tmobile by changing the network mode to global and the App to fast.T-mobile.com

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.

I bought a Sprint lg g3 to use it in my country and it has the 4g network blocked

hi! I am form el salvador and I am really happy with this device, but I just discovered the issue that buying a sprint device implies when I want to activate de data network, it only shows GSM and it is really slow! some "experts" have told me that I need the MSL code form in order to unlock this network. I´ve tried many some methods posted here to get that code, but I failed.
can anybody help me please...

Even I am also looking for the same answers. Following this post.

someone please... I know there are many experts who know about it

please.. I am becoming crazy with no data

Different network frequency.
You will not get it to work in your country.

I have gotten an lg g2 form sprint work here in my country. But i cannot find the way the get the MSL code

Wow, are you stupid? You spent ~$500USD on a phone without even confirming you could use it properly?
Sorry if that sounds harsh, but 3 minutes on Google tells me that (at least according to posted info) only Digicel even PLANS deployment of an LTE network in El Salvador right now. So the answer is there is no '4G' network in EL Salvador- assuming Wikipedia is current.
If you're on TIGO, Claro, or Movistar there is no LTE at all according to that info Second, you chose THE WORST (least compatible) model of G3 you could possibly buy. If you want ease-of-use for non-standard markets or international travelling, you need to buy a D855 (European/International common model), D851 (T-Mobile) or maybe D850/852 (AT&T and Canada carriers respectively). Buying a Sprint or Verizon model of just about any phone ever is a recipe for disaster anywhere except their networks because their primary networks are completely different from everyone else. Sprint and Verizon started and continued using CDMA rather than GSM like everyone else, and their deployments of LTE now are different frequency bands and different signalling systems than everyone else too. Neither a G2 or G3 from Sprint will give you anything faster than 2G EDGE speeds for data.
tl;dr get rid of that phone and go find an AT&T D850 for South and Central American carriers, that way you could at least get HSPA 3G service.

T-Mobile would be better with unlocked bootloader but I agree he made a reckless decision

It cost me 300$.. I know I screw it. The point is, last year I got an lg g2 from sprint as well, but I took it to an expert and he got the msl code so that se could have access to the 4g data.. And yes, we do have 4g in some specific areas of our country. So the point is, how do I get that code in order to unlock it

Somewhere on xda I read a thread explaining how to add all bands for most qualcomm snapdragon devices. The good news is I saw a sprint G3 user say he was able to do it. The bad news is I did not save the link and will not find it for you. I suggest you start looking by searching all forums and type unlock bands or something similar, I think it was in a gs4 or gs5 thread. If you fail the xda searching do some google searching. If you do find it I wish you luck it looked like you need to get your hands dirty.

T-Mobile on verizon lg g4?

So i have a iphone 6 plus and someone offered me a verizon unlocked lg g4. Tmobile is my carrier and i understand that the g4 is unlocked but i was wondering how would tmobile be like on the g4? Will LTE function normally ? Thanks

edit: nevermind was wrong

The Verizon G4 supports bands 2/4/13. Most of T-Mobile uses band 4 for LTE, and on recent 2G > LTE converted sites they typically use band 2, so yes I'd say it would work well. The one they are missing is band 12, so you won't get any of T-Mobile's low-band spectrum.
You will likely also get an invalid SIM warning on your phone, since it's not a Verizon SIM.

My Tmobile branded Iphone doesn't have band 12 either so will my service be the exact as I have it on my crapple 6 plus ?

Should be.

Unlocked T-Mobile G3 on Verizon?

Hey guys,
I couldn't find a thread here on XDA in regards to this, but I am wondering if my T-Mobile LG G3 that has been unlocked by T-Mobile will work on Verizon....at all? This is not a personal choice, but more like I keep being asked by many in regards to my ad on Craigslist if the phone will work. I have done some research on this and found that the G3's LTE antenna can utilize a few select bands of Verizon's LTE, so data and MMS are my last worry. My main concern is voice and texting. COnsidering those are separate antennae, what should I know in order to inform possible buyers? I obviously do not want to be falsifying information in any way (literally against my morals; I was screwed over twice with smartphones and CL).
Again, what should I know. I seem to be finding myself using gsmarena.com to compare the Verizon G3 and T-Mobile G3 LTE band support.
Any help will amazing so I can get this phone sold! Thanks all!! :good:

According to willmyphonework the LTE will work fine but if they ever go anywhere without LTE, they will not have service at all. The CDMA part of verizon isn't compatible with the GSM edge capabilities of the T-Mobile g3.
