[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.

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.

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.

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.

[Q] T-Mobile LG G4 (H811) on AT&T/Cricket, am I missing anything?

Posted this in the TMobile release thread but hasn't gotten any responses (might be the wrong place for such a question). Someone on another place I frequent posted this and I'm wondering if it's something one should be concerned about or if the bands missing are pretty much useless and won't make a difference to me? If it will be an issue for me, I will return the phone and wait for the official AT&T one to be released.
Thanks!
It will work in tmobile, yes. But won't you be losing some bands cricket/att use? I use cricket too and was trying to get the international model for this reason. With the tmobile version your missing some of the 3g and LTE bands that att uses.
H810 AT&T
GSM 850/900/1800/1900 MHz
UMTS 850/1900/2100
LTE Bands 2, 4, 5, 17, 29, Roaming 1, 3, 7, and CA
H811 T-Mobile USA
UMTS: Band I (2100), Band II (1900), Band IV (1700/2100)
LTE: Band: 2, 4, 7, 12, 17;

It won't make a difference.

Thanks for asking this question as I am bout to do the same. Just want to be sure that I will be OK w the T-Mobile phone on AT&T. I live in NY and will be using the phone mostly in the USA. If anyone has done this, your feedback would be appreciated!

Looking at your list, if you use a T-Mobile G4 on AT&T you will not get LTE bands 5 or 29, or GSM 850/900/1800.

AT&T uses bands 2/4/5/17/29/30 for LTE and 850/1900 for GSM. If you use a T-Mobile G4 on AT&T, going by your first post, you will not get LTE bands 5 or 29 or 850 for GSM.
This means is you will not be able to take advantage of AT&T's 850MHz LTE or 700MHz lower D/E LTE spectrum, or 850MHz GSM. AT&T's main bands are 5 and 17, so in some areas you will get reduced LTE performance, especially indoors and when far from the tower. You may run into markets that you only get 2G/3G in as well if they are using only bands 5 and/or 29.
In short, it will work, but it's not ideal.

The B/I/U text is the answer I was looking for. I appreciate it.
I'm going to rock it for a few days until the AT&T phone comes out and return the T-Mobile one since I have 14 days to do so.

Depending on your market, you may be perfectly fine, since you have the T-Mobile version I'd wait and see how happy you are with the service. The AT&T G4 costs a lot more.

Well, it just came. So I'll test it out with my Cricket SIM and see how it goes. But I'm leaning towards swapping it out.

Update, probably last one.
1) Put my Cricket SIM into the new LG G4.
2) Got a message saying phone was locked to network. Call support to get it unlocked.
3) Called support and they said because I don't have a T-Mobile account, they cannot unlock it. I'd need to go through a 3rd party to do that. BUT, if I do that, I can no longer return the phone.
I'm not going to bother with 3rd Parties and will just get an AT&T phone which will allow me to use my Cricket SIM without issue, plus have all of the missing bands. So, I am starting the return process on my T-Mobile LG G4, unless someone wants to buy it from me?

thanks for reporting all this. I'm on att but am out of contract, deciding if i upgrade to the att g4 or switch to tmo and upgrade there.
still not decided but I'm definitely not going to run the tmo on att, because my signal at home is 1 bar of lte if I'm lucky. the only hold back is obviously the bootloader. I've never had a stock phone for more than a day, eeesh.

No problem. That's why we're all here.
Same here. Now that I'm going to be waiting till June 5th for the G4 (AT&T release date), I'm hoping some progress is made in the next week for unlocking the bootloader. Must have root (for XPosed and a bunch of other apps).

I spoke to the guy at my local AT&T store who said they aren't doing an official pre-order but that he'll put me on the list to reserve one and I'll come get it when it arrives.

Man, I'm so indecisive lol. This is by far the 'craziest' a phone has gotten me since smart phones were invented.
I scrapped my plan of getting an AT&T H810 (which would work perfectly with my Cricket SIM) and decided to spend a tad bit more ($60 or so) and get a fully unlocked H815 model that has all the AT&T bands + others. Ordered it on EBay, should be here by the 4th which is actually a day earlier than the AT&T release (which is June 5th).

OnePlus 3 - Sprint 3G and Service Bands

Hello, I have a OnePlus 3 and have Sprint. Not realizing the device only supports GSM out of the box i found this thread: http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
Here one person was able to enable band 20 on a OnePlus One. I was wondering if it is at all possible to enable bands 10 or 1 for Sprint 3G. Or better yet bands 25, 26, 41.
I was also wondering, if I were to attempt this is there a risk of ruining the phone?

I recall band 20 was unable to be activated on the OPO as the device simply was not provisioned with a radio for that band.
Modding will not overcome hardware deficiencies.
Is Sprint a CDMA carrier? OnePlus do not support CDMA at all as the US is the only significant country using that outdated technology.

I do not think so.
First, I am assuming you have the international OPO. Go to willmyphonework.net and see for yourself; your phone is totally incompatible with Sprint. Even 2G bands are not available under its standard configuration.
At this stage you have two choices, return the phone for exchange/sell it or try and edit the hardware settings to make more bands available.
If you bought it new I would just return it rather than modifying the hardware setup.
If you want to tinker with it, you need to start here and also here and see will they unlock the bands you need.
Basically, follow the guides exactly and tick every radio band that appears in the programme and hopefully the bands for Sprint is among those available for your hardware.
I think I tried to activate band 20 4G and it did not seem to work. I have the international OPO.
The OP in the first link is a Chinese model, but the steps are the same.
To quote from the 2nd link I posted:
It will theoretically unlock:
GSM: DCS-1800/P-GSM/E-GSM/GSM-850/Railways-900/PCS-1900
WCDMA: Band I to XI
LTE: Band 1, 2, 3, 4, 5, 7, 8, 12, 13, 17, 19, 20, 21
PS: Even if they're theoretically enabled, some band cannot be used because of hardware limitation...

Even though all the above seem to be available to activate, some work, and some do not. [band 20 has a strikethrough, for example]

Buying from Samsung instead of carrier

Hey, I plan to buy my Galaxy so from Samsung rather than my carrier (ATT). I have a couple questions. Will I just be able to add the Sim currently in my Galaxy say or will I need a new one? Also, will I have to take it into the store?

Just put your existing soon card in and away you go. No need for anything else. It's what I did when I got my Note 8 from Samsung.

If you buy it from Samsung, the phone it's unlocked, so you can use any valid SIM (including the one you are currently using now).

Samsung has an unlocked model available on their website along with carrier specific models. I would think the carrier specific models are the same as the phones you would get at a AT&T or Verizon store. Correct me if I'm wrong.

I'd like to know this as I would like an unlocked bootloader but.... I would like the Carrier version for some additional features like VoLTE/VoWifi.
Right now I'm torn between just going to Best Buy (since in the states) or just getting it directly from Samsung.

The carrier versions will have the standard carrier bloat pre-installed.

I can't find the exact band specifications of each of the models... Does anyone know if the hardware/antenna chips will be the same on T-Mobile vs. unlocked from Samsung? I am assuming there are certain bands missing from the unlocked version if you plan on using T-mobile's network, but I can't confirm this....

Best Buy's doing a $100 off if you preorder on Friday just heads up.

It looks like the answer to our question is on this page: https://www.techwalls.com/samsung-galaxy-s9-sm-g960-g965-model-number-differences/
The T-Mobile version seems to be missing the following, in comparison to the unlocked US version:
4G FDD LTE B71 (600 mhz) - This is T-Mobile's new spectrum... this seems important to have (just google t-mobile 600mhz)
2G CDMA and 3G CDMA - I don't believe this matters to us
3G TD-SCDMA B34 and B39 (2010 and 1880mhz) - I assume these will be missed if outside LTE coverage?
But in general, the unlocked version seems to support more bands than the Tmo version
So, it seems if one is on the T-Mobile network and plans to stay there, they really should get the T-Mobile version of the phone.... someone please correct me if I'm wrong.

I'm with AT&T and I'm pretty sure there will be no wifi calling on any phone other than the AT&T version. That's a feature I want. If it doesn't matter to you an unlocked phone may be for you. I don't know for a fact that wifi calling won't work on an unlocked S9 but if it does, it will be the first. I don't want the extra carrier apps but they aren't going to cause me any grief on a beast like this phone. I'd rather have the services the carrier provides if I'm going to use them. If It turns out that wifi calling works on the unlocked S9, I may revise my plan but I doubt that will happen. I'm pretty much done with the rooting/modding stuff so that isn't an issue. Even the master hackers are going with stock phones d/t the features and security.

Question AT&T and International/EU 9 Pro

So, I have been watching the 9 Pro as my next phone (upgrading from HTC U12+), but am really disappointed in a couple of things: (1) it appears there is no plan to certify the US version for AT&T 5G, and (2) no Astral Black for the US.
Since the 5G aspect is unlikely to change anytime soon, and AT&T 5G isn't really all that great anyway from what I hear, is there any downside to buying an EU Astral Black model and using it in the US? I'm still researching all the bands, but it appears the EU model is only missing two LTE bands in use by AT&T (Bands 29 and 30). To be fair, the US version is also missing Band 29 for the 700MHz spectrum, but does contain support for Band 30 at 2300MHz.
I'm going to log which bands are being used where I live and work but, if I will be limited to 4G/LTE anyway, I'm not seeing a downside to buying the EU version. Am I overlooking something? Any thoughts, suggestions, or input is greatly appreciated.

EU has additional options that neither the TMO or US int models have. At&t is behind on 5g deployments anyway so you shouldn't miss out on much, Verizon and TMO would've been better for that. As far as general reqs go, I don't see why not.

I believe that is true - I just want to make sure I'm not inadvertently limiting myself with 4G/LTE coverage by buying the EU version. I don't really care around home/work, as there is usually wifi available. My bigger concern would be coverage in my home area that might get dropped now due to the EU version missing a band that is available on the US version. Or, perhaps when traveling if the EU version is missing bands that other networks (roaming) may use.

You are correct. I call ATT about once a week asking if they're going to certify/whitelist OnePlus devices. I figure the more complaints they get, the more they'll be inclined to investigate it.
To add to this, most people I speak to have never even heard of OnePlus, which makes the conversation troublesome. Be completely prepared for ATT employees to feed you bad information, say your device isn't compatible (does not have the required hardware), is inferior to Samsung/Motorola/iPhone, and try to sell you a new phone or sent you a new SIM card.
I've posted before about calling ATT. I feel everyone who has their service should call on a regular basis. Squeaky wheel gets the grease.

And the strange part is they have the 9 and 9 Pro listed on their list of devices that will still work on their network (VoLTE) after they shutdown their 3G service next year. Gives me hope they will certify at some point.

I run this phone on AT&T, and while I don't get 5G speeds, I get very fast LTE+ speeds of around 200mbps.

Thanks all for the input. After some more thought, I believe I have decided on the pine green US version. It's going to be in a case anyway, and I've had very few cases that aren't black. So, if it will be black anyway due to the case, I might as well get the US version. Plus, I think the black case and green camera bump will look sharp.

Reviving an old thread, rather starting anew:
I want to get the 9 pro for T-mobile use in US. I need dual sims and want custom roms...
I saw that "toolhas4degrees" said they had a Chinese model with EU firmware. I don't know if he changed the firmware himself or what... A bit out of my capabilities.
Simply put: What would I need to do (if anything) to get the EU (LE2123) OnePlus 9 Pro to work with T-mobile?
Thanks!
