[Q]Will unlocked Verizon LG G3 work on T-Mobile?

I have an S5 that I'm about to trade for the LG G3, however, the guy is using it on ATT and claims it's originally from Verizon and is unlocked, hence, why it's working on ATT.
My question is, will this device work on TMobile? I live in Miami, FL if it matters.

I would recommend sell S5 and buy T-Mobile branded G3, or trade for one. You can do either on swappa.com.

If its Verizon branded then it should be unlocked in which case yes any GSM carrier. I'm pretty sure all new Verizon smartphones are global these days.

All LTE Verizon phones released in the last few years are gsm capable and can work on tmob and at. The S5 can also. Just need to switch to global and for data add the correct APN settings

[Q] Stupid Question just need confirmation

I know T-Mobile Iphone 5 and up will work on Verizon as long as it's unlocked.
Why won't my T-mobile unlocked LG -G3 work on Verizon?
Believe me I get the whole CDMA/GSM thing but the fact that that Iphones work through me.
Now I have to sell my unlocked T-Mobile G3 and buy a Verizon One

Tmobile Variant work with ATT all bands?

Hello All-
My Tmobile 6 Edge will be arriving tomorrow- Just curious if I ever decided to switch to ATT would the phone be able to take advantage of all the bands with ATT? Or would I be missing out on a couple?
Thank you for letting me know!

Right now it's unlockable. At least through my efforts.

Buy off-contract from T-Mobile and ask them to unlock it for you. I never had a problem doing that.

Thats what most of us have done. I paid my device in full and they refuse to unlock it until I have been a T-mobile customer for 40 days.
OP - the T-Mobile edge lacks support for LTE bands 29 & 30 which you'll only need in a very heavily populated area. In most situations, the T-mobile edge will work great on AT&T.

Ask a friend who's been a T-Mobile customer for 40+ days to do it for you I did that with my sister's Note 4. Just had to use the phone for a day or two for it to register to the network.

The issue is that T-Mobile doesn't seem to know HOW to Unlock their own phone. At least that's what they're telling me. Supposedly, they may not have the instructions until after the 10th when the phone officially launches.

I unlocked my phone by using the pre-installed app which, after I hit unlock, claimed the device was unlocked and then simply disappeared from my launcher.

So you used a friend's sim card for 2 days? Did you fully just let them use your phone for 2 days? If I can, I'd rather go this is route than wait another 32 days..

I have been a T-Mobile customer for about 3 years now. The point I was trying to make is that I didn't have to call T-Mobile to unlock the phone.

That's the thing. you have had tmobile for a while so unlocking it isnt an issue. that app checks how long your line has been active. i just activated mine to get the phone. sucks. i may end up switching to tmobile anyways. still deciding..

I want to buy a T-mobile s6 off craigslist (for $600 rather than $670+tax from T-mobile or $700 tonight only for an international version), but these posts are getting me scared. I also have no intention of starting up service with T-mobile. If I find a friend (or a seller) who is a loyal T-mobile customer, would I be able to unlock it in a timely fashion? Also, what specifically would the process be?

It will work on AT&T but the T-Mobile variant has fewer bands available.

The T-Mobile variant will have all bands with the exception of 20, 29, and 30.

Any idea if those missing bands are important or not?

I'd can't say that they are not important, but they do not account for the bulk of what you'll generally use. My understanding is they are going to be used in future high traffic areas, but my knowledge is pretty limited.
I can tell you that I have no LTE issues with my T-Mobile Note 4 which pulls generally the same speeds as my AT&T S6 edge side by side.

I'm in a bit of a predicament regarding purchasing my two S6 Edges. I've been on my two S4s for two years and got a Best buy protection plan for them which ends next month. Lucky for me the plan junked out and I'm getting two Bestbuy gift cards for the original value of my phones. The thing that sucks is they don't sell T-Mobile phones, or at least the T-Mobile S6 edge. I was leaning towards getting two At&t versions of the phone and unlocking them. However, I am not sure if features like VoLte(Voice over LTE). If I'm not mistaken LTE should work but I'm not to familiar with the At&t Edges frequency bands and Tmobiles network bands. Any help or suggestions would be greatly appreciated.

See attachments for bands supported by both AT&T and T-Mobile variants. If you're asking if both variant support VoLTE, they do.
The AT&T variant appears to covers all T-Mobile LTE bands but does not seem to cover the 1700 band.
Check threads on previous AT&T Galaxy models on T-Mobile.
I wish I could give you better clarity on using an AT&T device on T-Mobiles network, but I just haven't done it. I've only done it the other way around. I can tell you that I have done this for several generations of Galaxy releases and the results in performance has only been subpar on one occasion. I think that was the Note 2 or Note 3. I don't remember which one right now, but the data was just a little slower at times. This isn't what you're trying to do anyways.
I hope that help a little.

Unlocked TMobile on Verizon?

Sorry if this has been discussed, couldn't find it in search. There are a couple unlocked tmo phones available locally for a bit of a discount, and I'm wondering if there are any significant issues with using one of these phones on Verizon?

I've always used a carrier model, but there's been times I've used Verizon on T-Mobile. They were primarily iPhones.

I have an network unlocked At&t Note 8 that i just configured for VZW using its APN settings and it did not work. The At&t models have the same if not more radio bands than VZW so im not sure what the problem is.

The At&t Note 8 need to have CDMA radio inside in order to work on Verizon.

New galaxy's have a universal modem but will have parts turned off. If the phone is unlocked you can flash the correct modem or the unlocked forward and it should work.

[Q] Best way to get a phone that will work with Verizon and all LTE bands overseas

I've really enjoyed my S7 and want to upgrade to the S9. Later in the year I'll be overseas for almost a year, so I want something that will work with all Verizon bands of LTE, but also not have a firmware lock that would cause it to not work on other bands of LTE overseas. (planning to just use prepaid dataplan sim cards overseas)
I think my two options are to either get a US 'unlocked' version or wait for the 'international' version. My understanding is the primary differences between the unlocked and international version is the 2G/3G coverage for CDMA and possibly slightly different hardware. I'd rather have a phone with CDMA backwards capability, but my prime concern lacking full access to all LTE bands available wherever I am.
I'm not really interested in going any route that would require me to root the phone if there is a way to do it without.

Well the only way to get VZW compatibility is the VZW phone or a US unlocked model. So you're looking at the US Unlocked model at this point.

A listing of all the different model numbers available (per country and carrier) is available here: https://www.techwalls.com/samsung-galaxy-s9-sm-g960-g965-model-number-differences/
You will probably want to get the phone that works with your primary location the most. I am not sure which countries use which frequencies for LTE in Europe; you will need to research that to see what you may be missing out on.
With my T-Mobile S7, I haven't had any issues when traveling in Europe or Asia. It connects to LTE usually.

So I just did a deep dive of that list:
It looks like the Verizon and Unlocked versions are almost identical (the unlocked US version has B46(5200) 4G TDD LTE, but I'm not sure anyone who uses it)
Looking at 4G FDD LTE it looks like a Verizon or US unlocked phone will have almost complete coverage around the world, notable gaps are B30(2300) in China/Canada/US AT&T, B32(1500) in UK and B71(600) (US Tmobile). I thought that was a bit confusing as you'd expect a US Unlocked phone to service all LTE bands available in the US yet it lacks AT&T and Tmobile bands.
So based on all that information looks like I should just get an unlocked US phone to be totally safe, and I'd likely also be fine getting a Verizon version also.

So I'm new to Android but i use Verizon prepaid. Will I lose anything by going with the unlocked version or should i stick with a Verizon S9?
I don't use video calling. All i do is text and talk but I've heard that people on Verizon prepaid have issues with unlocked Android phones.
Thanks

Would Wifi Calling work with the US unlocked on verizon? I thought that required a Verizon FW to be flashed. I imagine all the other features such as voLTE / HD calling, etc to work on the US unlocked.

I did a cursory review of the wifi-calling FAQ on their website. They don't mention anything about compatibility with Unlocked versions of phones (that I saw). I'd call tech support to ask, but I'd expect there to be a 50% chance of getting the wrong answer from the tech based on my interactions with their support.
There might be some good experience based anecdotes in the Galaxy S8 forum, if it works on an unlocked S8 its a safe bet it will work on an unlocked S9
I think I'll ask in the Verizon subreddit, it seems like they normally have really good information as well.
I'm mostly curious about the LTE TDD Band 46 (5200) - its the only band an unlocked US phone has that a Verizon phone doesn't. 5200 is in the U-NII frequency range, no cellphone service providers use it, but I wonder if it may be used for local LTE networks in the near future. The other advantage is avoiding all the verizon bloat wear, but that may be what allows the Wifi Calling to work!

All this has me thinking I might have to add the extra $80 and just buy the Verizon version. I don't get phones on contract and I've always just paid full price. (Page 2 404 error?)

Apparently the Nov/Dec Samsung s8 firmware update added an option for BYOD carrier provisioning for unlocked s8. Given the similarity, I'd imagine the same to be true for s9. Can someone who has an unlocked s8 confirm?

Well after a little more research I see that if you use Verizon prepaid you lose visual voicemail and WiFi calling even if you use a Verizon phone so there's no need in me paying extra for a Verizon S9. Unlocked it is.

You might wanna check this as Verizon is starting to implement network locks on some devices as to deter thefts more
Dont know when or what devices but it was a statement Verizon made

So, you're saying the prepaid SIM might not work in an unlocked S9?
I don't think Verizon is keeping Verizon prepaid SIMS from working in unlocked phones they are just locking their phones like Sprint and AT&T still do.
I had no problems with my unlocked Pixel 2 XL that I purchased from Google and my Verizon prepaid, just no visual voicemail.
