[Q] Verizon GN3 cdma or gsm?

For some reason, I thought the salesman said both Verizon & ATT GN3's were gsm. Is that true or is VZ cdma? I thought I read somewhere they were switching over at some time. I was thinking gsm was preferable, but is it?
Thanks in advance.

The N3 is world phone so yes its gsm too
Sim unlocked ? I don't know the note 2 was unlocked but you can't add APN settings

Thanks very much. So I could use it at some future time on Straight Talk network? What about ATT after contract met? But would an ATT phone transfer to VZ if it's a world phone?

The ATT phones don't have the CDMA hardware to work on Verizon.

All verizon phones have CDMA radios in them. The 3G service from verizon is CDMA. International phones utilize a GSM 3G radio as well, as Europe uses GSM exclusively. The 4G radio, however, is GSM. Therefore, all 4G verizon phones are also GSM. Until 3G gets phased out, All Verizon 4G phones will have both GSM and CDMA radios.

Is Verizon S5 unlocked? Can it be used on T-Mobile?

Hey guys. Is the Verizon S5 CDMA + GSM?
Is it factory unlocked?
Can it be used on T-mobile with everything working correctly (LTE/4G)?
Thanks

I don't know the answer to your question but I can confirm that the Galaxy S5 that I received from TMobile was in fact LOCKED.
I called the support # and was told that I had to have service and use it for 40 days before it could be unlocked.
I PAID THE FULL PRICE ($720 with tax)!!!
I asked to speak with a supervisor -- after 10 minutes on hold -- no change.
I told the store that I was going to bring it back because I didn't pay $700 for a locked phone. Everyone has been nice but it's locked for policy issues and not for technical reasons. I flew to Canada when I bought my iPhone4.
And, AT&T is worse -- one guy told me 3 months and tech support said it had to be active for 6 months.
>> So, my AT&T sim card is not working in my SM-G900T model.

It is GSM/LTE unlocked (as are all Verizon LTE devices), but I'm pretty sure it doesn't have T-Mobile's LTE bands (or at the very least it doesn't have all of their bands).

From what I have been reading, on a Verizon phone, calls and data using GSM and WCDMA bands would work. But LTE bands are Verizon specific hence would not work.
Tl; Dr Voice /data using GSM/WCDMA. No LTE.

Does this mean, once unlocked, T-Mobile and AT&T versions would work on each other's networks including LTE?
I also noticed that with S5, there aren't GSM carrier specific versions. Meaning they are going IPhone route with making all GSM phones enabled that for that country's LTE bands. Is that right reading?

it is unlocked
I am using the verizon s5 on tmobile. It is unlocked and can be used on tmobile LTE. However there are only set modes. LTE/CDMA GSM/UMTS AND GLOBAL. Which means you can't use lte and gsm at the same time (no lte data and voice calls). I usually keep it on gsm, and when I need speedy data I switch it to lte.

How? If you put a TMobile SIM in the phone, or any other foreign SIM, it boots but receives no service. This is in line with almost all other Verizon branded phones (excluding Apple) -- where the phone works (unlocked) outside the US, but won't roam to ATT/TMo in the US.
Pictures please. For the record, my S5 doesn't register on a network with a TMobile or Australian SIM. The Australian SIM in a Nexus 5 roams to TMobile.

This was probably true about a year ago but the recent releases from Verizon, e.g. iPhone 5/5s and galaxy s4 has been fully unlocked world phones. I'm sure there are a few other phones... I think lg g2? I'm not exactly sure. But I have personally stuck my sim(T-Mobile) into my friend's Verizon phones (s4 and iPhone 5s) and they work right away after a reboot. Only problem might be an edit in APN for data and mms. Just sharing my experience, you should check out your phones again.

Not trying to be a jerk, but unless you tried this process in the actual phone in question, then you don't really know if it works. The phone DOES NOT just magically work on TMobile if you put a SIM in, you receive NO service. Now, I didn't go mess around with APNs -- typically those are only for MMS/Data. This is also true for several other phones:
Razr HD / Maxx HD
Galaxy S3
In the past, when the phones were SIM locked, a foreign SIM would prompt for an unlock code before the phone even booted into "normal" Android. That's not the case here -- because the phone is not SIM locked -- but I do believe it is network locked to VZW only when in the US.
For the record, I did try this in my S5. I will be going to Australia next week and will try a Telstra (or perhaps Optus) SIM over there to see what happens.

Yes, I haven't tried it on the s5, but I was pointing out fact that it does work on recent releases which someone confirmed worked on s5 by just plugging it in. I'm also correcting your statement " This is in line with almost all other Verizon branded phones (excluding Apple) -- where the phone works (unlocked) outside the US, but won't roam to ATT/TMo in the US." because Verizon apple does work in the US on T-Mobile and AT&T beginning from iPhone 5. I believe the 4s was still carrier locked.
I was a wireless agent not to long ago, so I know how these things work, not that it magically just works... I'm just sharing you how some recent releases from Verizon has been world unlocked and a few others have mentioned that they just plugged it in and it worked. So good luck and have fun in Australia.

OK Thanks.
It is odd that the apple phones -- and some of the Android phones -- are totally unlocked so that you can use them on ATT/TMobile in the US -- but some (like the S5, apparently) are not. I still am interested to know how some of the other users in this thread got their S5s working on TMobile...

Why would anyone want to buy a Verizon GS5 and use it on T-Mobile? The bootloader is locked and there is currently no unlock method available.

Would you like to exchange?
Would you like to exchange your verizon s5 with my tmobile s5?
i wanted to use it for verizon but the phone is locked to tmobile and at&t.
It would be ideol if i can find someone to exchange it with someone who has a verizon s5 and is looking for tmobile or at&t s5.
thanks,

I can confirm the Verizon GS5 is compatible with T-Mobiles LTE network I'm using one now with LTE all you have to do is go to settings mobile network and switch to Global mode some times you'll have to toggle LTE then back to global to get LTE to kick in.

I am able to successfully use my VZ Galaxy Note 3 and my wife uses her VZ Galaxy S5, both devices on T-mobile Edge, HSPA, HSPA+ (21mbps), and LTE (band 4) frequencies. These devices unfortunately will not do DC-HSPA+ (42mbps), but that's not a big deal for us because LTE coverage is good where we live. We have no issues with making voice calls, or sending SMS/MMS, and don't have to switch APN's or toggle between Global Mode or GSM/UMTS mode. We leave them on Global Mode with the correct APN settings.
Here's the guide I followed for both (with correct APN settings screenshots to accommodate for MMS on page 4 or 5 i believe):

How did you unlock the Verizon S5? BTW theres a bounty on doing so.

This is all new info to me. I have an AT&T galaxy S5 that I want to use on Verizon. Is it possible or do I need to trade for a Verizon-specific model?

[Q] Have Straight Talk and S3 what S5 version should I get (AT&T or T-Mobile)

My S3 is an AT&T version.
Thanks.

Thanks. I had read some message traffic that says AT&T version would be able to fully use 4G/LTE networks while T-mobile is limited to HPSA+? Originally I thought those were two different names for the same thing (AT&T calls LTE, HPSA+) but apparently they are different. Doesn't LTE provide better speeds than HPSA+?
Also for my S3, I have a Straight Talk AT&T SIM. Do I need a different SIM for Straight Talk using the T-mobile version of the S5?

T-Mobile does provide LTE speeds as well but straight talk's T-Mobile is only 3G so your best bet is to get the T-Mobile S5 and unlock it and use straight talk's AT&T Sim card you currently have (given that it's a micro Sim card)

If i have a tmo s5 that i want to use with straight talks at&t sim do i need to buy the unlock code or can i just flash an international Rom?
And either way would i get full LTE?

[Q] Switching Carriers & Unlocking Download Booster

i am currently on Sprint and have had it with their service. I live near Chicago, supposedly one of Sprint's maiden Spark cities, and their speeds have either stayed the same or have been worse than in the past. Because I just bought my phone under contract and other reasons, I am looking to jump to T-Mobile.
One thing I am considering is whether or not I should keep my current S5 or trade it into T-Mobile and get a new S5 from them. I know T-Mobile has the Download Booster feature unlocked on their handsets, but I am not sure if this is something deleted from Sprint's handsets before they sold them, or if the device is locked by the SIM or any other reason.
Has anyone else had an experience making this switch? I am curious what others have experienced.

u can not use Sprint S5 on T-Mobile anyway, time for new S5 if u made that switch.

In the past, that is true. The S5 actually uses a SIM card and can be used on a GSM carrier.

lookup Sprint S5 (CDMA) and T-Mobile S5 (GSM) then u will know what is the different.

I am fully aware the difference between Sprint's CDMA network and T-Mobile's GSM network. If you look at Sprint's S5 specs, it still has a GSM antenna. Here's my reference.

Can I use a Tmobile Note 4 on AT&T and vice versa?

Can I use a Tmobile Note 4 on AT&T and vice versa and have it work with LTE?
In other words, is the Note 4 interchangeable with both Tmobile and AT&T LTE service?

Potentially, yes. You could do the reverse, so I can't see why it wouldn't work.

It's showing the same bands to it should work, no one will know until they actually test it. The Note 3 also had the same bands, but some anecdotal reports stated the reception was a bit worse and it didn't hang onto LTE as well. Nothing scientific, just users reporting this so make of it what you will. Personally my business can't take the chance of reception issues so I just bit the bullet and got the ATT version knowing I am saying goodbye to root. Once again this is unsubstantiated, it's just what I got from hours of looking at all the forum posts about using the Tmo Note 3 on ATT.

How about a Verizon Note 4 on AT&T? Verizon is charging almost $150 less for an off contract phone, however I have a mobile share plan with other AT&T phones on contract so I'd need to stay on AT&T if possible...

Is it possible to "unlock" (or whatever the term is) an AT&T phone to use with Tmobile?
I want to use AT&T mainly but when I'm traveling internationally, I want to be able to switch to Tmobile.

Yes you can and the term is "unlock". Just make sure the bands are compatible on your at&t phone with the Tmobile network.

I know you can use TMOBILE PHONES on ATT - I assume you can do the reverse -but I don't think you can run TMOBILE PHONES on Verizon - or Verizon PHones on TMOBILE - I say this because the roms created for Verizon were really never very compatible for Tmobile phones ( at least not for me on any of the roms I tried to flash - data didn't work - wifi didn't work - ) so I htink they have different kinds of radios - but I am not a developer so that is only a guess -
USE TMOBILE phone on ATT and you are fine

Yes - as long as you manually add the APNS - but keep in mind the ATT PHONE will have a locked bootloader and it will probably be a while until someone finds a way to root the ATT PHONE - I say this based on what happened with the Note3 and S5 - I assume the same will be the case for ATT NOte 4s

If somebody takes an AT&T phone to T-Mobile, it will get fully functional LTE (as they both use band 4 aws). However, T-Mobile has built most of its 3G network on Band 4 UMTS / HSPA (AWS 1700/2100) which AT&T phones to not support. This coverage footprint is bigger than their current LTE network. The AT&T phone will get Band 2 (1900) UMTS / HSPA in the areas T-Mobile has refarmed.
A T-Mobile phone is fully compatible with AT&T. All T-Mobile phones support bands 2 and 5 for 3G (H+). T-Mobile phones also support AT&T's Band 17 for roaming reasons.
Be advised that if your using a T-Mobile device on AT&T (preferably an LTE device) it may not get the best reception, as AT&T optimizes their modems for their lower frequencies. Last year my T-Mobile Note 3 LTE reception was awful on AT&T. The T-Mobile S5 on AT&T was improved, but not as good as AT&T's own S5's reception.

I'm not sure. But a few years ago there was a guy from Canada using a Rogers device ( I think the S3?) anyway AT&T had just released an update for their S3 and it drastically improved signal strength and data speeds. He took it upon himself to flash only the modem from CWM. The phone rebooted and he had no IMEI number. Therefore his phone couldn't even connect to the network. I'm not sure how or if he resolved it. But that lesson right there made me never flash any carrier's modem on my device.

That would keep me away too - but it's too bad - as much a like as the variants are - it is too bad they are not more interchangeable
