900a vs 900t questions straightalk - Galaxy S 5 Q&A, Help & Troubleshooting

I have straight talk... curious major differences between AT&T vs T-Mobile
also if I went with T-Mobile on straight talk how would I use it on AT&T and would 4G LTE ect or how would it go?
I know I would need to have both AT&T and T-Mobile APN's to switch around on?
Simply put if I got a T-Mobile I can still run all bands on AT&T straight talk but benifit switching APN from AT&T to T-Mobile as well?
Thanks

Since this was never answered, let me try to help you. A T-Mobile S5 runs just fine on AT&T as long as it's SIM Unlocked. I use a 900T on AT&T (for customization purposes) with no issues. All you need to do is add in an APN for AT&T, which can be found with a Google search. With Straight Talk, I'd imagine you'd need to use their AT&T compatible APN. Since you're discussing service through them, I doubt your Straight Talk SIM would register with T-Mobile or AT&T APN's. However, I could be wrong. I've never used an MVNO and I'm not quite sure how a sub-network SIM card would act on a parent network.

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)

I'm a straight talk user living in the USA. For me to continue using straight talk what phone do you recommend? Should I get the AT&T or T-Mobile version of the S5?
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] T-Mobile LG G2 on AT&T

Hey I was wondering if I unlocked my LG G2 from T-Mobile would I be able to use it on AT&T's network? I would like to still get 4G LTE but I'm not sure thats possible. I asked a AT&T representative and they said that I would get AT&T's 4G LTE after registering my IMEI and with the correct APN settings. Can anyone confirm this? Thank you very much for any responses.
I used an AT&T SIM and the Go Phone $60 plan on my unlocked D801 for trip to Alaska in May and got LTE in many places. Use "phone" as the APN.

Oh okay thanks. For some reason I heard that a lot of people didn't get good data speeds or something like that. Maybe those people didn't fix the APN or the IMEI
Bump?

Unlocked HTC 10 Converted To VZW with Verizon MVNO's

Hello everyone,
For those who have converted their unlocked HTC 10 to Verizon, I need someone to test a Verizon MVNO Such as Straight talk, Total Wireless, Red Pocket, Page Plus, etc. Need to know if any Verizon MVNO works on unlocked model before I buy this phone. Dying to buy this phone, but this is holding me back.

This is obvious, not looking for GSM Based MVNO feedback,
Let me re-phrase the question:
VERIZON CDMA MVNO'S ONLY and someone that can actually confirm that a verzion mvno is working in their converted unlocked HTC 10
I have my S-off unlocked, unlocked 10 with the Verizon radio flashed to it on Verizon prepaid which if you can use it on Verizon prepaid then you can use it on any Verizon mvno. But as they listed for post paid you need to activate your sim in another phone then put that sim in your unlocked 10. Mine was previously used by my unlocked Motorola nexus 6 and with my unlocked 10 on my Verizon prepaid account when I log in to my Verizon it still shows my device as a non Verizon nexus 6, but my unlocked HTC 10 works just fine. Just realize volte will not work because prepaid Verizon mvnos do not get to use volte as of yet. Also I had to turn my WiFi calling off as it would not work. I am running viper10 1.2.1 and it works great. They just got android pay working too.

Error on HTC's part. There are 4 "variants" of Straight Talk, each runs on one of the big carriers. Straight Talk AT&T and Straight Talk T-Mobile can use the unlocked version out of the box. Straight Talk Verizon will have to do the same thing Verizon-proper customers have to do to use the unlocked model (flash VZW modem, use an already-activated SIM, etc). Straight Talk Sprint won't be able to use the unlocked model due to it lacking the Sprint LTE bands and most likely not being on Sprint's device whitelist.

International version Note FE f/ds and AT&T issues

I've looked through all of the threads trying to find AT&T settings for the universal model but only come up with a few T-Mobile threads. Having a tough time forcing LTE on AT&T. (prepaid vs. Postpaid if that helps) AT&T store reps were Clueless and I've tried every APN setting known to man it seems. Anyone have their service working well using this model on AT&T and do you recall what you had to do to get it working normally? Thanks in advance.
