[Q] Switching Carriers & Unlocking Download Booster - Galaxy S 5 Q&A, Help & Troubleshooting

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.

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.

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.

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):

Unlock S5 From Sprint To Tmobile?

I recently got the S5 on sprint and im beyond disappointed with sprints new spark and lte network out here in NY. Im considering going to Tmobile since there lte speeds are crazy good and connection is steady out here. My question is can i get my phone unlocked and bring my sprint version phone over to Tmobile? I was told by a Tmobile rep that my phone would go down to 2g speeds and its not guaranteed to even get lte. Which i find hard to believe since since my phone has the option to also go on GSM/UMTS. Whats your guys thoughts on this?

Correct. Sprint uses different frequency ranges, so unlocked or not it's just not going to communicate.
ATT and T-Mobile work due to the overlap. In fact, for a while there ATT was going to purchase T-Mobile before the FCC put a halt to that.
Glad too as T-Mobile is now shaking up the market and forcing (encouraging?) Verzion and ATT to try and adopt similar measures in order to maintain customer base.

I dont think this is correct. Albeit S5 is a different phone, but I unlocked 4 SPH-L720 S4's from Sprint to Tmobile no problem using the following thread: http://forum.xda-developers.com/showthread.php?t=2530610
If S5 could use the same methods, you would get 3G and HSPA+ on the Sprint S5 using a TMobile SIM.
I was able to get LTE using a TMobile SIM on a Sprint S4 by using DFS to edit the NV to enable AWS 1700 LTE Band in NV items, then flashing the TMobile HOS and MODEM bin files - along with copying the *ril*.so libraries to the system/lib directory. This ultimately allowed me to select the LTE/WCDMA/GSM option in Mobile Networks.
Not many people know about this but I found it in an i337 thread on how to unlock AWS on a S4.

Has anyone comfermed this? To my knowledge the Sprint/Verizon phones are not cross compatable with AT&T and T-mobile. Some verizon phones are the exception but basicily its a no go from CDMA phone to GSM tech.
confirm
i can confirm the sprint s4 does work on tmobile with a bit of editing and following the gsm domestic tutorial on xda, however this part about the modem.bin and hlos isnt confirmed and i have done this and ended up hard bricking my devices and had to jtag to repair them. ive tried many times and always bricked so i say no go.
this forum is for the sprint s5 and i would hope we can find a loophole to get it gsm unlocked. any ideas? ive tried a few things but no luck
Theres alot of incorrect information here. The latest Sprint phones using sim cards ARE ABLE to use T-Mobile and AT&T as long as GSM is in the hardware. I dont own the S5 but for those blinding others with frequency talk I'm tired of seeing, read it and weep:
http://www.phonescoop.com/phones/phone.php?p=4408
Sprint S5 supports GSM. Now of course no LTE on T-Mobile due to the lack of the 1700 frequency,
but your 4G will be fine. Depending on where you live, you may not even care about LTE over 4G.
Sure, Sprint locks the darn thing up to avoid it getting into the hands of other domestic carriers, but
just as the Sprint Note 3 and my Sprint LG G2, a workaround has been invented. For the G2 it was as
"borrowing" the stock T-Mobile LG G2 firmware and tweaking it to boot up on our LS980. We have
about 3 different tastes of working unlocked roms, not only sticking to T-Mobile, but other carriers
reported working such as Metro PCS and AT&T. So my guess is that the S5 may need a similar
treatment, nobody wants Sprint honestly. The first 14 days (brought in my own LG Optimus G LS970)
I was with them service was glorious here in NYC. But after the 14 day "trial period" ended I was
DAMNED into horrible service, constant 3G instead of 4G, etc. Thanks to refusing to make payments
due to the disgusting service, my GS4's IMEI is basically crap, so I sold it in the same week I got it.
I should have never swapped it out for the LG OG...
Honestly, I'll thank every OP I see that "unlocks" the Sprint version of any phone for domestic GSM
use. Their silly Sprint Spark is useless, why introduce something new when they dont even have full
4G coverage here in the USA? And their agents sound like "AI" controlled cyborgs: "Oh we're sorry to
hear that, your zone is scheduled to be recieving 4G soon." Yeah right. I feel sorry for those who suffer
in other states.
ANYWAYS sorry for drifting off topic. The recap here is that the Sprint S5 IS capable of domestic GSM with some modding.
And also that I hate Sprint.
Any Updates on this
Does anyone have any news on this? I have a S5 from sprint and want to use it with tmobile or other gsm carrier. any1 have any updates on the UCCI deal i read about somewhere? I have the spc phone is rooted what do i need to do? cant bring up the service menu to change things there.. kind a lost pls help
..
lease has anyone found a solution for enabling aws bands on galaxy s5? i have the at&t active version unlocked and rooted using on tmobile but i get only edge :/
What is the verdict? Is there anyone who knows you can use it on any network? I am getting mine tomorrow and am unlocking it. Is there a way to test if they will work on any network? I have many sim cards from diff carriers.

There have been a lot of threads about this, so clearly few are even bothering to search the forum for existing threads and the wealth of information in them.
Sprint is a CDMA system like Verizon & USC. CDMA per se is incompatible with GSM, which is what most of the world uses. The Sprint S5 only supports some of the most common GSM frequency bands and moreover will have a locked bootloader and SIM.
Sprint will not unlock the SIM (actually SPC code) to allow using it with other domestic carriers. You can find third party vendors that will "SPC unlock" your Sprint phone. But then you will find that Sprint's S5 won't support any of the LTE bands on other CDMA or GSM carriers and misses some GSM bands too.
Nor can you use custom ROMs, kernels or recoveries in the normal manner due to the locked bootloader. You could probably use the Verizon Safestrap method to emulate a limited palette of custom ROMs, but you would have to do your due dilligence there and look into the details.
In short, if you jump through enough hoops, you can use a Sprint S5 on another carrier like TMobile. But it will always be marginal. You won't get LTE data speeds, you will see more congestion than those using native handsets, due to your reduced number of bands. And you may have no coverage at all in some fringe areas served by a TMB band that your handset doesn't have.

The limitation of what "bands" the radio will cover are software defined. if you look around. you can find a way to modify those defined rules.
to allow it to use 1700 LTE. although the legality may be questionable as the FCC approval for that model was not tested with the LTE. The baseband chip/radio still supports the band with the software changes

What in the heck? Who fed you this bologna? Do you work for Sprint? Cause I have various complaints for you if you do. My SPRINT G2 running a T-Mobile G2 stock rom which is unlocked DOMESTICALLY works perfectly fine with T-Mobile's 4G. I don't think many people care about LTE, getting off of Sprint alone is a huge leap for mankind (in this case G900P owners). And as it was mentioned, there are ways to get that nice LTE band for various devices with simple mods, problem is that it is NOT widely recognized yet and very few people know that the possibility exists because of various misleading posts that "its all in the hardware" and fingers being pointed at Qualcomm's techniques. Yes there is a possibility for a domestic unlock, sure there might not be LTE for it, but most people will be content with the fact that they can use their expensive locked down phone with another carrier. Honesty Sprint devices would be better off being sold for less than carriers that actually DO allow domestic unlocks. Why do we pay over half a "K" for a phone that in reality we do not completely have full rights over? Why do other carriers alow domestic unlocks and Sprint wants to be greedy and lock in all of their customers with shady contracts and decieving bills?
Thats why many of us including myself would be beyond grateful if we even get some 3G with another carrier. We have CDMA capabilities, we have GSM capabilities, all we need is some sort of domestic unlock.
There is NO third party unlock code of any sorts that will unlock a phone that is unlocked OTA. Check around for many posts from various foreign users who have gotten stuck with a useless Galaxy S5 that can only be used with wifi thanks to Sprint. Is it their fault? No. It is purely Sprint's fault for being so damn greedy. Thankfully I am hearing news that by February of 2015 all devices will be GSM and have the capabilities to be unlocked for domestic use.
Custom roms, honestly most of us are just unsatisfied with the average and like to go to the unique side. But is Cyanogenmod going to allow us to use Air Gestures and all the other cool features of the S5? Not really. Custom kernels would be nice, but many people only seek then in order to overclock their device, which this device is in particular really doesn't need any more added power (or battery drain) than it already has. Optimization tweaks might be worth it but I dont see it helping. If someone could fix the delayed multitasking transitions (switching from one app to the other at times is delayed a second or two) or the crashing browser without custom roms or kernels, then it is best not to waste time on the development of such things. But then again there are those who prefer stock android in combination with other features such as the AMOLED screen technology, but it is best to look for another device.

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?

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.

Well, that's what I want to know. Will LTE work on both networks with either or both Tmobile and at&t versions?

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...

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

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 - 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 am pretty sure I know the answer to this - but if the ATT modem is better for att users - if someone does have a TOMBILE PHONE - why is that we can't flash an ATT Modem on the TOMBILE Phone?
I realize there is a chance of 'brcking" but if the phones are so close to each other anyway - why can't you flash an ATT Modem on a TMOBILE phone? Anyone?.

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

T-Mobile S5 on Verizon network... Is it possible?

I've been with T-Mobile for many years and am currently using a rooted S5. Recently moved to a rural area where the only good cell signal is Verizon, so thinking of switching. Is it still true that GSM and CDMA phones are not at all compatible on each other's networks, or is this possible? My S5 is all paid off and working fine, so I'd hate to have to start over with paying for a new device since Verizon has now gone to the same "non-subsidized" equipment model as TMO.
It doesn't look like it's possible. https://community.verizonwireless.com/thread/822033?forceNoRedirect=true

Sprint best GS 7 to buy for most carrier support?

I am leaving post paid service and going pre paid.
I since majority if prepaid US carriers are Sprint, T-Mobile and some AT&T. I want a GS 7 that will support all three carriers with as much bands possible.
Any suggestions or does the Sprint version support (once unlocked) support AT&T and T-Mobile.
Technically, any GSM unlocked phone would work on any GSM network, but that wasn't your question.
I ordered the sprint version to use with cricket (at&t network). What I read, the sprint version will support AT&T better than tmobile. In the end, once rooted, you could add in the band's not supported by default.
Music to my ears!
Will have to get the Sprint version and hope for the best.
S7E's sprint version can't turn off shutter camera. But im still happy with the 50%off promo
Has it been confirmed that the s7 uses sprints LTE advanced signal. I can't find a place where it says for sure like the g5's page .

I'd like to know this as well. I seem to get better 4G coverage in my area with the advanced signal enabled compared to my friends who don't support it.
Yes, my new s7 uses lte adavanced
Splash screen says so

Sweet. I have the nexus 6 now and considering getting one for the SD card access alone. Is there a noticeable difference in data speeds with the LTE advanced, does it offer data and voice at the same time?

It just seems that way, or it's because it has a better antenna in general. LTE Plus doesn't get you a stronger signal. The beamforming that helps at the cell edge is a tower-side enhancement. As long as your phone supports band 41, you're able to take advantage of LTE Plus - just not the Carrier Aggregation component.
I am very eager to see what happens in this regard as well. Sprint is notorious about locking down their phones to include very few LTE modes so that the phone is truly only for Sprint. Samsung's CDMA version of the Galaxy phones have been crippled in this way all the way up to the S6.
You can see various phones like the S4, S6, LG G4 and the S7. The S7 CMDA variant does not appear on this comparison chart yet but I'm hoping that it won't need to.
http://www.phonescoop.com/phones/compare.php?p=4066,4769,4773,5081,4928
The last phone in that comparison is the iPhone 6s Plus, which is the same no matter which carrier you use worldwide. I really, really hope Samsung does the same thing.
The only other phones with lots of LTE bands like the iPhone on Sprint is the Nexus 5s/6p and Moto X Pure.
PLEASE let LG and Samsung include all the default LTE modes by default on the CDMA versions of their phones!
Edit: nope, Sprint made Samsung get rid of the most important worldwide LTE band, 7, along with 13 and 20. LAME.

I'm thinking of buying the SM-G730P (Sprint) version of the Galaxy S7 even though I was all the years on Verizon and they are for sure the better service and have more coverage, at least here where I live, but the reason I wanna buy Sprint is just because Verizon just makes Samsung phones much more secure, and locks the boot loader, now the question is, First of all does Sprint still lock their LTE phones? And second of all, will an unlocked Sprint phone work on the Verizon network, and will it work overall perfectly when I'm aboard, on the International GSM network? And last of all is there a different in the build of this 2 phones, Verizon S7 and the Sprint S7, besides the bands

Today's news concludes that all US (Qualcomm) variants of the S7 indeed have a locked bootloader except for a select few apparently. Verizon and AT&T lock the bootloader tighter than others, such as Sprint. Sprint and T-Mobile didn't lock the bootloader themselves but rather Samsung. Samsung locked the bootloader to better add security to their consumers and there's been hints they may release an unlock kit/tool for developers but this hasn't been confirmed.
I got Sprint to unlock my G930P and works perfectly with AT&T. The S7, at a hardware level, is the same phone for all US variants where the only thing that changes is the software. Meaning a Sprint phone on the Verizon network would essentially have the same network performance as if you were to use an actual Verizon variant. Once the device is unlocked, at least for me, it knew my sim was on the AT&T network and switched the bands to AT&T on reboot.
Internationally, I'm not sure. There is an option to enable Global bands in one of the hidden menus in self-service but I'd assume it'll cover enough bands to provide you with what you need minimally. (I've never gone international before so can't say from experience)

GSM will work as expected.
LTE, however, will be crippled depending on the country you go to.
The updated spec list:
http://www.phonescoop.com/phones/phone.php?p=5081
According to that list, Sprint purposely took out three very important LTE bands: 7/13/20. Why does that matter? Because much of the world uses these three bands, especially band 7 and especially Europe! Sprint purposely crippled the LTE radio modes for this phone and I cannot understand why.
So yes, you'll probably get normal GSM and some LTE if they offer one of the other bands but Sprint purposely disabling or deleting the commonly used international LTE modes abroad is just anti-competitive and backwards.
Will rooting or unlocking this phone allow the use of the bands that were locked by Sprint?

The splash screen says LTE Plus, not LTE Advanced. LTE Plus is simply the new branding for Sprint SPARK. Was that the OPs question?
LTE Plus is not Sprint Spark , its more in depth. Carrier aggregation by antenna beam forming.
For those interested, Sprint is releasing an unlocked S7 that works on all the carriers and has a full range of US LTE bands:
