[Q] Groupon S5 Deal: Work on T-Mobile? - T-Mobile Samsung Galaxy S 5

Groupon has a deal for the S5 that says it's for "Verizon and GSM Unlocked":
https://www.groupon.com/deals/gg-samsung-galaxy-s5-smartphones
Is there any way to tell what model # this is? I'm guessing that it is a generic S5 and not the T-Mobile specific SM-G900T. If that's true, then it likely doesn't have the TMo specific LTE frequencies needed for full service (I'm in the Chicago area), correct?
I really hate having to find special versions of GSM devices to make full use of T-Mobile's network...

<TAP><TAP> Is this thing on???

Unlocked for all Verizon and GSM carriers.
On the same page --> https://www.groupon.com/pages/groupon-deal-images-gg-gsm-providers
Only thing is that it probably will not be compatible with WiFi calling features, but I could be wrong.

I know it would work but I was curious about whether it was the same model they sell via T-Mobile that has their unique frequency bands (1900/2100 I believe). Groupon responded to an inquiry and said it was a Verizon model so while I can't confirm it, I'm guessing it doesn't have the extra bands needed to fully make use of T-Mobile's LTE network so it would likely drop down to HPDPA+ in many locations.

According to the reviews, its a Verizon branded phone. A couple of the reviews are from T-mo users and they claimed to have issues with the sim/network not going to LTE, instead it uses their HSPA network.
If it was me, I would not buy this. It is cheap yea, but remember that the S5 is not compatible with the new band 12.
-edit-
The Chicago area isn't getting band 12 anyways, not anytime soon that is.

I'm using a Verizon S5 with a T-mobile rom and it works perfect 4g lte and all If you end up getting it just root it then look at my view forum posts.

Is the VZW Galaxy S4 SIM and APN unlocked out of the box?

Hey everyone,
I just searched this topic and didn't find any definitive answers so I thought I'd ask...
Anyways is the VZW Galaxy S4 SIM unlocked out of the box? I keep reading the new VZW releases in 2012 and onwards are according to the VZW forums and website but then I found a post of someone asking VZW for an unlock. It its an official code its easier to just ask VZW as I meet all the requirements (1+ year customer). Also I read that on the S3 the APN settings are blocked on the default VZW firmware unless rooted. Is the APN settings on the S4 open (changeable) by default?
Also what's a realistic battery life you guys are getting out of this phone?
Am comparing phones and need a phone that is:
1. SIM Unlocked and APN settings changable that has VZW's US CDMA and LTE bands PLUS ALL the international bands (the 4 GSM and 4 UMTS international bands).
2. Has HSPA+21 at least.
3. Long battery life to last the day.
4. Rootable so I can get rid of VZW crap and increase the battery life.
I've also not seen any international VZW phones with HSPA+42 dual carrier like Apple's iPhone 5. I'm also debating getting a Android versus iOS phone...

Recently took my S4 to Brazil and spent a fair bit of time talking to Verizon Global Support before the trip. One of the questions I asked was whether the phone was SIM unlocked so that I could purchase a SIM card while in Brazil and use local service down there. The VZW rep assured me the phone was indeed unlocked, but I did not use a Brazilian SIM card while on travel so I cannot confirm via personal experience.
I can confirm that it is unlocked. I put an active att sim card in, that then allowed me to add the correct apn info. I was then able to make calls and use data.

The SCH-I545 has Quad band GSM/EDGE frequency's (850/900/1800/1900) and Quad band UMTS/HSPA (850/900/1900/2100) As well as AWS bands for LTE (1700/2100) so it should get LTE on T-Mobile. However, it does not have the capabilities to get LTE on AT&T since the SCH-I545 does not have the frequency's to operate on AT&T's LTE network but it will get HSPA+ on both networks. It will work on Sprint as well but it will not get LTE since its two LTE bands, (700 and 1700/2100), are not compatible. Sprint operates on the same CDMA/ Ev-Do bands as VZW so you will get 3G. I can confirm that i have used the SCH-I545 with an AT&T SIM card and i got HSPA+ speeds.

The AWS is there but not activated yet. for now you will only get EDGE on t-mobile unless in a refarmed are you will pickup HSPA. you will however pickup all AWS tis summer when verizon activates that band on our phone.
SOURCE: I'm on the 30$ a month prepaid with t-mobile. edge sucks but it works.

Hi,
I have had the same outcome, voice and data work, BUT data is only HPSA+ at best. Do you get 4G LTE or found a way to get it?
Thanks!

No, but that is because i am not in an area where ATT has LTE turned on. South Dakota is still on the waiting list. Verizon uses different frequencies for LTE then ATT does.
Verizon has never locked their phones, even the CDMA ones. If you put a non Verizon SIM in you can change the APN settings

Universal phone? Verizon and T-mobile?

Hi, im looking for a phone which would work with both verizon and T-mobile. Why both? well im in an odd situation, where im halfway through my contract with verizon, but want to switch to T-mobile. But my phone right now barely even works at the moment, so i need a new one, which I can bring over with me when i switch to T-mobile
I need a phone which works on both carriers or else I will end up buying to phones at full price, and I wouldnt want to do that!. Any help wpuld be extremely appreciated, there has to be some kind of smartphone out there thats capable of this

A lot of phones these days are tri/quad-band. This means they operate on 3 or 4 frequencies ranges.
I'm not from the US so I'm not 100% sure but I believe Verizon is a CDMA based network while T-Mobile uses GSM (or WCDMA).
This would mean that most phones cannot be taken from one to the other. However many newer phones are released in carrier specific versions but don't have any hardware differences. Its often very hard to test/confirm this without having the specific device in your hand.
Google suggests that the iPhone 5, 5C & 5S from Verizon is unlocked and works on T-Mobiles 3G & 4G networks. So this could be an option.
As far as android handsets go, most of the phones I can find dont have a good overlap of frequencies for both networks.
Using the LG G2 as an example, the T-Mobile versions of most handsets use 850/1700/1900/2100 for 3G and LTE Bands 2, 4, 17. Verizon uses 850/900/1900/2100 for 3G and LTE Bands 4, 13. There is a little overlap there, 3G @ 850, 900 & 2100, but the LTE coverage is limited to Band 4 which could result in some negative experiences coverage wise on T-Mobile.

Unlocked Gear S on any cellular carrier network? ATT version compatible with T Mob ?

I saw a couple of tech points in the other threads. I myself have purchased the Att variant and planning to set it up with T Mobile but as I said, someone pointed out that they have different cellular banding or something to that effect. This person went on to say even if we were to get the ATT Gear S version on T Mobile that speeds would probably only be 2G.
From the articles that I've read on the Gear S specs I haven't come across anything saying that Samsung has designed specific versions for each U.S. carrier.
I do not have the answer at this time whether or not full cross compatibility is built into the device or not. Purely going by what has been announced, again I do not think it has been modified to keep us from doing carrier jumps.
I will update when Tmobile gets their networks up and running for the Gear S. If anyone can clear this up with for sure information, please do so. Feel free to speculate but if you're not certain please say so. Thanks.
If I can't get full functionality on the TMobile network with my ATT purchased and unlocked Gear S, I guess I'll have to return it and pony up the extra $50 that TMobile charges and fully join that club. Guys it may not be worth the hassle. I'll have an update soon on how all this works out, however I'd like to welcome feedback on the issue.

Im doing the same thing tomorrow.
You can go to Samsung.com to check out the official spec. There are 5 different carrier variants but only three listed so far: AT&T (SM-R750A), Verizon (SM-R750V) and Sprint (SM-R750P). The missing two are T-Mobile (SM-R750T) and US Cellular.
Each listed different supported network (CMDA vs GSM) and bands.
It has the Snapdragon 400 which supports a HUGE number of bands and supports a global mode for both CDMA and GSM.
https://www.qualcomm.com/products/snapdragon/processors/400
https://www.qualcomm.com/products/snapdragon/wearables/samsung-gear-s
Someone will figure out a way to get the device to work with them back and forth ... it may be through a rom or a command line. But if you aren't a tinkerer you'll probably want to go with the version of the watch for your preferred carrier.
Update: I did a search through the FCC and didn't see one with T-Mobile specific bands (1700/2100). Bad news though is that there definitely are two variants for CDMA AND GSM. Argh. I stand brutally corrected!

Will this work? Verizon M8 --> AT&T fo-'official'?

I have an old M8 lying around that I fired up and had remembered I had rooted it and the bootloader is unlocked.. Is there a way to 'trick' this phone into thinking it's an AT&T branded phone? hboot, etc. and that will allow me to RUU something official from AT&T? I know this sounds really strange and probably stupid but.. I just can't sleep and need something to fill the time.. Can I do it?
Don't think so, radio hardware is different, not to mention the partition layout.

Absolutely not. At least not any way that is known; and your chance of failure is high (with a brick being the possible or even probable result).
As mentioned in the previous comment, the partitioning on the phones is different. If you try to run the RUU, you at best it will fail, at worst it will brick the device.
Most other M8 versions (that don't support CDMA) can be "converted" from one version to another (other exceptions being dual SIM and M8 Eye). But Verizon and Sprint are the oddballs here. Some experienced devs have been messing around with these variants from the start (to try to convert them) with no success.
Perfect! All I needed to hear! Ah well.. it was worth a shot! Just trying to get my account provisioned for LTE so I can get LTE on my unlocked devices.. I've been told, and read, that if I can get an AT&T branded LTE capable phone to just swap my SIM in it.. and let my account provision, then I'll have LTE on any device AT&T or not... Just trying to avoid a contract..

As long as the phone is SIM unlocked (Verizon version is) then you should just be able to put an AT&T SIM in, and enter the proper AT&T APN for service, as long as the phone supports the proper bands. Its irrelevant whether the phone is AT&T branded or not.
Now the underlined bit in the paragraph above is the main issue. The Verizon M8 only supports one of the four bands (Bands 2, 5, 4, and 17) used by AT&T for LTE (Verizon M8 supports Bands 3, 4, 7, and 13). So depending on what band is used in your area, you may or may not get LTE.
But GSM (2G) and HSPA (3G) should work just fine on AT&T.

That's the odd part.. My main phone is the S6 Edge from Verizon.. it's on the AT&T network and I assume my APN is correct.. But it's not picking up LTE and I am almost certain the S6 Edge from Verizon will pick up the correct band for AT&T LTE .. But it's only using the H+ speed.. What's even more strange?? When I throw my SIM into the M8? I get LTE on AT&T and verify with 30+mpbs speeds.. I have no idea what's going on...

Yeah, that is strange. According to the specs for the S6 Edge here, the Verizon version supports the same LTE bands as the VZN M8, and actually some additional bands (2 and 5) that also happen to be bands used by AT&T.
One thing I can think of, is that the VZN M8 in actuality supports some bands that are not advertised/explicit in the specs. It wouldn't be unheard of, as members here have reported some versions of the non-CDMA M8 as supporting some bands not indicated in the specs. And that band happens to be what AT&T is using in your market region. In this case, that band would seem to be Band 17 (the only band that AT&T is known to use, that isn't listed on the S6 Edge specs).
Or the other possibility, is there is just some issue with the S6 that is preventing connection to LTE (but on the same supported band that the M8 has).

Yeah.. I'm not worried about it.. I've been told that all I need is an AT&T branded LTE capable device hooked up to the account and that my account hasn't been provisioned for LTE .. I've seen this in a few places so it's worth a shot.. I ordered a junk LTE phone branded AT&T to test it out.. ordered a OnePlus 2 and will likely unload the S6 Edge (if it never picks up the LTE from AT&T)

As I've already mentioned, its not really necessary to have an AT&T branded device. I suspect the reason you've seen people say this, is that AT&T branding means by definition the phone has all the bands used by AT&T for LTE; since obviously the phone is intended for use on AT&T's network. Since AT&T uses a number of bands (4) and LTE bands being used worldwide has become very un-standardized, its somewhat difficult to find a non-AT&T phone that has all the bands. But they do exist, such as the US unlocked M8, Dev Edition M8, and Nexus devices. Also, I've seen folks used other non-ATT branded phones, which may not have all 4 LTE bands used by AT&T, but the one(s) needed in the particular user's region. Not ideal, but sufficient for some folks.
Another reason why some may say the phone needs to be AT&T branded, is that AT&T tech support won't provide you any support if you have a non-ATT phone. But honestly, I've used non-branded devices (and plenty of folks here have), and this is very rarely an issue. The folks here on XDA will usually provide you better support, anyway!
Of course, your ATT account needs to be provisioned for LTE in order to have that service. Its a simple matter, and doesn't cost anything (just need a smartphone data plan).

Absolutely NO.
What I mentioned above (Post #3) for the Verizon variant, also applies to Sprint (both versions support CDMA - the fact you don't use it is irrelevant). If you try to convert to another version won't work, and will probably result in a brick.
Also, even if you didn't have a CDMA version M8, you typically can't convert using an OTA, it has to be an RUU.

Absolutely NOT. As already thoroughly discussed on this thread, if you attempt to install another version's radio on the Verizon version, it won't work, and you may radio brick the phone (permanent damage possible).
Different radios, different partition layout.
Don't even try it. Experienced devs have tried to "convert" by various methods and mods, and failed.
But there may be other ways (besides flashing another version's radio) to enable the band(s) you want, read on:

Unlocked Tmobile Note 8 on Sprint

I have been reading a lot of different things about doing this with no definitive answer. It looks like, as of recently, it should be as simple as popping in the sprint Sim card and it should work but I want to be sure before hand. Are there any downsides at all about using tmobile Note 8 on Sprint?
Hi there, I'm not sure but Sprint SIM cards are lock. You can try and see, I had Sprint before and try using there SIM card in my unlock tmobile Galaxy S7 Edge running the unlock S7 Edge firmware, it keep reconfiguring over and over. Maybe you might get better than me.

Sprint doesn't allow other carriers phones on their network. Unlocked or not. T-Mobile does though...
https://forum.xda-developers.com/galaxy-note-8/help/cdma-unlock-verizon-note-8-sprint-t3732364
First question would be: Does Sprint allow to use their SIM cards within non-Sprint devices? That I can't answer. Because I never used Sprint services.
The second question is: Would the T-Mobile radios work with Sprint? LTE radios would most likely work if Sprint allows you to use their SIM card with that device. When LTE is weak or not available the answer is: No. The active radios within T-Mobile and even AT&T Samsung Galaxy Note 8 are both LTE and GSM (Both 3G and 4G). Both Sprint and Verizon uses LTE and CDMA (each has their own CDMA) radios. You can't use GSM radios with Sprint and Verizon right now. Though that will end up changing as CDMA gets phased out.
To top things off each GSM carrier maybe using different frequencies with some (but not all) of their GSM radios. So changing a cellular device from a GSM carrier to another GSM carrier may have limits with GSM services.
Sprint and Verizon services have problems with international areas (outside of the USA) where LTE is weak or no LTE. The reason is that CDMA is very limit or doesn't exist in most international areas (outside of the USA). The areas that CDMA still works internationally (outside of the USA) will be phased out (mostly in the near future). Only a few places outside of the USA, like China, would CDMA not be phased out so quickly. But CDMA will end up completing phased out all together sometime in future (including in the US).
If you want to be truly Global then go for carriers that have both GSM and LTE, like T-Mobile, AT&T, etc. Then once you unlock the SIM then you can use your carrier's roaming (which don't need SIM unlock) or switch the SIM card with a carrier in that country to get service internationally. Just a side note: T-Mobile does have Unlimited 3G international roaming without any extra cost (this is subject to the type of plan you have with T-Mobile).
The only way this would work for you is if the CDMA radio is built into all Note 8 devices. If so then you just need to flash the correct radio firmware to active the correct carrier radios. But I don't believe this is the case. And this wouldn't solve the Sprint SIM lock issue.
The short answer is no. Read this thread. I thought you could just pop in an activated SIM, but it's not that simple.

The areas that CDMA still works internationally (outside of the USA) will be phased out (mostly in the near future). Only a few places outside of the USA, like China, would CDMA not be phased out so quickly. But CDMA will end up completing phased out all together sometime in future (including in the US).
If you want to be truly Global then go for carriers that have both GSM and LTE, like T-Mobile, AT&T, etc. Then once you unlock the SIM then you can use your carrier's roaming (which don't need SIM unlock) or switch the SIM card with a carrier in that country to get service internationally. Just a side note: T-Mobile does have Unlimited 3G international roaming without any extra cost (this is subject to the type of plan you have with T-Mobile).
The only way this would work for you is if the CDMA radio is built into all Note 8 devices. If so then you just need to flash the correct radio firmware to active the correct carrier radios. But I don't believe this is the case. And this wouldn't solve the Sprint SIM lock issue.

ALL US Note 8s (N950U and N950U1) are identical. Same radios. Same hardware. Same everything. Only difference is the preloaded firmware. I actually think the Canadian Note 8s (N950W are the same, too, sonce they can run the N950U firmware).
So it's not an issue of missing a CDMA radio. It's an issue that Sprint will not accept the IMEI for another carrier branded Note 8 (or S8/+). You can only activate Sprint or Factory Unlocked devices on Sprint.
As Note 8 has both GSM and CDMA capabilities, why shouldn't an unlock T-Mobile work with Sprint?

Sprint won't accept any devices on their network unlocked or not if they came from any other carrier. Sprint only allows Sprint phones and factory unlocked devices. Its Sprint, they suck.

On Sprints website it still does not list the tmo note 8 as compatible for BYOD. It says only the note 8 special edition is. However it is not unlikely they stopped blocking the other U.S. carrier versions. People have gotten devices to activate in the past, but with minimal network functionality. Is your Note 8 fully utilizing the LTE network?
Either way this thread brings trouble so its now closed
Sprint allows sprint capable devices such as clean sprint,Boost and such and subsidiaries that run on sprint only.
@cp1024 @Gizmoe
The Special Edition devices are the ones sold directly by Samsung as factory-unlocked models. Samsung over the years has used the term inconsistently across their site and marketing materials.
Only Sprint calls them "Special Edition", otherwise they are the U1 models, vs U for carrier branded.
Which means they as of the time this was printed will only accept this model
Maybe some others have managed to pull something off but this is official answer
my post above is how it has always been in the past
And it ends here
