[Q] AT&T Galaxy S4 with T-Mobile Help - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

So I recently got a Galaxy S4 from a friend and unlocked it to use on T-Mobile. I got it unlocked with guides on here but I haven't found a way to get faster data speeds. I've been searching on here for a way to maybe get HSPA+ and seen some people have got some faster speeds. Hopefully someone can provide some help because I'm completely lost when it comes to the different bands and what they are.

yes

[Q] Sprint S5 can be used on T-mobile?

Just got a Galaxy S5 from a vendor for free but with Sprint. I'm on t-Mobile, is there any way to make it work with t-Mobile by chance? Sorry haven't rooted or ROM'd a phone since my good ole days on the HTC EVO. I tried to search the forums, apologize if this has been asked and answered.

I have the same question...I'm not on Tmobile yet but I have a Sim card and was going to try and activate but I think I'll Root and Custom Recovery first...My device is one I got a good price because it has a bad ESN for Sprint so yeah...I hope it can go on Tmobile :silly:
* I'm not 100% sure but I think the Sprint S5's are GSM Unlocked.....Can some one confirm?

If it supports the LTE bands that TMO uses, then go for it.
Check out gsmarena or some other sites to compare which LTE bands it supports and for which bands TMO is using.
But its quite likely it does NOT support all LTE bands, if any.
i dont think it can
unlocking it only lets you use it internationally

I tried putting my SIM card in, says Not Valid SIM. I'm guessing i could probably get around that somehow but i don't know if all the LTE bands are supported. I'm busy with work but if i somehow figure it out i will post something. But i guess i should start with the radio's as suggested.

[Q] Anyone using a t-mobile s5 on at&t?

I've got the AT&T s5 and I love it, but I'd love it MORE if I didn't have to worry about the locked bootloader. I'm tempted to get a Tmobile s5 and root that. Is anyone actually using a Tmobile s5 on AT&T service and if so, how good are the data speeds, is there anything that you can't do with the Tmobile on AT&T, for instance does surfing the web during a phone call work or not, that kind of thing. I very much appreciate any info on this. I know other Tmobile phones are working OK but I need to know obviously about the s5 in particular.
I do know that I will need to get an unlock code for it, no problem there, I do plan to install custom ROMs on it as well.

Yeah, there might be one or two. Thousand. Minimum.
G900T = G900A + two extra bands
Baseband works fine on either system
Lots of existing threads on the subject too

[Q] Will my Unlocked Sprint S4 work with a Verizon prepaid SIM?

I have been doing research and searching these forums for a few days now, I'm trying to not be one of those people who ask questions that have been answered. But at this point I'm at the end of the road.
I bought a Sprint Galaxy S4, model SPH-L720.
I unlocked it using this method Sprint Galaxy S IV SPH-L720 SIM Unlock Method
Reverted back to MDC baseband and all that good stuff, just as instructed. It seemed to have went well without a hitch.
My question now is:
I want to buy one of these Verizon 4G Sim Activation Kits from walmart
Is it possible that I can buy one of those, insert the SIM into my unlocked Sprint S4, and have a working phone? I ask because I don't want to drop $50 if it doesn't have a chance of working. The instructions for this say that it will work with a VERIZON S4, but since my SPRINT S4 is unlocked, should that be okay?
I don't know much, but in my reading I found that Sprint and Verizon both use CDMA, not GSM. So I figured I had a better chance of this phone working if I go with Verizon because of this.
I am in the United States.
If you need any other information or screen shots please let me know, thank you for taking the time to help me out!!
EDIT: would it be possible to test it out, if one of my friends has a verizon phone under contract, and I took their SIM and inserted it into my phone?
Try it.
Like the guy above me said. Try it. One way to find out. Personally I don't think it would work. As the whole point of unlocking the sprint Gs4 is to use it on GSM networks. From what I know you have to flash the sprint phone to Verizon. Plus you WONT get LTE on Verizon because the bands are not supported. So you'll only get 3g.

thank you for the info! i'm just learning about all of this, so i don't have a firm grip on everything yet.
in the tutorial i used and linked above, the file I used with Odin was actually titled "S4 Flasher", so I believe I unlocked it and flashed it with this? Again, Im sorry, Ive tried searching and am just looking for verification if Im correct.
I'm not worried about LTE, 3G is fine really. Also, I'm not set on Verizon, I just want my phone to work, doesn't matter what network I'm using. If it would be "safer" or a better bet to get into a GSM prepaid, I will do that instead. I was just under the assumption (incorrectly probably lol) that since sprint is CDMA, that going to another CDMA carrier would be easier.
Cricket, Net10, StraightTalk, and AT&T etc are all available at the store I think if I go GSM
Again thanks for taking the time to help everyone!

I unlocked my sprint GS4 and went to Cricket. And I've been happier than when i was with Sprint (service wise). I have signal in 98% of the places I go to. Which is a HUGE improvement over sprint. And even though this phone only connects to HSPA+ which is capped at 3.5 Mbps its plenty fast for all my daily activities. So I recommend a GSM prepaid.

[Q] Help!! Verizon Branded S5

I decided to follow a buddies advise and save $100 and order a verizon s5 instead of ordering a no brand, unlocked one on ebay. it is basically the same phone for specs and what not, just verizon bloated. So, i bought it and called att and got the sim card activated with the phone and now my phone has data and phone. my problelms are this:
I want to get rid of all the bloat stuff
I cant use the tethering on anything because it wants a verizon subscription and i am with att.
my data speed isnt the 4g/LTE that i should be getting. according to the att rep, PROBABLY because it is a verizon phone. i get H+ speed,
which a buddy tells me is basically "3.5G".....lol
i have been able to get root access as one of the fellow techs at the shop is pretty good with this stuff. but he tells me that everything he sees/knows,
it cant be done because of the bootloader they used.
is there anything i can do to be able to do the tethering and get my speeds up? that at least would be suff!! i am a computer tech so i can follow some direction if you
can just point me in the right direction, i would be ever so grateful. thanks in advance....

update
i have done some research and found this tool called safestrap. LOVING IT! was able to get it installed and working with little to no effort. downloaded a couple of roms and loaded them into a rom slot(not stock) and everything is what i wanted with the exception of my data speed. still cant seem to get the 4g/lte working no matter what. ATT claims it is because it is a verizon phone...most likely. got the bloat stuff off and the tethering is working now. only issues now is the damn data speed. connected to wifi most of the time but when i am not, wow...is it alot slower than usual. any help on that would be great!! thanks again peeps....your site is AWESOME!!!

There's no help to give. You can't get 4G speeds on AT&T or T-Mobile with a Verizon phone.

I read on one site that you can actually switch S5s to other CSC codes by loading the desired stock firmware and using Kies. It said Kies sees the mismatched CSC and uses the one loaded instead of the device's. I haven't tried it, but I was wondering if anyone has?

How Do You Get 4G LTE from AT&T on SM-G935V?

Hello, I'm a bit new to all this, so please bear with me if I sound a bit out of the know. I currently have a SM-G935V, from Verizon of course, but I recently switched to AT&T as they have better service for me, however, the best connection I seem to get at the moment is H+ (it switches from 3G to H and H+ but I know for a fact that there is 4G LTE in my area). Not sure exactly what to do in order to get consistent 4G LTE. I have called to troubleshoot with technical support; we set up a few APN's, but to no avail. Would flashing the SM-G935U firmware help me at all, or am I doomed from the start since I have the Verizon variant (they claim that all of their LTE phones are unlocked)? Also, I heard that for the US version of the phone they will not let you flash anything on them. Is that true? Thanks for any help or advice in advance, I greatly appreciate it!

I'm not 100% sure AT&T is included but you can try following the instructions and flashing Jrkruse's U Firmware ROM here: https://forum.xda-developers.com/verizon-s7-edge/development/rom-t3603231

Thanks! Just an update for anyone who reads this thread having the same problem. Flashing the U firmware did in fact do the trick, but sadly I am not getting HD calling. Data works on LTE just fine though.
