Gentlemen,
I currently got myself an AT&T model galaxy s4 and Im looking to run it on Tmobile. My question is what advice do you guys have for a noob like me?
Do I need to unlock the bootloader?
Is there a specific ROM I should use?
How do I get MMS and group text to work?
What's the best method to unlock my GS4?
Thanks!
The best method to unlock your GS4 is to request the code from AT&T if you have an account with them.
To get MMS to work you need to edit the APN settings to t-mobile's configuration. You may need to copy this from a t-mobile phone, ask a friend, or Google it.
The instructions to change the APN are on the T-Mobile website. Just Google it or fish around on their site. I found it somewhere under the bring your own phone options.

Hey guys I need help... I got my wife an unlocked AT&T LG G2. I set up the APN setting and the LTE was working but as soon as I don't have a strong signal the phone drops to gsm and it doesn't give me the options to include other frequencies on settings. I worked with T-Mobile to fix the issue but they don't have a fix. I was adviced to flash a T-Mobile stock ROM is this possible if the build model is different?
I have a US Cellular Note 4 unlocked.
I was trying to find out if there is anyway to get it to work on AT&T's network.
I know the stock US Cellular rom will not work, since it doesn't have any options for a GSM network.
I was wanting to try another rom, but not sure what to try..
The phone is rooted with TWRP installed..
Any help or comments are appreciated..
Any luck?
Before I rooted my verizon galaxy s5 I was able to use ATT sim cards but the phone would not get any service whatsoever with a tmobile sim or metro pcs sim. Everyone i spoke to at least was able to connect to the tmobile or metro pcs network, even if they were having data issues...but I was not even able to get a network signal. Finally, I rooted the phone and am using a tmobile rom thinking that may help. But no luck. For some reason my phone will not register itself on tmobile or metro pcs, Not even to just connecto to the network to make phone calls. I tried 2 different tomible roms and i think an att rom and no luck whatsoever. Anybody else experience this issue? Is there a root function or service menu that I need to access to enable the proper band? Is rooting the phone even going to change anything? Makes no sense how every other verizon s5 out there has no problem connecting to tmobile or metro but I have the only one. Ive scoured the forums and have yet to find any answer....thoughts? Oh, I also tried every APN settings combination imaginable. Even other carriers just because I was getting nowhere with the tmobile and metro APNs.
Quite a lot of your thread made absolutely no sense, so I'm not sure if this will help.
Look for a tar.md5 that contains the stock modem partition for the Verizon S5, and flash it through Odin.
Are you bootloader unlocked? I would just flash a generic klte rom, like Cyanogenmod, instead of flashing an ATT or T-Mobile rom.

According to a few people i spoke with the root for verizon s5 can only accept TW roms. And to clear up anything that doesnt make sense. my verizon s5 will not get any service with tmobile or metro. Works fine with att. So i decided to root. After rooting still no luck. However, before I rooted I was getting no bars at all. After rooting I was actually getting service bars but still would not get any actual service. I tried every APN setting I could find and still no luck. Thats all. I will try your advice as far as flashing the tar.md5 and let you know.

There was a bootloader unlock exploit released - it allows any rom to be flashed. It's been in the top development posts for weeks. Go check that out, and you can flash cyanogenmod.
I actually am in a similiar situation except I am already on CM13 using a previously Verizon S5, I just started Tmobile service yesterday and in general I can make calls but data is rather inconsistent. Example right now when I make it call it falls down to 3g (Normal) but when I disconnect it tries to connect to H+ then 3G but all of them don't supply it data so it just swaps around 3G LTE and H+ and I have to airplane mode on/off to fix it. So this person may still have issues using CM13. I did already go over the APN information with people from TMobile and from post around the web. Does anyone think that flashing the Tmobile s5 modem stuff will fix this?
you just need to get the correct APN settings

I've tried the correct son settings. It didn't work. I used the settings found online for T-Mobile. I called T-Mobile. Non of the settings worked. I flashed back the the stock rom. No joy. flashed a verizon s5 rom again. No joy. I am starting to think that this is the only verizon s5 that won't allow t to register on T-Mobile's network.
Hello guys,
Im a bit desperate, when I try to enable mobile hotspot on my ATT Unlocked LG G6 (H871) it says auth failed and just won't share internet connection not thru wifi nor USB cable.
Please I will really appreciate your help, I need to work with my computer all the time using this function.
Thank you
If u have an att SIM card the function will work but if u have any other gsm SIM like straight talk the functions won't work as the OS is still essentially att's android.
What network are you using? Is it att or another one?
I recommend you check your phone's APN settings.
