I have a Samsung Galaxy S4 locked to U.S. cellular (model SCH-R970). I would like to know how I could swap my service to Straight talk. Is there some type of rom that I could flash to the phone to unlock it?

Hey All. I currently have a Galaxy Nexus with a ATT Straight Talk SIM. I am buying a T-Moble Galaxy S4 today for $320. I want to use it as my main phone, but I know I will have to unlock it and cut the SIM card. After I unlock it will I be able to get 4G speeds? Or will the band difference screw me? What if I was to get the new LTE straight Talk SIM Card?
I recently purchased a Samsung galaxy s4 (t mobile). I unlocked it and now I use it with straight talk. My problem is, when I visit home, my cell signal sucks, I was told that what ever phone one uses, straight talk goes off of those particular towers. How can I change my settngs to att so that I can get better coverage?
[Q] Can I be on Sprint and T-mobile at the same time after domestic unlock?
I was planning to a get a S4 L720 on Freedompop (runs on sprint) for the free 500mb data plan and I was thinking if i could get my tmobile prepaid voice only to work in conjunction with the phone. Could I get the CDMA and GSM at the same after I do the domestic unlock for the phone?
Would flashing a Tmobile Rom and using sprint apn work?
No it's not possible to do. Either one.or the other.
ok. thanks for the help
I was under the impression that the sprint GALAXY S4 didn't have the GSM antenna. Is that incorrect?

No
Also you can switch effortlessly between tmobile and sprint by changing your network preference. But you can't receive calls on the two networks simultaneously.
I have an Sprint Galaxy S4 SPH-L720 unlocked and rooted on T-Mobile right now.
The only issue is when I call it goes through but the phone app hangs.
Sound doesn't work either.
Hi guys, new here. Used the place a lot when i needed help, then decided to make a account.
Anyway, i couldnt find a Straight Talk galaxy s4 specific forum so i figured the main s4 forum is where i should post this.
I have 2 Straight talk galaxy s4's i bought new, and im currently in cricket. Well i need to replace my old CDMA s4 with a new GSM one. The straight talk s4's i got are the ATT tower versions. Now, when i put a att or gsm cricket sim in, they say invalid sim. But read att sims fine. If i put the straight talk or gsm cricket sim in a att phone.. Theyre read fine. Which i dont understand. So my question is, can i flash a ATT stock touchwiz rom to them via odin to make them read the att and cricket sim's? Id just try it but dont want to brick them, figured i would ask first in case somebody already tried.
Both phones are identical. Specs are:
16gb black Straight talk galaxy s4
Model No: SM-S975L(GP)
Android 4.3
Touchwiz, un rooted, brand new barely even been powered on.
Thanks!
Current Straight Talk S4 units use T-Mobile towers, not AT&T. Flashing a new ROM won't make them read the SIM cards you're trying to use, and for the Straight Talk S4 will likely hard brick it. Your phones need to be carrier unlocked, which only Straight Talk, at their discretion, can do. As multiple users here have discovered, purchasing an unlock code does not permanently unlock the S4 and half the time doesn't even work.

Thanks for the reply!
I didnt think it would work but figured it couldnt hurt to ask. I'll contact straight talk, however from what ive hward they usually wont unlock phones. But, ill try. Thank you!
Just bought my Straight Talk Samsung Galaxy S8 from Walmart, so I took the Tracfone sim card out and put a AT&T sim card into it, it works!
My question: Is the Straight Talk Samsung Galaxy S8 sim unlocked by default?
Thanks in advance
I tested mine with all four major carriers, ATT, Verizon, T-Mobile and started a Sprint free year on the device, so I guess the Walmart Straight Talk S8 is fully unlocked
