Help switch USCC gs3 to Verizon gs3 - Galaxy S III General

So I US Cellular is done in Chicago and I refuse to purchase another phone if I can change over with my current one.
I am already rooted and wondering what I would need to do attempt to get the cmda to recognize Verizon. PLEASE HELP!

Looks like you're in the wrong section. This is for the international GS 3 rather than any us variant so any help probably will either be a. Harmful to the device or b. Not helpful at all

[Q] "Unlocking" AT&T S4 questions

Now I have had previous Samsung Galaxy phones that I have rooted and I'm very familiar with the whole process.
However, I have never used a phone that was bought for one carrier and used on another.
I'm planning to purchase an AT&T Galaxy S4 and using it on the T-Mobile network (wish me luck).
What would be the best way to unlock the AT&T phone to use a T-Mobile SIM?
http://forum.xda-developers.com/showthread.php?t=2285431​This is what I have found, but I heard something about a USB unlock being more successful.
Once the phone is "Unlocked", and I root the device, should I be using the AT&T ROMs section, or T-Mobile? I'm going to guess AT&T because they are somewhat hardware dependent?
Lastly, will this AT&T version limit my signal in anyway (not accounting for the already possibility of bad signal)?
Meaning the AT&T version only picks up the lesser of the T-Mobile bands or signals.
If I sound like an idiot, I apologize. I've done some research and cant seem to find the right keywords to search.
Thanks in advance for any information.

I'd advise you buy a T-Mobile Galaxy s4. Our bootloader is locked and the newest updafe only has a root exploit and

I am using i337 with tmobiles sim card. I get 4g at over 10mbs and even over 20mbs on some good dsys. I usually use att roms although I've found that i9505 and tmobile work too. Just have to stick with loki'ed kernels. Hope this helps.
It does, thank you.
So look for a ROM with Loki kernels?
And which unlock method did you use to get the T-Mobile SIM to work?
The one above or a different one
Thanks for the info

Nexus 4

Hello,
Been wanting to root and maybe even flash a rom to my Nexus 4. But I've hesitant because my nexus 4 service is provided by any of the popular carriers(Verizon, AT&T, Sprint, T-Mobile) but the carrier is exclusive to the 4 surrounding states I'm from(Arizona, Utah, Colorado, New Mexico)
So my question is can my phone be rooted? Since it's provided by any of the above carriers
Yep. It has nothing to do with who you have service with.

Okay, thanks I was worried that it might mess up the phone if I tried to root.
So I guess everything is built around [Build Number] or Android version

[q] help please!

OK, so I have a Sprint Galaxy S 4 with cusom recovery and rom (rooted/unlocked). I want to sell it so that I can buy the Nexus 5. Can people with different services use the phone on networks like T-mobile, Verizon, AT&T, etc.? Is there anything that I can tweak to make it available for those networks? Thanks in advance!
No.

It can be unlocked to work on Tmobile in some markets depending on what frequencies are available where you live. I am currently using my SPH-L720 on tmobile in PHX AZ . Some users have reported Net10 working and others ATT but I have never investigated this. If you want to see how it works I have compiled a guide that outlines the steps I took to make it work on Tmobile. http://forum.xda-developers.com/showthread.php?t=2530610 Also look in the International SIM unlock thread in Development and the GSM data thread in general for further tips.
Also I'm sure it can be flashed to boost you just need the PRL file to flash. Check out this thread.

Verizon, Sprint, T mobile S4 on ATT LTE?

Hi.
Can s4 from above careers work with ATT LTE? I know sprint and Verizon are cdma but looks like Samsung added sim card slots on all variants. Looking to buy a used one and not so many selling form att.
Thanks.

It should work as long as it's not carrier locked and the bands are all the same. (Buy a Google Play Edition or a international variant if possible.)
Smack that thanks button If I helped!
Always make a nandroid backup before trying anything risky.

If you don't want to spend the money get a att phone on contract ...
Phones cost money, especially off contract.
Plus a used s4 is going to cost 3 to 4 hundred dollars, more if they are carrier unlocked.
