Yes, you might have to add the AT&T APN though.
Will i have to flash any different kernels or factory restore my phone or ODIN back to stock? Or can I just insert the micro sim and it will be on At&t? Also, what is the APN i have to enter?

Im pretty sure you can just pop the sim card in and go, a search for galaxy s4 apn settings ATT in google should get you the answer on the other. A buddy of mine just switched to ATT and popped the sim in, and did not have to do anything, but YMMV.
You will get hspa+ and the apn I used on the dna to test it was apn name hspa or att and apn: phone. That was it. Make sure the network mode is on gsm

I am using mine on At&t ... ive had a few issues. 1st, the apn works fine for data but I never got mms working. I did get mms working using go sms pro and having it use its own MMSC settings (same as what I set in the apn settings). 2nd, im on ME7 firmware and I can get a # sign at command prompt but have failed to be able to get supersu and permaroot. This means I havent been able to get to tje secret menu to turn on lte bands 4 and 17. But theoretically should be able to support LTE.
Anyone else have similar issues?

Another issue I have is the incoming caller id doesnt include the 1 but it does include the + ... which is an invalid dialing combination when calling back a number. Anyone know a setting change for that

I'm on beans build 6 on a vzw version gn2 and when I pop an att or tmo sim I don't seem to get 3g, only an "H+" symbol. Phone calls work fine. The gn2 seems to known which sim is in and picks up the correct carrier and the apn info that bean included in this build does show up. Whether they are right may be a different story but I'd assume it is. I've also tried this on cleanrom se vzw 1.0 with the apn hack from the other thread and it didn't work then either with a tmo sim, same H+ symbol. Am I missing something? Does this work for others? I'm in the bay area so I know I should have good connectivity on those carriers., not sure if this phone just doesn't have the right radios for 3g on att or tmo?

Can someone please help me out? I'm using a bell lte SIM card, however, I have no problems getting gsm on Verizon roms (phone doesn't support bell lte). The reason I want a gsm rom is because the verizon roms dont have functioning mms with my provider.
When I use a gsm Rom I get "SIM card not found".when trying to enter my apn settings. Tweaker apn doesn't work either.
What can I do?

Is there a way I can get my Verizon S4 to work with a Straight Talk AT&T SIM card?! Please say yes, so I can get rid of this expensive A$$ bill?!

Yes I'm using my at&t straight talk sim on the verizon s4 and it works great!
Is there anything special I have to do with my phone? When I order the sim card from straight talk it won't let me select the cdma option so, should I just select gsm as if I have a AT&T Galaxy S4?

CDMA does not use SIM cards. The S4 is a CDMA/GSM/LTE device. AT&T is a GSM network.
You might have to edit the APN settings to use Straight Talk.

The Verizon S4 is a CDMA phone AND a GSM phone. I believe they made it this way so you can go to about any other country in the world and still use your phone - or it was just cheaper to mass produce the radios with everything in it.
Anyway the only thing to change is the APN settings to
Name=Straight Talk
APN=att.mvno
Proxy=proxy.mvno.tracfone.com
Port=80
MMSC=http://mmsc.cingular.com
MMS proxy=mms2.tracfone.com
works perfect. However I did just find a small problem. I have flashed both cyanogenmod and Liquidsmooth AOSP ROMS and they do not work with at&t ST sim - when I call the phone it does not answer or register the call at all. Not sure what the problem is, seems like for some reason it is not registering with the at&t network. Trying to find a fix. However, the phone has worked fine with all TW based ROMS I've tried.
Ok thanks for the information but I have one more question... I am rooted with Clean Rom 1.5, do I have to unroot my phone? Will I still be able use wife tether or foxfi? I heard AT&T took foxfi away.

Oops just saw that you messaged me - yes just choose GSM. You do not have to unroot your phone but like I said in the last post - I cannot get AOSP roms to receive or make calls - data works - but not phone calls - which is rather strange and I'm sure can be fixed but nothing I have tried seems to work.
GSM is fine but in reality once you get the right LTE bands turned on, would it be better in global?

What kind of data do you see on AT&T? HSPA+? 3G? 2G?
I have a Verizon SG4 with AT&T SIM working, voice and data. Data is only H+.
How can I get 4G or LTE?
Thank you!
How did you get ATT working? Just pop in the Sim card and enter the APNs? And LTE won't work, Verizon GS3 has Non Att LTE bands.

Yup, just popped in the SIM, went to AT&T store, copied in the APN from a working sg4, and voice and HSPA+ data works.
I have a SG4 not sg3. Doesnt teh SG4 have the same frequency bands?
Here is a tip buy an att phone if you're gonna use att
Lte bands for Verizon and att are different your lte won't ever work on att with a Verizon phone

Gs4. My bad. Lol. I blanked out for a minute. Lmao. But yes, LTE will never work with an ATT Sim card in a Verizon phone

I'm thinking about using my Verizon S4 with Airvoice, an ATT mnvo. I don't care about LTE but can you post what the APN settings you entered are ?
Hi I was trying to use my s4 on AT&T.some people at you can edit apn out of the box without hacking but I'm not able to do it. I'm rooted on me7. What are my options?I tried to search this issue but didn't get any results back

You can't edit APNs if you have a Verizon SIM installed. Once you install a non-Verizon SIM, you'll be able to add and edit APNs.
At least that's how my VZ GS4 works.

OK, here's what I just did - VZ SCH-i545.
Powered it down and swapped in my european SIM.
After the VZ logo startup stuff, I get the prompt for the PIN to unlock the SIM.
Then the OS unlock PIN,
Now I have a "Non-Verizon SIM" warning and a "Roaming Network Access" warning.
My phone now says "AT&T UK". My network mode is Global. In "Access Point Names", there's just "LTE - Verizon Internet" but that's greyed out. The "+" at the bottom of the screen is now active. I press that, enter the APN, and it's ready to go.
My mobile network works and is apparently giving me a UK IP address.
So, unless there's something in the phone that's rejecting AT&T SIMs, I'm at a loss.
