So I recently moved an VZW S4 over to AT&T Go for a friend. So far everything is mostly working fine running Eclipse ROM (VZW ROM). But I am wondering on a few things here as even on global mode with the AT&T Go APN's inserted at best we're both seeing HSPA+ but most of the time it's staying on 3G connection. Text and phone are working fine.
1 ) Should I swap out the NC5 modem for an AT&T one?
2 ) Should I swap out to some kind of AT&T ROM like the Safestrap version of the S4 Google Edition ROM?
Any input would be greatly appreciated and thanks in advance.
Bump so this doesn't get lost.
Another bump I really could use help here.

I just bought a brand new Verizon S4 that has never been activated on Verizon for $125. I am trying to get it working with a prepaid carrier in the US. I have been reading that it can be done with T-Mobile and ATT but am not sure where to start with this thing. For starters, the Android OS version is 4.3. I know there is an update out for it through Verizon. I can't do the update OTA with no Verizon service. I'd like to get this thing as close to stock Android/Samsung as possible and kill all the Verizon BS and then get it working on StraightTalk, Cricket, SIMple Mobile, or MetroPCS. Can anyone give me a good place to start or any tips. I've flashed ROMs before, changed PRLs, etc, so I'm no dummy when it comes to this stuff. The terminology/technology has changed some since I was messing with Boost Mobile phones. Any help would be greatly appreciated! Thanks!

Try searching.
You will need to ODIN to 4.4.2.
You will then need to root with "towelroot".
The phone should work with most any GSM carrier with the right setting. (T-Mobile, AT&T and Metro GSM).
Which will give you LTE, I can't answer.

I have used ODIN before when working with my Samsung Galaxy Prevail through Boost Mobile so I'm sure I can figure it out. Thanks for the info. I tried searching and found all kinds of different terminology such as SafeStrap and talking about the different bootloaders. It's a little overwhelming, but I'm sure I can figure it out. I did all of my original stuff through AndroidForums and there as a root section with all kinds of guides, FAQs, etc. Is there a beginners guide or FAQ for the Verizon S4?
I have read where I need to change the APN settings to get HSPA+ or 4G LTE with the different GSM carriers. It seems like HSPA+ is the best I'll get and that's through ATT. I'll keep digging! Thanks!
After 10 years with Verizon, I had enough (long story)... Switched over to T-Mobile recently with my Verizon Galaxy S5 Phone, however I have a few questions.
When I was on VZW I was able to root with towlroot, installed xPosed, and removed the Verizon bloatware. I then inserted the SIM from T-Mobile and made adjustments to the APN. It all seems to be working fine. I understand I will not get the full bandwidth, and I am OK because it was not worth $600 to purchase a new phone (Actually 3 new phones).
My questions are:
1) Should/Can I install SafeStrap and use one of the T-Mobile ROM, Kernals, etc... to be a "true" T-Mobile mobile phone?
2) Are there any T-Mobile specific APK's I should have?
3) I assume I can not get the wireless calling which T-Mobile uses?
4) Any other tips and trick from people that did the same thing?
So far happy with T-Mobile. Thanks in advance for the help.

Thank questions answered. I will search around.
I have mdk Verizon s4 rooted and custom recovery. i'm looking to switch the phone from verizon to at&t will i be able to just flash a rom that has at&t pack like hyperdrive and get an at&t sim card. is that possible? is there any other way i can do this while still getting 4g lte? thanks in advance
The ROM and recovery do not matter. The VZ S4 is unlocked already from Verizon.
I don't know about ATT specifically, but I am using a straight talk plan with the ATT SIM card and it works fine. You just have to update your APN settings but they tell you exactly how.
The only drawback is you will not get LTE , at least not in NY where I am.
I get HSPA+ speeds which seem fast enough for anything I use including streaming video etc.
If you can get LTE to work, let me know.

thanks for the help i will check with att and do some more research to see if i can get the lte working if not then hspa+ isnt so bad
This is a little bit of a nube question but I've never switched form Verizon before. I recently switched to T-Mobile and the SIM works perfectly with my phone after I modified the APN. Is there any way that I could get the software updates from T-Mobile? And also if there would be a ROM that would be for a T-Mobile S4 that would work with SS on Verizon. Thank you guys for you help. Much appreciated in advance.
I'm currently using my bone stock untouched Verizon max on t mobile. Looking for a rom that will work well on this carrier, or better than the stock Verizon rom in global mode. I did put in apn settings however mms msg's are hit or miss as well as lte. I get lte randomly, but mostly stay in "h" but the factory Verizon rom won't let me edit carrier code settings (310-260 for t-mobile).
So in the short if anyone has successfully done the switch to t-mobile with their Verizon variant one max and what rom worked the best for you or worked well in general would be appreciated.
Thanks
my experience
I have the sprint version and I am using it on t-mobile. Vipers rom has the best stability and options. You should be able to edit apns and everything on there. I was having issues but I believe mine to be strictly from being the sprint version, which i know i should've found the verizon one, but too late lol.
I was running CM11 and everything was working for me but I had random lockups when the phone was asleep so i went back to using Viper rom.
