I read a few threads and am confused, so I thought I would just ask. I have a few 4G LTE devices for Verizon and am ready to switch to AT&T. Let's just say that Verizon and I had an argument and it is time to switch. Plus I would be saving over $50 to switch to AT&T with a month to month with a BYOP plan.
I visited the AT&T store today and had them insert a SIM into my S4. I get the error "This SIM card is from an unknown source" in the banner. I get a signal strength and a H for where the data symbol 4GLTE is. Then it drops the signal and refuses to have a data connection. At this time the APN settings were NOT adjusted. This was a straight out of the box S4 rooted on NC5 with Android version 4.4.2. After messing with the S4 for awhile he moved to the S3 and entered the proper APN settings. It pulled data, but only at EDGE speeds or 1X. Also, my last device, a Samsung Galaxy Tab 2, has no way of editing the APN settings. It is NOT rooted and is still on stock firmware.
My questions are these:
1. Can this be done?
2. What do I need to do to the phone(s)/tablet to make it work?
3. Will I be able to get 4G speeds?
I do not want to purchase phones with AT&T today because I just don't have the money. I already have these devices, I just want to swap them over. I am comfortable with flashing using ODIN and even so far as using safe-strap. I have flashed some custom roms, but my phone is a daily grind phone and I really want something that works 90% of the time.
Thanks in advance for any help!
EDIT:
None of the codes work either:

That thread just asks if the SIM card would work and if they would need to flash a GSM ROM to their S4. That thread does not answer the questions I asked. I just gave my insight after a visit with the AT&T store. Store techs tend to not know as much as the XDA community. That is why I asked here. So no, it is not a redundant thread. I appreciate your answer, but it isn't what I am looking for. Not a straight up yes or no, this or that.
As for the GSM locks I discussed, it was from an experience I had with a Motorola Droid 2 and using it on a local GSM provider in the USA. So yes, that was pre LTE.

My point, which you apparently missed, is that there is no reason for starting up yet another thread to ask questions that have already been answered. That''s why I said that this is redundant.
OK, let me answer your questions.
1. Can this be done?
Yes, you can install an AT&T SIM, set up the APN, and it will work. What bands you get and what bandwidth you get depends on what bands AT&T are using in your area. You won't likely be able to get LTE speed; most likely just Edge. You can't fix that, as it's a limitation of the phone's radio hardware. Again, some people have made claims that you can flash the AT&T GS4 modem on a Verizon phone and change that, but that's pretty risky as it will likely brick your phone.
2. What do I need to do to the phone(s)/tablet to make it work?
It works, for some level of "work". If you're stock,some people have reported that the firmware requires CDMA for some functions, like SMS. I haven't verified that. I was able to send SMS with my phone and a UK SIM which uses the AT&T network.
3. Will I be able to get 4G speeds?
Not likely. For example, see here http://phandroid.com/2012/12/10/nexus-4-att-lte/ - the common band, LTE Band 4, has limited AT&T coverage.
I haven't gone over the specs of the two phones lately to match them up, so that may be worth looking at again.

Thank you for your answer. I decided to trade the phones into AT&T and get a credit towards a Samsung S4 and a Asus Padphone X. After I read a few more posts over the internet and a few more hours figuring out how LTE works I came across the answer. I did miss what you meant and I apologize. Again, thank you for your answer.
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!
I'm overseas right now and I got a SIM card from work and slid it in to my VZW S4. I'm assuming I should have at least got a couple signal bars in the notification bar, as I have another phone with full signal sitting next to me. Also the SIM made a call from a GSM Galaxy note right before I put it in my phone.
With just the Cyta SIM in I get a message (that cannot be dismissed):
Phone activation
This SIM card is from an unknown source.

After changing my network mode to Global and adding the APN according to THIS, I am still not showing any signal bars. I was able to pull up a couple networks in the Network Operators menu, one being Cyta-Vodaphone but still no bars and no connection.
The phone is rooted and on 4.4.2.
Am I missing something?
QUESTION kind of related to the question below.
Hey Guys... If anyone is online, please reply.
I was wondering if there was a way to get the Verizon GS4 to be able
to work on the Metro PCS servers and towers. I know that they have
different types of network bands, but I was just trying to make sure
if there was any way to get the phone to work on that network with
a flashable something in ODIN. My Verizon GS4 is rooted and on the
ROM called Hyperdrive.
Any replies are welcomed. And for the question above, I'm sorry i do not
have an answer for you.

you might be able to get some 3g but i doubt any 4g
To be clear, I have absolutely no idea what I'm doing, and no experience whatsoever with any of this.
Over 12 hours of research I managed to unlock the bootloader, root, and flash my TextNow Moto E with a stock US Cellular ROM. Everything worked fine.
What are the next steps to take, if any? Is it possible to even use a GSM network on this phone? I have an active T-Mobile sim card that the phone simply will not accept. I get a "no sim found" notification.
I attempted this with no success.
To start, su command would not work.
This worked for me on the XT1529, but it might work on the XT1526 as well since they're both LTE/CDMA devices:
root, open /system/build.prop, add the following line to the end: ro.telephony.default_network=10
save, make sure the permissions are still 0644, reboot.
When you check *#*#4636#*#* it should be in LTE/GSM/CDMA mode, and in Settings > Mobile Network it should say "Global".

This didn't work. I ended up experimenting more and softbricked my phone, got stuck in a boot loop. Through curiosity I ended up flashing the phone with a stock xt1527 rom. SIM now recognized as a non supported sim, so that's nice. Still doesn't work.
I cannot post links to screens as a new user, but if you happen to want to see them, message me and I'll link them from my dropbox.
I ended up ordering an unlocked xt1527 last night. However, I would still like to figure this out. Would I perhaps have to flash the modem?

Just tested this - not working. This is a really maddening scenario
I contacted sprint and gave them the IMEI - they tell me that this phone can indeed be unlocked (xt1526), but I would have to do it through TextNow. I've searched for ways to bring up the SIM unlock prompt, but it simply doesn't show up with any of the methods found. :s

I still have my sprint model as well, and have the MSL code. But I have also never found a way to enter it for unlock. I've tried using active ATT and VZW SIMs, and also tried flashing the USC modem on it - still works on sprint / ringplus, but also still won't acknowledge ATT or VZW SIMs.

I don't know for sure, but i did read in another place on here somewhere about an "embedded card" that sprint put in another phone. I wonder if that is the case with this one? If not, all i can really think of is that there is something in place that motorola made specifically for the sprint model. We know its not modem related, so it must be somewhere else, in the NAM, or something like that. One thing i did accomplish was to get another bar, (it had no signal and looked like an outline, but it was there), show up by editing the build prop with a specific line and then rebooting. Odd thing is, its the same thing that showed up when i attemped to flash another stock firmware. The firmware i flashed was for the xt1526, retail us. Which leads me to think it might be a band issue, as someone else mentioned in another thread on here somewhere. I mean, it would make sense with the no signal and everything. Sorry for the long post, just thinking out loud i guess.

Yes, I'm hoping there is a fix somehow. I'm ok to use the phone on WiFi, but it is otherwise useless to me. I'd like to have a backup phone in case my first Moto E dies, they are really rugged. I have experimented all day without success. Experimenting with build.prop does nothing. I export the build.prop text and post it just for reference, if anyone cares to play with it.

its not an embedded card in the textnow wireless version as ive taken the sim card out of mine. The S3 was an imbedded card, but not this device. Im also searching for a method to sim unlock this little bugger. Ill let you know what i find out

I talked to Sprint - they told me TextNow has to SIM unlock the device. I talked to TextNow - They told me the device IS SIM unlocked. So, there's that if anybody is wondering. I've almost abandoned this experiment, but it's still in the back of my mind. In other news - the new Moto E 2015 I received has a yellowed display. 2/3 brand new Motorola devices I received had display issues. Excellent phones, poor quality control it seems.

i got my E2015 from textnow for $10 as a refurb and its solid as a rock so far. I stumbled upon this thread and it looks promising, but im at work and we use citrix clients and not actual computers so i cant run it here, but ill give it a whirl when i get home. I do also believe that its GSM unlocked
Trying to make my XT1526 (Boost stock ROM) work with GSM, and got stuck on something weird. Inserted a SIM card from China Mobile, changed the network mode to "Global" and turned on roaming, after a while it got successfully registered on T-Mobile network, both voice and data. Yet, when I inserted a T-Mobile SIM card, the phone gave an "Invalid SIM card" error, and simply refused to connect. Thought it might be an issue with APN setting, but I couldn't manually add the T-Mo APN to the phone (in fact it wouldn't take any APN).
I think the phone's hardware is capable of LTE/CDMA/GSM. It's a just matter of figuring out the right configuration.

Why so tricky? Why? I am truly of no help, I just started the thread. Learning as I go...funny thing. Upon flashing again with the xt1527, and flashing the modem with a different modem software, the phone still shows to be a sprint modem software.
I wonder if the "fastboot oem config carrier" option would do any good?
DSU is tricky because it involved modifying the NV values thats buried in the radio software and it has a similar access issue to SU. I have (among many others) a Sprint S5 (G900P) and achieving DSU on it was the work of some SERIOUS developers. The config carrier might be of some help, but i havent delved into it yet, and im not sure if id fully understand what it means anyways. Additionally, Moto devices are tricky period. I had 2 Razrs (one xt 912 and one xt910), one of them was GSM unlockable and the other wasnt. Motorola mobile phone division has also changed hands recently, so its direction has also changed. Basically, whats needed here is either a ton of forum scouring or a developer to actually pay attention to this device, or a bit of both
