Hey folks. I will living in Kuwait for the next year, and I brought my Verizon LG G3 VS985. Once I got here, I purchased a Kuwaiti SIM that runs off ZAIN towers, and a 4G mobile hotspot. This works great and I can connect all my devices, but it's a pain to lug around a hotspot with me when I am out. I read online my G3 is factory unlocked, but when I put the SIM in my phone, it tells me a non-Verizon SIM has been inserted. I have played with all of the mobile network settings, and I can register on the local Kuwait networks, but my phone will never connect. I have tried global, LTE, GSM, UMTS, CDMA, 3GPP multi, etc. In the status bar, the signal strength and type of network will change accordingly, but will always be grayed out. I am trying to figure this out, but it's driving me crazy.
Can any of you experts help me out?
Thank you in advance.
I can only give a little info, but not really what you're looking for. To be clear, the phone is unlocked. The complaint that you have a non-Verizon SIM inserted is more informational/annoyance. To my understanding, it doesn't keep you from using any other SIM, it just annoys you when you do. *If* you were rooted, I believe the G3TweaksBox Xposed module has an option to take care of that, but verify that before quoting me on it.
I know one key item to keep in mind is that the VS985 only handles certain radio frequencies, and they might not match all of the frequencies that your current network requires, or there might only barely be some overlap.
There are some radio frequencies that can be unlocked on the VS985. There are informational threads in the General section and maybe some in the Q&A section that might help as well. When viewing the General section, use the search box near the top right if on a web browser (not Tapatalk) and I'd try the keyword "unlock" or try "radio" or "frequency", "frequencies", or "band". "unlock" and "band" might produce the most appropriate search results.
Speaking of General and Q&A sections, in the future please post new question threads in Q&A. I'll ask a moderator to move this thread there.
I know I've seen one of the informational threads I think in this section and someone lists the frequencies that are able to be unlocked on this phone. The information might not be in the first post of the thread - I don't recall as I've never had to unlock any bands for my use. From there, if I were you I'd try to find out what bands your current network requires or supports, to find out if unlocking any particular bands might help.
Good luck!

I have been around the forum for many years now, but am new to Android. I purchased a GT-i9100 in India for work travel between US and there. I have rooted and upgraded to 2.3.4, and applied a new kernel to remove the exclamation point. So, with that said, here is my question:
I am in the US right now, and in an area supported by T Mobile HSPA, but the phone will only connect to Edge. I am PRETTY sure it was only connecting to Edge before I did the work, but I cannot be sure. Would there be anything I did to the phone that would prevent it from getting onto the "4G" network? Is there anything I need to do now to change so it can connect?
I am not sure if this is related either, but I have a Verizon LTE data card, and if I place that SIM in the GT-i9100, it won't recognize it at all. It seems to only see T Mobile and ATT in the US.
I have spoken to T Mobile and they confirmed the 4g availability where I am, and they also reset my network connection, so the issue does not appear to be on my account or with TMobile.
Sorry for the long post, but I have been searching around and can't seem to get my small mind around resolution.
The SGS2 does not work with T-Mobile's 4G bands here in the US. If you want 4G you'll need AT&T.

That's because there is no resolution. As stated in several other threads on these forums (learn to do a search, and there's even one on the main page of Q/A right now) THERE IS NO WAY to get 3G on T-Mobile. The hardware in the phone does not support their 1700MHZ band.
Your 2 options:
1. Buy a T-Mobile phone
2. Switch to AT&T
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:

It was an answer to this same question asked by you. This thread is redundant.

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 was told by a "Verizon salesperson" that unlocking a phone doesn't give you the ability to use everyone of the service providers.different providers use different signals (att,T-Mobile can't use sprint,Verizon etc...).is this correct,or was he blowing smoke.
Seems a waste of time to unlock a phone if you can use only a limited number of providers.
If someone can direct me to a thread on this topic or have an answer it is appreciated.thnx
If you google "difference between gsm and cdma" you'll find a number of good explanations. The Gizmodo article would be a good place to start.
It really depends on the phone. Most phones are GSM/CDMA only. There are global phones though that work on GSM/WCDMA and CDMA. Verizon S3 can be used on GSM/CDMA, Sprint's S4 can be as well, etc..
Hi, everyone. I got my mother's lg g3 verizon phone when she passed away, and while I know that verizon phones are unlocked, I cannot use data with my French carrier. Verizon can't help, so I'm kinda sick. It's a much nicer phone than I can afford, so I really would like to use it. I think I have to change the APN settings, but I have no idea how, or what to change. Can anyone here help?
Hi! Please post questions in the Q&A section. I'll ask a moderator to move the thread.
I don't have any knowledge myself regarding changing APNs on the VS985, but it's possible that unlocking some of the other radio frequencies used might help too. I don't have personal experience with that either, but there are threads in this section having to do with that, maybe in Q&A too. Use the search field on both sections for "unlock" and you should find something.
I would guess that your first step is to make sure that the carrier you want to use it with uses any of the radio frequencies that are available on this variant. Some of the threads you find in the search results might list what all this phone supports, then you'd have to compare that to information about what your carrier uses.
This situation was dealing with the SM-G965U U.S. S9+
I recently had itekimei unlock two S9+'s. They were from xfinity mobile, which is CDMA.
The phone's work, but only on CDMA band carriers i.e. verizon, sprint. With GSM, only messaging and data work. Data barely.
Is it commonplace to be stuck with either GSM or CDMA frequency carriers after having professionally unlocked the network? Like if you had a locked T-mobile phone and had it unlocked, you'd be stuck on GSM correct?
Maybe this is a given and I am ignorant.
I didn't exactly check whether xfinity ran on cdma or gsm before I purchased them, so that was my fault, not itekimei. He's a great guy. Highly recommend him, as long as you have your radio systems correct.
Edit: I think I found the answer, and that is the U.S. S9+ is not cross compatible with GSM and CDMA. Please correct me if I am wrong and tell me how to make it happen if you know. Thank you.

The phone does work with GSM providers for calling, messaging and data. Check your preferred network type and select a different one. I replied to another thread you posted in with the setting I used that works.
Before unlocking my phone I had done an extensive amount of reading and research. If I was gonna pay for the unlock I wanted to make sure it would work for GSM networks. From what I can tell the G96U phone you have would be virtually identical to the one I have, with the exception of the carrier installed firmware. This is what would define the phone as Sprint or Xfinity. So if my phone works for calling, data and messaging on AT&T which is a GSM network then yours will too.
If needs be flash the U1 firmware to the phone as this would be the one that is on the unlocked S9 you can buy from Samsung. As a firmware for unlocked phones i believe it would be the most generically compatible with the providers for this scenario... well it's one of the reasons why I flashed it on my phone. The other is since I no longer use Sprint I dont need the Sprint bloatware.
There are tutorials on how to flash the G965U1 firmware to a g965U phone on this forum.
Also try keeping your inquiry to one thread instead of making multiple ones. Keeps all insights, discussions and etc in one spot and not multiple places.

Sorry, I had actually came back here to delete this thread after I thought about it before I read what you wrote. I was just at work my apologies. And thank you for correcting me. I will check out how to flash the U1.
