I have a strange problem. I bought a Verizon LG G3 from someone and I put my att straight talk sim card in it after verifying with verizon that the imei is clean. It works fine until you restart it then it has no service. It will still have global selected as well as the apn setting I entered. If I make it manually search for networks AT&T shows up but when I click on it to register it to ATT service after a long delay it says it cannot. Also if I select cdma there is no verizon signal either which it had before. If I factory reset it, it will work once more until I power it off and restart it. I've tried clearing the cache partition as well as updating from kitkat to lollipop. Same problem. I have it set up the way I like it now and really don't want to factory reset everytime my battery goes dead. Any ideas??? Thanks in advance, Mike
Another thing I noticed is there is a sim card icon at the top with a ? in it. It is there even when the phone is working.

After updating to lollipop it wont even register on the att network after a factory reset. I flaahed back to 4.4.2 with lg flashtools and still nothing. Also rooted and then installed snapdragon rom and no luck either. Any ideas anyone?

Get a straight talk verizon sim that way it works perfectly and you will get 4G LTE.
They sell kits at walmart just make sure you get the CDMA 4GLTE kit
Verizon doesn't have good service here. The phone also doesnt show verizon signal anymore like it used to.

Straight talkvzw is the best in my opinoin but if you must have ST Att then I suggest trying a different sim. You have to use a 4G SIM in it so if you don't have a 4g Att SIM it won't work. After you get the SIM make sure you activate it then switch to gsm mode under mobile network settings. Then download the straight talk data settings app from the play store and follow the instructions.
GSM mode: settings/ tethering and networks/ mobile network / network type : global>gsm

Yesterday I bought an i717, an unlock code so I can get it working on T-Mobile, and put the newest Cyanogenmod nightly on it.
I noticed that my data speed was stuck on Edge and found out with some searching that this was common problem. I went to this thread and have followed it's instructions but now I've hit a wall and can't figure it out.
I've flashed both the radios that should work but am getting no working results. Can anyone offer me a hand with this? I would greatly appreciate it.
I don't have T-Mobile but suggest try different ROM. Also make sure have most recent twrp

I'll give that a shot, thanks
Thanks for the reply. I tried all that, new TWRP and all kinds of different ROMs but the problem persists. I did notice one thing however, and that was when the phone had the ROM flashed on it, brand new (like just after a factory reset), 4G worked really well. That is up until I turned the wifi on. Turning the wifi back off, and/or restarting, and/or clearing cache and dalvik will not get the 4G connection back. I'm at a loss. Also if I try flashing a different radio I'll have the disappearing APN problem. So for now I'm stuck with EDGE.
What other options could fix this? Could the build prop be making a fuss? I don't really know where to go.
It sounds like your sim isn't a 4g provisioned sim. The APN would stick if the sim was appropriate.

Tho I guess a new SIM card could be worth a shot.
This is "The Answer Post"
I got it! It was in the mobile network options. Since this is an ATT phone with an ATT radio I had to think a little differently, since I'm used to T-Mobile settings. The "Data Roaming" and "National Data Roaming" check boxes were unchecked. Again, being an ATT radio I guessed that these needed to be on. Once doing that I went down to network operators to manually select "T-Mobile" as my network. Once I did, voila! 4G connectivity now works like a charm.
Just wanted to let the internet know, in case someone else needs this.
Good save!
Ok so I (foolishly) bought a galaxy s4 with verizon even though I was moving overseas to Israel in two months. I made sure that the phone was world capable (like it can do cdma and gsm) and the guy at the store said it would handle foreign sims no problem. Once I arrived here I got a new sim. I figured out that it needed to be in gsm. From then on it had the service bar and confirmed it was connected to Orange. Since then I have been able to receive calls and texts, but not make them, every time I try to make a call before one ring I get a prerecorded message saying that my number cant be completed as dialed. I have tried several things already to fix this: to a cell phone repair person, to the local sim carrier where a lady tried using the sim of her own phone, customer service at verizon and samsung (who both told me to go see the other). I also did a factory reset which didnt do anything.
my phone is not rooted and is schi545 ME7. I will root if I have to, but if I dont I would prefer not to for the time being
Anyway I suspect the problem has something to do with the fact that I got the phone from verizon. Every time I start the phone I get the Verizon logo and after a minute I get a notification from the verizon set up wizard saying that I have a non verizon sim and that the sims source is unknown. I also tried disabling the verizon security and was able to make the notification go away but the problem persists.
Can someone with experience with this kind of stuff help me please? Thank you so very much:good:
Are you sim unlocked? I don't think the phone is unlocked. Talk to verizon to see if they'll unlock it.
According to verizon I am. I spoke with multiple representives from verizon and they said the phone was unlocked

Has any one told you if you have to change any apn, access point name? That may be the problem too. They can be specific to the carrier.
No, how do you configure that

all LTE Verizon phones after Galaxy Note 2 are factory unlocked it must be a APN issue. Try maybe to do a factory reset and as previous poster suggested do the steps he told you to change the APN or look into I think it's called HiApn in Play Store.
Also try to put it in global mode or GSM? play with the settings.
still having problems
Thanks for all the input everyone but my problem still persists
I downloaded HiApn and followed its instructions to which told me to set up 3 Apns. I noticed that only one of them can be active at the time. I tried with each one active and I still can not make phone calls. Does anyone have any other ideas?

Go to Setting, call setting, disable the prefix international. I have done the same for using Verizon S4 in Indonesia.
Mine was not unlocked either, although I knew this before buying. This is a guide I tried (without success) to unlock it on my own.
Like the last poster, I reside in Indonesia, but I was never with Verizon. I rooted mine and have had no problems since.
Ok so I went to call settings and the closest I found was assisted dialing for international calls and the option to turn it on or off. I played with that for a bit and it didnt work.
I also tried the code and it said connection problem or invalid code
during my fiddling I came upon an app that showed promise of fixing my problem if I had adb shell. Does anyone have a good place to get that? I tried a few that didnt work out for me. There was another that showed promise but it wouldnt send a package no matter what I try
Thanks
If you want ADB, you need to download Android SDK and have Java Runtime Environment also installed. Then, it is just a matter of typing in "adb" into the command prompt of Windows.
Is there a serious conflict for you not rooting the device? The true benefit of doing this is to get SIM cards from anywhere to work, and to allow certain apps to work. Rooting is simply a matter of bypassing security parameters. As long as you follow instructions strictly, you won't have an issue using the phone as it should be used.
yea I suppose I could try to root it. Im just not great at that stuff and am worried about messing up my phone permanately

You don't need to root. You need to sim unlock. Get a hold of att international chat and adj them for an unlock code.
Hey guys thanks for all the help but I figured out that it was just a bad sim all along and that the first school screwed me over
But everything works now
I recently rooted my phone with Casual's method. Everything went smooth on the flash.
Except I am unable to activate the phone through the verizon *228 method.
when I dial *228 it just says physically on the phone "A Verizon Sim card has activated your service and updated your phones roaming capability"
but then I got to call someone and it says I have no service.
I also transferred my service to my old Droid X while I did the rooting just in case that has anything to do with it.
Someone please help, at this point im about to return it to stock.

*228 is for 3G devices that have no sim. Thats what Ive been told and what ive experienced. Now you said no service, are you getting any bars or is it no bars at all. Have you tried going to mobile setting and toggling lte/3g mode. Also have your tried the hidden setting either by dialer and changing lte/gms/3g modes and then going back. Sometimes it may get stuck in a radio mode that doesnt get signal like in gms mode. I had been in the same situation and fixed it by doing the above.
New Sim card probably. That's your best bet
Sent from my SCH-I605 using Tapatalk 2
*228 is only for CDMA devices only, not CDMA/LTE. Your problem is that you activated a non-SIM device on your account after having a SIM device active. Doing so de-activated your SIM card, so you're going to have to go to a VZW store, or call VZW to get a new SIM to have service on your phone again.
Hey guys, recently switched to AT&T from verizon 2 months ago. The guy at AT&T typed in the APNs and all is good besides poor reception at my house. Last night i turned off mobile data to see if my reception to send a text got better. Now I cant get mobile data to turn back on... It says add mobile service please contact customer service and gives the verizon customer service number. Any ideas on how i can get it back on? I've tried everything i can think of besides activating it on verizon again....
You might need to manually enter your APN since this is a Verizon device running on AT&T. Also if you are using an AT&T SIM you might need to input an IMEI for AT&T to get back on. These are the issues you run into trying to use CDMA/Unlock phone for one carrier (unlocked does not mean full functionality on all networks, if that was the case there would be only a single model of the V10) on a GSM carrier.

I did manually enter the APN... It senses not connected to VZW and then says to call VZW customer service... might have to activate on verizon again turn on data and switch sim?
The same exact thing happened to me a month ago
Go to: Settings>Backup & Reset>Network Settings Reset
it will turn your data back on by default but you might have to put your APN info back in
hope this helps
youre amazing!
I know with the op n200 metro version you could put your T-Mobile sim in and unlock the phone to work with TMobile automatically, I can't find confirmation anywhere if this works with the n20 as well, does anyone here know?

Was the n20 brand new and the T-Mobile sim inserted before turning the phone on the first time? I read that's how it works on some older phones, I think metro blocked it finally but was hoping it might still work.

yes, I received the phone in mail this afternoon, Brand new and first boot was with T-mobile sim, no service and Mobile network status showed "Disconnected"
The Boot animation did change to T-mobile on a reboot with the sim inside but still no service
As I was playing around with the phone, I stumbled upon a weird way to get signal by trial and error got 4G and 5G data as well but when Wi-fi connected, data seems to switch back to 2G. Let me know if you want to know how

Sure, here it is:
1. Boot the phone with T-mo sim inside the device, once booted you wouldn't have any signal
2. Go to "Sim info & settings" > "Preferred network type" and choose "2G/3G(Automatic)"
3. Reboot the device, once booted you should see signal along with 2G icon
4. Now go back to "Preferred network type" and select "2G/3G/LTE(Automatic)", you should now have 4G (Texts and data works but call dropped)
5. Now switch to "2G/3G/LTE.5G(Automatic)", you should see 5G network (Texts, calls and data all worked fine)
5G was stable for several hours until I connected to Wi-fi and when I disconnected Wi-fi, I noticed that data said 2G.
Let me know if the above steps worked for you

Did you get an incompatible SIM error, or just no signal? Also, you can't just put a Metro SIM in a phone and have it work. You have to call them and tie the IMEI of the phone.

OP is talking about the other way around, T-mo sim in a Metro device
Nord N200 had a bug where the device could be locked to Metro but worked flawless with T-mo sim.
That bug being patched is what OP meant by "blocked"

Yeah, I got that backwards. But if he's not getting an incompatible SIM error with a T-Mobile SIM in the MetroPCS phone and actually getting an edge signal, maybe add a new T-Mobile APN profile. Should work in theory.

Thanks! Good find! Yes I was able to reproduce the behavior. Also in my case it seems that the 5G/LTE will revert back to 2g after some idle time. But I can use the airplane mode to repeat the process (without rebooting the phone) to repeat the process. I was able to reproduce on another metro phone as well. must be some kind of loop hole.

I know I already mentioned this, but did you try making a new T-Mobile APN profile and deleting the old one(s)? Maybe you wouldn't have to go through that ritual. might work, or not.

I take it you're not a MetroPCS customer. Must be something baked into the OS. I wonder if it still has the MetroPCS bloatware since it booted with T-Mobile boot animation? Anyway, there are services on eBay that will unlock this phone through the MetroPCS unlock app. I'm not selling anything just letting you know that's an option if you didn't already know.

It installed the T-mo bloatware and removed metro bloatware as soon as it booted. Yeah, I'm not a Metro customer, I'll usually just leave it alone for 180 days and unlock it afterwards

Ah, but you need active service on it for those 180 days to be eligible to unlock it no? And now that it has T-Mobile firmware how can you unlock it from Metro? I'd download the MetroPCS unlock app from the play store and run it to see what it says.

In theory, it's 180 days of active service but in reality, they've been unlocking 180 days after activation. I pay for first month and then throw it back in the box.
Also, I didn't see the unlock app as part of bloatware, its built into settings > about. It'll pull up the same screen as in Unlock app and we can try to unlock from there but obviously, throws the error showing it needs 180 days of service to unlock and is not eligible currently

On eBay it's 75 bucks to unlock. Thats like 2 months of service and you'd be able to use it in a few days instead of having a paperweight for 6 months. Thats what I did on my old Moto One 5G Ace.
