Question on 4g SIM card. - Verizon LG G3

So I just learned that I don't need Verizon to activate my phone, I can simply swap the 4g SIM card from my s5.
My question is, does everything work when I do that? 3g and everything?

it should work just fine. i swap cards all the time

Everything should work exactly the same. I switch between sims through the Verizon site(different size Sims on phones)_ with no issues. When you put the new Sim in restart device then it should load up with the number on your current Sim and everything should work perfect

question about phone's antenna.

hi guys, i've been having a problem about my network. sometimes my data isn't working at all but it doesn't really says that it's disconnected to fix it i have to reboot. I tried different roms but my data still drops sometimes like 4 times a day.
so is there any chance that i broked the phone's data antenna even my calls still work? i have the phone for 6 months and this is the first time this has happened. i really don't want to exchange my phone to tmobile but if that's the only way to try then that's what i'll do.

I would suggest getting a new SIM card. In most cases a new sim card will fix that problem. I work for T-Mo and that's usually a good fix. If that doesnt work then try a factory reset. If that doesn't work then warranty. Good luck!!

yeah i have done a factory reset. So i'll ask t mobile for a new sim card?
Sent from my SGH-T959 using XDA App
Just go to a store and ask for a sim replacement. Since its a damaged sim they should just replace it for free.

I don't need to call them? i'll just directly go to a tmobile?

Yes sir. They will activate your number on to it and put it in the phone. Off you go. That simple.

When you bought your Vibrant, check in the box, there should be 2 sim cards.
i just called t mobile today and they said that my sim card is old which is weird. my sim card came with the phone 6 months ago. is there really a new sim card?
So they said i do need to change my sim card, will my number be changed?

If he upgraded to the vibrant and the rep happened to leave the sim in there then there would be another one. There is typically only one sim per box.Usually if you are an existing customer and you upgrade the rep will take the sim out of the box and keep it.

Nope. Number will stay the same. They just activate the new card with your number and deactivate the old. Yes, they came out with a new version of the sim card a while ago.

oh ok thanks. i really forgot to ask why did they put this sim if it's not compatible with the phone. I didn't know that they have a newer sim card.
thanks!

Well the one that you have should work fine. But like anything else they occasionally go bad. They updated the sims when they started upgrading the network. Just gives a better connection on 3g/4g.

[Q] Switching between LTE phones

If I wanted to switch from one verizon 4G phone to another, do I have to call and switch the ESN/IMEI or will just swapping sim cards be enough?

Just swap SIMs.
Ive been wondering this. Lets say my phone gets stolen, can I still call verizon and have them lock the phone as stolen or can someone just stick their sim card in and works?

you can get the phone blacklisted.

it would get black listed but they would have no trouble sticking any GSM network sim in it.

I don't think verizon has fully transitioned over to black list imei numbers to fully block them from being used on the network.

Can you switch sim cards on Verizon network?

So if your rooted and unlocked can you simply switch a Verizon sim card for a Verizon sim card? Like my wife's unlimited data razr sim in place of mine?

I'd say yes. When I got the note, I just pulled the sim from my rezound and put it in the note (had to cut it down to size first). No need to call Verizon for anything.
Yes I did that stock with no problems before I unlocked
Sent from my SCH-I605
Another yes here. Pull the sim out of my galaxy nexus into the note 2 and had no issue. Even updated my account on Verizon within about 5 minutes
Sent from my SCH-I605 using xda premium
This is cool. One thing I always liked on gsm carriers is the ability to swap phones whenever I wanted and as much as I wanted (work phone/play phone). What would really be cool is if could put my Verizon sim in my unlocked nexus 4.........
What if the Verizon note 2 had a bad esn? Would it still work I see a lot of deals on ebay for around 4 hundred!

Nope, once it has a bad enough it can't connect to the network anymore, those aren't worth 400.
Edit: I'm not sure if you can unlock it and put it on another network, but it won't work on Verizon.

AT&T Sim Cards are back w/Straight Talk!

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.
Sent from my SCH-I545 using xda app-developers app
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?

Sim Card Issues

I recently purchased a note 3 and I didn't have a sprint sim for it. I ordered one and inserted it but I still get the notification "No SIM". I've rebooted the phone and checked to make sure the SIM Card is in correctly. What do I do.
Sent from my SCH-I605 using XDA Premium HD app
Either your SIM is bad or your reader may be faulty. I know sellers like to sell phones without the SIM in it to hide a failed SIM reader.
Sent from my SPH-L720 using XDA Free mobile app
I'm fairly sure the SIM Card Reader is functional because I put a Verizon sim in originally to try to remove the notification. I will switch the Sims for my note 3 and 2. To find out if my sprint sim is faulty. I'm doubtful but best to check
Sent from my SCH-I605 using XDA Premium HD app
OK just checked the sprint sim card is functional as I get a non Verizon sim notification in my note 2 and when I put the Verizon sim in the note 3 I get invalid sim so this means the sim reader is functional on the note 3 and the sprint sim card is usable. What's going on then

I'd still try another Sprint SIM. When you get the replacement one MAKE SURE TO TELL THEM IT'S FOR A NOTE 3!!! As far as I know, there's different SIM cards for different devices. A SIM from an iphone 4s won't work in a Note 3.

Even if it's programmed for the same number?
I can give you the link for the sim I got. As far as I know it's the only sprint sim out there that I could find. Would It be possible to flash the note 3 to Verizon, At&t, or T mobile. If it would be easier than getting a new sim.

As far as I know, it doesn't matter. I could be wrong. But from my experience the SIM model number does matter. The model number varies amongst the various Sprint devices and I recall what worked for one phone didn't work for another.

So wait....you're trying to flash? It's unable to be unlocked to GSM. If you flash the device you don't need the SIM. The SIM is ONLY for 4g LTE. If you flash you won't get LTE, and therefore you don't need the SIM and anyone who tells you otherwise doesn't know how to flash the baseband.

Huh?
You lost me. I just want the notification gone. I'm trying to use the note 3 as a media device not a phone as of now. If I could flash it might remove my error. I don't know if it's even possible. Not worried about the LTE till late when I may or may not use the note 3 as a phone. Data charges get me. But if there's a way to fix the sim issue with no flash that would be ideal. But if not its alright I can probably flash or try order yet another sim. Or try to find another solution.

OK just read that again I understand now so no sim
Sent from my SCH-I605 using XDA Premium HD app
I think someone found out how to remove the no sim notification by editing something in the build.prop. But honestly, it doesn't even do anything. You can still use the phone on Wi-Fi and you can get it flashed to use talk/text/mms/3g.

You'd need to root the phone and get some kind of file explorer. It's not that hard. The most difficult part will be finding what to edit/add to the build.prop file.
Throw the Sprint sim in the trash...or burn it.

I had a problem with the SIM card from a Note 3 that I bought on Swappa. My problem was that my phone would not switch to 4G LTE. It gave me some EHRPD error and occasionally a no SIM card found error.
The way I fixed this is I wrote down the serial number off the card itself then contacted Sprint via chat support. The number on the card was different than the number Sprint had assigned to my phone. They changed the number to the number of the card I had, rebooted my phone and the problem was fixed. Now I have 4G LTE and no longer get a no SIM card detected error.
I suggest writing down the number from your card, contact Sprint via chat and have them change the number of your card to your phone. That might fix it for you. How this helps!
Why not just take a trip to the Sprint store. They should be able to fix your issue.
