Putting thunderbolt sim chip in droid charge?

What will happen? Will the phone activate just like on AT&T? I know you cant switch back and forth with an iPhone since its all 3G CDMA etc... but will the sim chip change that? Can you hot swap?

It should, from what I heard, work like any other GSM phone.
So yea, your SIM should make you be able to make calls, text and data on the Charge.

Yes you are correct

You still must register the device in their system. However, once you do, its all activated.

Is there a reference, like a white paper or a tech spec that can actually answer this question? This Tbolt is not the first Verizon phone I've had with a SIM card, and just like this thing, they worked just fine without the thing. How do calling functions transfer with the card when it has nothing to do with the SIM card or LTE?

Per Verizon Website:
http://support.vzw.com/clc/faqs/VZAccess/4g_sim_card.html
Yes. You may activate any 4G LTE device that has been certified by Verizon Wireless to be compatible with our 4G LTE network, including devices not purchased directly from Verizon Wireless. Simply activate your 4G SIM card on a Verizon Wireless price plan.
I don't see anything that say you have to activate the device only the sim card.

I have done this numerous times. Just insert SIM and you can instantly make a test call.

[Q] No Service after unlock

I successfully unlocked my Samsung Galaxy S 4G. However when I insert an AT&T sim, I show full bars of signal but the screen says (No Service). I've tried two different sim cards and neither will work. They are both older sim cards but they should still work, right?
Only thing that stands out as odd is the AT&T APN isn't checked blue; it's white (unmarked?) and can't be selected. I'm using Gingerbread 2.3 and my T-Mobile card works fine. I have my network bands set to automatic.
And for the record, in order to connect to AT&T's network, I need to use the AT&T sim all the time, right? I won't be able to connect to AT&T when using the T-Mobile sim, yes?

Tmobile cam connect to AT&T only when data roaming for me if I got to arkansas... Im.at&t. But imma say to try to unlock again

When you switch Sim cards you have to do a factory data reset. Just enter recovery and select the option to factory reset then reboot it should recognize your new Sim.

I did a factory data reset from Settings->Privacy->Factory Data Reset and it didn't work. Still says No Service.
And I don't think I need to unlock again because when I access that one screen (I forget the code to enter) it shows all the locks as set to OFF.
Any other ideas why the AT&T SIM card won't allow my phone to connect? Is the fact that it's an old card the problem?

It could be the sim card although I really dont see how it could be. Is it a 3g sim card? If so it should still work, factory reset, input the at&t apn settings, reboot phone. That is what I would try, I have an unlocked phone as well, and once you input the unlock code, its UNLOCKED.

you would need to use your att sim card you may have a issue with the fact the sgs4g actually lacks 3g band
its hsdpa or edge or G
unless att uses the same spectrum as tmobile for hsdpa you prob will not get a signal

Thanks for the help everyone. In my newbishness, I didn't understand from the instructions on unlocking that the foreign SIM needed to be active. None of the instructions say it needs to be. That turned out to be the problem: I was using an old, inactive SIM (hence no service).
Sick as I am with T-Mobile, I just took my phone in to AT&T and switched providers yesterday.

Able to use 3G only without physical SIM card? Network debug menu?

Is there a way to use the phone without a SIM card? I don't have LTE in my area, and I keep getting the "no SIM Error" so was thinking that the SIM was useless anyways.
On the stock ROM every time I get the SIM error, or if I remove the SIM card itself, I get no data on the phone at all. When I try to turn on Mobile Data it prompts me to insert the SIM.
On other CUSTOM or JB ROMs, I don't get the SIM error prompt but I simply get no data.
On older Sprint phones, I know you can go into the DEBUG menu to see that EVDO/3G was actually being authenticated, the handshake was negotiated, then connection type/speed/tower/hand-off status, etc. Is there such an option with Verizon phones? I'm wondering if Data is completely shut off without the SIM, or if the data connection is actually established on the network but simply blocked from being used?
PS - per recommendation I have tried using the PHONE INFO app to switch the option to NV only, but am still getting no data. Voice/Text work perfectly.

ASFAIK, the SIM does 3g and 4g. WHY? because 3g on the gs3 is ehrdp and that also requires a handshake between 3g and lte. I believe it is like using 3g tech but with the pipeline size of lte... or thats as far as I've read into it.

Thanks for the info, xicewallx. I was afraid of that, however I've read of people flashing both Sprint and Verizon variants of the SGS3 to Boost, Straight Talk (CDMA), Verizon Pre-Paid which all I assume do not use LTE/SIM. I presume this means that the SGS3 can certainly use 3G without the need of the SIM card. I'm looking for a way to default to this on the SGS3 for us poor folk who do not have the luxury of LTE yet and have to deal with the SIM error until Verizon/Samsung fixes it.
Any help would be greatly appreciated!

I was able to get to a debug screen using the IOTHiddenMenu option (through Any Cut) but it simply stated that EVDO was in "sleep state." I wasn't able to figure out how to get it to start a connection yet.

So get a new phone? That one is obviously faulty. Go get a free replacement. You have to live with it for 2 years. I wouldn't want a faulty device for a week let alone 2 years.

Are you in a poor signal area? Only time I've received the "No Sim" error was at my parents where the signal is crap. As for using it without the sim card, doubt that's possible since the sim is used for authentication if I'm not mistaken.

hello,
if i understand correctly, the sim card in the S3 is basically the same as all the previous world phones, meaning its just RUIM card. The MEID and IMEI are on the phone, the card it comes with is just basically a storage device in simple terms. can someone who has access to another verizon active S3 sim try putting the card into their phone and checking the IMEI that the phone reports? does swapping the cards change the IMEI in other words. I do not think it will, but interested to know for sure.
i just started playing with one of these, but i feel realy confident you can get non 4G services to work without a sim in it.

You have it just about backwords. The sim is the real identifier on vzw 4g devices. You can take a working authorized sim and use it to activate another 4g Verizon phone and it will activate under the phone number associated with the sim.

There is still an ESN /MEID that the network uses to identify the phone for the CDMA side of the network. The process is all handled by the LTE SIM on LTE phones, though.
OP: You have a broken phone. The no-SIM error is not something that goes away. Take it to a store and get a new SIM and/or order a replacement.

im gonna have to dig in some more i am still not convinced the card is not a ruim card. like the other sprint and verizon world fones the imea is in the fone im pretty sure, until you instroduce another networks actual gsm card. i still the card it comes with is a simple ruim that holds the login info and other data, etc, well you know what ruim is.
does anyone have a service manual or white papers on this one yet? i would love to read through them.

I'm still looking for an answer to this if anyone has any suggestions. Any way to get 3G without a SIM card?

Did you ever get a new phone from Verizon? It seems like an issue with your phone, not the network.

I have been trying something similar along the way as I have been able to get rock solid data by switching to EvDo only using the Phone Info app.
I gave determined I am connecting to a US Cellular tower when I have solid data.
But while in EvDo only I cannot send or receive calls or texts.
I am looking for a way to enable calls and text while in EvDo only mode.
Not trying to highjack just thought this is somewhat related.

New phone and new SIM from Verizon seems to have made the problem less apparent, but it still happens, especially when driving through areas where reception is a bit spotty. It's really become an issue as I rely on getting emails for business, especially while traveling, and I don't get notifications of new emails if I have no data service which I don't become aware of until I actually look at the phone. Missed a couple of important emails/meeting invites because of this already...

I flashed a VZW GS3 to Sprint. 3G data is working fine w/o a SIM card. If I put a non activated VZW card, data doesn't work obviously.
The trick in getting this to work is to use QPST to configure Profile 0 and Profile 1. When flashing to Sprint or Boost, you must also load a Sprint PRL into the device using QPST.

[CLOSED][Q] Unlocked Relay getting no signal on a non-TMo carrier

EDIT: No feasible solution found, so I had the device sold. Question closed.
UPDATE ON THE ISSUE: It seems that it would not recognize WCDMA networks (GSM works properly), hence no signal on my WCDMA-only SIM card. Any ideas?
Hello all, new joining the Relay 4G forums
Long story short, so I got my Relay 4G today, but it just wouldn't fully recognize my China Unicom SIM card. Symptoms and information:
1) No signal
2) Correctly displays my carrier's name, but says "emergency calls only"
3) Can search for available carrier networks, including China Unicom, but fails to register on the network - it says "unable to connect, try later"
4) The device has a correct IMEI instead of a generic one
5) Doesn't prompt me to enter SIM UNLOCK CODE when I first plugged in the SIM card
6) SIM unlocking procedures posted in the forum doesn't help - the phone should be unlocked when I bought it
7) It recognizes another SIM card from China Mobile (WTF!!) and works properly
8 ) China Unicom uses the 2100MHz band, which is supported by Relay 4G
So now I'm out of ideas... Any help would be appreciated. Thanks

One question: why doesn't it prompt me to enter unlock code when I inserted the SIM?

@croogrog It didn't turn out to be that simple... SIM unlock procedures didn't work at all even though I got all the timings right. I think the problem isn't caused by SIM lock... But what can it be?

If other SIMs are working and you are able to call someone your phone was unlocked when you got it.
If your SIM isn't working it could be that you need a new one from your provider.
I had that problem years ago. My phone was too new ...or my card too old.

Best test would be to try another carrier sim all together. Not china unicom. See if the phone takes it. That way you will know for sure that it's unlocked and works. Unfortunately, there's no way to check if it's unlocked, other than to test sim cards
My next suggestion would be to consult samsung for a warranty repair, because your phone might be faulty. Or consider asking the seller that you got it from to send you another one. Let us know if you still need help

1. I checked with a China Mobile SIM and it works. Also, as said before, another China Unicom SIM also works. Only this specific SIM doesn't. It IS unlocked when I purchased it.
2. No way for a warranty - I'm in China and this is a T-Mobile USA device that many local "smartphone gurus" haven't even heard of, let alone "repairing" it.
3. The importer only has one such device in perfect condition (others have plenty of worn and torn), so exchanging is not possible...
I'm thinking of setting up an alternative solution for now...

More update on the issue: even on the China Unicom SIM that got recognized, it wouldn't connect to WCDMA/HSPA+ networks. Did an experiment: I used *#*#4636#*#* to adjust network modes, and when the device is on GSM only / GSM/WCDMA auto / WCDMA preferred, it would receive signal like normal; however, choosing WCDMA only, no signal is received. It seems like the real issue lies within the device after all...

If I understand correctly, the network mode menu option for WCDMA in the CM10 ROM is left over from the D2, which is a phone of similar spec which our developers based our ROM on. It doesn't do anything on the Relay.

But it DOES switch network modes... Or so I think, judging from the symptoms.
The first SIM only supports WCDMA(HSPA+), and when inserted, it can find my carrier's network but can't connect. On the second SIM which is compatible with both GSM/WCDMA, I lose signal only when "WCDMA only" is chosen, and under this situation the symptom is same as above. I assume that it can find my carrier's GSM network but not the WCDMA one.

[HOW-TO] Fix LTE for International Model Note 3 (USA Carrier)

So something weird has been happening since purchasing my mint conditioned note 3 on Sprint. Every time I was inside my home, my note 3 would lose LTE and stay on 3g. I was looking for answers and not finding a single thing. I came up with a solution myself and here is where the explaining begins. Be careful when purchasing a phone online as some are international phones (which we know). I happened to purchase an n900p note 3 model and it was actually made in China but my signal radios were set to Japan. If you are in the USA and using Sprint then do the following:
-Download from the play store an app called Samsung phone info
-After the install is complete open the app and open the menu on the left side
-Select Secret Codes
-Scroll down to settings and select Launch 0
-Choose Phone Information
-In the upper right hand corner there are 3 dots, choose radio baseband and select USA from Japan
-Enjoy LTE

Are you rooted? Or on the default ROM for your device? The problem could be sprint uses CDMA not GSM, GSM is for devices without sim cards but I think is used on sprint for the sole purpose of emergency calls

The phone might not be compatible with that specific carrier or you might have to take your sim card to the carrier and have them activate it but who knows.I took mine to Sprint and the guy asked me where I got the phone, I told him online. The problem with me having a Japan radio baseband set as default my LTE signal gets lost when I go in a building but when I'm outside, it picks back up again. If I switch the radio to USA I get 4g but then can't send/receive MMS. After a period of time on the USA baseband, it will completely lose signal and show up a black empty service in my status bar
