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.

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.

[Q] Can I simply switch SIM card to use Verizon S3 in Canada as a GSM dumb phone?

I am traveling to Canada, will use Rogers or other GSM network.
Can I simply switch sim card to use my phone on those network?
I only need to make phone call, and occasionally texting. I do NOT need data. I have seen people here discussion changing APN, are those discussion purely about how to use data?

I live in Canada, have a Verizon S3. I use it without switching sim cards without any problems. I do however have Canada calling on my plan. You can ad Canada to your plan for 15$ you'll get 1000 min I don't know about txt I'm on an old plan so it's somewhat different than what you might get. Try calling costumer service first b4 you go switching sims.

I am not on Verizon, I use this phone for Pageplus. This probably is not a option for me.

I just went to Ireland and was able to switch the sim and use it as a gsm phone. Only issue is, unless you have it rooted, you can't change the APN, so you'll get calls and texts fine, but you won't get data at all. If you Root your phone though, then you can dl some simple APN changing app that will allow you to put in whatever custom settings for whatever carrier your new sim is with. Hope that helps.

Thanks! This is exactly what I want.

Is There a CDMA On/Off Setting?

With GSM it's easy - you take out your SIM card, and you are off that SIM's network.
Presumably the Nexus 5 will work for voice and 3G without the SIM card. Is there some way to turn off CDMA (yes, I know that if there is no SIM I can just turn off all cellular data. But that's not my question.)

If you mean temporarily, you can always do the old standby of airplane mode. Enable airplane mode, then enable whatever wireless services you want (Wifi, Bluetooth). The airplane mode will keep the cellular modem completely off.

Now that the phone has been out in the wild for a while does anyone know the answer to this question?

The N5 does not allow voice or 3g without a sim for some reason. Perhaps someone will figure out a way to bypass this check at some point.
You can also pick and choose between gsm only, cdma only, lte only etc no problem.

I don't think it is compatible with any other CDMA only provider - certainly not with Verizon. Who else is there? Metro is going GSM/LTE.
Or perhaps the SIM is necessary to pick the CDMA provider - most CDMA phones are carreir specific, and they just default to the carrier associated with the phone. In other words, if you turn on an unactivated Sprint or Verizon phone, it automatically goes to the correct carrier. If the Nexus 5 has access to more than one CDMA carrier, perhaps the SIM is the method of selecting the carrier.

PagePlus is one who runs on Verizon and allows any phone. No LTE tho with them.
Also, The carrier on most CDMA phone is determined by the PRL file. This tells the phone which towers to communicate with and it can be changed.

Presumably then the PRL is preloaded on the Nexus 5 - hence it knows to look for Sprint.

They will activate any CDM phone for a except few exceptions such as if the phone is ESN banned on Verizon, PrePaid Verizon phones, Verizon iphones and Verizon blackberry devices. It's a well known unofficial policy.

Due to hearing that problem I might look at a S4 or something. I generally like the build quality of Samsung much better than LG.

I guess I really don't understand how CDMA works. With GSM, if the phone is unlocked, it works on any network. CDMA always seems to involve flashing. Although I believe there is so me sort of lock on CDMA phones as well (after all, MSL = Master Subsidy Lock.) I wonder if the CDMA side of the phone is locked to Sprint (we know from other posts there is an MSL code for these phones.)

In my experience, none of the *#*#xxxxx#*#* codes work without the SIM inserted. You might even need to be activated on Sprint at the time.

Just to clarify, CDMA in this thread includes WCDMA(3g) too?
So the phone will either go GSM or LTE only, which 3g or HSDPA/HSPA are not available by options?

[Q] If activated on Sprint, can switch back and forth to AT&T?

If the phone/uSIM is activated on Sprint and working, what happens if you put in another uSIM from AT&T (or T-Mobile) ?
Is only the AT&T (or T-Mobile) uSIM active and only voice data work with this new uSIM phone number?
I want to use this one phone to switch between Sprint and AT&T. As it sounds like the Sprint portion of the CDMA is activated without the uSIM.
I don't want a missmash of both with there is another AT&T sim in there..?
thanks

I'm not sure what you are really looking to do. But I have sprint and activated my phone on sprint. I then wanted to test out T-Mobile so I bought a prepaid sim starter kit. I just reactivated another phone on my sprint account and then popped in the T-Mobile sim and activated the phone on their network and it now it has the T-Mobile number and data services active.
Sent from my Nexus 5 using Tapatalk

So can you go between Sprint and T-Mobile service by, powering off the phone, inserting the different uSIM, powering on, then its 100% active CDMA/LTE or GSM/LTE?
I want to be be able to switch between Sprint and AT&T, by just swapping SIMs. I have read the uSIM isn't used in the authentication of the Nexu5 phone...?

Anyone else done this yet?
I'm curious as I read that you have register the phone on Sprint network aswell as using their SIM for LTE.
If using another non-Sprint SIM, is it still going to be on the Sprint network aswell as the non-Sprint network?

To activate and use data on sprint you need to have a sprint sim. Once activated if you take out the sim all you have is voice. If you put in an att/tmo sim it will automatically load up a default apn and connect. Sprint service is not available while the att sim is in place.
If using an mvno like straight talk just add or edit the apn to the correct settings.
When done with att pull the sim and put sprint back in. Reboot and you are back on sprint.

The sim is used but you have to call or chat to activate. Hopefully at some point sprint will end this part and just tie the sim to the account so we can swap between sprint phones without activation. Once activated yes you can swap between sprint, att and tmo simply by swapping sims.

Any sprint repair center should now have sims on hand and know what they are for.
Google voice integration for sprint is great for this type of thing. one number for multiple carriers on a single phone. nice...

Got it all working now, with both a Sprint SIM and an AT&T SIM.
The only downside is when I open hangouts, it asks me to verify/skip the phone number on each swap.
I mostly use AT&T for work, Sprint is my home cell that I hardly use.

Hi guys, for those of you that have activated on Sprint, does Sprint charge an activation fee ($36?) when you activate the Nexus 5 on your existing line? Thanks!

Yep, just call the international customer service, tell them you need a micro SIM for a nexus5.

I would think this would be such a major feature and selling point. A phone that can jump between almost all major carriers. I don't know of any other single phone that can do this?
