I generally understand how SIM cards work in the GSM world, but I am curious as to how it works within Verizon. I know Verizon uses both SIM/4G and CDMA in one phone.
So my question is, if anyone has two Thunderbolts handy:
Can you swap the SIM cards between the two units and will the phone number and data usage STAY with the SIM? Or will the phone number STAY and the data usage MOVE with the SIM? Or some other variant? Or will you need to get a new SIM and/or call Verizon to reactivate the SIM when you move it?
AND, are you swapping between two Thunderbolts on the same account or different accounts?
Thanks.
Verizon told me it works just like GSM.

From my experience yesterday with swapping my dinc and bolt numbers you can not swap cards. Had to get a new sim card to swap numbers.
SIM card is assigned to your phone number, and not to the phone itself. If you exchange your phone, but you keep your phone number, you can use the same Sim with new phone. If you put your Sim into a different phone with different phone number, even on the same account, and even it would be a TB, it would not work.
I only believe half of what comes out of a VZW CSR and about 10% that comes from a sale rep at a VZW store.
Looking for hard examples.

I'm confused. At first you say the SIM is assigned to your phone number and not the phone. Later on you say the SIM in another phone with a different number, does not work.
"If you put your Sim into a different phone with different phone number"???
You can only have 1 SIM card in a thunderbolt at a time. Are you speaking from experience or is this what VZW told you?

Never said dinc has a Sim card. In order for me to change the number on the TBolt i had to get a new Sim card. So you can't swap cards like gsm.

Why does being unable to change your number without getting a new sim mean you can't swap the sim card into a different phone.
You can move your sim into whichever phone you choose, which as of now would be from one tbolt to another tbolt, no need to call verizon or anything. You will be able to simply move your sim from tbolt to the samsung droid charge or the bionic when they come out if you wish.
Actually you can swap the sim cards between phones, I have done it. The reason you had to call was to activate your number on the sim.

The phone number is tied to the SIM like GSM. I got a replacement shipped to me and swapping the SIM back and forth did all the activating.
When I got a new droid shipped to me I always had to call and tell them the MEID of my new phone before it would activate.
So, when you stick your SIM in another phone, that phone get's your phone number, data, etc. the same as a GSM phone.

When you change the phone, you are "taking" your phone number from old one to the new one. Then, you don't need a new sim card, cus you still have the same phone number on your new phone. But, lest say, your friend has TB as well....if you put your sim into his phone (and vice versa), your sim will not be working. (it won't recognise his ph number as yours - the one it has been assigned to).

Yeah, true!! But you have the same phone number on you new/next handset, right?
I switched from T-Mobile and a Nexus S to a TB hoping that the SIM card swapping works the same. A couple year ago Verizon had a press release about being more open to devices so I hope that it means the same deal as I used to be able to pop my SIM card to any upcoming LTE phone

No, T-Mo is a GSM, and VZW is CDMA. Verizon SIM is only for DATA.

Yesterday i called *611 CS and tried to swap numbers between my dinc and tbolt. He did in fact switch numbers but the sim in the tbolt was deactivated. He might have screwed up something but told me he could send me a new one or i can take it to a verizon store. I was still able to make calls with the tbold but didnt have any data until they program a new sim card.
Missed this one. Thanks for responding directly to my question.
My last question is, can you swap it between different accounts? The phone sent to you was to be activated on your account. Can you take any strangers phone and SIM swap?

is the thunderbolt the same as older SIM card phones? where if a phone is stolen it cannot be deactivated? i understand that in order to activate a SIM card you have to also supply the esn number of the phone it will be paired with. but down the line when there are more LTE phones out, if someone had an activated SIM card, could they place it into a stolen phone to use it? or is there a way to blacklist a phone even if it uses a SIM card?
Are you saying that you have a stolen phone or is this just for knowing?
Take this with a grain of salt but the Verizon reps told me the SIM cards are not swappable with the LTE network. I've exchanged my phone 3 times now and they have to give a new SIM each time. They shred the old SIM.
They lied to you. I have exchanged phones never changing the sim.
Not for me 2 phones same sim, no issues here.

Perhaps all of the LTE SIM cards are the same, and the only authorization is done through the ESN code like it always has been. That way, if someone loses their SIM card (how?) it wouldn't be a big deal, and if they lose their phone, it could still be given a bad ESN and not let anyone else register it.

i was just wondering how it worked in comparison to the SIM card on other networks i had used in the past. when i was with T-mo i know they couldnt lock down a phone like verizon can since they where on SIM cards. so was just wondering if that was the case for our phones now that we have SIM cards?

Just my two cents here. There is definitely an place in the Phone Identity portion of the settings menu that states the SIM Card ID, IMEI, and MEID. It seems to me that this would make it so you can still swap devices without extra hassle, but VZW should still be able to blacklist phones reported stolen via the MEID. I could be wrong, this just seems to be the case to me.
The sim card activates the phone, upon activating it communicates with verizon database. Pure and simple verizon can and will track the MEID and if the phone is stolen or in non pay table then it won't activate. Try it out, then your tbolt off and turn it back on. The first 10 seconds upon boot you won't have signal or data. Then it comes on. It's like the same as a prl update *228. Anyways I'm getting off track here's the deal. Your phone has a seperate entity from your sim card. Both need to be clear to activate.

This is true. If you have the Thunderbolt and the Charge or any other VZW 4G LTE phone you are able to swap the sim back and forth.
you only have to replace the sim card if you cahnge your number or activate the device he sim can only be used with 1 phone number. The serial number of the sim card and the ESN of the phone both must match in the VZW system or it will not connect to the towers. I have to replace them all the time. So no you could not use a lost,stolen, or non payment phone on the network, phone still essentially a paper weight or spare parts.
I was under the impression that the sim was only applicable to LTE-level functions. The phone's main functionality is still mostly CDMA based and those functions can still be shut down if the phone is stolen. To my understanding, simply inserting the sim card into the tbolt does not just activate and associate the phone to your account. There's still an operator you have to call, right? With Tmo and att, inserting a sim card activated the phone without calling someone or going into a store.
The SIM is a RUIM which eliminates the need for an ESN swap the the best of my knowledge. I started with a LG VL600 air card and then got a thunderbolt. I was issued a new card at that time but I can swap between devices and it works without a problem. Once June 15th I fully expect this to stop working.
Given the TBolt has the sim card, it seems it would be a little crazy to switch back and forth (if not impossible). This issue was touched a while ago, but is there an easier way yet? I guess anytime you wanted to switch back to the tBolt you needed to get a new SIM card. Is this still the case? Or can you use the website to switch back and forth between phones.
Reason I am asking is that I would like to use the iPhone during my work day since all of our machines are Apple based... and tBolt any other time. It just doesn't seem possible unless something changed?
I was also wondering how this would work. I have several phones and, until recently when I got my Tbolt, would switch between them quite often. Now with my first 4G phone, I wasn't sure that would work. From your post, it sounds like I could go online and switch from my Bolt to one of my 3g devices as I always have, but going back to the 4g Bolt might be a problem? I don't have 4g in my area, but I really am liking my bolt and don't feel the itch to switch devices yet, but I would like to be able to have the option.
Why not just call VZW and ask ?
That would be the easy way to answer your question.

They give different answers each time you call! Depends who you talk to.
if it helps, sim cards are sim cards and the one in the tb (though it works in a slightly different way than what would be normal for a sim) is the same as any other sim card. However, if you switch to activating a 3g phone without a sim card, they will deactivate your tb sim card for sure. They may even if you don't, just because they're verizon and are slightly clueless on how sim cards work still.

Can you ever switch phones online without calling Verizon. I have never been able to do it other than when setting up maybe a new phone but never switching back to an old one. Good luck though it would be nice to be able to freely switch. I have a DInc and OG Droid just sitting here

Switching from 4g to 3g phones you have to call in each time
Sent from my Transformer TF101 using XDA Premium App
I have tried switching from 3g phone to 4g phone and it is a pain. You need to call or go into the store and get a new sim card each time. The minute you place a 3g device on your 4g account the sim card is deactivated.
I switch back and forth now because i talked the store manager into giving me a few sim cards. You can also call every other day and have the customer service send you a new one. They are free but some stores will try to charge you.
Once you have the sim card all you need to do is turn off the 3g phone, place the new sim card in and it should activate itself.
Wow thats pretty sad that its this difficult.
I had tried this once and it brought up a question that I did not have the guts to answer myself. If you went back to 3g for a short while then afterwards reactivated on 4g would you loose the grandfathered unlimited data?

Just talked to a VZW rep on the phone, who I'm assuming went to talk to a supervisor or a tech, and she said as long as I keep the sim card in a place where the gold contacts don't get harmed (like in the phone), then I can keep the same sim card between activations, I just have to either call in to switch back to the TB or activate it online.. She talked to someone about this after I asked if I could have a few sent to me, so I'm assuming whomever told her this at least had some knowledge on the situation, but I guess we'll find out when it's time to switch back

the verizon rep that told you you can keep the sim card between activations is wrong. The sim card for verizon doesnt store any data its just basically a key to there 4g service. They can only be used for one activation and once they are deactivated they are dead. The only way to switch back and forth would be to have a surplus of sim cards. You would still have to call in and have them activate the new sim card before using it.
Ii have done this a few times on my thunderbolt so I know from experience.
Not sure on that having multiple SIM cards is right. I have switched between my DX and Tbolt numerous times and never gotten a new sim card. I do have to call every time when reactivating the bolt though.

I can't see how this would work since LTE and gsm cards aren't compatible. If you could do that, you could drop it in most of the decent BlackBerrys and run... But ya can't. Anyone telling you that you can isn't at all familiar with the specs.
What a pain in the butt.
Sent from my GT-P7510 using Tapatalk
just my experience...
Using the My Account web site, I can...
Change between multiple 3G phones, no problems.
Change from 4G/LTE phone to 3G phone, no problems other than... the Web site warns the LTE SIM will be disabled after 90 days of non-use, implying that you could re-use it for up to 90 days, BUT the SIM gets deactivated immediately.
If I try to change from 3G phone to 4G/LTE phone, no problems IF I have a NEW SIM card. If I try to re-use my SIM it fails and I need to call in. When I call in, its hit or miss if they can enter that same SIM back into the System (customer service can't, but tech support has done it) or make me get a new SIM.
I haven't tried switching in about 3 weeks. So I don't know if anything has changed since.
Also, I find it best to complete the equipment change before 11pm eastern, otherwise the device change could get hung up in VZW's switch/system and not complete/clear until the morning.

At this time, it is still necessry to relace the SIM card if changing from a 4G device to a 3G device. So, if you were to change devices each day, you would need a new SIM card each time. Please check out our forums for updates at our website. Go to the website for Verizon Wireless, click Contact Us, then Customer Forums. You can also sign up for email updates from this site.

verizon actually semi pays attention to xda
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.

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.

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.

Hey all! Long time lurker, first time poster. Is anyone working on running the Nexus 5 on multiple networks? Specifically, Sprint and Tmobile?
I don't see why this wouldn't work right off the bat. In my head, the radios are present and sprint uses the imei number instead of a Sim card. So shouldn't it work similar to a dual Sim phone?
My hope is to keep my $30 T-Mobile plan and add FreedomPop as my source for free minutes when in a sprint area.
I'd love to hear from everyone, my searching couldn't find anything but if your googlefu is better than mine please help!
Thanks,
Matt

I never thought about this before but now that you mention it, it could be pretty cool to have access to two LTE networks if one of them is being slow. Sprint want a ICC security SIM card in the phone though, not sure if you could bypass this or use the phone without it anyway.
You need a sim card for spring LTE and voice/data on T-Mobile, and there is only one sim slot.

Thanks for the quick replies guys! I'm still very interested in it, perhaps you are right that the security Sim could be bypassed. I'd love this to gain some traction, this would be an incredibly unique feature to boast!
The phone doesn't have dual radios to even accommodate this anyway. So even if you were somehow able to activate it with a TMO SIM and on Sprint (which alone would take a ton of ROM hacking), you still physically couldn't talk to both networks. The radio would need to pick one or the other. It can't just flip flop at will, it has to set up the connection with the tower and maintain it.
I disagree. If you were to activate it on sprint, you could use it without the sprint Sim... You just would not get LTE. So technically you could activate it on Sprint (as you don't activate the phone on T-Mobile just the sim).
It would be cool if we could bypass the sprint Sim necessity.

This won't work because when connected to LTE on Sprint it uses eCSFB to fall back to 1x to accept the call. This happens over the LTE connection. If you're connected to tmobile LTE, there's no way for it to tell you you have a call incoming from Sprint's network.

So do you think it could feasibly work as a simple menu option choice, or a widget to switch networks? I personally use Google Voice so receiving calls would happen in whichever network happens to be connected

No, you actually have to switch the SIM. Once it's registered to Sprint with a SIM, then swapping that SIM for another carrier's SIM completely switches it over. Then, when you want to use Sprint again, you put your Sprint SIM back.

I guess what terky meant is he will forward calls to two numbers in Google voice settings ( let's say T-Mobile and freedompop) and then whichever network will be active will receive the call. So you will still be receiving the call.
Sounds logical but it has to be tried.
I see freedompop's website now accepts meid numbers. But my concern is; will activating the nexus 5's meid number on freedompop block using the gsm functionality of the phone??
If not, it would be just terrific!!

So with the new Android 5.1 update, which now supports dual sim, (I know guys N5 only has one sim card slot) do you think it would be easier to do this?
My idea is to get a freedompop service with the imei number, just registering the phone online and you dont physically need a sim card from them. And lets say we use another sim card ( Att, tmob, etc) to use. So basically we would have two service providers.
And from my point of view; i wouldnt need both of their services at the same time. Lets say i want to use freedompop first, and whenever it expires, I can switch to my other carrier manually.
Any thoughts on this?
Brainstorming?!?!?!
