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'm also on my 3rd Thunderbolt and still have the same SIM card I got on launch day.

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?

yes, im wondering if this is the case? really im just curious if i lose my phone or it gets stolen. is it a paper weight once i report it? or is it up for sale to anyone with an activated SIM card?
3 phones same SIM for me...

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.
Anyone else experience issues with swapping their SIM from their old phone into the G2X? I have reseated mine from my N1 into the phone 3 times, and each time I boot it says I have no SIM card. Pulling my hair out!
I went from an N1 to the g2x and i had the same problem so here is the deal...
the g2x is a 4g phone and it required a new sim card version so i had to trade in the sim card that i have had since my i got my razr in 2005...
so disclaimer to anyone who buys the phone outright, you have to have an updated sim card... just go into tmobile and they will give you one...
mines wont check for sim card at all it keep saying no service even without a sim card it usually say no sim but it just say no service can someone help plz plz plz
Fyi make sure it is a corporate store. Otherwise it could cost ya $20. Customer care might even be able to mail you one...not sure. If your near Chicago I would just give you one of my extras.

I reused the sim from my N1 and have had no issues but it was probably a newer version sim since I just got it beginning of last year.
If you have an old T-Mobile phone lying around, try inserting your SIM into that, and using it, then re-insert it into your G2X.
Alright I opened it up and it looked like the antenna cable was a bit frayed near the tip, I attached a few pics. It was connected though so not sure :/

I have the same issue.
Mint condition G2X does not detect my sim card reads "error while trying to connect to network"
I am running CM 7.2 I have wiped everything and reflashed still no luck.
Add one more to the pile...
I also recently began having this problem, but my device previously worked fine.
I have tried Restoring to Factory V21Y with Mar 11 Baseband
Flasing a GB Based ROM & Stock Kernel
Flashing CM9
Flashing CM10
Entering *#*#INFO#*#* Phone Info and modifying frequency band (No Go).
At one point I was able to read the Phone # from the SIM card, but couldn't get a lock on Netowkr. I can visually detect T-Mobile and ATT in Mobile Networks.
I have tried this with 4G Enabled SIM Cards and older T-Mobile SIM Cards.
I have tried Simple Mobile, Straight Talk, & ATT SIM Cards.
I have tried using None APN's, the TMo/Simple Default APN's, and Modified APN's for Straight Talk & Family Talk.
No avail.
Any ideas?
I had the same problem. A new SIM card fixed it.

I gave my friend my old G2x because she was switching from AT&T to TMobile. She went to the TMobile store and got a new SIM card and her old AT&T number transferred to it. It works on her old iPhone but when I insert the SIM card on the LG G2x , it keeps saying 'no SIM card inserted'....do i need to flash a certain baseband on it and/or setup a custom APN for it? I am on the stock ROM thats rooted...
Any help is much appreciateed
Sorry for not replying until now but I rarely visit here anymore. My G2X had a bad Sim card which a new Sim fixed. I just had to wait until the network could authorize with it.
With AT&T you can simply throw a sim card in and away you go with any phone you want. What do you do on AT&T namely if you have an iPhone and TBolt?
You wont be able to do it without going through Verizon to have your TB Sim card reset everytime you want to use your TB after using your iPhone.
Normally you just have to do a simple ESN swap (can do online). Unfortunately with the Thunderbolt and it's LTE SIM, things might be more complicated. I'd check with a Verizon rep to see what would be involved.
Sadly its a complete pain in the butt. One of the guys I work with had to deactivate it and reactivate it a couple of days later. The guy in the store couldn't figure out how to do it, and it took him about 3 hours on the phone with various techs to finally get it working. They ended up having to swap out the SIM card in the store.
Not sure if its the process that is tough, or if they just don't know what they are doing. Either way, I wouldn't recommend it if you can avoid it. If you really need to do it, it is possible, but its not as simple as just swapping out a SIM card like on AT&T.
Once there are more phones utilizing LTE wouldn't you just be able to swap out your sim card and put it in any LTE phone?

Yes, this is correct. I can go buy the Droid Charge, and put in the SIM from my Thunderbolt, and I'll be good to go.
Thats pretty sweet, I wish I had the cash to drop on some more LTE phones when they come out.

Are you sure about that? I thought we were still using CDMA for calls and there is no voice over 4G/LTE on VZW just yet.

Pretty sure this is wrong.
When setting up my phone the rep had to set up the sim card and phone separately.
Razorz is right, we still utilize cdma for voice, so it may be possible to get data on a new phone but no voice?
A rep told me you could, never tried I don't have another Verizon phone to swap it out with. Also ATT charges activation when you swap sims "if the sim is in a different phone for a lengthy time". Also ATT will add a data plan to your account if the phone you put it in requires one.
the id number for the sim card and the ESN for the phone both must be in the verizon system associated with your phone number or the device will not work.

they didn't know what they were doing.
When I had data problems with my TB, I switched to my INC via the activate phone link on the "my account" web page. An hour later when I tried to return to the TB, I got a prompt for the phone's IMEI, then prompted for the SIM card's number.. It error-ed. After calling CS, the rep couldn't help, got TS on the line, they manually entered the SIM number to make it work...
So it appears switching away from the TB deactivated the SIM, to switch back, VZW's TS had to re-add or re-activate the SIM.
And as thetwiztidfreak said, they did need BOTH the IMEI and SIM numbers to re-activate the TB.

Correct but when you put the registered SIM in another LTE device it registers that handsets IMEI with your account. You can infact do a SIM swap with LTE, since your phone number is tied to the SIM putting the sim in another device effectively activates the phone on your account.
I should know, it's my job ;-)
It works the same way as GSM, but going from an LTE phone to a CDMA phone is a bit different, the SIM gets decactivated and becomes useless and if you want to switch back you need to go the a Verizon store for them to sell you out a new SIM for $0(some times old SIMs can be reactivated however there may b e issues with this). It's a PITA so I don't reccomend switching back and forth between CDMA and LTE devices unless you absolutely HAVE to.

I can confirm that it is a royal pain in the ass to go to the vzw store to get a new sim...
I just got a replacement for my tbolt. I had 5 days to return the "defective" one. I bounced the SIM card back and forth between the two phones a dozen times trying to see which one got better 3G/4G reception. The rep told me to decide which one works better and send the other phone back. It didn't matter.
Wondering if anyone can help, im using team Eos European 3g rom zoom. now i tried 1 sim card and the 3g works perfectly but when i try my other sim, i enter the pin code on screen , it accepts it, then immediately says "Sim card removed, the mobile network will be unavailable until you restart...." .
The sim card definitely isnt broken because it works in my phone and 3g modem on my pc. I've tried restarting the xoom with Wifi off and no luck.
Thanks

how old is that "other" sim card? Reason I'm asking is that sim cards use different voltages and old cards tend to cause problems in modern devices.
Around here, providers usually swap sims for free if you say that you've got a problem with one, so I'd go for an exchange if your sim is older that maybe two years...

Its actually brand new, got it on the weekend. It works perfectly everywhere else. I think i'll go to the provider anyway today and see if i can try a sim swap.
This really is baffling me now. I went back to the providers store and tried a different one of their sim cards and it doesnt work either. I just cant understand why my xoom can read certain providers sim cards and not others? (Its definitely not network locked). Could it possibly be the type of sim card (as in a 32k vs 64k etc)?
Any help would be greatly appreciated
I'm performing research into an odd issue that may affect custom ROMs across multiple devices, and I'm hoping a few people can help me.
If you're here, you probably know that Sprint is a CDMA carrier. The SIM card is for LTE only, and so removing it should not affect ability to make calls, and the phone should still get 3G data just fine.
On my stock Lollipop Note 3, it works as expected; a notification bugging me to insert a SIM, but otherwise works fine with 3G.
I had a Samsung rep take the SIM out of his Sprint Marshmallow S6, expecting it would work the same... but instead it completely killed the cell radio. No connection at all, no phone calls, no Mobile Networks option in Settings.
On ports of Note 5 firmware, the phone will connect to the network for phone calls, but absolutely not allow mobile data to turn on. However, this seems to be because the source ROM is GSM only - the Sprint kernel and modem allow it to use CDMA, but the UI still can not fathom having mobile data without a SIM and simply disables the option. The same happens with an S7 ROM port (also from GSM-only source). With a lot of command line %&$#ery, I managed to make it use 3G, but only for about 10 minutes before it catches on and the phone has to reboot.
Now the question I seek to answer is whether the ROM port issue occurs because the source ROM was GSM, or because Samsung just removed the capacity for CDMA-only data from more modern phones. Once I know that, I can work toward fixing it. As such, I humbly request that a few people boot their Sprint Note 5's on stock(-ish) firmware without a SIM card, and let me know if they can use 3G like that.
Cheers! :fingers-crossed:
Newer phones have different hardware. The S6 and Note 5 need the SIM card to authenticate with LTE and with CDMA/EVDO. A rom change will never fix this. This is the next way phone manufacturers and Sprint want new phones to be built. The CDMA and LTE are one authentication.
Your Note 3 had the old way of authentication, where the CDMA portion was separate from LTE. Hence, when the SIM card was removed, 3G worked because the CDMA authentication was embedded into the device.
New phones will not allow this, and honestly, the only reason you were able to use Sprint CDMA without the SIM card is because Sprint has your device ID and let it authenticate for a bit, but then the network itself rejected you because there was no authentication mechanism.
That's... all really a wonderful theory, but the whole point is that current research is indicating it doesn't work the way anyone thinks it does. Even the Samsung rep was shocked that his phone behaved the way it did.
As of right now, I have located one Marshmallow ROM that will allow 3G to work perfectly without a SIM, but have not heard back from the dev on how; it's based off CM, which in my experience will not. The ROMs that don't, don't stop because of authentication issues, they stop purely because of a UI trigger. Otherwise just rebooting wouldn't allow it to be fine for another 10 minutes.
Hence, research. I know all about what it ought to do. And why, and how. I could write a paper on it. I want to know what it does. For that, I ask only for some kind soul to boot their phone without a SIM for two minutes.
That's because its not a theory. It's reality.
In a cdmaOne/CDMA2000 ("CDMA") network, the UICC contains a CSIM application, in addition to 3GPP USIM and SIM applications. A card with all 3 features is called a removable user identity card, or R-UIM. Thus, the R-UIM card can be inserted into CDMA, GSM, or UMTS handsets, and will work in all three cases.

I fried my SIM card when I first got the phone by using QPST to try to flash a custom PRL. Not only did the phone power cycle every 5 minutes, but it lost its entire connection to the network. No 3G, no LTE, no 1x. When i went to replace the SIM card, the rep went through about 5 cards until he found one that was actually a UICC card, as the others were ordinary SIM cards just for LTE.
Also, please don't tout research on XDA. Your research is at best an observation with one ROM, and my guess it was a fluke where Sprint didn't reject your connection. Research requires actual proof and peer review. One ROM working one time doesn't warrant research. This isn't an issue with a "UI Trigger" as you put it, but its just the new way phones are authenticated.
Try removing a UICC card from a recent Nexus device (6,5X,6P), it will lose all connection as well. Why? Not because of a UI Trigger, but because new phones need the UICC to authenticate both CDMA and LTE.
Finally, unless that Samsung rep was a Samsung engineer, he is just a salesman with little tech knowledge past what is needed to sell the device.

Similar issue with HLTESPR (Sprint Note3) moved to Lineage OS 5.8.2 can not make calls with SIM card inserted. Remove the card and the 4 works fine (no LTE). APN and Carrier show up in settings.
Replace the SIM card no APN's no carrier, no phone unless on WiFi.
