Does anyone have any experience with those "proxy" SIM cards that sit in between the actual SIM card and the phone? Since it doesn't seem like any of us are going to be getting our AT&T sanctioned unlocks for another 10 months, these cards seemed to me like a possible alternative.
If anyone has one, I'd be interested in hearing if you can get it to work with your Captivate.
I have an iPhone 4G...I am about to buy a AT&T Galaxy S...is it possible to have AT&T make an extra SIM card so I don't gotta switch the sim card between each phone all the time? I could just keep one turned off when I wasn't using it? Not sure how or if that would even work...I would just like to be able to switch between the two phones easily...
any ideas or thoughts?
Thanks...
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.
I have a T-Mobile sensation,S-off, xboarders CM7 rom... located in AZ. I do not have another sim card for another carrier, I obtained the unlock code from the terminal emulator method. I "THOUGHT" unlocking the sim card was enabling my current sim card/sensation for t-mobile, to work on other carriers.
However I obviously learned that the only way to enter the code was to insert a sim card from a different carrier, and enter the code. That being said, if I insert another sim card in my phone "like a friend with AT&T", will it affect his sim card at all? And when I put my sim card back in, will I be able to use different networks? Will it lock my sim card out of my phone or vise versa? I have been researching for a while now and I havent found too much defining what im looking for. Any one who can enlighten me would be appreciated!
all unlocking your phone does, is allows it to use different sim cards to run on different networks.
your available networks are controlled by your sim card, and any unlocking won't change that. No it won't effect your friend's att sim card, and not it won't hcange anything currently. However, if you were to get a different carrier that uses sim cards, then you could freely insert that sim card and then use their network with their sim card, provided you have the available frequencies supported (i.e. 3g/4g).
That makes sense. So people who have their phones sim unlocked usually sell the phone or have another sim card for a different network, which means they pay for two data plans? Well I feel like I wasted my time, I sure am glad I didnt pay to get my unlock code. On the bright side, the research I did find mentioned a higher resale value for the phone. However I dont see myself selling my sensation ANYTIME soon !
I appreciate the input, and thank you for your time sir!

Its a wasted of time when you are on a contract and do not planned to sell the phone, but if you travel inside or outside the country is a DAMN good advantage cus you just change or get a local SIM and you dont need to buy a new phone.. you see?
And also like you said "higher resale value for the phone"
New guy here.
I recently purchased an AT&T i727 with the plan to use the bring your own phone program with straight talk. Even with the sim card activated, the phone reads "No Sim Card. Emergency Calls Only". I've used the sim card in other phones, so I know it's functional. I've rooted the phone and installed different roms, but I still get the same error. I can't edit any of the APN or network settings because it tells me I need to have a sim card inserted to do so.
I feel like I'm not super clueless at things like this, but I've done everything I know how to do. Any help is greatly appreciated.
Take it easy on me guys.
Thanks in advance
Sound like the phone isn't unlocked. There is a thread here on how to unlock it for free. Look in the general section.

Assuming the ST SIM is at&t SIM card , and it was working before , the problem might be somewhere around your phone , either SIM card slot , bad radio or blocked-from-network Skyrocket ... is it a craigslist phone ?
It is an AT&T compatible ST sim. I've already entered codes to unlock it and they all said the unlock was successful.
I actually purchased the phone on eBay. (I'm sure everyone will laugh upon reading that)
If the sim card works in other phones and doesn't work in your skyrocket but you have it in the correct way in the sim slot then it's gonna be your sim card slot. With ST your phone doesn't have to be unlocked for the sim card to work in it. Trust me on that I'm using my skyrocket on ST and have used about 10 different AT&T phones on ST and none of them were unlocked until I sold them. You'll need to get ahold of eBay and paypal (who you hopefully used) and try and get your money back. Otherwise you have a really expensive mp3 player.
Sorry for the bad luck but that's what it looks most like to me. I used to work for AT&T and that's the logical problem. I would say try and get a warranty for it but I doubt it still has a warranty and even if it did AT&T and Samsung wouldn't do anything about it because a problem with the sim card slot is considered physical damage. You'll just have to try and get your money back for the phone.
Just my advice and $.02
