The 4g AT&T networks are usually rebranded 3g. So yes, 3g should work fine.

Not true. SIM profiles will change and when you upgrade to a new data network the older SIM may not have the full profile and can't get it via SIM OTA.

you guys do realize that ATT is marketing their 4G, when its actually only HSPA+?
also, you seem to think that the SIM card is going to need to be changed for '4G' speeds? why? the only thing that needs to change for '4G' is the hardware has to support it.
SIMS cards do need to be changed from time to time because of types of services or network upgrades.
Older SIM cards may still work but that doesnt mean you will always get full network/sevice potential.
There is good reading outside of XDA about this if you search a little, and ignore the junk search results

What's this then:
http://www.bgr.com/2010/10/21/att-starts-switching-to-lte-compatible-sim-cards/
Cingular changed their UICC profile (SIM) in 2005 when they introduced ISIM and USIM profiles to support 3G. Now to support LTE, they've introduced... wait for it... a new SIM! OMG!!!!
BTW, LTE unlike HSPA+ uses a totally different core called EPC and thus has a different APN and several other new profile settings.
BTW, BTW, APN is typically a device driven setting and NOT a UICC setting. There's a difference.

Anyway, AT&T shipped me a new SIM when I received my Atrix 4G. Not really sure if it's necessary but AT&T did that.

Since you have practiced, you should be correct. I didn't get a chance to test my original SIM in Atrix.
However I still recall my China Mobile SIM didn't get 3G while roaming in US... Maybe just my problem.

Sounds like the sales rep you dealt with was a confused. New sim cards have been released for LTE, but they are not supposed to be activating them until the old sim cards are depleted.
AT&T has released a new batch of SIM cards that will support HSPA+ and future LTE devices. I have attached a image of what the new SIM looks like. You will not notice any difference between the new SIM's until you begin using LTE devices in 2012.

So I just got my Samsubg Infuse however when I switched the sim card from my Atrix to the Infuse the Infuse could not read my sim card...I get the "Sim Card Not Installed"message. So I went to 1 AT&T retail store and 1 AT&T device support store to have them switch out my sim card and after THREE new sim cards NOTHING (keep in mind these are all the "newer" sim cards AT&T gives out with no design on the front)...I keep getting the same message.
SO I tried an OLDER sim card I had sitting around (the "OLDER" version with the "3G" symbol on the front) and it indeed did read it. So what I did was call AT&T and had them switch my account to the "older version" sim card I had an VOILA everything works...so i thought stranger...such a new phone but it would not work with the newer sim cards AT&T store gives out....
So I talked to Samsung directly and told them that I think I had a defective device...they said NO because it reads my older sim card and I went on and on about how the only sim cards AT&T issue are the newer ones...they said they will open a ticket blah blah blah...Im hoping I can get a new device because if I ever had to sell this out or need a new sim card I'll be SCREWED....
But I was wondering what sim cards are you guys using...the newer AT&T one or the older "3G" one...plus does anybody know of anything I can try...
I tried resetting the APN, hard reset, soft reset, battery pull etc etc...but nothing...
Using the new one without the design on the front. No problems here sorry... I would say your device is faulty

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.

What do folks know about the MT4GS on the AT&T network? I used the Sensation exploit to sim unlock the phone. Got the code, entered it and it says network unlock successful but I can't get it to connect to the AT&T network once I insert the AT&T sim. I attempted to add the AT&T apn settings to the MT4GS but they won't save. I have a network unlocked MT4GS and an AT&T sim card.
Can anyone offer any advice?
Is your sim card activated? And have the proper data plan?
You need to go to the att store and have it activated and then have the towers updated.
Thats what my brother in law just told me who works at att. He said you can call them as well.
I actually have an att sim he gave me thats active, but needs to be paid, so i couldnt test it. I used it to unlock the phone.

Love you all are weighing in so quickly to help me think about this problem. XDA really is the best. I've tried all the things suggested and still no luck. I just had a thought that I'd like to run by you all. The phone is 4g. Do I need a 4g sim card from AT&T? The sim card is active. It's moving from an unlocked T-Mobile Vibrant to this unlocked T-Mobile MT4GS. So I know that the sim card works and can be used in an off-network device. But I don't know much about 3g/4g and sim cards. The current plan is 3g data on AT&T.
The problem is that the MT4GS behaves as if the sim isn't even there. I can put in a Simple Mobile sim and it fires right up. I can put the AT&T sim back into the Vibrant and it works right away. So how do plans work with sim cards?
If it is a 3g plan will the MT4GS not even see the sim card?
You guys rock.
It could be. make sure the sim is in right way and it isnt badly damaged. Since simple mobile works it leads me to think the sim is having an issue of some sort.
I would try getting a new sim from att with a 4g plan, see if that works. If im not mistaken, theyre free, if you get a paid plan.

After you enter the new AT&T APN settings make sure you hit the menu key to actually save the APN settings. Just hitting the back button well NOT save the settings at all. I'm using the MT4GS with my AT&T account and everything works great. Although you well NOT get 4g or even 3g, you well get 2g.

Just wanted to confirm it's working here too. AT&T sim (it's a 4G sim, from my SGS2) in a sim-unlocked myTouch 4G Slide running Bulletproof 1.something. APN had to be entered manually, but I didn't have to manually tell it to use AT&T.
The issue was Cyanogenmod. I don't know why or how but once I flashed Bulletproof 1.1 it took the AT&T sim fine. I reflashed CM in order to verify and it wouldn't take the sim again. I don't know. After flashing Bulletproof 1.1, I used the Tweakker app (an app I wish could be included in every rom) to get my AT&T APN settings and everything worked from there. Thanks everyone for the troubleshooting help. I don't know why it seems to have issues with our CM rom and the AT&T sim card.
The phone is, as we all know, limited to the edge network while on AT&T. Thanks peeps.
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.

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.
