Hello, I bought an unlocked version of the sensation originally from bell to use on AT&T. I had an iPhone 4 which had a mini sim and went to AT&T to switch it out, they gave me a normal sim but the data didn't work. I went there today to ask them about it and they tried to manually put in the APN settings, but had no luck. Does anyone know what the problem may be? Thanks in advance.
Do you guys think this is AT&T's problem? Could it be a problem with the sim change because I got text on the new phone saying"thank you for upgrading your phone" could it have taken away the data?
Just call them and check. You should be able to add the unlimited non smartphone data for $15 and still get the same 3g speeds. Tell them you switched to a dumb phone and give the sensation imei if they ask. Their system won't be able to recognize that you are using a smartphone.
If you need apn settings let me know, the default wap.cingular should work fine.

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.

When i had plenty of tmobile androids on att i never had to tell them, and i dont understand why they would update towers. Make sure you hit menu and select save in apn settings

I have an idea. Go to settings, wireless and network, mobile network settings, then network operators, click search and select att.

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.

You will not get 4g on the slide, so you don't need a 4g card. Differing spectrums. Vibrant gets 3g on ATT but its the only one.

Doesnt att and t mobile use hspa+ or ++? I was under the impression tmobile leases the same nodes att uses

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.
Go to the Verizon store and get a free SIM card? Why go through all of this trouble.

Thanks for the suggestion. Issue is that the phone is having the NO SIM error randomly. Have already tried a different SIM from Verizon (friend's account) but still have that same issue.

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.
thanks again bro

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...

That would be fantastic if you come across something that will allow voice/text/EvDO(3G)! Have you made any headway on this? Would be glad to help in any way I can also to get this working.

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.

A little off subject but I how did you get it on sprint I'm trying to get mine on verizon prepaid and have it set to nv only. I must be missing somethin because my esn/meid all look right I get data but yet no calls
Been searching for hours on how to get this working, but I've ended up feeling helpless and stupid which rarely happens.
I've got a friend's Inspire 4G here in front of me. I unlocked it using AAHT (which worked perfectly I might add), and dropped her Simple Mobile SIM card in, thinking it would Just Work (based on other posts I've read). Nope. No service. Period. Tried mucking with *#*#4636#*#* settings but to no avail.
She doesn't care about data (has WiFi at home and at work) but just wants to make calls and send texts. I know there's probably some stupidly simple solution to this.
APN settings my friend. Dink with those.

I bought a house and moved.
No service in the house with Verizon.
So, I switched to AT&T.
AT&T told me I would get HSPA+ with my Verizon S3.
Well... I have 2G, voice, and text.
Anyone have an idea of how to get HSPA+ enabled? Is it possible?
I have a custom ROM, but I can flash anything if it would help.
I don't think it's possible, they run on completely different networks (CDMA Vs GSM) and the phones radios are built accordingly.

There is a way cant remember where i read it, maybe on the t-mobile forum. I recently bricked my att device and came across a verizon variant and was able to use it for att with out having it sim unlocked just a few hours ago steps taken were as follows:
After swapping the motherboards i factory reset the non rooted verizon device from the settings menu as I was just going to sell it on ebay. I had been using wifi only on a sim locked t-mobile device but the camera was not working so i switched back to the verizon and was prompted to complete the set up after i booted the device with no sim card inside. I got the no sim card message and ran the app Region Lock Away that has a red circle icon and a black unlocked pad lock by chainfire. I was skeptical 1 for the device not being rooted but tried anyway. The app said it was not able to verfiy root and closed; however once I inserted my att sim card without powering off the device i saw signal bars. Now Im not sure the app actually did anything and I might have tried the app before resetting it without success but after checking the network mode in the mobile networks tab it now shows Global as the preferred network. So i started texting people and then calling all with success. Now im still on the edge network and this may not solve your issue but I remember seeing the work around I think it has to do with correcting the APN settings but there is always a way to get things done. Keep looking you will find it. Im just happy to have cell service again but Ill be looking for the thread in a day or so as well.
Forced into an AT&T phone. It worked for 4 days then stopped. Their tech support claims the tap wasn't compatible and they don't know why it worked
I had 2g for those 4 days
I'm always on wifi but noticed my data wasn't working so not an ideal switch but if you are in a bind it does work. I'm still running at&t network on this Verizon motherboard just fine
