Lately out of the blue when I pull my phone out my pocket I see a pop up saying sim card not detected then I have 2 options. Shutdown or reboot. Is this the phone quality built a little out of place or what? I'm sure someone here has seen this message if not all of ya have.

Personally I would go to ATT and see if you can get a new sim...because apparently something is not right with the sim card.
or or or
It could be the ROM you are running, If you are running a Rom...
Running android revolution 5.1.6. Crazy how could it be the rom?

Possibly just a bad installation...
Although it is a reliable ROM they all have glitches, possibly it is the ROM and you should try re flashing it and if the problem is fixed you know it was the ROM, and if it doesnt work Like i said before, your going to have to take a trip to ATT.
It could also be some type of hardware failure in your phone, not sure though.
Have you tried using the SIM in a different phone?
Faulty SIMs aren't unheard of.
Nope just this one. It only pops up every now and then but today it did it twice back to back so now I was like wtf. And decided to ask if anybody else seen this before.

My sister once had a bad 3G SIM card that would only work on EDGE. We were right by an EDGE/3G border, so we could take 3 steps forward and have a working phone in the EDGE zone, or 3 steps back into 3G and have nothing.
My Tilt phone worked fine in both "zones," so I put in her SIM and had no signal in the 3G area, heh.
Oh.. well if the problem is persistant ill just get then to make me another similar

Uh oh...
Same problem for me here as well. Running CM7, was working fine until later in the evening when suddenly the network "died", and after several reboots noticed the little SIM problem icon next to the signal meter. I had the card locked, but went into settings and unlocked it. Now, logically if the phone couldn't read the card then technically I shouldn't have been able to change the PIN, so...
Confused over here. Is there a known fix to this? Or worse - how do I broach the subject with ATT if I have to go in?

I don't know about the fix about it, but concerning talking with AT&T, I'd recommend calling Warranty exchange first. They'll let you go through some hoops like getting your imei and possibly cleaning out your sim card with a rubber eraser. They'll also run some network tests on your phone to see if there are any "down towers" in your area. In the end, just request for a replacement sim card from them and have them note on your account that you want to get it free. Ask for confirmation if it's in your account, then head for the nearest AT&T corporate store. They'll tell you you'll have to pay $25 to get a replacement sim card or something, but just say that warranty sent you and it's noted on the account: should get you your sim for free, if possible.
I have never had a problem getting a new sim card for free from a corporate store. Just go in and ask for one.
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.
Thank you and have a good day!

I don't think it was a very good idea to dial the *228, further more you may need a new sim card now.

Never *228 a 4G phone. A new sim is in your future, assuming that you have cdma/lte enabled under your network settings.
You guys were both right, SIM was done. I had to restore back to stock just to take it in, now re-rooting.
I took the SIM card out of my vzw GNex and put it in my vzw gs3. Everything works but I can't get 4G. I tried playing with the data settings but no luck... 3G only. Any suggestions?
Open settings, more, (something about access point names), and you should see one that says LTE in it. This is all off the top of my head, but I think I remember having to change that on mine as well. However, I'm now on AOKP and can't help too much.

Those are the APNs, tried changing that with no success.
Actually, same. I just switched my sim from a nexus to a S3, and I only get 3G, any advice would be awesome!
Made sure she was in LTE/CDMA.
I am having the same issues, if anybody has any solutions they would be greatly appreciated.
I assume you guys tried flipping airplane mode on/off real quick right?

Yep, tried that. Also changed settings and rebooted with no change.
I did the same with my gnex and had the same results. After some time in the phone with Verizon tech support, the end result was go to the Verizon store and get a new SIM. I did and 4G appeared instantly. I told the Verizon store rep I had read you could just swap the card. She replied "nope, different type phone".
Bottom line: no 4G...go get a new SIM card. (As a side note, backup assistant showed up on my bill at no charge...it hadn't with the Gnex SIM)
This is great to know. Just switched from a Nexus to an SGS3 and no 4G either... Honestly I figured the eBay phone I had purchased was suspect, good to know it just needs a new SIM....

Same scenario...bought from eBay and thought I would have to do a return.
Anybody knowledgeable know why this might happen?
My sim has worked on: Motorola Droid Bionic and D4, LG Revolution, Pantech Breakout, HTC Thunderbolt, and Samsung Galaxy Nexus.
Seems weird that it would work on all of those phones but not this one. Still going to try a new SIM, but I can't wrap my head around why I would need to. Especially since VZW has to allow device swapping via sim (as per the FCC). Once I do that I will definitely report back. Keeping the phone either way, can't beat an SGS3 for $200 bucks...
Regardless of everything I said in my last post, replacing the SIM worked. Would love to know why, but the tech wasn't interested in answering my questions. He seemed more annoyed that I was an evil rooted user, tried to blame the initial issue on that...

Hello everyone! I have recently moved from NY to CA. Back in NY I had data speeds of 25+ mbps. Since I have been in CA my speeds have been much lower, sub 5. So I updated my towers with *228 and now my data speeds are EVEN WORSE. I only get 3G now and my speed is 1 mpbs at best. I'm currently running the latest version of slimkat, and I haven't updated my radio in as long as I can remember. Could the radio be my problem? Anyone have any ideas or maybe something to troubleshoot? My data speed makes it so some apps/games are barely usable. Thanks for your time.

You probably fried your sim card, you aren't supposed to use *228 on lte devices. Go over to Verizon and ask them for a new one.
As far as data speeds go, there isn't much you can do. You can switch to a touchwiz rom, and it should give you better reception, but it won't give you data speeds that quick.

I just had to say this. BadUsername, while you are correct that dialing *228 does in fact break 4G functionality, it does NOT fry your SIM card. What it does do however is put you on a 3G only PRL. Now when you go get a new SIM card it goes through the activation giving you a new 4G capable PRL #. I have read people say that they are able to get back on a 4G PRL by driving to another city (or another tower) and powering off the phone and removing the SIM will put you on a new 4G PRL. I haven't tested this however myself as I have never been stuck on a 3G only PRL.

Went to another city and had to reboot a bunch of times but I got LTE back. When I came back to my home city (where I had done the *228) and then rebooted my phone it went back to 3G. So it appears that my SIM card is now stuck in 3G at my home tower(s) but can get 4G else where... need a new SIM I guess. Regardless, my data speeds around where I live suck and it's really annoying. 10 mins south from where I live I am getting 10 fold increase in data speed. Thanks for the input guys!

Take the SIM out, boot the phone back up with no SIM card, let it sit for 10 minutes, power off, reinsert SIM, reboot phone. Should fix it.

Just wanted to update in case this happens to someone else. I did what you mentioned for 10 minutes, and then again for over 30 minutes and it didn't fix the problem. I went in and got a new SIM card and now I am back to LTE. Thanks for the help guys!
I've been having a network issue lately, thought it was the software update. I got a new simcard when I got the phone but the 10 minute trick has worked for me before, I usually have to do it a couple times though.
