[Q] Sim Card Error - Galaxy S 4 Q&A, Help & Troubleshooting

I have literally been searching this site for hours trying to find an answer but nobody goes into much depth about this problem. My i9500 cannot detect my sim card at all. I have replaced my Sim Card Tray twice since receiving the "sim card error please restart phone" notification because it didn't seem to fix the problem the first time i replaced the tray and I wanted to be sure it wasn't a bad tra. I have tested the Sim Card in 3 other phones and it definitely works so I don't understand what else it could be. Please help me guys. I need this phone for work and I can't afford to upgrade right now.

SIM card issue... any advice?

I'm not sure if this is a common issue or just an issue with my sim card.
Looks like the sim card just stopped working this morning. I can't make/receive any calls or texts and the lock screen says "Please insert SIM card and restart".
I've restarted about 3 times now and have tried removing and reinserting the sim card, with no luck.
I figure I'll need to take it into a T-Mobile shop to get a new sim card, but my Vibrant has been rooted and has a the Obsidian Froyo rom installed.
Should I just plug the SIM into my old blackberry and take it in that way for replacement?
Or is this some known issue that can be easily fixed?

I have had this happen to me twice. Once, the SIM went bad (it happens).
I called TMO told them that it's not working & they said they'd get me a new SIM. I had the option of going to an authorized TMO store or getting it mailed to me. I went to a store, they installed & it off I went.
The other time, I took some rubbing alcohol and a QTip to it & cleaned it up, let it dry, put it back in & it's been working for a little over a week now
So, I'd try giving it a cleaning first and if that doesn't work, give TMO a call.
If they don't know that you have the Vibrant and think you still have a BB, then yeah, I'd put it back in that rather than bringing in the Vibrant if you have to go to the store. It's just easier when the person helping you isn't trying to force you to change your plan at the same time.
Question: The phone won't let you do anything without a SIM card? If that's true, that's just another reason to be glad I SIM unlocked my phone....that would get annoying!
Old Tmobile sim cards actually have a certain amount of times they can connect to the network tower. If you use airplane mode a lot it you may reach this point quickly.
And some sims cards just go bad. Which I think is the case with yours tjhart85. Take the phone and card to Tmobile. Tmobile will change the sim card for free.
Yup, turned out the sim card just went bad. Called up T-Mobile customer service, they put a not on my acount, and went into my local T-Mobile store and got a new sim card. Phones working great now. They didn't even ask for the old one and didn't have to look at my phone.
Thanks guys!

[Q] SIM Card issues with CM7 on HTC Inspire 4G

So for a while now (probably 3-4 months) I've been having SIM card issues and I don't remember if they started before or after my phone was rooted and running CM...Anyway, a little SIM card thing shows up in my status bar and it says like "SIM card not recognized" or "Please insert a SIM Card" or something along those lines. It doesn't let me use the network at all. Usually I fix it by turning the phone off, taking the SIM Card out, putting it back in, and turning the phone back on. Sometimes it'll work, other times, I'll have to repeat it. I thought the problem was the SIM Card because it had 3 scratches on it from the contact points, so I got a new SIM Card yesterday but it's still doing the same thing. When it started I was either on the stock ROM (unrooted), CoreDroid, or CM7 (stable). About a month ago I started using the CM7 nightlies.
Does anyone know what the problem might be? Could it be the phone itself?

Same exact problem here. I don't run nightlys but I really need to try something that I'm not ripping my phone out of the OtterBox in the middle of school.

NO SIM Card Inserted

Hey,
I keep getting this annoying message " NO SIM Card Inserted " and my trick is to turn the Airplane mode on/off for a couple of times so the SIM card is recognized again. But this is getting worse, I'm having this error the 4th time today and having to switch the airplane mode on/off for countless times before it works.
Anyone else having this problem?
Should I get my tab to service?
Samsung Galaxy Tab 2 7.0 P3100, Android 4.0.3 stock
Noboby having this issue?
I have it too. I think it's just the default message if there is no sim card inserted. When you put one in, it goes away. I don't really mind it. What I DO mind is a "--" symbol in the bottom notification bar. I used to be able to see the Weatherbug Temp or the Battery status percentage there, now I can't. Can't figure out how to get rid of it. (--)
Maybe I wasn't that clear, but I have an Orange sim in it.
Yesterday this problem with the sim was worst than ever so I'm going to Orange for a fix. Hoping that another sim will just do the trick.
i got a broken sim once after some rooting and flashing custom rom's
in my case it was clear the sim (because everithing worked well with an other sim)
and my sim was relay old (around 7 years). So try with another from a friend and you know. :good:
So it seems that I had a faulty sim and everything is ok since I got a new one. Problem solved.

[Q] S4 unlocked: reads original SIM but suddenly No Sim Card Error on new SIM

Hi all, I have strange problem with my S4 GT I9505. I read various forums and searched but couldn't find a similar case to this strange problem. I am quite new to android and hope that maybe somebody of you would be able to help me or point me in the right direction to solve the issue below.
Issue
I had the phone unlocked from my provider O2 in UK and moved outside of Europe. My S4 accepted the new SIM card for the first 2 to 3 month. At this time my S4 was unrooted. Out of the blue it started with no sim card error, please reboot when using the new Sim Card.
Here is a list of all changes I done but it didn't help
- unrooted: Factory reset Kitkat, updated to Lollipop
- Rooted the phone as above didn't help, installed various custom ROMS, stock Lollipop, Google play edition. After I flashed the ROM I have for a short time network with the new SIM card but then it starts again with the No Sim Card Error. However, I have no problem with my original O2 SIM card.
- Changed SIM card, checked my new SIM card with other phones and it worked, so it not a fault on the SIM card
- Checked with my provider O2 in UK: phone is unlocked,
- Tried to open Service Menu but none of the codes worked, went to EFS folder/carrier/hidden menu and changed OFF to ON, still could open Service Menu to check if the phone was still blocked etc.
Any guidance how to solve this would be greatly appreciated.
Thanks, Frank
Hardware failure. Replace the sim slot. No messing with software is going to fix that.

Thanks, I will try this next, hopefully this will fit it!
No reason it shouldn't, and it's arguably the easiest hardware fix you can do since the SIM tray isn't soldered to the mainboard. Just keep in mind the following: when you purchase a replacement tray, don't throw out the old one until you peel the foam pad off the top of the connector and attach it to the new tray. That pad prevents the connector from popping off the socket it sits in.

I changed the SIM/SD card holder today, however, I am afraid it didn't take long for the no sim card error to return. Only difference today, it connects to the mobile network again after reboot.
The strange thing is, I don't get the SIM card error when inserting the original 02 Sim card, only when inserting a none 02 card (phone is unlocked)
Would this mean that the motherboard is defect?
Most likely, yes.

I have an issue with my fiancée s8 plus

My fiancée s8 plus her SIM card got stuck in side the window card hole she used a pin to get it out in the process she tells me her SIM card tray got bent and the SIM card won’t read at all.
She took it to sprint they said it’s broken the unit and they did zero trouble shooting.
Before I order her a new SIM card tray to see if it works what can be done ?
Is the SIM card tray the problem ?

I've had all kinds of issues with the Sim tray on this device. I've replace mine several times. If it's needed up there's a chance. But no one can say yes or no without physically trying what your doing.
