Ya most likely the problem would be to unlock it. Not rooting or anything like that. Just unlock the phone and you should be on your way.

Hi all,
I have my primary phone which is an international SGSII and I have my Infuse as my secondary phone.
I experienced random reboots on my SGSII which I couldnt seem to explain and I started using my Infuse for a while now and it has now started to randomly reboot which it only has started doing since I put my sim card in it and had NEVER done it with no sim card in it so... Can these issues be being caused by a bad sim card?
The card itself is a bit old...
Please advise...
Anything's possible i guess, if you didn't change anything else or install any software on both that might have caused i would assume it would be the sim card.
Try one or the other for a day without the sim card and the other with sim card and see what happens. Then switch and re-test.
Interested in knowing if it's the sim card or not, as a last resort you could just buy a new sim card from an AT&T store.

Thanks for the response... I have switched out the cards again to see what is going to happen.
And just so you know... I'm in Canada on the Rogers network... not with AT&T...

Very possible since Samsung has implemented (since the Galaxy Tab 7" i think) a little "feature" where it forces your phone to reboot when it cant see the SIM. Its possible that the SIM is loosing contact and forcing a reboot. Hard to be sure though.
How many people have had to get a new SIM card to get their phone working properly?
How many different reasons have a new SIM card been needed for?
I've heard of a lot of people needing a new SIM card to receive the OTA.
I had to get a new SIM card as my phone would no longer switch to 4G.
Is there a hardware or software issue with this phone causing SIM cards to malfunction?
Is there anyone who's needed a SIM card replaced that has Not flashed or rooted their phone in anyway?
thanks,
I needed one to be able to check for updates.

Do you root and flash roms or other things on your phone?
I'd like to narrow down if this only happens on phones where that is done.
and then to nail down what we are flashing that is wrecking these sim cards if that is the common factor.
I had to get one once I went back to stock to receive ota. I do run a custom rom normally.

Mine is fine, but the other three in my household after receiving g7 can no longer check for updates. I wonder if Samsungs "no sim fix" somehow killed them. All three are unrooted, and never have been.
I have not yet replaced their sims.
Odin'd back to stock to receive updates, had to get a new sim in order for it to work. I run custom as well. I think it has something to do with how the sims are identified on the LTE network since Sprint and At&t don't have this issue.

Never rooted or ran a custom rom...100% stock. Someone mentioned that the update may have fried the sim cards....that's my thought as well.

Problem with that theory though is lots of people had to get a new sim card just to be able to take the ota.
Good to know this isn't necessarily cause from flashing roms and what not.
I also had the problem checking for OTA updates. I received the update just fine and then had the problem. I went to the Verizon store and the switched the SIM card out and problem was resolved.

Both my brother and I had to get new sim cards for 4g due to the phone warping our cards.
I had to get a new sim card when I upgraded from the galaxy nexus to the gs3. I believe it was because I had done a manual prl update when it was in the nexus. it seemed to work just fine in that phone but once I put it in the gs3 I couldn't get 4g unless I switched to 4g only.
I was on the latest OTA and I hadn't checked for an OTA since Oct. 3rd and tried yesterday and got a error. Went to Verizon and he said he didn't know if any issue with SIM cards being fried with GS3. I'm all stock and he argued that a new SIM wouldn't fix. I got him to do it anyways and now checking for updates works again. He still doesn't think it was a SIM card. But i beg to differ.

Had to pay 10 dollars and 40 minutes of my time at the corporate store for them to tell me they couldn't give me one, had to buy one, but it fixed my OTA issue. I'm gonna rub it in the "it appears you have done this thing called rooting your phone" guy's face. No s***. I flash a new rom every hour...

thats good.
Those punks should have giving it to you for free. They have to know by now that the sgs3 is eating sim cards.
Alright, so as usual i try and solve all my issues myself and avoid posting on forums unless im at a total loss.
Heres whats going on, I have a Samsung Galaxy S ii Skyrocket (Rodgers) i got from a friend. Im with Virgin mobile and the phone is with rodgers. The phone is unlocked and worked perfectly with Pacrom for 2-3 weeks. now it is not reading ANY sim cards ... Heres what ive tried
-Returning to stock rom (using odin)
-Had someone look at sim contactors (fine)
-Called both Virgin Mobile (said to call rodgers)
-Called rodgers (transfered me to virgin mobile)
-Restarting phone (removing and inserting sim)
-Factory reset (pacrom)
Nothing has worked and no one working at rodgers or virgin mobile will help or don't know anything. soo im asking you guys, any idea on how to fix this? Or atleast whats wrong with it?
Is imei also reading 0 or null? If so you might need to fix the efs partition.. Otherwise I'd say the sim reader is dead.

Fortunately, it's really easy to replace. no soldering required. A replacement is listed on Amazon for just over $13.
Hey everyone thanks for your help in advance... I just bought my phone and went to T-Mobile to get a new micro Sims card. After putting it in, the phone didn't recognize it. I put in the APN settings and it doesn't save it. This really sucks right now because I don't know what else to do. Any help will be greatly appreciated. And my phone isnt rooted yet, just want the stock for now. Thanks again
Is the sim activated? Sometimes on a new sim it takes a few hours to start working.
I was already on Tmo with an N5. I just moved the sim over and all was good.

What he said. If OP has another phone that uses a MicroSIM, put the sim in that phone and see if it works.
Also did u insert the sim properly into its slot?

I actually didn't. I agreeing with what you said and added onto your point.
I didn't mean the u to be directed to NaterTots but to the OP. Sorry for the confusion.
I screwed up and instead of using my old Sim card and cutting I went into T-Mobile and had them activate a new micro Sim card and put it straight in. The old one is deactivated.
The new micro Sim does work in my old gslaxy S2 phone which used an older big Sim card. Its now using a Sim adapter.

Did you insert the SIM card in the right direction and not upside down? I know thats silly to ask.
to be honest its simple man and actually nothing you needed to make a thread about. Simple go to TMobile store and try an already active sim card. Go to AT&T and see if they can put an active sim card to help you out. Basically go to anywhere that works with a TMobile or AT&T derivative and try it out. Nothing really else we can do to help you on this.
Not try to be rude or anything but its the truth. If none of that works then you may have to RMA. Also maybe find a friend or family member and try their sim . Good luck :good:
Should work. Using my one plus with Solavei (t-mobile based company) and having no issues.

First time i've also put the tray wrong. True story
Just had this problem after coming from using the phone overseas and no signal whatsoever on the phone despite numerous restarts, SIM cleaning, and chats with T mobile. After verifying the APN was correct I went to Settings-->About Phone-->Status-->SIM Status and checked to see if the SIM was connected(it showed my phone number, but was disconnected). So from here went to Settings-->Mobile Networks-->Network Operators and let the phone find carriers automatically. Mine showed T-mobile(with a little SIM icon to the right of it), Verizon, and ATT. I clicked on T-Mobile and it registered and is now working.
Probably saved me $15 at the T-Mobile store. Hope this helps even just one of you.
can some one please help me....i purchased an unlocked former sprint lg g flex 2 from ebay to use with my gsm sim card.
I have used the phone for 10 days without any problem but from nowwhere today it just showed invalid card.
when i reinsert the sim,it detects the sim for about 10 min and then brings a pop up on the screen saying "the phone ll reboot until you insert a valid sim card"then it reboots and stays on invalid sim.
Tried a different sim it also works for roughly 5 min and then does the same thing.
I have tried hard reset,factory reset,rebooting it and everything that i found on google but nothing works,still stack on "INVALID CARD"
Any help please i ll appreciate!

Best thing to do is return it. Never buy a sprint device for use on GSM carriers. Only buy a sprint device if you intend on using it on Sprint.

No clue. Getting it to work can be difficult or could be easy. But it's just not a reliable device to use on GSM carriers.
Did you make sure network mode is set to GSM/WCDMA/LTE?
If so your best bet is to check out this thread not sure if it still applies https://forum.xda-developers.com/g-flex2/general/sprint-g-flex-2ls996-gsm-domestic-t3122813

hi,
i have just discovered that my phone was already rooted by the seller after i ran root checker.
do you think if i unroot it and root it again would solve the problem that am having.

Just unrooting wouldn't solve the issue. The device was most likely rooted with changes to make it work with a gsm carrier. That phone in its stock state won't work on any other carrier at all besides sprint.

You should be able to since it's updating. But updating will actually make it to where you won't ever be able to use it.
You have more of a chance getting it working with a GSM carrier while rooted than not.
The issue your facing is not a problem, it's supposed to say that when inserting a non Sprint sim in the sprint device.
Remember that model has to be tampered with to make it work on a GSM carrier. It's not supposed to work on a non sprint carrier without things being changed.

Broken Antenna
I've had my LG G Flex 2 for a little over a year and this happened to me.
SOLUTION: The antenna is most likely broken and needs to be replaced. The lady at sprint said it is common with this phone so I'll try to figure out how to do that.

Yeah but your using the device on sprint? These users are not. They're using it on a GSM network outside of the US this issue is over the software not hardware.
