sim card removed?

I'm in India right now on vacation. I own a rogers s2 lte. Recently I've been getting random popup messages saying my Sim card has been removed and i need to restart the phone. Thing is I did remove the Sim card for a minute or so a few days ago but I'm still on the same rogers Sim card and the phone is in flight mode the entire time. Its annoying for this to happen. Any ideas?

It could be a ROM or radio issue. Could also be a sim card slot issue, bent or broken pins etc.

Wish I could help, but you need to give more info. Are you running stock or a rom? Have you dropped it recently? It could be software or hardware, but nobody can help you if you don't give any info.

[Q] Not Recognising Sim Card, Any FIx?

Hi All
I have a Galaxy Tab 2 7" Model GT-P3100 I have not used it very much as I mostly use my S3. I bought it from Hong Kong, when it was tested in the shop in HK there was no issue with anything, all worked fine. I have since brought it back to England, mostly used it on wi-fi at home, then recently I decided to get a sim card to put in it to use it out and about.
When I put the sim card in, it comes up with a message box "SIM card added - Restart your device to access the mobile network - Restart" so I click restart and wait for the reload. But it doesn't recognise the sim card and still has "No SIM - Insert SIM card" within the notifications box as ongoing.
Now if I remove the sim card from the device while it is still on, it comes with a message box "SIM card removed - The mobile network will be unavailable until you restart with a valid SIM card inserted - Restart"
This sim card I am using has been tested in other phones and it works no problem, it is a pay monthly contract with Orange. I have also tried other SIM cards in this device and have the same response from every one.
So after doing some reading online and on this forum, I rooted the Tab and then used GalaxSim Unlock to unlock the phone, thinking it may be becasue I bought it in Hong Kong, the Tab is now unlocked but still shows the symptoms above.
Is there anything else I can do to get it to recognise the SIM or do I need to unroot it and send it back to Samsung?
Any help is gratefully received.

flash a custom rom ( stable is cm10.1.2) or a customised stock rom.I thinks it will fix your prob

It is not a ROM related problem.
Go to your network operator and have your old sim card replaced with the new one (with the same number if you want). Sometimes, an old sim card just don't work with newer service. G' luck..

Thanks to you both, the sim card is new, only 2 months old. I have just flashed CM10.1.2 and not only does it not recognise the sim card, I also can't do anything as the android keyboard crashes all the time.
I am going to try to reboot with the latest nightly to see if that helps.

I am now running the latest CM 10.2 from 21.8
The SIM is still not recognised and now my PC is not recognising the Tab either.
When I first plugged it in it came up with installing drivers for Google Galaxy Nexus?? Is this normal

Hi this is the same problem I have on mine,I am starting to think it is the card reader that is the problem ? which wont be a easy job to replace for me

Might be hardware problem
use triangle away to wipe binary on downloadmode then install a stock rom and contact service center to repair it under warranty (if your device have warranty)

Just flash a different modem

[Q] Need help with my network name!!!! please help

I recently damaged my old sim card and got my replacement two days back.
after i started using this sim card, in the scrolldown menu / lock screen, where the network name is displayed, i get: '[email protected]@@@@@@@@@'
now EE is my network. but these @s came out of nowhere. they arent there without this sim card
i have already ordered another replacement but meanwhile any quick fixes? maybe a way of changing the exact text thats displayed there?
specs
gt-i9300 non-lte
EE network (which functions normally by the way)
android 4.3 stock (can bee rooted if fix requires so.)
also this sim card has the so called quicktap / contactless payment feature and the previous one didnt
anything at all?
i rebooted, reflashed the firmware and also tried cyanogen. no use.

Ask in the i9300 forum.

No SIM

I have been getting a no SIM error on my Verizon Note 5. Probably happened 5 times in the past 2 weeks. Reboot temporarily fixes the problem.
Anyone else having a similar problem? I will probably try to get a new sim from Verizon.

No issue here. Have you re-inserted the SIM card? If that doesn't help take it to Verizon.

Yeah, that was the first thing I did. It happened 3 times yesterday. I will call and get a new sim.

Same problem here. Was really bad last week and now hasn't happened for a couple of days.

I ended up getting a new sim card yesterday from Verizon

Happens to me at least 2-3 a week. Also drops from 4G to 3g, and sometimes my service doesn't even work. A coworker who has a Note 4 on Verizon mentions he has to restart his phone every few days as well because his connection just goes out sometime. I don't know if it's a software issue or if Verizon is just being ****ty right now

I finally got the sim replaced today. Hopefully this will fix it. Really don't want to reset the phone or exchange it.

I have had a new sim for a day now. The error has not popped up again yet. I will check in again in a couple days.

Just got the error again today. Thought I was good.

I was having the issue quite regular and, took my sim out and cleaned it (wiped) off what looked like dirt and have not had the issue yet.

Have you resolved your issue yet? I just got the error again. It's been weeks since I've had it

I had the error once or twice since I swapped Sims. I have not had it happen again since that last post.
The only thing I did is clean the sim card and blow out the sim port.

I ended up going to get a new Sim and no more issues with it. I do see any times I lose data connection and then it reconnects.

I was at Verizon was out when my phone froze...waited 1.5hrs, when all needed to be done was hold the power button and the down volume button simultaneously to create a battery disconnect to reboot....I asked about this same issue as I was doing a system reboot when the Note 5 froze....she said the phone when not receiving service will automatically switch to "global" to maintain connection but can't switch back...need to go to settings->mobile networks->check the network mode to verify it's in the lte/cdma mode, if not select that.....IDK, it happened at my house where I have a network extender, so that shouldn't have happened.....saw this solution somewhere else....saying the slot may be a little loose causing the connection to be unreliable, I'd start w/ something thinner than copy paper first....or wait for the "masters" to comment....:
If there is a little room for SIM movement in the slot then the contacts between the phone and the SIM will not meet causing this issue. Try to cut a piece of paper the size of the SIM card and place it on top of the SIM ( not on the side where the gold connector is). Insert both in the SIM slot then check if the problem still occurs.

This happen with my galaxy 4, and i changed the sim card, but the problem still happened, now my new galaxy note 5 start the same way. Sucks

Me too
I have been having the same issue twice a day now for at least a week. Guess I need to make a trip to the Verizon Store.

I had this same problem, started out once a week, moved up to a few times a week, then finally when it was a few times a day I went and got a new sim. They told me if this doesnt work bring it back in and they will give me a "new used" phone.
2 weeks without the issue, phone bumps the nightstand a little too hard and starts happening again.
I pulled out the sim tray, cut a piece of packing tape to match its shape. Put the sim in and layered the tape over it. Seems to have resolved 99% of my "no sim" issues. I say 99% because it happened once in about 6 weeks since I taped the sim in place.
