SIM Failure

A couple of weeks ago my phone started generating an SIM error message at startup.
I then changed ROM from the Orange WM6 to the latest HTC version, and since then i get the same error message.... Missing or invalid SIM please contact you service provider....
The weird thing about this is that I still get the error message, I clear it twice, and it asks me for my PIN and continues to work just fine... I thought that changing the ROM would sort this as I just put the error down to some sort of OS problem initially.
Anyone else experienced the same of similar issues?
I replaced my SIM to see if that made any difference but that hasn't changed a thing either...
.G.

the same here. don't know why..

hi! ive had alot of experience with phones giving similar errors. found its one of two reasons..
1) the phone is blacklisted. its weird but blacklisted phones works sometimes and other times it gives some sort of invalid sim error.
2) the sim is just simply not making proper contact with the metal pins. in nokia phones i usually just put a small piece of cartboard or thick paper in between the battery and the sim and the pressure forces the sim closer to the pins.
dunno about vox tho. put its worth a try

I get the same problem, with an O2 SIM card in a HTC-branded S710. Sometimes it happens, and sometimes it doesn't.
If it happens while turning the phone on, then I find that all of the sounds are playing faster than usual also (things like message and call tones are high pitched). If I go into Comm Manager, put it into flight mode and back out again, it not only finds the SIM card properly but also fixes the sound issue.
I wonder whether it's something to do with my SIM card possibly being a USIM card instead, since it says "O2 3G" on the card, but of course, the handset is not 3G-capable.

My excalibur (HTC 620) phone has exactly the same symptoms with a USIM (3G). It has no problem with other 2G SIM.
I am not sure whether it is something with the ROM. I flashed my phone with wm6.1 rom cooked by Kavana.

I had the same issue with one of my 3G SIM's. Eventually I didnt know what else to try so I got a SIM swap and thats solved the issue. Not a single problem since then

[Q] SIM card error! Please Help

So out of nowhere today, i awaken my phone and I see an error "SIM card removed, reboot phone" I reboot the phone and now I have no signal and a SIM card symbol in the notification bar. I didnt remove the SIM so I dont know what happened or how to fix it. Anyone know how to fix this?
EDIT*** Nevermind. I removed the sim, then put it back and that solved the problem. Probably should have tried that before posting lol

happened to me a week ago. I was puzzled. I removed the sim and battery at the same time like 10 times. So I flashed back to stock and took it in. The guy plugs the phone in (probably checking for root) and then unplugs pulls the sim and battery and turns it back on. All working like nothing happened.

No Sim issue?

Okay I have a very interesting situation going on. So I have the Rogers GS2 LTE. Had it unlocked over a year ago. Anyway this weekend I decided to upgrade my step daugher's Captivate with the GS2 LTE. we are both rogers customers on the same account. Anyway, i put her sim card in the phone. and noticed that it wouldn't boot. Finally it booted but got the no sim card error. so I thought that was weird and used ODIN to go back to stock. Still had the issue. Went to Rogers and got a new SIM card for her phone and still got the error.
Then today at work, I was playing around with the phone but only had my Speakout sim card with me. I was in the service menu and i was frustrated so I just started to push buttons and low and behold it reconized the sim card and started to work. I must say I was very pleased with myself that I was able to get it working. (nothing recorded on what I did of course). So i set up the phone and download most of her apps, thinking how great it was that I was able to fix it.
Well I get home and proceed to put her SIM card in the phone. "No Sim Card" again..... So thinking that I screwed it up. I put the speakout sim back in and it works fine. (Speakout runs off rogers towers). I can swap them and rogers won't work but speak out will. now the funny thing I noticed is that with speakout it always shows my data connected at 4G even when I know speak out doesn't offer 4g and we don't have any 4G/LTE near my home.
So I am really at a loss. Since it works with speakout I know it's not a hardware issue. Unless it's a really messed up hardware issue. which only leaves me to the idea it has something to do with that service menu. Now what I am going to attemp is to flash back to stock (rooted her after I thought it was working properly) and then try playing with the menu again.
Either way this is one really messed up phone lolol So anyone else have any suggestions?

Okay so the saga continues.
Yesterday I again did a firmware upgrade via "Kies" and noticed that the phone was getting signal, so i made a test call and it went through fine with the rogers sim. Then all of a sudden went to "No sim inserted" again. Today applied the firmware update again and now i get an initial message of "the mobile network will be unavailable until you restart with a valid sim card" and then the no sim inserted.
This is really starting to drive me crazy lol
Any suggestions? might try taking it back to Gingerbread and then maybe ICS to see if that has any effect. Any other suggestions?

Hey everyone,
Still trying to figure this out So i can make the phone recognize the sim card by doing the following:
*#197328640#
[1] DEBUG SCREEN --> [8] Phone Control --> [5] Simulation --> [3] HW Watchdog wait about 30 seconds then press [1] Force CP Crash.
After this, it seems to dectect the speakout sim card again and work. However after a reboot the sim is not detected again. So from my thinking it's not a hardware issue. i.e. I don't need to replace the sim card "Card" so to speak. What do you all think?

Actually i just tried this again and it doesn't always work. So i'm still at a loss on what the issue is.

network disappearing

So recently I installed xposed on my VM moto g 3rd gen wit cm13 an I decided I didn't want it anymore so I uninstalled it an now a message pops up an says my sim isn't responding an I can only fix wit for about 10 mins upon my boot wit a APN fix. Any ideas on how to fix it?
An I have an old sim I used before I got this phone in my HTC desire 510 should I take that sim out an activate that sim an see if that works? Cause like after 10-15 mins my service completely cuts off an says invalid sim

This is what pops up

N5 has No service, No data and SIM card sometimes not recognized

Heres whats going on
I have reset the N5, and flashed the July MM image. Everything flashed fine.
I insert SIM before booting, Android doesnt see SIM... so i pulled out the SIM and reinsert while on, and it sees it.
The Signal goes into an empty triangle... It says you have voicemail. And nothing else happens.
No data, no service. *#*#4636#*#* shows the right selection, it gives me the option to turn on the radio, but if i click it, nothing ever happens.
Under phone info, it sees my phone number, the IMEI is fine, and its not blacklisted when i check multiple carrier's websites.
I just cant seem to figure out why it wont just acquire service signal even when APN settings are right.
Anyone got any tips, tricks or solutions to this?

Possibly damaged sim card or sim card reader?

dont think so, i think its software maybe.... When i do *#*#4636#*#* it will show my phone number on the top... if i remove SIM, the number becomes "unknown"... so i dunno

If it happens with all SIM cards, it could be a damaged sim reader as different areas of the SIM card contains different information? Not sure.

I have similar problem with MOB30P on T-Mobile network. The 4G LTE would work just fine (I can browse web etc), but the voice is where it is failing hard. I would have dropped calls along with calls not coming through (both calling out and receiving calls).
I downgraded to MOB30M and everything appears to working fine now. I have not opened any bug against Android yet, because I am not sure if I am the only one experiencing this problem.

Hi, I was googling for a problem like your one. My N5 does not recognise the sim at boot, but only if it is "hot". If I put it in the fridge for ten minutes and then reboot, all works fine until the next shutdown. I'm sure it's an hardware problem (already tried different sim) so I disassembled all the phone, and it looks perfect. With some cleaner for electrical contacts it can survive for some days, and then starts again. So sad, I don't want to change phone just for this stupid problem XD

I'm getting exact same issue with my Nexus 5 since CM13 0803 update, which brings MOB30Y to my phone I believe.
At first my phone could still recognize my carrier (China Unicom), but there is no signal.
Then I flash radio image from MOB30Y and the phone now cannot find SIM card completely.
Even reflashing factory image doesn't help.
I'm now trying to reflashing MOB30P to see if it helps.

Update to latest August security update radio and bootloader
