Random sim card missing error??? please help, I'm desperate!!!

Hi everyone... I bought a week ago a brand new Sony Xperia.
It was Vodafone braned but supposingly unlocked.
As I inserted my 3 UK sim-card for the first time the phone could not detect any simcard. After a few soft resets I decided to try with a Voafone card and it worked no problem, so I decided to try again my 3 sim-card and with joy this time everything worked to perfection.
After just a couple of days, all of a sudden the phone started losing the network and giving me a "sim card missing error"... this would happen every time I would activate the flight mode, or simply when the phone would lose signal for some reason... or even just randomly, for no reason. I've tried to flash different radios and different ROMs but the problem stays the same.
I know the sim card is ok as I was using it on an orange HTC touch diamond which I had unlocked and everything was working fine.
I have run the ATCommander and it says SIMLOCK=00 0 which I suppose it means the phone is unlocked...
It's as if the phone was randomly locking itself several times a day for no reason... and the only way to make it work is to soft-reset it about 10-15 times in a row... until it recognizes the sim card and then randomly stops working again a few hours later...
What can I do? Shall I just change operator? Has anyone experienced anything like this? Could 3UK and sony Xperia be incompatible?
Please help, I am desperate!!

[Q] My Note doesn't detect sim card

I`ve bought my galaxy note from Malaysia it worked fine for two weeks
after i traveled to egypt it stops detecting sim card
i`ve tried flashing and changing my modem to EGY
still the same
also i tried 2 edit my nv_data but the same
at least i ordered unlock code but when i try 2 enter it it says mobile network unavailable and it doesn't ask me for the nck code
any help i need 2 use my galaxy note asap
When this happened to me I had to reload a rom.
I allready did
i flashed many roms custom and stock with no hope
the thing i cant understand why it doesn't detect any sim card
i wish someone can explain 2 me what should i do
plz help
i have same issues!my phone works perfect and now no sim card!if you find fix it please tell me
Is your Simcard worn or damaged?
Otherwise try another sim card if that ones work (if your phone is simlock free).
No the sim card is working in another phones
i`ve tried so many sim cards also
plus i dont know if its sim free or not but i already buy the unlock code.
the problem is the mobile can not detect the sim card so it doesnt ask for unlock code
anyone know about the gold card for gnote???
is it carrier locked phone??
if your note got warranty then go to Samsung service center. they may tell you what exactly the problem is.
fyi... Malaysia doesn't implemented Sim Lock/Carrier lock for all mobile phones.
I have the same problem every so often. Without dropping the device or any sort of error, the device does not recognize the sim. I went to my cell operator and got a new sim and it still does the same.
i have try many different sim card and still same issue.my note is sim free model
I figured my problem out. Every time i wear tight pants and the phone is in my pocket and I sit down or drive for a longer period of time, the phone twists and molds after my leg and it shuts down or restarts. For me it's not because of the sim-card.
Was that real

Was that really the fix?
I am have the same problem yet it is in my jacket pocket all the time.. would Samsung repair this if there is a custom rom on it??
I had this issue before flashing the rom I flashed to solve yet it didnt

[Q] My HTC One doesn't see my sim! Help!

Hello everyone,
Yesterday I bought a secondhand HTC One (M7) because my old HOX was giving me headaches..
In all my enthousiasm i have forgotten my one and only sim card tool at the sellers house.
When I got home I immediately wanted to put my sim into my new M7 and tried to open the sim with the back of a needle.
This went wrong on my old One X (I was too deep in the phone with my needle).
I tried it with a paperclip and that worked perfectly. I'm getting to my point now.
When I inserted my Vodafone NL sim into the M7, the phone says no sim. So it appears it doesn't recognize the sim.
The phone came from another provider, so I'm not sure whether its simlock free or not..
When I put the sim back in my One X there was no problem at all, the phone recognizes the sim immediately and works perfectly fine..
So I tried putting 2-5 layers of tape on the back of the sim (yes, I tried 2,3,4 and 5 layers.)
I also performed a factory reset. But nothing seems to be working.... ((((
Is this a hardware failure or can we solve this?!?
BTW I am running stock Sense 6 Android 4.4.2

I had a similar problem, after first update in android 7.whatever my sim card worked but couldnt go online, just via wifi. I could make calls and recieve texts. I got a new simcard and that helped. Later Oreo came and my phone glitched out when i had the simcard installed. But when i took it out it worked. Sent it to nokia support center and got it back today, what happend? Yes the phone works, i can make and recieve calls/texts. But i cant go online without wifi. Asked my provider for a new sim card now, will return and write if that works.
and I have this problem. Have you found a solution?
Weird, my TA-1052 suddenly got this problem yesterday, SIM card state keep looping between detected and undetected, after several loops phone will reboot and reboot again and again.
But when I switch the card to the other slot and reboot, all things seem to be fine. Then at some random time of the day this problem shows up again and I have to switch the card back.
I can 100% reproduce this bug by insert 2 SIM cards together, phone will stuck in a loop and reboot, but logcat shows nothing suspicious.
Tried factory reset but nothing happened.
Since both SIM card slots actually work and I haven't updated system recently, I guess this shouldn't be hardware-related.
