I am getting following error when I try to use my Mio a700 phone.
"Invalid or missing SIM card. you can still make emergency calls if your service provider supports it."
It was working fine till yesterday, but suddenly from today morning its giving me above message.
When I try to put this SIM card in another phone its working fine.
Its not working on my MIO A700 phone.
Can anyone please help me.
thanks a lot,

Hi all,
I have an Iconia A501 which was sent me from the customer service in exchange of another one with bad pixels. Yesterday, for the first time, I put my simcard in the slot, then I got the usual message "Simcard inserted or removed, the tablet will restart". Then it restarts itself, but I still get "Insert a SIM Card", just like it wasn't there. So, basically, the tablet can recognize when I insert or remove the sim card but then it's not used. I'm in Italy and, AFAIK, it shouldn't be SIM locked since the old tablet was working fine. I also tried with other sim cards, of various carriers, but nothing works. So, the question is: is the internal 3G modem dead? What can I do to investigate the issue? I tried with two roms, Taboonay 2.2 and Harkon 1.0, which both should support the internal modem.
Thanks for any clue.

Check your build.prop file,and make sure it has a # in front of ro.carrier=wifi-only.Should be at the end of the file.
Or, you can just check to see that you have the wireless 3g menus in the settings.
Make sure the sim is oriented correctly in the slot. there is a very tiny image to show how (unfortunatly it took me 10 minutes to figgure this out)
Don't insert it with the tab on. Might explain the reboot. Never tried it, just a guess. Might even cook the sim, one never knows.
Go back to recovery, do your 3 mandatory wipes, and try Harkon rom. It's a 501 specific.
I get the message every once in awhile but usually a reboot fixes it.
You may just need to reverse your steps, remove with tab on. Shut down. Reboot. Shut down and insert sim, then boot it up.

With the old tablet I didn't need to shut it down before inserting the sim... so i can't se why it should be needed now everything rom related doesn't help too, I even de-rooted, even list CWM, and yet it doesn't work.

If you read the instruction manual it actually says to insert the sim/ sd card while the Tab is OFF - DON'T INSERT WHILE POWER IS ON...
Now I know its fun to try things out, however, when it comes to things of this nature I tend to follow the instructions...
Why not give it a try and see if it works. Look at it this way, it couldn't hurt...
Ok... I turned off the Tablet then inserted the sim and turned it on again. Guess what? Nothing changes The sim is still not recognized. I called the tech support and the tablet is going away for repair/substitution tomorrow
I know this issue has been spoken of in other posts, but nothing exactly like the issue I am having and all I have read are not with the s4
I am on factory stock Rogers firmware. I337MVLUAMG1 unrooted. "Not registered on network" is keeping me from doing anything. I can access wifi and all my APN settings are correct. Nothing in my phone looks wrong or out of place.
I have tried 2 new sim cards and that certainly isnt the issue.
My imei and serial are reporting a.ok
Phone was unlocked from rogers and previously being used with bell all with no problems.
I did try some custom roms before heading back to this and thinking perhaps something got screwed up. I inserted my sim after installing omega rom v11 and it has not worked. that was the first time I even tried a sim in the phone. So it has never worked since I got it. Which sucks because I don't know if it was something I did or something that was already in place.
I have done a factory reset with data from settings in the phone and also from stock recovery.
I have removed the battery, sim and restarted. Doesn't help.
Phone says "not registered on network" when trying to make calls and says unregistered sim card when dropping down notification bar.
Any ideas? Help? ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
Edit: Ok, after some heaving reading I think the issue lays with the update to Omega v11. I think it changed the efs file structure to a new format and I need to use a newer modem to access it the new format properly.
Can anyone please let me know an mg4 or acceptable modem that would allow me to test this theory and if I can just flash the modem with the stock firmware.
Once again its an i337m currently running rogers I337MVLUAMG1. IMEI + serial working fine but no network access. Looking for a modem that will work with this setup to see if I can access a modified efs folder.
Information of modified efs was read here - http://forum.xda-developers.com/showthread.php?t=2377731
I had this problem and in my case was because a bad sim unlocking. So i just tradedy s4 for another one already sim umlock

Interesting... hadnt heard of a bad simunlock. good to know!
Any other options?
Answer...... NO!
!!!LESSON TO BE LEARNED HERE! BACK UP YOUR EFS FOLDER!!!!
If you are reading this and never done it... DO IT NOW!
It is a simple thing to overlook. I have been flashing roms for over 2 years and not once have I back it up... New S4.... not so good. Just sent for repair.
Now I wait to get the phone back so I can play with it again
BACK UP YOUR EFS
So, I broke my S4's screen and had it replaced by Samsung. After that I couldn´t make phone calls through my network, I couldn´t hear anything and no one could hear me. But by using whatsapp everyhting worked fine. Also my phone stopped recognizing my SIM from time to time.
So I swapped my SIM card and it didn´t work. Then they told me the problem could be with the SIMS slot, and so I had it changed, and amazingly still nothing. And so their solution was to change the Phone's motherboard for a lot of money! Since the problem didn´t seem like hardware, I flashed a new ROM through Odin.
The SIM is recognized (it wasn´t anymore) but there is still no sound on phone calls. Any ideia? could a rooting, and installing a TWRP and flashing a new ROM work?
Thanks

Try to flash a custom ROM and see what happens
If it fixed you problem then the stock ROM is a little bit corrupted
If not then try to replace sound module of the device[emoji6]

I've been using my Nexus 6P without problems for a while now but suddenly I this morning I lost service. Tried the following:
- restarting the device
- searching for other operators (just comes up with Error while searching for networks)
- put sim card in another phone (it works)
- put another sim card in my phone (it doesn't work)
- factory reset
So far, nothing has seemed to work to get back my service. I'm running completely stock everything, unrooted, haven't even unlocked the bootloader. Any ideas what might be wrong/what I can do? I'd like to try as much as I can before I have to go back to where I purchased it from.
Did you find a fix for this?
I have the same problem with my 6P.
I have a similar issue. Mine will start and be connected for about 10 mins, and then it tells me the sim has taken to long to respond, and that it is locked.
I ordered a new sim card, but I would like a short term workaround.
I have exactly the same problem, too :'-(
Any way to fix this?
Are all of you running stock or a custom ROM?
Did you recently install any updates?
Did you recently restore from a TWRP backup?
More info is needed to try and diagnose this.
I had the same problem one month ago. It's not a software problem, it's a hardware. I did exactly the same steps as you and I flashed also stock images, but nothing helps. So I send it to service and they replace the motherboard.

Hi, I've had some issues with SIM cards in my Mi A1.
I've tried rebooting and I've tried both SIM slots, but neither of them are detected. "No SIM card - No Service" shows at the top of the screen. There's nothing wrong with the SIM itself, it works fine in my old phone (a Redmi Note 3) so I'm not sure what to do now. Everything worked fine yesterday and I haven't dropped it, splashed it with water or anything since then.
Any help would be appreciated, thanks
hello brother please imei number check
hey
I'm having the same issue. How do you fixed it?
Thanks
I had this issue too, try restarting the device 2 or 3 times. If it doesn't work, try doing a factory reset.
was anyone able to fix their SIM issue?
my Mi A1 received an OTA update last month and the "SIM card not detected" msg
when I check my Network Settings, the menu options are all greyed out and i can't do anything with it
i've tried flashing many different versions of stock/custom ROMs
i've tried a variety of different SIM providers (Rogers, Koodo, Fido, etc)
i've even flashed a few modem versions to see if it would fix the signal (cuz that's how i used to fix my SGS2)
but nothing works... it's behaving as if there isn't a SIM card inserted at all
...which is leading me to believe that this could be a hardware failure
anyone with suggestions on how i can fix this? cuz otherwise, it's a great device... it runs AOSPExtended like a champ
thanks in advance
