[Q] CyanogenMod 7.2.0 Stable, SIM card not recognized - Optimus One, P500, V Q&A, Help & Troubleshooting

I have an LG Optimus One with CyanogenMod 7. Usually SIM cards (Orange Romania) work on it, but when I introduce a SIM card that is only for Internet(Orange Romania), it works about 3-5 minutes, then in status bar shows no SIM. I tested the SIM card with other smartphones but everything works OK. Thank you for reading my post and sorry for my bad english. :fingers-crossed:

[Q] Xoom 3g sim card problem

Wondering if anyone can help, im using team Eos European 3g rom zoom. now i tried 1 sim card and the 3g works perfectly but when i try my other sim, i enter the pin code on screen , it accepts it, then immediately says "Sim card removed, the mobile network will be unavailable until you restart...." .
The sim card definitely isnt broken because it works in my phone and 3g modem on my pc. I've tried restarting the xoom with Wifi off and no luck.
Thanks

how old is that "other" sim card? Reason I'm asking is that sim cards use different voltages and old cards tend to cause problems in modern devices.
Around here, providers usually swap sims for free if you say that you've got a problem with one, so I'd go for an exchange if your sim is older that maybe two years...

Its actually brand new, got it on the weekend. It works perfectly everywhere else. I think i'll go to the provider anyway today and see if i can try a sim swap.
This really is baffling me now. I went back to the providers store and tried a different one of their sim cards and it doesnt work either. I just cant understand why my xoom can read certain providers sim cards and not others? (Its definitely not network locked). Could it possibly be the type of sim card (as in a 32k vs 64k etc)?
Any help would be greatly appreciated

[Q] unable to use 3 sim in Panasonic P-05D

Okay so I bought Panasonic NTT docomo P-05D DisneyMobile. It's unlocked, at least should be BUT my 3 network micro-sim card doesn't work. I tried different cards o2 (one of the 1st sim cards I just cut it and it works - UK) as well as 2 Polish cards Play and Orange which worked too. I live in UK and obviously there is nothing to do that it doesn't work in my country. I want the three network to work.
The phone is 3G phone and the card I use only works on 3G phone which shouldn't be a problem. The card works fine on other phone.
Could it be possibly something wrong with the system that needs to be re-installed or that it might not be unlocked properly?
I really don't want to get rid of the phone, I love it but it's a shame that my sim card doesn't work.

[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

2 sim on EU S8+, possible?

Hi, I recently bought S8+ in Scandinavia/EU and looking at the sim tray, there is a spot for 1 sim and 1 SD card. Is there any way to get 2 sim cards working instead of 1 sim 1 SD?
Thank you in advance

You mean that you don't know if you have a dual sim s8+ or a single sim? It must be written in the back as "Duos"...
I know that this (2 sim & micro SD card) happens in all Duos (Dual sim device)
But I don't think that you can do a single sim version to dual sim
To clarify, the question popped up as I saw some people on YouTube surgically detaching the sim and glueing it to their sd cards in order to get the 2nd sim working. But I assume if there is no actual reader to read the 2nd sim, that operation won't be successful. Thing is, I do not know if there is a reader or not on an European version of s8+?
It's quite impossible since the device must have two imei numbers.

Remove the sim chip from the telecommunications company and stick it behind the SD Card. Look at my photo. Then sim + SD card into the sim2 card slot. This sim2 card slot there sim with sd.
Dual sim on G955F?
Even though not marked on box, is it possible?

The answer is a simple no. Those videos show a dual sim s8 being modded so they can use the dual sim AND an sd card instead of OR.

No. Must have 2 IMEI's for that to work. There is no way to make a single sim phone a dual sim one.

Question SIM card doesn't work when travelling despite working on other phones.

I've bought a Redmi Note 11 Pro + 5G. When I'm in country A, the SIM card works fine. When I travel to country B, the SIM card does not work at all. I've tried going to mobile networks to try to register it on an available network, but it says it isn't allowed.
This same SIM card, placed in another Android phone (Samsung Galaxy A52S), works perfectly fine in both countries.
Is there anything I can do to get the SIM card to work in both countries on my Redmi? Can I flash some ROM or change something about the phone to get it to work?
Is a Miui bug i think, I have the same problem when I travel with mi Main SIM (with a secondary SIM of the same company it doesn't happen to me), tomorrow I flash Xiaomi.EU to test if it still works badly.
Very interesting. I'm thinking about travelling abrod, so I'm following this thread...
Thanks for keeping us up to date!
