Sim Card Issues - Galaxy S III Q&A, Help & Troubleshooting

Yesterday I received my Galaxy SIII, inserted my microSim from my Nexus and started it up.
However, during the setup I got a message saying my sim card was not detected. I finished the setup but even though it shows that I have reception and it is unlocked, I can't send messages, use data or make calls because it says there is no sim card in the phone. I am on the stock rom, rooted and I'm on 4.0.4 with Baseband version I9300XXLG8.

Turn it off, remove sim card, wipe sim card with cloth, reinsert sim card, power on.
If that doesn't work...
Turn it off, remove sim card, throw away sim card, get new sim, insert sim card, power on.

[Q] SIM card not detected

Hello
My SGS3 gti9300 is not detecting my SIM card, it was fine this morning, i used my mobile data without any problem but as soon as i switched my mobile data off, my phone lost network. It tried pulling off the SIM card and putting it back in but in vain; my phone would read the SIM card, it says 'No service'. I also tried checking my IMEI number by *#06# on the dial pad, it would display 'null / null'. I do not have any other micro SIM card right now to try in my phone. My current SIM card works fine on other phones...so i guess the problem is in my phone
Besides, later when i played music on my phone, the music would stumble and at times the track changes by itself. That problem came along with the SIM card one.
My phone is not and was never rooted. It runs on Jelly Bean.
Please help me fix at least the SIM card issue :crying:
If your phone is fully stock and never rooted then return to Samsung for warranty repair.

It's look like a problem with efs. Search on forum how to recover efs files.

[Q] Confirmation that sim slot is working?

Hello all, i just bought one of these phones on ebay. Im not sure if the SIM slot if working. I put an inactive T-moblie and also an old AT&T sim card in there, but the lock screen shows "No SIM card" with a picture of a sim card with a red exclaimation point underneath that it says "no sim card inserted emergency calls only". I wanted to activate it on T-mobile or Straighttalk, but before i buy a new sim with a months plan i'd like to make sure that its working. Does the phone show this message with an inactive sim card inserted? or only when there is NO sim card inserted. Thanks for any help.

I have two amazes. One had a broken SIM slot. The other was normal.
The one with the broken SIM slot showed the no SIM card even when I used my good SIM card.
One of the guys from the forum sent me the phone to tinker with along with the $9 part. I fixed it and now, with an old non active SIM card in it it shows a cell signal. But no data.And when I try to make a call it goes straight to T-Mobile.
It's a very easy fix if you can get the party and the tiny torx driver to remove the screws.
How much did you spend buying the phone?

Get a new SIM first, then a new SIM slot replacement if it doesn't work.

Check with T-Mobile first, you might need to get a new SIM card.
If a new SIM does not fix the issue, just go with Chevy's suggestion and buy a new SIM part from ebay.com. Make sure you use the right tools, and an anti-static wrist strap may help! :good:
If you bought an Amaze at this point in time for over 130$, you probably didn't get the best deal considering how it isn't working right. I really don't understand why people still are buying Amazes when there's much nicer HTC phones lol.

Is a SIM card required

Does the rezound require a SIM card for service, I just bought this phone and it does not have a SIM card, keeps asking me to put it in, I know my old DINK2 had a sim card, and I took it out, I did not have to have it.
This phone will be flashed.

Emergency call and no service

My lg g5 dual sim variant recently stop detecting my sim card. Have not ejected sim tray for months and have checked through threads after threads for solution. Micro sd card is working though.
-Changed a new sim card
-sim reader( repaired by reputable shop)
-Did factory reset before repairing
Sometimes my phone detects the sim and starts rebooting. And follow with a rebooting loop until sim is ejected. Sometimes it detects the sims and my service provider but no calls, msgs and mobile network can be used.
Is there anything i can do? I love this phone.
Thanks!

Sim Card disabled

Hello,
I brought realme 1 in Delhi a few days earlier. I left India and I am currently living in Nepal. When I tried to put the Nepalese sim card, it says your phone is customized. The phone is not accepting the sim card and the sim card remains in disabled mode. Is there any alternative to enable the sim card? Looks like I am in big trouble.
