We have already answered some questions regarding the Galaxy S3 “No SIM” card problem and errors related with it. However, the information we’ve provided wasn’t enough especially for non-savvy users pushing them to send us email asking us to provide more detailed tutorial on how to solve the problem. So here it is…
Overview of the Problem
No SIM card error on the Galaxy S3 is not really a serious problem, however, it occurs indiscriminately. So anyone who has the phone can experience this problem anytime, anywhere. Another thing is that, nobody knows when the error pops up. The worst case scenario would be if the user is in a place where he or she has no access to other SIM packs when this problem occurs.
There could be a lot of factors that may result to No SIM card problem. Fortunately, majority of users who reported to have experienced this problem said the issue can easily be resolved. So, if you are experiencing this issue right now, it could be because of one of the following:
Phone Load Time – every time a smartphone is turned on, it loads a bunch of drivers and services necessary to run all system apps. However, there are times when the phone loads a little slower than usual and that could be the reason why the SIM card is not detected immediately.
Loose Connection – if one of the pins cannot touch the interface on the SIM card, the system reacts immediately popping the No SIM card error window. It is actually one of the most common problems cellphone users can experience.
Corroded Interface – over time, the SIM card’s interface will accumulate dirt for some reason. When this happens, the pins and the connector couldn’t establish a good connection that would lead to the problem.
Damaged SIM Card – this isn’t a rare problem, in fact, many of SIM card-related problems were caused by damaged SIM packs. If you’re tied to an operator, one call to the hotline could solve this problem.
Damaged Phone Connector – of all possible causes mentioned here, this one’s rare but it doesn’t mean it couldn’t occur to you.
Solving No SIM Card Problem
The best thing for any use to do when this error occurs is to use the elimination process in determining what caused it.
Try rebooting your phone first and wait until it’s fully active to see if it still displays the error.
After a reboot or two and it still persists, turn the phone off and open the back panel. Take the battery out and then the SIM card.
Using a soft and clean cloth, gently rub the SIM card’s connector to clean it. Re-insert it and turn the phone on to see if the problem was solved.
After doing the above steps and the error still shows, it’s time to use a bit of unorthodox way. Try to see if you can insert a small piece of paper between the tray and the SIM card. Doing this will push the card a little more onto connectors. If it were a loose connection causing the problem, this step can solve it.
Test the card with other phones and see if it works. If it does, then there isn’t a problem with it, it’s the phone. But either it is the phone or the SIM card that has a problem, you need to call your provider so the card or the phone would be replaced.
The first four troubleshooting steps can actually be done within five minutes and in that span of time you can figure out whether to call your provider or not.
