SIM card not recognized in Samsung Galaxy S9 plus
You just bought a Samsung Galaxy S9 plus and when you start it it gives you the following error message: SIM card not recognized. It is common that the Samsung Galaxy S9 Plus does not recognize the SIM card and announces this message. In this case, it is not really necessary to inform the Samsung Galaxy S9 Plus directly. Actually, there are several tips to fix this malfunction, so we will see in this tutorial what are the things to do and control so that the SIM card is recognized on the Samsung Galaxy S9 plus.
What to do when the SIM card is not recognized on my Samsung Galaxy S9 Plus
If the SIM card is never recognized on the Samsung Galaxy S9 Plus, here is a list of tips that will help you identify the causes of the malfunction and why not fix the problem.
Clean SIM card
One of the first things you should do when the SIM card is not recognized on the Samsung Galaxy S9 Plus is to clean it. In fact, it is common for dust to block the contact between the SIM card and the smartphone. To remove the dust, put a small cloth on it and check if it is not damaged.
Check the location of the SIM card on the Samsung Galaxy S9 plus
Sometimes the malfunction can come from where the SIM card is placed. In practice, in most cases, the mini metal plugs that should come into contact with the SIM card loosen a bit if everything goes well. If so, this prevents the Samsung Galaxy S9 from reading the SIM card anymore. To solve this problem, simply thicken the SIM card by adding one or two pieces of adhesive to the back.
Try the SIM card in a second smartphone
If you want to know if the malfunction is from the SIM card, you can try it on a second device and you will have your explanation. If it is not recognized on other devices, you will need to replace the SIM card.
Try another SIM card in the Samsung Galaxy S9 plus
Assuming that the previous two phases do not work, simply try another SIM card to see if the malfunction comes from the card. And yes, if other SIM cards are recognized in the Samsung Galaxy S9 Plus, it implies that the problem comes from the card. Otherwise it’s up to the laptop to look at.
Make sure your Samsung Galaxy S9 Plus is not a Simlocker
If you have ever tried multiple SIM cards in your Samsung Galaxy S9 Plus and none are recognized, it is possible that your smartphone is Simlocker. This means that the Samsung Galaxy S9 Plus can only recognize SIM cards from a certain carrier. In that case, you need to unlock it. You will easily find many offers on the net that can do that.
Note that the problem does not come from the ROM installed on the Samsung Galaxy S9 Plus
This part is of particular interest to people who have rooted the Samsung Galaxy S9 Plus to install an aftermarket ROM. If this is the case for you, keep in mind that SIM card not recognized issue is quite common after installing a ROM. Therefore, we recommend that you reinstall an original ROM and try again.
if nothing works
In case all the above solutions do not work, we recommend that you take the Samsung Galaxy S9 plus and the SIM card to one of your operator’s stores.
