There you go with the question of the day, what is symptoms of a bad sim card?

The major systom of a bad sim card is not being able to detected by the sim slot or the phone itself. In most cases, it shows no sim card inserted or no service depending on the type of phone you’re using.

I want to know if my SIM card is bad or maybe the problem is from my sim slot as it doesn’t detect my sim card.

What are bad sim card symptoms

Bad sim card symptoms is the inability of a phone to detect a sim card, the sim card not showing a network service, sim card failure in a mobile phone, etc.

Now let’s take them one after the other, and below are some of the major symptoms of a bad sim card you should know;

1.No sim card inserted

Once your sim card is faulty, you will be seeing no sim card inserted on your mobile phone. Many a time this error message doesn’t mean that the sim card is faulty, but rather the sim slot isn’t detecting it.

To confirm that the problem of no sim card inserted is actually caused by the sim card, remove the sim card and insert another one.

I mean insert another sim into your mobile.

If it detects it, then you got to know that the sim card is dirty, faulty or damaged. This is one major bad sim card symptoms in a mobile phone.

To fix this problem if the sim card is damaged, you need to go contact yournetwork provider and do a sim swap. By contacting your network provider they will tell you what to do or how to resolve the problem.

However, before contacting your network provider, I will advise you to clean the Sim card chip. Sometimes dirt can prevent a phone from detecting a sim card, so cleaning the sim chip helps a lot.

You need to be very careful while cleaning the sim card chip, use a very clean soft cloth to dust it off. You can damp cloth with water or probably use a rubbing alcohol for the cleaning. Please do this gently and don’t apply any force while cleaning the sim card.

After cleaning the sim card and nothing works, then you have to contact your network provider.

2. Symptoms of a bad sim card: No network detected

Another bad sim card symptoms is no network detected, and this is different from no sim card. In this case, the sim slot detected the sim card but nothing works.

You might think that it is a network issue but usually the problem is caused by your sim card. Wiping dirt from the sim card doesn’t work in this case causethe sim is faulty or damaged.

To be hundred percent sure that it isn’t a network issue but rather caused by your sim card, look around for a sim card with the same network provider and see if it is seeing a network. If it does, remove the sim card and insert it into your phone.

If it does detect the sim card, and there’s a network service, then the problem is caused by your sim card. I’ve seen this type of issue multiple times and that’s why I added to the list of bad sim card symptoms.

3.Phone going into flight mode

If you noticed that your phone suddenly goes into flight mode on its own, the problem is from the sim card. Number of cases has been reported and after a reasonable amount of research it was found out that the problem was caused by the sim card and not the sim slot.

The truth is, some of these problems can be caused by the sim slot especially if the sim slot is damaged. This is why you need to do a test and confirm that the problem is caused by the sim slot or probably the sim card.

Remove your sim fromyour phone and insert another sim into your phone. If you see a network service and it isn’t going into flight mode, then you should know that the sim card is damaged. If reverse is the case, that is your phone going into flight mode, the the problem is caused by the sim slot.

Phone going into offline mode on its own is one major bad sim card symptoms you should know and the only solution is changing the sim card to a new one. We do call it sim swap though it diifers from country to country or network provider.
