14 Ways To Fix Your Android keep Saying NO SIM Card?

Your phone will say there is no SIM card installed or detected when you are making a voice call or sending a text message, or even using the internet. You may not understand why this is happening, but through the article in this blog post, you’ll be able to learn more about why and how to fix your phone that keeps saying no sim card on your Android device.

What Is Android SIM Card?

A SIM card is a physical card that allows mobile phone users to connect to the network operator of their choice. When buying a phone, many people are unaware that they need a SIM card and may instead opt for a contract with their carrier.

A SIM card can be inserted into an Android device, provided it has been unlocked. A SIM card is necessary to use your regular mobile services as it contains your personal details such as your telephone number, service provider, and a subscriber ID.

If you move to another country, your new service provider will likely require you to insert a new SIM card into your phone in order to obtain coverage.

Why Does Your Phone Keep Saying No SIM Card?

If your Android phone says “no sim,” there’s a good chance you’re not using the proper cellular service or your phone is not registered on the network. Here are some common why no sim card is installed or detected on your android device:

1. You’re not using the right carrier. Ensure your smartphone is connected to the correct cellular network provider. Contact your phone company to be sure you’re getting roaming coverage in other countries.

2. You’re not using the right phone or SIM card. Some SIM cards and phones are not well-matched with each other. Make sure you use the proper model of your phone to get your sim working properly.

SIM cards are typically locked to specific carriers, so make sure you’re using the right one.

3. Your phone isn’t compatible with that network’s service. If you’ve tried all of the above and your phone still says “no sim,” it might be because your phone isn’t compatible with that network’s service.

Try connecting your phone to a different carrier or using an alternative type of SIM card to see if that solves the problem.

4. Your Android phone may be blocked from using cellular service due to an active data plan from your carrier or another app installed on your device. Try unblocking the phone by going to;

  • Settings
  • Wireless & Networks
  • Cellular Networks
  • Turning off Cellular Data for all networks

  2. Take off the phone case and check the battery, then search through the internal parts for a SIM card compartment.
