Is A SIM Card Required To Download Apps?

A SIM (Subscriber Identity Module) card is a small portable chip whose main function is to store information about the phone user, as well as establish communication between  the phone and the carrier’s network. 

If you’re using your smartphone with Wifi without a SIM card, you may wonder whether or not you can still do things such as installing apps from the app store.

Do you need a SIM card to download apps on Android?

A SIM card is not required to download apps on an Android phone. The following sections will explain how to install apps from the Google Play Store or outside of it, without the need for a SIM card. 

Downloading apps from the Google Play Store

You can access Google Play Store and download apps from it provided you are logged in to your Google account on your Android device. 

You will need to be connected to the internet through Wi-Fi or a mobile hotspot to access the Play Store. Using mobile data through a SIM card is not required to access the Play Store, a wifi connection works just fine.

If you’ve created your Google account with phone number verification, you might be asked to verify your account through your phone number when you sign in to your account.

A code will be sent to the number you provided via text or voice call and you will need to enter that code on the log-in screen on your device. In this case, you do need to have a SIM card associated with that number to sign in to your account on the device.

However, if you have created your Google account without phone verification, you can sign in using your Google account address and password on the Android device. Here, access to the Play Store and downloading apps doesn’t require a SIM card.

Downloading apps outside of the Play Store

Downloading apps outside of the Google Play Store in the form of APK (Android Package Kit) files doesn’t require a SIM card.

If you have internet access on your Android phone via Wi-Fi or a mobile hotspot, you can download an APK file using a browser such as Chrome. Here is how to do it:

  1. Navigate to Settings > Apps & Notifications >Special App Access > Install Unknown Apps.
  2. Tap Chrome or any other browser.
  3. Toggle on “Allow From This Source”.
  4. Visit a reputable APK download website (such as APKMirror) in the browser and search for an app that you want to download.
  5. On the download page, tap on the link to download the APK file.
  6. Go to Downloads on your device > tap on the APK > choose install 

Can I download apps on an iPhone without a SIM card?

You can download apps from the App Store on your iPhone without a SIM card provided your phone is connected to the internet, e.g. through a wifi access point.

To download free apps, you need to sign in with your Apple ID on your iPhone. You can then open the App Store and download the apps.

Is a SIM card required to download and play games from Windows / Microsoft Store?

If you still use a Nokia Lumia phone (e.g. Lumia 1520) or another Windows Mobile smartphone, a SIM card is not required to download and play games from the Microsoft Store (formerly known as the Windows Store).

You can download games, apps and their updates provided you are connected to Wi-Fi. You also need a Microsoft account to access the Microsoft Store on the phone.

If you don’t have a Microsoft account, you can create a new one here. Just follow the steps to  set up the account on your Windows Mobile.

If you own a Microsoft device that comes with Windows 10 or Windows 11 e.g. a Surface, a SIM card is not always necessary to download and play games from the Microsoft Store.

If your Microsoft Surface device (e.g. Surface Pro X) also has a SIM card slot or supports eSIM, you can connect it to a cellular network and download and play games from the Microsoft Store.

If you don’t have a SIM or data plan, however, you can connect your Surface to a Wi-Fi network and freely download apps and games from the Microsoft Store.

You can also connect the Microsoft device to your phone’s Wi-Fi hotspot to gain internet connectivity and access the Microsoft Store, just like you would connect to any Wi-Fi network.

In that case you can insert a SIM card into the SIM card slot on the device and connect to the cellular network. You also need a data plan from a wireless carrier to connect to the network.
