Things You Should Know About Switching SIM Card from Android to iPhone
Last Updated on November 3, 2023 by Ian McEwanIf you have decided to ditch Android phone for iPhone, you may be grappling with the problem of how you will transfer your contacts or other data to your new device. Android phones run on a different operating system to that of iPhone and thus certain aspects may be incompatible between the two devices.
Regardless, one thing that works is switching SIM card from Android to iPhone to transfer contacts. Find more about it below.

Part 1: Can an Android SIM Card Work in an iPhone
If the size of the Android SIM Card fit the iPhone SIM card slot, then the answer is yes. That means your Android SIM card should be the size of the target iPhone's SIM card tray. For a better perspective, here is the list of iPhone and iPad with the size of SIM card it uses.

SIM Cards are independent of the operating system running on a device. In fact, the SIM card itself has its own microprocessor and a memory (64 kilobytes (KB) of internal memory) to store information such as contacts, text messages, subscriber information and algorithms to encrypt subscriber authentication data when the subscriber tries to make calls.

So you need not worry on compatibility issues of your SIM card. As long as the SIM card has the same size dimensions as the slot provided, then the rest should not be a big issue. The iOS operating system will just detect the SIM card once you switch on the iPhone.
If the Android SIM Card doesn’t fit, you can get one from the carrier or have it physically resized if possible.
Part 2: What to Do before Switching SIM Card from Android to iPhone
Copy SIM Contacts
Before switching SIM card from Android to iPhone, you can copy all the contacts in your Android device to the SIM card. However, you can only have a maximum of 250 contacts stored in your SIM card due to the limited storage. If you have more than 250 contacts, the next best option is to use an Android-to-iPhone transfer program.
If your contacts are stored online, you will need a network connection to successfully copy all these contacts. Another way to do that is use your Google Account to save the contacts and sync the same account to your new iPhone.
Get Your Favorite Apps
You need also not worry about how you will get your favorite apps on the iPhone device. Most of the apps in the Google PlayStore can still be found in Apple’s App Store. You will also get access to free iCloud storage which is similar to the Google Drive storage.
The only drawback is that the iCloud storage provides a storage capacity of only 5GB compared to the Google Drive storage of 15GB. However, you can still benefit from Google Drive storage while still using the Apple devices.
Check Accessories
You should also note that some of the hardware devices which come with Android devices are not compatible with the iPhone. Thus, there are certain accessories which you will not be able to reuse with your iPhone device.
Some of these may include the charger, data cables, OTG cable, earphones, and other accessories. But before ditching some of these hardware accessories, double check their compatibility.
