Part 1: What To Do Before You Switching SIM Card

Whether your iPhone is brand-new or you've been using it for some time, you must check three crucial things to ensure your iPhone data doesn't get lost during the process. These include the following;

1. Check if iPhone is Carrier Locked:

Before changing your iPhone SIM card, you must check whether your iPhone is network unlocked. Yes, this is because some iOS devices are usually locked to a particular service provider, thus making it impossible for users to use a SIM card of another network on the device. To check if your iPhone is carrier locked, you have to follow the procedure below;

  • Open Settings on your iPhone.
  • Tap General and select About.

  • On the About page, scroll down to Network Provider Lock to see your iPhone network carrier lock status.

Note: If your iPhone is carrier-locked, you need to unlock it. You can unlock it by either using a third-party network unlocking service or just reaching out to an authorized network provider's shop.

2. Transfer Contacts stored on your SIM card to your iPhone

When changing a SIM card on iPhone becomes necessary, It's always advisable to transfer contacts saved on the SIM card to iPhone. It'll make it easy for you to access the SIM contacts on your iPhone even after changing it.

3. SIM Card Must be Compatible With iPhone

Apple iOS devices are compatible with only nano SIM cards. So, if the SIM you're looking to use is not nano, you can't use it with your iPhone. Therefore, we advise you to always check the SIM card type before purchasing.

Part 2: What Happens if You Switch SIM Card

Although many people think switching SIM cards on iPhones will cause data loss and prevent them from getting access to specific services, the truth is nothing of such happens. When you switch to a new SIM card on an iPhone:

  • You can start using a new phone number to make calls and send SMS messages.
  • You will be able to use WhatsApp. Changing your SIM card doesn't mean you'll lose your data.
  • Your contacts, app, music, photos, and other data not stored on the SIM card will remain accessible. The only data that will be deleted is your old SIM card account information.
  • Your Apple ID and iPhone settings are not affected.
  • You can still use FaceTime and iMessage. However, you need to re-activate them. To operate, you have to do the following;
    • Open the Settings app, select Messages, turn off iMessage, tap Settings > FaceTime, and turn off FaceTime.
    • After that, restart your iPhone or iPad, go to Settings again, and turn on iMessage and FaceTime.

Part 3: How to Remove and Insert SIM Card in iPhone

Removing and inserting a SIM card in iPhone is very simple. However, you need a SIM card ejection tool for the SIM removal operation. If you don't have one, you can use a paper clip. The following steps explain the process.

Step 1: Get your iPhone and switch it off. It is always recommended to do this because ejecting a SIM card from iPhone without turning it off could damage the tiny processor of the SIM card.

Step 2: Find the SIM card tray section at the side of your iPhone and insert the SIM card ejection tool into the tiny hole. By doing this, the SIM card tray will pop out.

Step 3: Gently remove the SIM card tray and change the SIM card. Make sure you place the new SIM card correctly. After that, insert the SIM card tray with the new SIM where you removed it.

Step 4: Turn on your iPhone to start using the new SIM card. It's as simple as that.
