Part 1. What Is SIM Card? Do You Need to Transfer SIM Card to New iPhone?

Do you need to switch SIM cards when changing iPhones? Yes - because they contain important information you were using on your older device. SIM cards not only help for communication purposes and using carriers but also keep important information such as phone numbers and security data. You can use a SIM card of any size and insert it into your device. But make sure it matches your device's model. Adapters are also available to help insert the nano SIMs into micro SIM cards or the normal SIM slots.

The different types of SIM cards available are micro SIMs, Nano SIMs and eSIMs.

  • Micro SIM: This SIM card is smaller than the original SIM cards. The actual chip is just the same size as the original SIMs, with only the area around it smaller. It was first used in the iPhone 4.
  • Nano SIM: This SIM card is smaller than a Micro SIM card. It is called the 4FF, the fourth SIM card generation. It's a fraction of the original SIM card and very small than the second SIM card generation. It debuted on the iPhone 5.

Part 2. What Should Be Considered Before Switching SIM Card to New iPhone?

If your device is new or you have been using it for a while now, you should check for some crucial things to ensure the iPhone data does not get lost while switching. Here is what to do:

Tip 1. Check If iPhone Is Carrier Locked

Before changing your iPhone's SIM card, you should check if the device is locked to a network. You should do so because some of these iOS devices are always locked to a service provider, which makes it impossible for the users to use the SIMs on another network on the same device. You can check if the device is carrier locked by doing this:

Step 1: Open Settings on the iPhone and click General. After that, choose About.

Step 2. Scroll down the About page until you reach the Network Provider Lock and check for the device's carrier network lock status.

Remember, a carrier-locked iPhone must be unlocked. You can do that with the help of a third-party app or by contacting a network provider shop.

Tip 2. Transfer the Contacts on SIM to iPhone

While changing SIM cards on iPhone, it is advisable to transfer all contacts that are saved on SIM to an iPhone. This will make it easier to access the contacts saved on the SIM card on the other iPhone.

Tip 3. Ensure the SIM card Is Compatible with the New iPhone

iOS devices are only compatible with nano SIMs. Therefore, if you are looking for a SIM card other than a Nano, you will not use it on your new iPhone. You should check the type of your SIM card before buying.

Part 3. How to Move SIM Card to New iPhone [Direct]

Moving SIM card to new iPhone is pretty simple. But you shouldn't try moving it without the SIM card ejector tool. Usually, the ejector tool comes with the phone when purchasing it, or you can use a pin instead. Here are steps to putting an old sim card in the new iPhone:

Step 1. Take your old phone and switch it off. Find where the SIM is located and use the ejector tool to remove it from the device. Clean the SIM using a cotton cloth.

Step 2. Next, take your new iPhone and find the SIM tray. Use the SIM ejector tool to press in the small hole on the side of the iOS device. The SIM tray will be removed from iPhone.
