A SIM card is the core of mobile devices. It's crucial to the iPhone's ability to make and receive calls or messages. But, there comes a time when you need to change the SIM card to another iPhone. For instance, you may be traveling abroad, or you've changed devices. No matter the reason, switching SIM cards between iPhones is pretty simple.

If the SIM cards are from different carriers, an iPhone SIM card swap can only happen if the phone is locked to a carrier. With that in mind, let's explore a safe way to switch SIM cards between iPhones. We'll also introduce a supreme tool to seamlessly transfer data from one iPhone to another. Keep reading!

Part 1. What Happens if You Switch SIM Cards in iPhones?

Switching SIM cards between iPhones is a feasible task that will take only a short time. Even though SIM card swapping won't affect your files, it is advisable to create a backup prior. A SIM card can get damaged physically during the process, leading to contact loss. So, you should create a backup of your iPhone contacts before proceeding. (How to change SIM card on iPhone?)

When you switch SIM cards in iPhones, your phone number will change. Your data will not be affected. Usually, a SIM card is linked with a phone number, so changing it will change the number used to make calls or send and receive text messages.

If you are using a new SIM temporarily, you do not have to let people know you have changed your phone number. But, if you wish to switch the SIMs permanently, you must inform those in your contacts of the change in the number. Some messaging applications, such as WhatsApp, will work on your previous phone number unless you delete the app and reinstall it.

The SIM swap will not affect your phone's settings since SIM cards have nothing to do with files stored on your phone. You will not be logged out of your iCloud account, so you can continue using your previous Apple ID.

However, if you face challenges using your iPhone after the SIM switch, check if your phone is locked to a network. If it is, then it's the cause behind such issues.

Part 2. What To do before Switching SIM Cards between iPhones

Here are some things to do before the switch:

1. Check if the iPhone is locked

If your iPhone device is unlocked, it implies it is not tied to any specific cellular network. In this case, it will be easier to switch your current SIM with another one of a different network and start using your new SIM card immediately.

If you purchased your iPhone as new or refurbished from the Apple Store, it is usually unlocked. It makes it easier to use SIM cards from other carriers. As for dual SIM devices, they can use any two SIMs from different networks at the same time. However, before switching the iPhone's SIM, ensure you check if it's unlocked by following the steps below:

Step 1: Open the Settings application, then click on "General".

Step 2: Choose the "About" option, then scroll down".

Step 3: Below the EID number, you'll see a line with the "Carrier Lock" option. If your phone isn't locked, you will see "No SIM restrictions" beside it. However, if you see a message that shows the carrier the phone is locked to, you will only use SIMs from that carrier.

Also, you can insert a SIM card from a different carrier in your phone and see if it will work. And if it works without any issue, the device is probably not locked.

2. Check for SIM Card Compatibility

Another important thing to consider is ensuring the SIM is compatible with your iPhone. Current iPhones use nano SIM cards, the smallest type of SIM cards. If your old iPhone uses a standard SIM card, it will not fit the other latest iPhone model.

3. Save Contacts to the iPhone

A SIM card can get destroyed during the swapping process, meaning all the contacts available will be lost. If you usually save your contacts on a SIM card instead of the phone, you should import them to the phone before the SIM swap.

To backup contacts, click Settings on your iPhone and choose "Contacts". Tap the "Import SIM Contacts" option, and all your contacts will be saved to the iPhone. (How to retrieve contacts from SIM card?)
