(But some older models may use different sizes like micro-SIM or standard SIM.) This allows you to transfer your mobile service and phone number to the new device, including your phone numbers.

Part 3: Preparations before Switching SIM Cards between iPhones

"Can I put my SIM card in another iPhone without causing any inconvenience?" Definitely! But before switching SIM cards between iPhones, it's a good idea to make some preparations to ensure a smooth transition. Here are some recommended steps:

1. Check compatibility of SIM card

Please remember that iPhones produced since 2012 utilize nano-SIM cards, which are currently the smallest available SIM cards. This distinction is noteworthy as there are still smartphones in use that require micro-SIM cards. When purchasing a SIM card abroad, exercise caution to avoid acquiring the incorrect type for your iPhone.

2. Make sure your new iPhone is not locked

Before attempting to use a SIM card from a different provider, please ensure that your device is not locked to a specific carrier. To check if your iPhone is unlocked, go to the "Settings" app on your iPhone, navigate to "General", then select "About". Look for the "Network Provider Lock" option to determine whether your device is carrier locked or unlocked.

3. Back up valuable iOS files

While changing SIM cards does not directly involve iPhone data, it is highly recommended to back up your iPhone to a computer or cloud storage as a precautionary measure. This includes important contacts and media files that could potentially be subject to physical damage during the SIM card swapping process. To make it easier, you can get the professional product - MobiKin Assistant for iOS.

5. Power off iPhone while switching SIM cards

To ensure a smooth operation and prevent any potential software issues when moving SIM card to new iPhone, you're recommended to power off your iOS device during the switch. By turning off the device, you can avoid unnecessary complications and streamline the overall procedure.
