Tip 2. Important Things to Consider

Whether you have a new or old iPhone, you are always advised to check a few things so your essential data is always under your control. As you already know what happens if you switch SIM cards in iPhones, here are some of the things you must check before swapping your old SIM card for a new one.

1. Check if your iPhone is Carrier-locked

Changing the old SIM card on an iPhone is pretty easy. But before you proceed with the process, check whether your iPhone is network unlocked. If your iPhone is already locked to a particular carrier, switching your SIM card to this iPhone may result in several complications. These issues usually prevent your iPhone from functioning with your desired network provider, limiting the iPhone's functionality and hindering your ability to use certain features or services on the device. This issue is particularly prevalent when using a SIM card from a carrier other than the one your iPhone is locked to.

Here are these detailed steps to check if your iPhone is carrier-locked.

• Open iPhone Settings.
• Click General and tap About.
• Scroll until you find the Network Provider Lock or Carrier Lock to see your network carrier lock status.

Note: You have to unlock your iPhone carrier. Either use a third-party iPhone unlocker service or contact the authorized network provider's shop to unlock it hassle-free.

2. The SIM Card Must be Compatible With Your iPhone

Some SIM cards do not operate on iPhones due to their incompatibility. You must know that iOS devices are compatible with nano-SIM cards only. So, if the new SIM card you want to use is not nano, you cannot use it with your iPhone. Therefore, always check the SIM card type before purchasing and ensure its compatibility with your device.

3. Transfer the Stored SIM Card Contacts to Your iPhone and Create a Backup

Transfer contacts to your new iPhone so that you can access them even after changing the SIM card. Although iPhone data is not directly involved in the process, it is best to back it up. This includes all the essential contacts and media files that are prone to physical damage while changing the SIM cards.

4. Turn Off your iPhone While Switching SIM Cards

Consider turning off your iPhone while changing SIM cards to avoid any software anomalies. Turning off your iPhone can save you the drill.

Tip 3. Essential Things to Prepare
