iPhone 13 Sim card use abroad

Hello SusanfromIGH,

You wouldn't be able to use the same eSIM on your iPhone 13, because these regions wouldn't have supported carriers throughout each region. The supported wireless carriers can be found using: Wireless carrier support and features for iPhone in Asia-Pacific - Apple Support (Select the appropriate region at the top for more reverent information.)

However, it does support up to 8 eSIM cards, with 2 active at a time.

Learn about the benefits of traveling with eSIM

eSIM offers many benefits while you travel abroad. It's more secure than a physical SIM because it can't be removed if your iPhone is lost or stolen. With eSIM, you don't need to obtain, carry, and swap physical SIM cards (which can also be lost), or wait for them to arrive by mail.

On your iPhone, you can store eight or more eSIMs, which will be there whenever you need them. You can have two eSIMs active on supported iPhone models at the same time. This could, for example, include one eSIM for your home and another eSIM for the place you're visiting. You can swap which of your stored eSIMs are active simply by changing your selections in Settings. This might be helpful if you travel regularly to the same places.

Your carrier might also offer the ability to manage your eSIM plan digitally and add more data as needed.

Hoping this helps out, take care.
