Does the iPhone 13 series support eSIM?

Yes

The iPhone 13 series supports eSIM, so you can add a MobiSIM data plan by scanning a QR code — no SIM card and no trip to a store.

What you need on your iPhone 13 series

A phone that isn't locked to one carrier. If you bought it on a contract, ask the carrier to unlock it before you travel.
An internet connection (Wi-Fi is fine) while you scan the QR code.
The latest software update for your phone.

Dial *#06# on the keypad. If an EID number appears, your exact phone has eSIM — useful because some regional versions of a model don't.

Choose a plan for your destination and open the QR code from your email or from My eSIMs.
On the iPhone 13 series, go to Settings → Cellular → Add eSIM, then scan the QR code (or tap the install link on the phone itself).
Turn on data roaming for the MobiSIM line and you are online as soon as you land.
