Supported SIM arrangement
Apple lists iPhone 11 among models that support Dual SIM using a nano-SIM and an eSIM. Only one cellular data network is used at a time.
The model does not have the later iPhone 13 capability to operate two active eSIMs.
Regional exceptions
Purchase region matters. Mainland China models use different physical-SIM arrangements, and availability can differ in Hong Kong and Macao.
Identify the model and look for an EID before purchasing a travel eSIM.
Travel configuration
Keep the home line for calls and authentication and assign mobile data to the travel eSIM. Turn off Cellular Data Switching to prevent fallback charges.
The device must be carrier-unlocked to use two different carriers.
Options at a glance
Options at a glance table 1| Option | Scope | Main use | Important boundary |
|---|

| Travel line | eSIM | Mobile data | Enable roaming on travel line |
| Data switching | iOS setting | Potential fallback | Usually disable |
What this means in common travel situations
Home nano-SIM plus travel eSIM
This is the normal travel arrangement. Keep the home number on the physical SIM, assign data to the travel eSIM and disable Cellular Data Switching if fallback roaming would be expensive.
Two travel eSIMs at once
iPhone 11 cannot keep two eSIMs active simultaneously. A traveler changing countries should switch stored profiles or use the physical slot for one line.
China mainland purchase
Do not rely on the product name alone. Check the model number and EID because regional physical-SIM hardware differs.
