What Apple lists for the iPhone 12
Apple's SIM types page lists iPhone 12, iPhone 12 mini, iPhone 12 Pro, and iPhone 12 Pro Max as supporting eSIM. Apple places all 4 models under eSIM and nano-SIM, so the family includes a physical SIM tray. The date published with Apple's SIM types page is September 17, 2026. Apple's China mainland note names only a short list of the newest iPhone models as supporting eSIM there, and the iPhone 12 family is not on it.
The iPhone 12 Dual SIM combination
Apple's Use Dual SIM on iPhone page names iPhone 12 for 1 physical SIM with 1 eSIM. The same page does not name this family for 2 eSIMs. Its two-eSIM list names iPhone SE (3rd generation), iPhone 13 and later. For the iPhone 12 family, Apple's model listing is eSIM plus nano-SIM. The 2-eSIM description therefore applies to the models Apple names in that separate list, while the iPhone 12 entry gives the 1 physical SIM with 1 eSIM combination.
What the tray means for travel
The eSIM and nano-SIM listing gives each iPhone 12 model a physical SIM option alongside eSIM. That matters when a travel plan or local service uses a nano-SIM, because the phone has the tray Apple lists for that format. The eSIM remains another available method when the carrier or provider supports the plan. The two formats give a traveler different ways to connect, depending on the service offered for the trip. The SIM tray identifies the phone's physical-SIM format, while the carrier or provider determines whether its eSIM plan works.
Checks before choosing an iPhone 12 eSIM plan
Apple's Dual SIM note says physical SIM is not supported on all models and eSIM is not available in all countries or regions. Check that the carrier or provider supports eSIM for the plan. Apple's saved pages do not cover unlocking or installation steps, so confirm those with the provider. These checks concern the phone, the carrier, the region, and the particular plan, so the family listing alone does not answer every plan-availability question.
