Can I insert Android SIM into my iPhone?

Yes, if the SIM card will fit into your phone......AND......your iPhone is not locked to a carrier that does not match the SIM card.

Note that if you purchased an iPhone 14, iPhone 15 or iPhone 16 in the U.S.......those models are eSIM only. They will not support a SIM card.

The Apple migration tools will either move the cellular plan for you, or will prompt you to relocate the nanoSIM, or will direct you to contact your carrier to transfer your plan, depending on the details of the particular carrier, devices, and migration.
