Is it possible to switch SIM cards while making calls on an iPhone iOS?
We often receive questions regarding the ability to switch SIM cards while on a call on an iPhone. The answer is no; you cannot switch SIM cards while actively on a call. If you're using a dual SIM setup, like an eSIM and a physical SIM, you can choose which line to call from before the call starts. Once the call begins, it is locked to that line until you hang up and switch the SIM card manually.Can you just switch SIM cards in iPhones?
Yes, you can switch SIM cards in iPhones. Generally, you can insert any SIM card you want, and it should work without issues. The main exception is a SIM card or phone that is locked by the cellular provider, though locked iPhones are becoming less common as many people opt for contract accounts that must be paid for to receive a SIM card.Is my SIM or phone locked?
Only the SIM card holder or the authorized account holder can contact the cellular company to determine if they are locked. If you forgot or do not have the right information, contact the cell phone provider for assistance.Step-by-Step Guide to Switching SIM Cards on an iPhone
