Yes, "SIM Card Editor" software can potentially allow you to edit telephone numbers on your SIM cards using Windows 7 or 10, but you will also need compatible hardware. Typically, you will need a SIM card reader that connects to your computer via USB. Once connected, the software can read and modify the contact information on your SIM card. Ensure that both the software and hardware are compatible with your specific SIM card type and Windows version. Be aware that editing SIM card data could lead to data loss if not done carefully, and not all SIM cards allow modifications.
