I understand you're concerned about transferring your SIM card to a new phone and whether it will carry over all your data. So, let me ask you this: Are you wondering if your contacts, messages, and other personal information will seamlessly move from your old phone to the new one simply by inserting your SIM card? Or are you concerned about more technical aspects like network settings and phone numbers being automatically configured on the new device? Understanding the specifics of your concern will help me provide a more accurate answer.
