Inserting an old SIM card into your phone generally activates the phone with the same phone number and carrier settings associated with that SIM. Contacts and text messages stored on the SIM become accessible, though you may lose access to newer features if the SIM is outdated. Performance issues could arise if network standards have changed, but it's a practical way to check and use old data.
