I changed my mobile phone card. Do you still have a record of the text messages?

If you change it in a short time, the text message is still there, but it won't be displayed when someone calls, unless you send a text message to inform you that your phone is turned off, but that will cost you. Generally speaking, SMS should be visible 24 hours after you switch back to your sim card. If you are afraid of someone calling the original number, you can set up call forwarding!
