После смены сим карты вся переписка в iMessage пропала

Hello tereza149.

Do you store your messages in iCloud? If not, without a backup, there isn’t a way to retrieve your iMessages. If you do store your messages in iCloud, are you signed in with the same Apple ID that you previously used? Here’s more information on storing messages in iCloud: Store messages in iCloud - Apple Support

Let us know if you have further questions.

Take care.
