Welcome to Android Central! Open your Contacts app and see if there's an option there to filter your contacts by storage location.

Your SIM card is used to authenticate your user account with your carrier, or in other words your SIM verifies you to use your carrier's cellular network. It's not necessarily a storage media you (the user) will be storing data on.
Your text messages are directly tied to your text messaging service (i.e. the phone number assigned to by your carrier, or if you're using a third-party service like WhatsApp) so your messages are retained in your phone's internal storage media and/or your chosen text messaging service's online servers.and then you interact with them via whichever text messaging app you're using.
Your contacts are a separate matter.The contacts database that contains all your contact entries is also stored in your phone's internal storage, and if you have syncing enabled, concurrently with your email service's online servers.
So just to clarify, your '...sim card messages/contacts...' question is a bit misleading as you're just using three keywords to things that are only incidentally related to each other. Please elaborate and provide more details as far as what happened and ,more importantly, what the resulting message actually stated.

@smvim, in the old days, contacts and messages could be saved directly to the SIM, correct? (I think some phones still allow importing a contact from a SIM card.) I think SIM cards could only store a maximum of about 250 contacts, so clearly it's not a good way to save contacts, but I think some people may still be doing it that way as a legacy thing.

I was under the impression this practice was dropped by the carriers many years back. But that's just supposition on my part and U.S.-centric so depending on just where the OP resides and which carrier they use, maybe that is still a thing. My mistake on not clarifying.

Yeah, even on my Pixel 6 Pro in the Contacts app, if I go to its settings and then Import, one of the options is SIM card. And the Google Messages app has "SIM Card Messages" as an option in its settings menu. It's weird that this archaic modality persists.
