There is a new scam or a variation of an old scam floating around which will claim that your Apple ID password needs to be reset.
Do not click that link.
In fact do not click SMS links in general that may take you to third party sites such as banking SMS links that say there is an issue with your account.
Banks will not use this and if you believe there is an issue with your account - phone the bank and if you believe there maybe an issue with your Apple ID , logon to check your Apple ID at Apple to check.
These scams are designed to get your personal details , passwords etc
