iPhone stolen, today I received a scam text message and I fell for it. What should I do?

I got my phone stolen at edc this year and it took a while for my phone to get located, but once it was located (yesterday), it was found in China.

This morning I received a text from apple.za.id.imessage@icloud.com saying "dear apple customer, the system has detected that your lost iPhone is activated with a new SIM card inserted..." Then I got another text saying " Your iCloud 'photo stream' information is being restored into the iPhone of ___. As this is a remote synchronous operation, you are strongly recommended to timely access https://apple.com.gps-id.us/us and click the 'interception' at the upper right to invalid this operation if it is not done by you in person."

Me being the sleepy person I was, I signed into my apple ID on the link provided, then when I clicked 'sign in' nothing happened. I realized I totally just fell for a scam and changed my password to something completely different. What else should I do to make sure I'm okay??
