Spam calls ?? Should I do something about it ?

Hi.
Today I received 7 calls from similar numbers (514)-501-****
Last 4 digit were different every time.
All calls I answered to were silent for 2 or 3 seconds then it was hanging up.
I answered the first 3 calls before I noticed a pattern. Then 4 remaining calls I didn't answer at all.
I also received 2 robot calls from "the Canadian government" ... Yeah right.
I'm more concerned about the 7 silent calls. Could it be an attempt to hack my line / sim card ?
Should I do something about it ?
