I receive survivors benefits. If I work how much can I earn before losing benefits? Also why would social security call me?
If you're age 66 or older, there is no limit on the amount that you're allowed to earn and still draw benefits. If you are under age 66, the amount that you can earn without losing benefits varies from year to year. In 2016, you can earn up to $15,720, or $41,880 if you reach age 66 this year, without losing any Social Security benefits. In 2017, the amounts go up to $16,920, and $44,880 for those turning 66 next year.

As for your other question, Social Security could call you for any number of reasons. Just be cautious and make sure that you are actually speaking to a Social Security representative before giving them any personal information.
