A caller from a UAE number asked me to call back but didn’t explain why. I’m not comfortable returning the call without checking it first. Can I find community reports or basic carrier information?

I’d be reluctant to return the call when someone gives no explanation and simply asks me to call back. That doesn’t automatically mean anything suspicious is happening, but checking the number first seems reasonable. You may find reports from other users or basic information about the number’s network. I’d search it using https://searqle.io/who-called/united-arab-emirates-reverse-phone-lookup/ and compare any reports with what actually happened during the call.
