What is an effective way to seek a call from any phone station when not using a repeater?
Why CQ is the universal invitation on voice and CW meaning "calling any station." The standard simplex format is a short series of CQs, then "this is" and your call sign, then release and listen for a few seconds before repeating. Repeating the call in short cycles while listening between them gives stations tuning across the band a chance to find you and reply.
Watch out "QTC" is a Q signal meaning "I have a message for you," not a general call, and sending an unmodulated carrier is just a test transmission that tells listeners nothing and isn't a call for contact.
CQ sounds like "seek you": call CQ, identify, then listen.
